A Madrid fintech startup had 3 weeks until demo day and no CTO. Collybrix shipped the MVP anyway.
MVP in 10 weeks
€450,000 raised
Total cost <€40K
0% equity given
Three weeks before a pivotal accelerator demo day, M.A. was facing a founder's worst nightmare: her technical co-founder had accepted a full-time offer at a major bank, leaving the startup's core SEPA payment reconciliation platform entirely unbuilt.
M.A. had everything a pre-seed fintech needs to raise — a validated market, signed letters of intent from 3 enterprise customers, and live investor interest from two Spanish VCs. What she didn't have was a product.
"I had committed to a live demo in front of 80 people. I couldn't back out, and I couldn't show a slide deck. I needed a working product — and I needed it in 10 weeks."
Within 48 hours of the first call, Collybrix had reviewed M.A.'s specification, identified the minimum viable scope that would satisfy both investors and her enterprise customers, and mapped a 10-week delivery roadmap with weekly milestones.
Collybrix acted as technical co-founder from day one. Architecture decisions, bank API negotiations, and compliance requirements (PSD2, GDPR) were handled internally. M.A. received weekly async updates in plain language — no technical jargon — so she could focus on fundraising while the product was being built.
By week 7, three enterprise pilot customers had hands-on access to a testable MVP. By week 9, the product was demo-ready.

| Equity given | 0% |
“Collybrix saved the company — and I mean that literally. Without them, we would have missed demo day and lost the round. The ROI is the clearest number in our cap table. I'd do it again.”
