Senior software studio · Fixed prices
We rescue AI-built apps, ship production AI features in 10 days and make GPU inference faster and cheaper. Fixed prices, code in your repository from day one, and you can start this week.
Range
A studio since 2016, and twenty years in the industry. From GPU kernels to Stripe webhooks, there are very few layers of the stack we haven't shipped. If it runs on a computer, we can build it, fix it or make it faster.

How we work
01
Scope is written down before we start. If it changes, you see the new price before anything moves.
02
Nothing is locked to us. You own the code on payment and can walk away with everything at any time.
03
You see working software on your own data every few days, so there are no surprises at the end.
04
The people on your kickoff call are the people writing your code. No juniors learning on your budget.
No discovery phase that costs more than the work. The scope gets written down on the first call and the clock starts.
Today
Pay for a fixed offer, or book a 30-minute call for anything custom.
Next business day
Kickoff call. Access granted, scope written down, demo dates set.
Every few days
Working demos on your data, plus a short written update.
Delivery
Handoff in your repo, docs and a walkthrough. Support window starts.

Senior engineers, and only senior engineers. We present our work as coderband, the studio, and you meet the engineers on your project at the kickoff call.
coderband LLC is a US company registered in Wyoming. The team works on Central European Time, which covers the full European day and overlaps US mornings.
You do, once it's paid for. The work lives in your repository from the first commit. Pre-existing tools and open-source libraries are licensed to you, so nothing ever blocks you from running or changing your software.
Every fixed offer has a written guarantee: a full refund on the audits if we don't deliver what we promised, a refunded deposit if the day-5 sprint demo doesn't convince you, and a refunded first month on retainers. The details are on each offer page and in our terms.
Yes. Confidentiality is part of our standard terms, we're happy to sign your NDA, and we sign a GDPR data processing agreement whenever we touch personal data.
By card through Stripe for the fixed offers, or by invoice and bank transfer for larger engagements. Prices are in USD.
Branding, marketing and SEO services, and low-cost hourly staffing. We take on engineering problems, and we price for senior people.
