Client retention
Words from the teams we ship with.
★★★★★
"XZ Code rebuilt our entire checkout and we hit 184% lift in conversion within six weeks. The team operates like an extension of ours — sharp, fast, opinionated."
Maya Okafor
VP Product, Northwind
★★★★★
"Rarer than their craft is their judgment. They pushed back on the brief in the best way, and the product is meaningfully better for it."
Julian Reiss
Founder, Helix
★★★★★
"A real partner. The design system they delivered is still the foundation of every product we ship two years later."
Aiko Tanaka
Design Director, Prism
(07) — FAQ
Common questions, honest answers.
Still curious? Drop us a line and we'll respond within a working day.
How much does a typical project cost?
Most engagements fall between $40k and $250k depending on scope, complexity and
timeline. We'll always quote a fixed price after discovery.
How long does a project take?
A focused MVP typically lands in 8–12 weeks. Larger platforms run 4–9 months in
phased releases.
Do you work with early-stage startups?
Yes. We love pre-seed and seed teams. We can also offer equity-flexible structures
for the right partners.
What happens after launch?
We offer retainer-based care, growth experimentation and on-call engineering. Most
clients keep us close for 6–12 months post-launch.
Where is the team based?
We're a distributed studio across 8 timezones. Async-first, with overlap windows
for real-time collaboration.
