A small studiowith senior hands.

Tacklebear is the studio of Konstantin Borimechkov, an engineer and founder from Sofia who builds software for businesses the same way he builds his own products.

Why Tacklebear exists

Before he wrote code for a living, Konstantin waited tables for two years. He saw how much of a working day goes to everything except the customer, and how rarely the software in the room helped.

Since then he has built systems used by more than a million people at Tide, shipped AI agents as founding engineer at a Y Combinator startup, and co-founded Menugram, a platform that now runs restaurants, bars and hotels across Bulgaria.

Tacklebear takes that experience to other businesses. That means senior engineering, honest scoping, and software judged by what it earns or saves.

How we work

Fast, without cutting corners
We ship in weeks what agencies quote in months, with clean, maintainable code you own.
Product-minded engineering
We have founded and run products ourselves, so we care about outcomes and conversion as much as code.
AI where it actually helps
From automations to LLM features, we use AI where it saves time and money.
