We are a UK-based, founder-led studio that ships startup MVPs in 21 days — with fixed prices, 100% source code ownership, and no AI-product-builder middle layer between you and the people building your software. If Builder.ai felt opaque, this page is for you.
Six concrete differences founders mention when they explain why they chose us over a Builder.ai-style platform.
You speak directly to the person building your product. Bela Gulyas, founder of GuruSoftwares (BELAVIN LIMITED, Companies House 16735157), works with every client. No tier-1 account managers, no offshore handoffs.
We agree a single fixed price after a free scoping call. No monthly retainers, no “package upgrade” surprises, no platform fees baked into the price.
Your code lives in your private Git repository, with full documentation. Switch to any team you want post-launch. No platform lock-in.
Focused web MVPs ship in 21 days. Mobile and SaaS MVPs in 4-8 weeks. We are honest about which scope fits which timeline.
Flutter for mobile, Next.js / React for web, Node.js + PostgreSQL for backend. Standard, hireable, debuggable tech — not a proprietary builder you cannot leave.
BELAVIN LIMITED, registered in England & Wales (Companies House 16735157). UK GDPR by default, ICO-aware data handling, and a real privacy policy.
We respect Builder.ai — it solves a real problem for some founders. Here is where each approach makes sense.
You want a SaaS-style platform with a self-service feel, your project fits well-trodden patterns, and you are comfortable with platform-driven delivery. Their library of pre-built features can shorten certain builds.
You want direct contact with the developer building your product, your scope has UK-specific or industry-specific nuance (fintech, proptech, healthtech), or you want to retain full ownership and avoid platform lock-in.
We are a focused studio, not a managed service with hundreds of staff. We take on a small number of clients at a time. If you need 50 engineers in the next 30 days for a complex enterprise build, we are not the right fit. For most startups and SMBs, we are.
Tell us what you’re building and what is making you reconsider Builder.ai. We’ll come back within 24 hours with an honest scope, a fixed-price quote, and a recommendation — even if that recommendation is to stay with Builder.ai.
