What Investors Really Want From AI Founders

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
