What they were up against
Vaultly's founding team had a validated idea for a personal finance management tool but no technical co-founder. They needed to go from zero to a live product in 8 weeks to hit their investor demo deadline — with bank-grade security, a flawless UX, and the ability to process real money.
How we solved it
We co-created the product vision in week one, designed the full UI system in Figma, and handed off to engineering by day 10. We built the React Native mobile app and Node.js API in parallel sprints, integrated Stripe for payment processing, and deployed on GCP with automated CI/CD. Security review and pen testing happened in the final sprint.

Insights
Key learnings from this project
Hard-won insights our team took away — the kind of knowledge that only comes from building in production.
Starting design and engineering in parallel (with a shared component library) cut the total timeline by 30%.
Stripe's pre-built compliance flows eliminated 3+ weeks of custom payment security work.
Having a live staging URL from week 2 let the founder demo to investors early — that momentum closed their seed round.
