Ways to work with us
We don't bill by the hour. Scope and price are agreed up front, based on what you need.
One-off
Fixed-price project
A good fit when you know what you need. Otherwise, we start with an audit and a written plan, then agree on scope, a fixed price and delivery.
- Scope and deadline agreed in writing, one price
- Regular demos during the build
- A month of support after launch
Ongoing
Monthly partnership
We work through your priorities and show you finished changes regularly. You decide what comes first.
- Change priorities as you learn
- One engineer with AI tooling, no middlemen
- Pause or end the subscription any month
Common questions
Who owns the result?
You do. Repository, database and hosting are created under your name. Nothing stays with us as leverage.
Who do I talk to about details?
Directly with Andrej, who writes your software. No one in between.
What if you get sick or stop?
Everything is in your repository: code, docs and the reasoning behind decisions. The brief is written down and changes have tests, so any experienced developer can continue.
How do you use AI in development?
AI agents write the routine code under my supervision. I own architecture, security and review every change before it ships. That's how one person covers what used to take a team.
What if I end the partnership?
The software keeps running, because it's yours. You only pay hosting and any AI services directly to their providers. When you want to add something, get in touch.
How does first contact work?
You write through the form, we reply within one business day and set up a 15-minute call. No obligation, no preparation needed.
How long does it take?
An audit takes one to two weeks. An MVP 4 to 8 weeks. Bigger projects follow a written plan you get before we start.
How much does it cost?
We don't bill by the hour. An audit has a fixed price up front. Projects get a written quote after the audit. Monthly work is agreed per scope.
Can it be extended later?
Yes. Code, tests and docs live in your repository. Continue with us or with anyone else.

Building reliable systems and tooling for product teams.
SpexSol is a small studio by design. You talk directly to the person writing the code — no account managers, no hand-offs.
