About

Two years old. A decade in practice.

Bartus IT was founded in 2023. The people behind it have been shipping software professionally since 2013 — and one of our longest engagements has been running since 2014.

What we are

An independent software firm,
based in Vilnius.

Bartus IT is a small, senior team. We build software for clients in ecommerce, fintech, healthtech and insurance — and we build our own product, ActionVox.ai.

We are not trying to be the biggest IT firm in the country. We are trying to be the one a serious team would actually choose for a serious project.

That shows up in how we staff (senior people only), how we engage (long-term, not project-by-project) and how we talk (specifically, not in superlatives).

Track record

The company is new.
The work is not.

Our founder has been writing code since 2005 and working as a professional software engineer since 2013. In 2014 he joined the founding team of ManoDaktaras — a Lithuanian healthtech platform — and is still part of it today.

Bartus IT was set up in 2023 to do that same kind of work — deep, long-running, founder-adjacent partnerships — for a wider set of clients. Between 2023 and 2025 we have grown into engagements across insurance (OPS International), automotive (Autogidas), real estate (Domoplius), ecommerce (Bookswap, Sena) and proptech (Strato Create), in addition to running ActionVox.ai in-house.

We are deliberately small, and intend to stay that way.

How we work

Five things we hold to.

  1. 01

    Senior or none.

    We do not pad teams with juniors to fill seats. Every engagement is staffed with people who have shipped real software for real users.

  2. 02

    Long-term over launch.

    Most of our engagements run for years, not sprints. We are interested in what a system looks like a decade in, not on its launch day.

  3. 03

    Honest scoping.

    If we cannot help, we say so. If a project should be smaller, we say so. Telling clients what they want to hear is bad for everyone.

  4. 04

    Stack follows the problem.

    We are not a "PHP shop" or a ".NET shop." Across the team we work fluently in PHP, .NET, JavaScript, TypeScript, Clojure, Erlang and the surrounding infrastructure. We use what fits.

  5. 05

    Ship reality, not slides.

    Working software beats decks. Our default deliverable is a thing in production that someone is using.

Leadership

Who runs it.
