FAQ
Common Questions
How much does it cost to work with Zulbera?
Engagements start at a €20,000 minimum. A typical project ranges from €25,000 to €500,000+ depending on scope, with most custom SaaS builds landing between €30,000 and €150,000. Pricing is fixed-scope per phase rather than hourly, so you know the cost before production begins.
How long does a build take?
After a 2–3 week paid discovery sprint, most builds run 10–24 weeks in sprint-based phases with weekly demos and a staging environment. A focused SaaS MVP can ship in roughly 10–14 weeks; larger enterprise platforms take longer. Timelines are agreed during discovery before any production commitment.
Who owns the code and IP?
You do. On handover the client owns 100% of the source code, infrastructure, and intellectual property, including repositories, documentation, and deployment configuration. There is no vendor lock-in and no licensing of the core product back to you.
What does the engagement model look like?
Four stages: a paid discovery sprint to lock architecture, scope, and team match; a build phase of 10–24 weeks with weekly demos, staging, and continuous deployment; launch and handover including load testing, a security audit, production cutover, and documentation; and an optional ongoing partnership retainer.
Who will I work with?
A senior-only team, founder-led. Every engineer assigned to your build is a senior practitioner: no junior developers billed at senior rates and no hand-offs to an unseen offshore bench. Zulbera has delivered 120+ projects at an aggregate 4.9 out of 5 across 20 verified reviews.
