We built this because we needed it.
In 2024 we were two indie engineers paying $99/mo for a markets API on a portfolio tracker that hadn't yet earned a single euro. Every month, logging into the dashboard felt like watching ourselves get slowly portioned out of our own runway. The provider was fine. The data was fine. The price was just wrong for the use case.
We looked at the budget incumbent — $29/mo, no fundamentals on the entry tier, no proper EUR invoicing, no SEPA. We looked at the legacy provider — $499/mo plus a sales call. Neither served indie devs. Both seemed to assume that everyone shipping fintech is either a bedroom hobbyist who doesn't deserve fundamentals, or a bank with a six-figure data budget.
So we built the thing in between. €19/mo is the price we wanted to pay ourselves. 15-minute delayed quotes is the level of fidelity we needed. Fundamentals on the entry tier — yes, even on Indie — is the obvious thing nobody else does because it makes the spreadsheet harder.
What we believe
- Honest scope beats marketing. We are not a real-time SIP feed. If you need tick-level data, we'll send you to someone who has it.
- Indie devs deserve fundamentals. Splits, dividends, corporate actions, 10y of statements — these are not premium add-ons. They are table stakes.
- Pricing should be in your currency. EUR-first, with proper VAT and SEPA. Not because we're against Americans — but because most indie SaaS pricing pretends Europeans don't exist.
- No surprise bills. Soft caps with HTTP 429. We email you when you hit the ceiling. We never auto-bill overage.
- Building in public. Roadmap, ARR, infrastructure cost — we publish them. We make mistakes on a public timeline so the next indie dev API doesn't repeat them.
Building in public
Our roadmap is on GitHub. Our changelog is the blog. We post a quarterly metrics update with ARR, gross margin, and infrastructure spend. The point is not transparency theater — it's that we want the next indie API builder to have the playbook we wish we'd had. If you're building one yourself, our DMs are open.
Where we are
Incorporated in Ireland. Servers in EU-West (primary) and US-East (secondary). The team is currently 2 founders + 1 contractor in 3 time zones. We will probably stay deliberately small for as long as we can.
