Ask Shomik

What parts of AI feel underexplored right now?

Even with the hype, most areas are still early. New model architectures beyond transformers, autonomous security agents, and AI-driven infrastructure that replaces rules and tagging systems are all wide open.

What does a “frontier AI founder” look like today?

Frontier founders usually start with a vision that feels unrealistic at first, then clearly map the technical steps to get there. They’re pushing the edge of what exists today—whether in models, chips, or robotics—to accelerate a future that otherwise would take much longer.

What are founders getting wrong about building in the AI era?

AI will reinvent a lot, but many fundamentals still matter. Great sales, strong hiring, and customer value still win—the difference now is teams that combine human judgment with AI will outperform those relying on either alone.

How should founders and investors think about TAM (total addressable market)?

It’s not just the TAM you enter with, but the TAM you exit with that matters. Successful enterprise companies often start in a niche, then expand into adjacent markets through execution and deeper customer penetration, not by chasing a large TAM from day one.
