More about Taavi Tammiste

My passion is finding actionable value from data using applied machine learning. I have been an entrepreneur and C-Level manager for the last 3 years, connecting deep technical knowledge with business requirements. My main areas of knowledge are machine learning and distributed computing mixed together with agile product development. 

In the past, I have partnered with other C-level executives as well as innovation departments and entrepreneurs to help companies empower their data. 

In addition, I have spent time working as the Head of Data Science for one of the leading agile software development companies in Estonia and am now the co-founder of one of the most cutting edge computer vision AI companies in Estonia. I was nominated for the Young Entrepreneur of the Year award in 2019.

The eChai Effect - In Their Words

"eChai has played a truly pivotal role in HummingBird’s journey — even before Day Zero. From ideation to establishment and into growth, it’s been a constant source of support. It connected me with incredible people who’ve become more than just friends. One of the biggest reasons I chose to stay in Ahmedabad is because of the eChai community. It has shaped my growth — both personally and professionally — in ways that are hard to articulate. Honestly, words fall short when I try to express what eChai means to me. I’m deeply thankful and forever grateful to eChai for being such an integral part of my journey."

“eChai has been that turning point in my journey. It gave me a platform when I wasn’t looking for visibility but needed direction. Over the years, it became more than just a network. It became my tribe; a place where conversations sparked collaborations, and strangers became trusted sounding boards. What I value most is how effortlessly eChai brings people together - no airs, no filters, just genuine people with shared dreams. I owe a lot to this community and to Jatin, whose consistency and belief in people have shaped journeys like mine. Forever grateful to be part of something so real.”

“You don’t plan to build a company via eChai. You just keep showing up … and one day, you realize you did.” I’ve known Jatin since 2012, when I was still deciding what kind of second innings I wanted to play as an entrepreneur. Over the years, through events, chai breaks, intros, and seemingly small conversations, eChai helped shape not just Upsquare but also refined the lens through which we see collaboration. At Upsquare, we’ve hired talent, met partners, discovered co-investors, and built lifelong friendships. One of our joint ventures exists today only because a casual eChai memory sparked a deeper trust. Now, as we build House of Starts — our venture builder — eChai continues to fuel our mission: co-creating a shared future. eChai isn’t just a startup network. It’s a trust network. And for business builders like me, that makes all the difference."
