We buildSaaS & platforms

We develop new products and take on clearly defined workstreams in existing platforms - senior-led and hands-on, with ownership from scope to production.

How we start →

With DEVBLD. we build products from scratch or step in where an existing team needs support. We work hands-on, think long-term and design technology so it doesn't just ship, but keeps evolving cleanly.

The same 16 weeks,two paths.

Recruiting, notice period, onboarding: it often takes months before a new hire really ships.

Illustrative timeline. How long a senior hire takes varies a lot - the workstream doesn't have to wait for it.

The role can wait.The workstream can't.

The open role is rarely the real problem. What matters is what sits still until it's filled.

Start small.

Instead of pushing it back again: five days of clarity first, then you decide. If you continue: fixed price and a 30-day release target, confirmed after clarification.

Roadmap Unblock

Five days of technical clarification. €3,000.

After day 5 you can stop. It stays at €3,000, and the solution path, scope and code are yours.

  • Fixed price. No timesheets. It only costs more if you extend the scope.

  • Delivery commitment. If the confirmed date slips because of us, we finish at no extra fee.

If you continue, the whole workstream costs €18,000 net. The €3,000 is already included.

So what's the catch?

Review: external engineering

1/8 resolved

  1. Nils · DEVBLD

    External doesn't have to mean short-term. Our longest client relationships have been running for years - with fixed contacts and plannable availability.
