MVP development and technical advisory for startups
Ship an MVP in as little as 2 weeks; partner on investor narrative, product roadmap, and early-user acquisition.
Common pain points in this industry
- Engineering hiring is delayed and product hypothesis validation stalls.
- Without a CTO / technical lead, architectural decisions are stuck.
- Seed / pre-seed budgets do not allow large development spend.
What we deliver
Rapid MVP development
MVPs deliverable in as little as 2 weeks on a Next.js + Prisma + PostgreSQL + Vercel standard stack. End-to-end from requirements through UI design, implementation, and launch.
AI pipeline integration
Embed bespoke AI features built with Claude / Gemini / Dify into the MVP. Reference: our own daily-running video generation pipeline.
Tech advisor / Fractional CTO
4-8 hours/week tech advisory: architecture review, hiring support, investor-deck tech narrative, and code reviews.
