Igor Taber has sat on both sides of the table: first as a VC at Intel Capital, then as an operator at high-growth AI startup DataRobot. Now, as co-founder of Cortical Ventures, he’s backing the next generation of AI-first startups.
In this episode, Igor shares how his operating experience reshaped his investment lens, what most VCs still miss about early-stage execution, and how founders can break through the AI noise to build something that actually lasts.
We also get into:
- What it really takes to build conviction at the seed stage
- How Cortical Ventures defines “defensibility” in AI
- The questions every founder should ask an investor (but usually doesn’t)
- Why your biggest advantage may not be your model — it’s your momentum
