A senior software team that builds booking systems you own

Timerise is a senior software team. From 2021 to 2025 we ran our own booking platform, used by a consulate, a luxury brand and marketplaces. Since 2026 we build custom booking systems: one fixed price, code and data the client owns, no subscription and no commission.

The story

Where does Timerise come from?

From 2021 to 2025 we ran our own booking platform. At the start of 2026 we began building systems that each client owns.

Before

  1. 2021

    We launched a booking platform

    Booking pages, an admin panel and an API that businesses used every day.

  2. 2022 to 2025

    Years in production

    Running it showed us where booking systems break and that the same parts come back everywhere: booking rules, calendar sync, payments, a kiosk, screens in the venue, invoicing. It also showed us what a rented system can't give a business: its own code.

2026

This year we went through an AI transformation

AI took over the repetitive code, so engineers spend their time on the logic that makes a business its own. The past is behind us.

After

  1. Since 2026

    A studio, not a platform

    We wrote each part down as an open Agent Skill and build every new system from those parts on the client's own stack.

  2. Every project

    Delivered in weeks, owned by the client

    Our team hands over the code and the data, and stays for three years of support.

What we believe

What are we not willing to compromise on?

Six principles, written down in full in the Post-SaaS manifesto.

Own what is core

If booking drives your revenue, you should own the code, the data and the logic behind it. We build systems and hand them over. We never keep a key.

Owning is not operating

Owning a system never means running a server you do not want to. We set it up in your cloud and can keep it healthy for as long as you like, or hand it to your own team.

Growth must not raise the bill

No commission on bookings, no per-seat fees, no revenue share. Hosting costs track usage, not your success.

Workflows shape the system

Your rules are the specification. We model conditional availability, shared resources and local pricing instead of asking you to fit a template.

Leaving stays cheap

Common technology, full documentation, and the code in your own account. Any good developer can pick it up after us, and that is the point.

AI ended the trade-off

Custom used to mean slow and expensive. AI now writes the repetitive code, so engineers spend their time on the logic that makes your business yours.

The team

Who will you work with?

The two founders lead every project: Piotr on the product, its scope and how it feels to use, Matt on the backend and the infrastructure it runs on. You talk to them from the first brief to the handover, together with the senior engineers who build the modules.

How we work

What is it like to build with us?

You talk to engineers

The people who answer your questions are the people who build your system. There are no account managers in between.

A few projects at a time

We take on a small number of builds at once so every project has senior attention from the brief to the handover.

Public building blocks

The modules we ship most often are published as open-source Agent Skills. You can read what we build from before you hire us.

AI accelerates, engineers decide

AI generates the repetitive parts and drafts the prototype you see within 48 hours. Architecture, business logic and review stay with people.

The full process, phase by phase, is on How we build. The building blocks are on Agent Skills.

Our clients

Where are our clients?

In 10 countries on 3 continents. We work remotely, in English and Polish, so distance is not a problem.

The company

Who signs the contract?

One legal entity signs every contract and every invoice, and it is the same one that builds the system.
