Development company from Poland | Est. 2012

The senior team behind your AI and SaaS product

We build new products and take over existing ones. Every engineer on your product is senior. AI coding agents do the repetitive work, and a senior reviews every change before it merges.

__> Teams we have built for

In short

Clients usually call us when the deadline is real and the team is thin. nini.bot went from intent to an installable PWA in 11 days. Teamdeck moved its staging to Temporal, Pulumi and ECS in about nine weeks while product work kept shipping. Our voice agents handle 1.5M+ calls a month. And the people who built it stay on after launch.

How we work

01Who works on your product

Senior engineers only, and they stay

We don't put juniors on client projects. The 30+ engineers on our delivery team plan their own work, raise risks early and ship without daily direction. Average core-team tenure is 6.5 years, so the people who learn your codebase are usually still here next year.

02How the work gets done

AI agents write the routine code. Seniors decide what merges.

Our engineers work with an AI coding harness they configure themselves. Every change starts as a written plan, passes CI gates and gets a senior review before it merges. On nini.bot that took us from intent to an installable PWA in 11 days.

03Where we start

Your budget goes on the product, not on login screens

Auth, tenancy, Stripe billing and an admin panel come from our open-source SaaS Boilerplate, which already runs in production. We use it in Teamdeck, our own resource planning SaaS. For AI features, PII handling, retention rules and audit logs go in during the first sprint.

04After launch

The team that built it keeps it moving

Two-week sprints, a backlog you can see and month-to-month terms. Add engineers when the roadmap grows and scale down when it shrinks. When legacy code is what slows you down, we modernize it while the roadmap keeps moving.

It was a pleasure working with the Apptension team. This is the second website overhaul we work on together and they did a great job, not to mention what a lovely bunch of people they are. They bring very good energy and predisposition to all meetings, turn things around quickly, they are very helpful when it comes to troubleshooting and seem to be able to do it all from a technical POV - I'm yet to find a challenge they can't solve.
