What others said no to
During Covid, every cybersecurity company was pitching a Ransomware Protection Guarantee that few VCs knew how to tell apart.
Why we backed it anyway
Ritesh and team approached the problem with the most disarmingly grounded perspective–that no one can guarantee complete ransomware protection, but they envisioned the best way to contain an attack.

What others said no to
AI eval was one of the most crowded categories of 2025, written off by nearly every investor as too crowded to bet on.
Why we backed it anyway
Nir Gazit and Gal Kleinman bet that the market didn't need another proprietary eval tool — it needed an open standard everyone could build on.

What others said no to
IoT Security had been written off by VCs for years as too fragmented to win.
Why we backed it anyway

The beliefs that drive our investments
01
The future of enterprise software is bespoke, not one-size-fits-all.
Bespoke systems are hard to build and secure without new infrastructure and security tooling.
02
The gap between simulation and reality is the next major infrastructure buildout.
Tooling for physical AI is decades behind traditional software engineering.
03
The biggest AI opportunities sit in regulated, historically non-technical industries.
These industries can't tolerate a full system rebuild and don't need one.
The FirstByte Difference
Problem-first
Our problem-first approach lets us go past the surface-level read that leads many investors to reject ideas by category alone — you work with an investor who's actually engaged with the problem.
Early-adopter network
The same problem-first mindset shapes our introductions. Rather than a static roster of advisor names, we connect you with people likely to become early adopters of what you're building.
Operating experience
Vidya has built and sold products before founding FirstByte — that experience makes her both a critic and a champion when you're deep in the trenches.
