Annual plans — built for commitment, not churn

Biosource offers annual plans only. This ensures every buyer and supplier builds real, lasting relationships — not one-month transactional visits. Plans scale with your organisation's size.

Why annual plans only?

Sustainable sourcing is a long-term commitment. Annual plans ensure buyers build genuine supplier relationships, accumulate CSRD compliance data, grow their Biosource Sustainability Score, and earn carbon credits over time — not just for one sourcing cycle. Suppliers deserve committed buyers. Annual plans make that possible. The 24-month non-circumvention clause applies from first contact.

Transaction fee: A 1.5% fee applies to all orders processed through the Biosource platform above €1,000. This is automatically calculated at checkout and covers payment protection, verification record-keeping, and dispute resolution. No fee on sample orders below €500. This fee is lower than a corporate credit card (2–3%) and generates carbon credit data and CSRD records in return.

Our path to unicorn status

We build this platform to last. Here's our honest revenue model at scale, so you can see why Biosource is built to endure — not just survive.

Revenue model at scale

Buyer subscriptions · 5,000 orgs × avg €2,400/yr€12M ARR
Supplier subscriptions · 10,000 suppliers × avg €350/mo€42M ARR
Transaction fees · 1.5% on €3B annual GMV€45M ARR
Advertising revenue€8M ARR
Materials intelligence terminal subscriptions€18M ARR
CSRD compliance backbone licences€28M ARR
Biosource Finance (invoice factoring, carbon brokerage)€35M ARR
Data intelligence, API access, testing & validation€8M ARR
Total at scale ~€196M ARR

At a conservative 8× ARR multiple, Biosource reaches unicorn status (~€1.6B). At 15× — typical for high-growth marketplace infrastructure — valuation reaches €2.9B. AI verification infrastructure, CSRD regulatory lock-in, and the AI data flywheel create durable moats that compound over time.

Common questions about annual plans

Why annual plans only? What if I just want to try for a month? +
We offer a generous free tier for exploration. Monthly plans would allow buyers to join, extract value (use AI discovery, get supplier contacts, close a deal), and cancel — leaving suppliers with no ongoing relationship and Biosource without the revenue to maintain the platform. Annual plans mean you're a serious participant. The free tier lets you verify the platform is right for you before committing.
What is the non-circumvention clause exactly? +
Any buyer and supplier introduced through Biosource must transact through the platform for 24 months from first contact. If you transact offline after a Biosource introduction, a 3% introduction fee of the first year's transaction value is owed. This is standard in deal origination and marketplace platforms. It protects the suppliers who invest time responding to your RFQs. We explain this clearly at sign-up — it's not buried in small print.
Can I cancel an annual plan mid-year? +
Annual plans are non-refundable but we'll work with you if your circumstances change significantly. We don't charge punitive exit fees. You can always downgrade to the free tier at renewal. We'd rather keep you happy at a lower tier than have you leave angry — your referrals matter to us.
What counts as a "transaction" for the 1.5% fee? +
The 1.5% fee applies to confirmed purchase orders placed and processed through the Biosource platform, above €1,000. Sample orders, RFQs, and introductions are free. The fee is automatically calculated at checkout. It does not apply to ongoing orders from the same supplier-buyer pair where the introduction predates Biosource membership (i.e., existing relationships you bring to the platform).
How does the Pioneer equity programme work in practice? +
Qualifying startups grant Biosource a 1–2% equity stake via a SAFE note — the same instrument used by YCombinator and thousands of seed investors. Biosource has no board rights, no operational involvement, and no preference shares. In exchange, you get 24 months of full platform access (both buyer and supplier capabilities), co-marketing, investor introductions, and quarterly impact reports. The equity is worth nothing today; the platform access could be worth hundreds of thousands of euros in closed deals.
Do buyers see which materials are "Sponsored"? +
Always. Every sponsored placement is clearly labelled "Sponsored" in amber — similar to Google Ads labelling. Biosource's credibility depends on buyers trusting our AI matching. We would never secretly rank a material higher for payment without clear disclosure. Sponsored placements only appear in categories where the material is genuinely relevant.

Have a question? Let's talk.

Whether you're a buyer exploring your options, a supplier wanting to list your materials, or curious about the Pioneer programme — we'd love to hear from you.
