Four Ninety Six backs the founders building the foundational layer of the next era of computing — the trust, security and infrastructure everything else depends on.
A perfect number is one whole, exactly equal to the sum of its parts. It appears at the precise point where a system either holds together — or breaks.
The sum of its own divisors. Perfect numbers are rare — we'd rather hold a few whole things than many fractional ones.
The exact value that lets superstring theory hold together as a coherent picture of the universe. Not a bigger theory — the missing term that makes everything fall into place.
The breakthrough is never the loudest wave — it's the technology that becomes the standard, the protocol the next era gets built on top of. That's our work: backing founders building the foundational layers of the next era of computing.
The trust, security and infrastructure everything else depends on. We back the products that catch fire because they're necessary — the inevitable ones — and we stay with them from the first line of code to the commercial breakout.
A flaw that breaks the whole system if no one resolves it. The largest unresolved anomaly today is the collision between AI and trust.
The governance, security and identity machinery that lets powerful models be adopted safely — closing the gap between AI speed and systems built for a world that no longer exists.
The load-bearing rails beneath finance — where complexity hides the points at which systems actually break down, and a single missing element determines everything.
Companies that change a field's underlying rules rather than competing within them — foundational shifts, not incremental ones.
The thesis made concrete. It intercepts sensitive data on the device and substitutes context-preserving stand-ins before anything reaches a model — so enterprises move at full AI speed without the flaw that was about to break them. The elegant resolution, not the heavier patch.
We'd rather hold a few whole things than many fractional ones.
Lead & co-invest at pre-seed and seed, where a single missing element still determines everything — and back select growth-stage companies where capital is the catalyst.
That's the part we back. Partner with us and you get builders who've sat in the founder's seat — early, direct, and built for the long climb to a category-defining company.
A builder before an investor, Shayra has started companies from nothing, raised the money, scaled them into the market, and taken one all the way public. She bets on founders the rest of the market underestimates.
Over a career building the load-bearing systems behind finance, crypto and enterprise AI, Jason developed a sharp instinct for where complex systems actually break down. He carries the firm's technical judgment.
