FOUNDERCODE1
From your first day of self-employment to your first investor meeting, your first business loan, your first office, and eventually your exit — the Sialph Venture Circle is the ecosystem that grows with you.
Open to any business, anywhere in the UK. Free to join for Sprint graduates.
The Venture Circle is more than tools and introductions. Every month, your business tells us exactly where it is — wins, challenges, what it needs. We read every word. Then we go to work on your behalf.
For local businesses and community-rooted startups, the Circle does something additional: it matches you locally first, keeping the economic benefits of your growth in the community where your business operates. Local spending. Local hiring. Local wealth. Then wider, until you succeed.
WHAT IS THE VENTURE CIRCLE?
One ecosystem. Every resource a business needs to grow.
Most business support platforms give you a tool and leave you to it. The Sialph Venture Circle is different. It is a living, active matchmaking ecosystem where everything a business needs — tools, strategy, finance, workspace, investors, and buyers — is connected into a single, continuous relationship.
The difference is not the tools. It is what happens behind them.
Every month, every Venture Circle business tells us exactly what is happening — what they won, what they are struggling with, what they need next. At the same time, every business seeking a deal, a partner, a funder, or a joint venture tells us precisely what they are looking for. Our advanced match-making system identifies live deals, maps them against the full Circle, and originates the matches. Live deals. Real introductions. No waiting for someone to find you.
You do not need to go looking for a grant adviser, then a finance broker, then an accountant, then an investor. The Circle finds the right resource for you, at the right moment, because it already knows where you are.
We work in partnership with local authorities, organisations, and over 100 organisations including Reddit, Snapchat, and Xero.
HOW DOES THE VENTURE CIRCLE WORK?
One relationship. Your entire business journey.
The Venture Circle is not a one-off event or a single product. It is a continuous, active relationship — one where Sialph is always working on your behalf, not waiting for you to come to us. Here is what powers it.
PROGRESS SUBMISSIONS
Once a month — or once a week if you want us closer — you tell us exactly where your business is. What you won. What you are struggling with. What you need most right now.
This is not a report for a database. It is the signal we use to go to work on your behalf.
When you tell us you landed your first corporate client, we look across the Circle for other members who need an introduction to that sector. When you tell us cash flow is tight, we check which finance partners are right for your stage. When you tell us you are ready to raise, we brief the investors already waiting in our network. When you share a challenge, we look for a member who has solved it.
Every Progress Submission is read. Every one generates action. The more you share, the more the Circle can do for you.
Your submissions are kept strictly confidential. We will only share your wins publicly — in community updates, case studies, or press releases — with your explicit permission.
DEAL MEMO
When you are actively looking for something specific — equity capital, a debt facility, a joint venture partner, a strategic buyer, a co-founder, a property, a supplier — you submit a Deal Memo.
A Deal Memo is not a wish list. It is a precise, structured brief that tells us exactly what you are looking for, on what terms, and by when. You can have multiple active Deal Memos running simultaneously — one for fundraising, one for a commercial partnership, one for workspace. Each one triggers a separate search.
Our team takes each Deal Memo and works through the full Venture Circle — and beyond it into our wider network of investors, lenders, advisers, and operators — to find the right match. When we find one, we make a warm introduction. We brief both parties in advance. We do not send cold emails.
Together, the Progress Submission and the Deal Memo give us an exceptionally clear picture of every business in the Circle at any given moment. That picture is what allows us to spot joint venture opportunities, identify businesses that should be talking to each other, and move quickly when the right match appears.
This is matchmaking at a scale and with a level of human attention that no algorithm alone can replicate.

One hour that changes your 90 days
Book a Startup Sprint (for founders and early-stage businesses) or a Local Sprint (for established local businesses). One hour, one urgent priority, one clear action plan. You leave with something you can use the same day.
Every Sprint graduate joins the Venture Circle free for life. That means the hour you spend is not just strategy — it is the door into everything else.
WHO THIS IS FOR: Any business at any stage that needs clarity, momentum, or a second opinion from someone who has seen it before.
Every type of funding, mapped to your stage
The Venture Circle connects you to the right funding at the right time. Not a directory of lenders to approach yourself — active introductions, made when your Progress Submissions and Deal Memos tell us you are ready. The range covers every stage a business goes through:
Working capital and Revenue Based Finance for businesses generating turnover. Invoice and asset finance for businesses with equipment or unpaid invoices. Commercial bridging and development finance for property and infrastructure. SEIS and EIS angel investment for early-stage startups. Venture capital for high-growth companies scaling fast. PE and acquisition capital for businesses ready to sell or take on a growth partner.
