How can I get a quote?

Jump on a free strategy call with our founder, Alex. You can schedule here or reach out to us directly.

How long will it take to complete my project?

Most projects ship in 6–10 weeks. Timeline depends on feature complexity — AI coding tools let us move 3–5x faster than traditional dev shops without cutting corners on quality. Schedule a call for an exact estimate based on your scope.

What is AI-powered app development?

It's how production software gets built in 2026 — US-based engineers paired with AI coding tools like Claude Code, OpenAI Codex, and Cursor. You get real production code (React, Next.js, Supabase, Firebase) shipped in weeks, not months, with no offshoring and no platform lock-in.

Can AI-coded apps handle complex production workloads?

Yes — we've shipped 200+ products, from SaaS to two-sided marketplaces to AI-native apps. Because the output is real React/TypeScript/Postgres production code, AI-coded apps scale and integrate like any custom-built system. No platform ceiling, no vendor lock-in.

What happens after the application is deployed?

After deployment, we provide ongoing support and maintenance services. This includes regular updates, bug fixes, and addressing any changes. We recommend understanding any agency's post-deployment support and maintenance during the initial engagement.
