Startup Club #4: Bootstrapped to $25M ARR: How Astra AI went from free math videos to a million users
Three years ago, Astra AI was a free math explainer site. Today, it is past $25M ARR with more than a million users, a small team, no office and zero investors.
At our next Startup Club, Klemen Selakovic, CEO of Astra AI, joins us for a fireside chat led by Tomislav Nikočević. Klemen will walk us through how AI collapsed the timeline from idea to scale, what building a bootstrapped AI company allowed the team to do differently, and why he would choose to stay unfunded again.
The conversation will also look at what this new playbook means for founders and investors in the region: how much can a small team now build, which parts of scaling have fundamentally changed, and where outside capital still makes sense.
We will start with a short fireside chat, with Tomislav guiding the conversation, and then open the floor for audience Q&A.
