How It Works
Building a startup product is different from building business software. Speed matters, but so does building on a foundation that won't collapse when you hit traction. We act as your technical co-founder for the build phase — handling architecture decisions, infrastructure, and development so you can focus on customers and fundraising. The result is a production-grade product built on scalable infrastructure with analytics baked in from day one.
Not sure what the right first step is?
Show me the workflow or system causing problems. I’ll help identify the simplest sensible next step.
Directly with James. No sales presentation. No obligation.
One workflow is enough to start.
Bring the spreadsheet, handoff or system that is slowing the team down.
Our Process
Product Strategy
We help you prioritise features, define your user journey, and identify the metrics that matter for your stage.
Architecture & Build
Scalable infrastructure from day one. No rebuilding when you hit 1,000 users or raise your next round.
Analytics & Launch
User analytics, error tracking, and performance monitoring built in. Launch with visibility into how people actually use your product.
Iterate & Scale
Post-launch iteration support to respond to user feedback, improve retention, and prepare for scale.
Frequently Asked Questions
How is this different from MVP Development?
MVP is about testing one hypothesis fast and cheap. Startup App Development is a fuller engagement — product strategy, scalable architecture, analytics, and ongoing iteration. Choose MVP to validate an idea. Choose this when you know the idea works and need to build the real product.
Can we bring our own designer?
Absolutely. We work well with external designers. You provide the designs (Figma preferred), we implement them pixel-perfect. If you don't have a designer, we handle the UI as part of the build.
What tech stack do you use?
Next.js, React, TypeScript, Supabase (Postgres), and Vercel. This stack is fast to build on, scales well, and has a massive developer community — so you can hire other developers to continue the work if needed.
