How we think
Ship the smallest thing that proves the idea.
Most software projects fail by building too much before talking to users. We scope a focused first release, ship it, measure it and grow it from real usage.
You get one senior team covering product thinking, UX, front end, back end, cloud and security, with a working build to review every week.
- Weekly demos: see progress on a live staging link
- Modern stack: React, Next.js, Node.js, Python and Postgres
- Secure by design: auth, roles, audit logs and encryption
- You own the code: in your GitHub from day one

Buyer guide
Planning a custom web app: cost, stack and timeline.
How much does custom web application development cost?
A focused MVP usually costs $8,000 to $25,000. A full SaaS product or complex portal with integrations typically runs $25,000 to $100,000 or more, built in phases. We price each phase separately so you only commit to what you can see.
Which tech stack do you use?
Usually React and Next.js on the front end, Node.js or Python on the back end, PostgreSQL for data, and AWS, Google Cloud, Azure or Vercel for hosting. We choose boring, well-supported technology your future hires will know.
Build vs buy
If an off-the-shelf tool covers 80% of what you need, use it and integrate. Build custom when the workflow is your competitive advantage or when licences for many users cost more than owning the software.

FAQ
Web App Development questions, answered.
Straight answers to what clients ask us most. Still curious? Ask us on WhatsApp.
Do you build MVPs for startups?
Yes. MVP development is a big part of our work: we help you cut scope to what proves the idea, then ship it in 6 to 10 weeks.
Who owns the intellectual property?
You do. Code lives in your repository, and IP transfers to you as each milestone is paid.
Can you take over an existing web app?
Yes. We start with a code and infrastructure audit, fix the riskiest issues first and then continue development.
Do you sign NDAs?
Yes, before any detailed discussion if you prefer.
Can you add AI features to our app?
Yes. We add AI search, assistants, document processing and agents with proper evals and guardrails. See LLM application development.