We also work with members on aggregated deal structures — where multiple Venture Circle businesses come together to raise or borrow collectively, reducing fees and preserving more equity. This is available by invitation where the right conditions exist across the Circle.
WHO THIS IS FOR: Any limited company looking for capital — from first revenue to growth stage to exit.
Affordable workspace across SE London, and the UK
We are building a portfolio of affordable workspace locations — from SE London borough developments to partner venues across the UK — exclusively for Venture Circle members. Flexible terms, below-market rents, and the added benefit of being surrounded by other Circle businesses.
This is not a hot-desk directory. When a workspace opportunity comes up that matches a member’s Progress Submission or Deal Memo, we make the introduction before it goes anywhere else.
WHO THIS IS FOR: Businesses that need a physical base and want it as part of a wider business community, not just a room to work in. Launching soon — submit a Deal Memo now to be first in the queue.
Real investor introductions. Not a matchmaking database.
The investors in the Venture Circle — angels, VCs, PE firms, and strategic buyers — do not receive a database to browse. They receive curated briefings on specific businesses that match their investment thesis, built from the Deal Memos and Progress Submissions that our members submit.
This means when an investor hears about your business through the Circle, they already know your traction, your current challenges, and exactly what you are looking for. The first conversation is a real conversation, not a cold pitch.
And because investors pay to be in the Circle — not for the right to invest, but for the quality of the deal flow they receive — they are motivated to move when a good match comes through.
When your Deal Memo says you are raising and your Progress Submissions show the traction to back it up, we go to the right investor. Not every investor. The right one.
WHO THIS IS FOR: Any business preparing to raise equity, secure debt, or explore acquisition — at whatever stage you are at.
Acquisition Ready. On your terms.
Exit is not the end of the Circle — it is one of the most active parts of it.
When the time is right, the Acquisition Ready programme prepares your business for sale with a structured process: management accounts review, Information Memorandum, buyer identification, and warm introductions to PE firms and strategic buyers who are already paying for access to exactly this kind of pipeline.
Because PE subscribers see your Progress Submissions over time, they understand your business before the first conversation. That makes the process faster, more direct, and more likely to result in a deal that works for you.
WHO THIS IS FOR: Owner-managed businesses thinking about succession, exit, or taking on growth capital in the next one to five years. The earlier you tell us, the better we can prepare you.
Unique opportunities, every time.
The Circle works in expanding circles — not just as a metaphor, but as the actual logic of our matching engine.
For any member, we start with the most relevant match available. For local businesses, that means local first — local customers, local suppliers, local investors, local partners. The search then expands: regional, national, international. The Circle does not stop until it finds the right match, wherever that match is.
This means a restaurant in SE London finds a local food supplier before we look nationally. A tech startup in Manchester finds a local angel before we approach London VCs. A property developer in Birmingham finds local planning expertise before we search beyond the Midlands.
But when the right match is not local, we go wider. A Venture Circle business whose product serves a national market gets national introductions. A founder whose investor thesis requires a sector specialist gets the best sector specialist we can find, regardless of geography.
Every member contributes to the Circle by sharing what they know, what they offer, and what they need. The more members contribute, the more the matching engine can do for all of them. This is the compounding effect of an ecosystem: every new member makes the Circle more valuable for everyone already in it.
THE VENTURE CIRCLE AND LOCAL ECONOMIC DEVELOPMENT
The Venture Circle creates something most business platforms do not: measurable, lasting economic impact in the communities its members operate in.
This is not a social mission bolted onto a commercial platform. It is the mechanism by which the Circle generates returns. When local businesses grow, they hire locally, spend locally, and build wealth that stays where it was created. The Circle accelerates that process deliberately.
Priority local matching
When a local business submits a Deal Memo, our matching engine looks locally first. A local supplier before a national one. A local investor before a London VC. A local workspace before a national chain. This keeps economic activity — spending, employment, investment returns — circulating in the local economy rather than leaking out of it.
Local startups building local economies
A startup does not need to be purpose-built for social impact to create it. A tech founder in Lewisham who builds a logistics platform and hires ten local people has created local economic impact regardless of their original intention. The Circle supports these founders at every stage — tools, finance, investors, customers — and the local economy benefits from every step of their growth.
Community infrastructure through Sialph Capital
Through Sialph Capital, the Circle originates private finance for community infrastructure — EV charging on council estates, battery storage on NHS land, broadband for underserved areas, and affordable workspace in new developments. These are assets that serve communities for 20–25 years. The businesses and local authorities that use them benefit from private capital deployed at community scale.
