In their words

What clients say after handover

We ask for these six months after the final invoice, when the honeymoon is over and the app is somebody else's responsibility.

Tobias Lindqvist
The handover pack was the part that surprised me. Our two in-house engineers picked up the codebase in a week and have shipped four releases since without calling anyone.
Tobias Lindqvist CTO, Nordbyte Logistics
Amara Sethi
They cut a third of our feature list in the scoping week and were right about all of it. That one conversation saved more money than the whole engagement cost.
Amara Sethi VP Product, Larkfield
Dr. Helena Marsh
Our compliance team is famously difficult. Nimblestack turned up to the review with the audit trail already written. First submission, no findings.
Dr. Helena Marsh Clinical Director, Vesper Health
Joel Amankwah
Every second Thursday there was a build on my phone. After eleven years of agency slides, that alone was worth the rate.
Joel Amankwah Founder, Halden
