From zero to validation. In weeks.
We build production-ready software MVPs for early-stage tech startups fixed scope, no equity, no long-term contracts.
Fixed scope. No long-term contracts. Full code ownership.
If your idea has critical flaws, we tell you during the evaluation call before you commit.
If you have an idea, we turn it into a real MVP.
You bring the idea. We define the minimum testable product, build it, deploy it, and hand over ownership.
Define
Identify core assumptions and map what needs validation.
Reduce
Strip scope to one testable feature. Cut everything else.
Build
Deliver production-ready software in 6–8 weeks.
Deploy & transfer
Ship to production. Transfer repo, docs, and ownership.
Built by senior engineers. Delivered directly to you.
No sales layer, no hand-offs, no junior teams. Direct collaboration with experienced builders.
Not an agency
You work directly with the senior engineers building your MVP.
No hand-offs
Senior-level execution from start to finish. No delegation.
No juniors
Experienced technical leadership on architecture, code, and deployment.
Fixed scope
Defined deliverables before we start. No feature creep.
Ownership guaranteed
Full repo access, complete documentation, zero lock-in.
Who it's for
Early-stage teams ready to validate with real software.
If you're looking for mentoring or incubation, this is not for you.
We work exclusively on digital products, web apps, mobile apps, SaaS platforms.
Real situations we work on
Common early-stage scenarios where a lean MVP makes sense.
Non-technical founder with validated demand
Need a real MVP to start acquiring first paying users
Startup preparing enterprise or investor demo
Need production-ready software to showcase capability
Company exploring AI/ML feasibility
Need proof-of-concept before hiring a full-time CTO
Team stuck between idea and execution
Need fixed-scope delivery to move from concept to validation
How it works
Three clear steps from evaluation to delivery.
Evaluation call
We assess feasibility, scope, and risks. No fluff.
Fixed scope & price
No surprises. No scope creep. Clear deliverables.
Build & delivery
6–8 weeks. Weekly updates. Full handoff at the end.
Founder feedback from early-stage collaborations
“Scope locked in before we started. No creep, no upsells. We knew exactly what we'd get and when.”
Giulia C.
“Deployed to production in 7 weeks. Full repo handoff with Docker configs, environment setup, and API docs. Our new engineer onboarded in two days.”
Edoardo D.
“They told us what NOT to build. Honest risk assessment during evaluation saved us months of wasted effort.”
Francesco B.
“Handoff was clean: Git repo, deployment scripts, monitoring setup. Everything we needed to own and extend it.”
Andrea A.
What you get

Raise funds or onboard partners
Use the MVP to demonstrate capability and secure resources
Full ownership. Full independence. No ongoing obligations.
From idea to validation
Most founders start at Step 1, then decide whether to build.
Fixed scope. Fixed price. No surprises. Building software below €4k typically means cutting scope, quality, or both.
Step 1 - Idea & MVP Check
Understand what to build, what to cut, and whether to proceed.
Deliverables
- —MVP scope (in/out)
- —User flows + lean backlog
- —Stack/architecture recommendation
- —Realistic build estimate
- —Handoff call + shared doc
Step 2 - MVP Light
Ship one core feature to test with real users or show investors.
Deliverables
- —Working web MVP (single core feature)
- —Essential DB + API