A platform built for economic inclusion
The Circle actively serves founders who face the greatest barriers to finance and investment — Black founders, female founders, LGBTQ+ founders, founders from self-employment programmes who are building from zero. Active matchmaking removes the barrier of not having the right network. The Circle is the network.
For grant bodies and impact investors:
The Venture Circle generates measurable community economic outcomes: businesses supported, jobs created, finance accessed, and community infrastructure originated. These outcomes are tracked through the Deal Memo and Progress Submission pipeline and can be reported at local, regional, or national level.
If you are a grant body, an impact-focused investor, or a local authority economic development team looking for a platform that delivers community economic impact alongside commercial returns — we want to hear from you. Contact us.
WHO IS THE VENTURE CIRCLE FOR?
The Venture Circle is open to any business, anywhere in the UK — and beyond. You do not need to be local to access the Circle’s deal matching, tools, finance introductions, or investor connections. If you are building something, wherever you are building it, the Circle works for you.
But for local businesses and local startups — businesses rooted in a specific place, serving a specific community — the Circle has an additional layer that makes it uniquely powerful.
For startups from anywhere:
You join the Circle, submit your Deal Memo, and we search the full UK ecosystem for the right match. Investors, lenders, tech partners, co-founders, suppliers — the Circle’s network is national and growing. Your geography does not limit what we can find for you.
For local businesses and community-rooted startups:
You get everything above, and something more. The Circle’s matching engine prioritises local introductions first — connecting local businesses with local customers, local suppliers, local investors, and local opportunities before widening the search. This is deliberate. Local business spending stays in local economies. Local hiring builds local communities. Local investment compounds local wealth.
The system works outward from your postcode: local Circle members first, then regional, then national, then global. You benefit from the whole network while anchoring the returns in your community.

- Digital Bundle: 90% off Xero, advertising credits, expert consulting sessions, and ongoing member-exclusive partner offers

For investors who want a curated edge
The Venture Circle gives you something that deal flow databases, pitch competitions, and accelerator demo days cannot: current, specific, human-curated intelligence on businesses that match exactly what you are looking for.
Every business in the Circle submits monthly Progress Updates — wins, challenges, current stage, what they need. Every business seeking capital, partners, or buyers submits a Deal Memo with precise terms and timing. Our team reads everything. When a business’s profile, traction, and ask align with your stated thesis, we brief you — specifically, not as part of a bulk email.
The businesses in the Circle come from two genuinely unusual pipelines. First, DWP self-employment referrals — first-generation founders from underrepresented communities, supported through our Sprint process from day one. Second, local authority and community organisation networks — established, revenue-generating SMEs that have never been on a pitch platform but are exactly the kind of businesses PE firms and strategic acquirers are actively looking for.
You do not browse our database. We come to you when the match is right. The quality of what we send you depends on how precisely you define what you are looking for — so the more specific you are, the more valuable the Circle becomes.
REGULATORY NOTE: Sialph charges a fixed annual subscription for deal flow access. We do not arrange investment transactions, provide investment advice, or earn success fees on capital raised. All investment decisions are made entirely by the subscriber. Sialph Ltd is not authorised or regulated by the FCA.
For partners who want access to a growing ecosystem
Venture Circle partners do not just get a logo on a page. They get access to an ecosystem where every business is actively telling us what they need — which means when a member’s Progress Submission or Deal Memo reveals a need for your product or service, we make the introduction directly.
The best partner relationships in the Circle are the ones where the partner contributes actively — offering a deal exclusive to Circle members, presenting at a Sprint session, or spotting opportunities to help businesses they can genuinely serve. The Circle rewards contribution with visibility. The more you give, the more the ecosystem sends your way.
The Venture Circle brings you direct access to 100,000+ UK businesses monthly — from day-one startups to established SMEs to investment-ready growth companies — alongside the VCs, PE firms, and angels who invest in them.
Whether you provide software, professional services, insurance, marketing, legal advice, or financial products, the Venture Circle gives you a structured, trusted route into a growing business community.
WHAT PARTNERS GET:
- Speaking and workshop opportunities at Sprint sessions and Demo Days
- Access to offer your products to Circle members as part of the exclusive tools bundle
- Direct introduction to VC and PE subscribers who need services for their portfolios
- Co-branded campaigns where applicable
- Discounted option to promote your business on the Sialph Marketplace

FREQUENTLY ASKED QUESTIONS
The Venture Circle is a community business growth ecosystem that connects businesses with everything they need to grow — from free digital tools and business strategy support through to funding, workspace, investors, and ultimately acquisition or exit. It is free to join for any business that completes a Sialph Sprint (or invited).
