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.

01

Define

Identify core assumptions and map what needs validation.

02

Reduce

Strip scope to one testable feature. Cut everything else.

03

Build

Deliver production-ready software in 6–8 weeks.

04

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.

Non-technical founders
Pre-seed startups
Solo founders testing a real market
Teams preparing investor demos

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.

01

Evaluation call

We assess feasibility, scope, and risks. No fluff.

02

Fixed scope & price

No surprises. No scope creep. Clear deliverables.

03

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.

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

€490–€9905 days

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
Start with MVP Check

Step 2 - MVP Light

FAQ

Common questions about scope, ownership, and delivery.

Between €4,000 and €12,000 depending on scope. Most founders start with the €490-€990 MVP Check to define scope and get an exact estimate before committing.
4-8 weeks depending on complexity. Single-feature MVPs take 4-5 weeks. Multi-feature MVPs with integrations take 6-8 weeks.
Only the core feature needed to validate your assumption. Everything else is cut. We help you define this during the MVP Check phase.
No. We work with non-technical founders regularly. You get full code ownership and documentation so you can hire a team later or continue building internally.
No. You own 100% of your company and 100% of the code.
It doesn't. Scope is fixed before we start. Feature creep kills MVPs.
Yes. New scope, new quote. You can extend or take it internally.
We tell you during the evaluation call, before you commit any money.
Production-ready. Real users, real deployment, real code ownership.
No. We only build software, web apps, mobile apps, and SaaS platforms.
Yes. Full code ownership means you can hand it off to anyone.
