Both agencies are in Amsterdam — does location matter?

For most projects, no. We work remote-first. Location only matters if you need regular in-person workshops. Both agencies can accommodate Amsterdam-based meetings, but neither requires them.

I have not fully defined my product yet. Should I go with the agency that offers more strategy?

It depends on how undefined. If you have a rough idea of the core workflow and who your user is, we can scope it. If you are still validating whether the problem is worth solving, a strategy-first engagement may save you from building the wrong thing. We are happy to have an honest 20-minute call and tell you which camp you fall into.

Why does ISPIRLI not list hourly rates?

Because we do not bill hourly. Every project is scoped and priced before we start. We have found that hourly billing creates misaligned incentives — the agency benefits from taking longer. Fixed price means we are on the same side.

Side-by-side comparison

ISPIRLI vs Zedrox.

Both are Amsterdam-based agencies that build software products. Here is how they differ.

Feature comparison.

Feature	ISPIRLI	Zedrox
Pricing model	Fixed price from €12,500	Undisclosed hourly
Starting timeline	<2 weeks	4–6 weeks typical

Fixed-price guarantee	Yes — all projects	No
Post-launch ownership	Full code + repo handover	Variable
Direct engineer access	Yes	Through project lead
Shopify capability	Yes	No
SEO services	Yes	No

Where ISPIRLI wins

Fixed price eliminates budget risk
Faster start — 2 weeks vs 4–6
Own SaaS products prove real-world capability
Full-stack — SaaS + Shopify + SEO
Direct access to building engineers

Where Zedrox wins

Deeper upfront product strategy consultation
Stronger UX/design capability on complex products

Bottom line.

If you need a deep discovery and product strategy engagement before writing a line of code, Zedrox is a reasonable choice. If you have a clear idea and want it built on a fixed price with direct engineer access from week one, ISPIRLI is the better fit.

“Most founders come to us after initial conversations with consulting-led agencies where the discovery phase alone cost €3,000–5,000 before any code was written. We scope quickly, price firmly, and start building.”