Everyone in the Circle contributes by offering opportunities or participates in networking and joint ventures.
Any UK business can join the Venture Circle via a Startup Sprint (£500) or Local Sprint (£500). You can use apply to join the Venture Circle via the direct membership route (see below). Alternatively, you may be directly invited to join or via one of our sponsored onboarding events (i.e. in partnership with other Venture Circle parties).
Investors, VCs, PE firms, and corporate buyers can join as a separate membership level. We will prioritise deals that you are looking to finance or businesses to acquire from our internal deal flow, plus our own built AI industry research tools.
We create multiple and unique opportunities for you to get involved with businesses within the community.
: When you submit a Deal Memo — for a fundraise, a joint venture, a partnership, a property, or anything else — our team takes it and works through the full Venture Circle to find the right match. We look at every other member’s current profile, their Progress Submissions, and their own active Deal Memos. When we find a match, we brief both parties independently and, with consent from both sides, make a warm introduction.
You can have multiple Deal Memos active at the same time — for example, one for a £150,000 equity raise and one for a co-marketing partnership. Each one triggers a separate search. There is no additional charge for submitting Deal Memos. It is part of what membership is for.
We do not guarantee that every Deal Memo will result in an introduction. Some are very specific, some require a counterparty that does not yet exist in the Circle, and some need time. But every submission is read and every one is actively worked. We will always let you know what we have found.
Your monthly (or weekly) Progress Submission is read by our team — not filed in a database. What you share tells us three things: what you have achieved (which we can help you promote and build on), what you are struggling with (which we can often solve by connecting you to the right person in the Circle), and what you need next (which we match against other members’ Deal Memos and capabilities).
A member who says their biggest challenge this month was finding a reliable packaging supplier might be matched the same week with a Circle member who supplies exactly that. A member who reports landing a corporate contract might be introduced to an investor who specifically backs businesses at that stage. These connections happen because we are reading the whole Circle simultaneously — something no individual member can do alone.
Through the Venture Circle, businesses can access Revenue Based Finance, invoice finance, asset finance, commercial bridging, development finance, and SEIS/EIS equity investment. We do not send you to a list of lenders to apply to yourself. When your Progress Submission or Deal Memo tells us you need finance, we identify the right lender or investor from our panel and make the introduction directly. We earn a fee from the lender when a facility completes — never from you. All finance introductions are for limited company borrowers. Sialph Ltd is not FCA authorised and does not provide financial advice or arrange regulated investment transactions.
HMRC’s Making Tax Digital for Income Tax becomes mandatory in April 2026 for sole traders earning over £50,000. The threshold drops to £30,000 in 2027 and £20,000 in 2028. This means the vast majority of self-employed people in the UK will eventually need to use HMRC-approved accounting software like Xero. Through the Venture Circle’s Digital Bundle, businesses in our partner boroughs can access Xero at 90% off — making MTD compliance affordable from day one.
By our own inhouse built analytical systems we analyse all Circle members Deal Memos, Progress Submissions to identify opportunities, match organisations with others who help solve each other’s problems and even create new opportunities by spotting community trends.
What this means that, not only will you be able to find resources that your business needs (i.e. marketing software or finance), but you may also find opportunities with live deals.
For example, if you are a bakery and in your Deal Memo you have stated you want some property finance to fund a development of a larger bakery, we will actively seek to source or support you in this. However, another Circle member’s Progress Submission may show that they are planning a local event and might need catering to support that event – in which we will make a warm introduction to both as a recommendation.
The Venture Circle is free to join because Sialph earns from the deals it originates — not from membership fees.
When we identify a match between two parties — a PE firm and a developer, a local authority and an infrastructure partner, a business and a funder — and that match results in a completed transaction, Sialph charges an origination fee. On commercial property and infrastructure deals, this is typically 2.5% of the total transaction value, charged to one or both parties depending on the nature of the deal and agreed in writing before any introduction is made.
You always know the fee before the introduction happens. You never pay a fee unless a deal completes.
This model means our interests are directly aligned with yours. We only earn when the match works. The better the brief you give us — through your Deal Memo and Progress Submissions — the faster we find the right counterparty, and the more likely the deal completes
Sialph is not authorised or regulated by the Financial Conduct
Authority. We do not give investment advice, arrange regulated investment transactions, or act as a consumer credit broker. We introduce limited company borrowers to commercial finance lenders (an unregulated activity), charge fixed advisory fees for grant and SEIS/EIS preparation (advisory services), and charge fixed subscription fees for investor deal flow access.
