04 — Questions founders ask

Before you book.

What exactly do you deliver in 30 days?

We deliver a fully functional MVP including frontend interface, backend API, database setup, user authentication, responsive design, and production deployment. Everything needed to start acquiring users and validating your product idea in the market.

What happens if you don't deliver in 30 days?

If we don't deliver your MVP within 30 days as specified in our agreement, you get a full refund plus $2,000. No questions asked. This is our commitment to accountability and quality.

What technologies do you use?

We use modern, battle-tested tech stacks: React/Next.js for frontend, Node.js/Python for backend, PostgreSQL/MongoDB for databases, and AWS/Vercel for deployment. We choose the best tools for your specific needs.

How is the retainer service different?

Our retainer service gives you a dedicated senior developer for ongoing work. You get 60 hours monthly to add features, fix bugs, improve performance, or pivot your product. It's like having a CTO without the full-time cost.

Can I pause or cancel the retainer?

Yes. You can pause or cancel your retainer with 7 days notice. No long-term contracts, no cancellation fees. We believe in earning your business every month through exceptional results.

What kind of MVPs have you built?

We've built SaaS platforms, marketplaces, AI-powered tools, fintech applications, and more. From FeedbackFlow (feedback widget tool) to Symphsys (homeopathy AI chatbot) to Schedullr (Notion to LinkedIn scheduler). Check our work section for examples.

Do you build compliance and document-intelligence software?

Yes. We build geotechnical CoA screening, CQC inspection readiness tools, funder impact reporting, and evidence packs for regulated documents. The system extracts what is on the page and refuses to invent values. See compliance software.
