    Our Story

    We started Cosmos Thrace in 2019 with a simple belief: data consulting should feel like a partnership, not a transaction. Viktor Elevterov (Founder) and Ivan Angelinin (CTO) built a team of certified Databricks engineers who stick with clients long after go-live. Today we're a Databricks Silver Partner, co-led by Managing Partner Idan Harel, with a family-like team that goes the extra mile with an extra smile. Every client we've had is still with us - that says more than any credential.
