Who We Are

A focused studio that builds products people actually use

Discover More

Brain Stack is a small, senior team — two founders and a network of specialist engineers — working with ambitious founders and businesses across the US, UK, and Europe.

We don't run large teams where your project gets handed to juniors. When you work with Brain Stack, you work directly with the people who built the products in our portfolio. That's how we stay fast, sharp, and accountable.

We specialise in high-stakes digital products — fintech platforms, HIPAA-compliant healthcare systems, B2B marketplaces, and SaaS tools where security, compliance, and reliability aren't optional. Our team has shipped products handling real financial transactions and real patient data. When the stakes are too high for a no-code tool, that's when clients come to us.

The Team

Built by founders run by founders

Two senior builders and a trusted network of specialist contractors. Every project runs through us directly — no account managers, no hand-offs.

How We Engineer

How we work.

Let's Work Together

Discovery

STEP 01

1-2 Weeks

We start with your business, not your brief. We ask what you're actually trying to solve, who uses it, and what success looks like in 90 days. We ask the straightforward questions before a line of code is written.

ScopingFixed PriceFixed Timeline

Design

STEP 02

1-2 Weeks

Before we build, we map. Wireframes, user flows, and architecture decisions get agreed here. You review and approve everything before development starts. No surprises halfway through.

WireframesUser FlowsArchitecture

Build

STEP 03

4-8 Weeks

Jakir leads engineering. We build in sprints with weekly check-ins so you always know where things stand. You get access to a staging environment throughout — not just a demo at the end.

SprintsWeekly Check-insStaging Access

Launch & Beyond

STEP 04

Ongoing

We handle deployment and monitor the first 72 hours live. We don't disappear at go-live. Most clients continue working with us after launch because the product still needs to grow — we offer ongoing support and iteration on a retainer or project basis.

FAQ

Common questions

Projects start from £5,000 for a focused MVP or feature build. Full product builds — including design, engineering, and deployment — typically range from £12,000 to £40,000 depending on scope and complexity. We give you a clear fixed price before anything starts. No open-ended billing.

For a landing page or simple brochure site — honestly, you probably could. But if your product handles payments, user data, medical records, or business-critical workflows, AI-generated code creates real security and compliance risks. We build products where the architecture, data handling, and security are engineered properly from day one. Our clients choose us because they can't afford for it to go wrong.

A focused MVP takes 4–8 weeks. A full product with multiple features takes 10–16 weeks. We'll tell you exactly at the discovery stage — and we don't take on projects we can't deliver on time.

Both founders. Jakir leads the engineering. Kyaw handles communication, delivery coordination, and making sure what we build solves your actual business problem. You are never handed to a junior team or a subcontractor you've never met.

Yes — most of our clients are founders building their first or second product. We understand pre-seed budgets and investor timelines. If you need to move fast and build something fundable, that's our sweet spot.

We don't disappear at go-live. We offer ongoing support, bug fixes, and feature development on a retainer or project basis. Most clients continue working with us after launch.

Yes — always, and before any discussion of your product details.

Yes. We've taken over legacy systems, modernised them, and scaled them. If you have existing code, we'll audit it honestly before committing to anything.

Our founders are based in Dhaka (UTC+6) and work with clients in the UK, US, Canada, and the Middle East. We're comfortable with async collaboration and scheduled calls across time zones.
