Our Story

Built from need.
Shared by choice.

Global Gamma didn't start as a company. It started as a frustration with tools that didn't meet the standard — and the conviction that we could do better.

The origin

We built what
we needed.

A decade spent building quantitative pricing engines, risk models and portfolio analytics at HSBC and leading global asset managers teaches you one thing clearly: the quality of your tools determines the quality of your work.

Off-the-shelf software rarely meets the standard. Not because it's built badly — but because it isn't built by people who have lived at the problem. We have. Every formula in our tools, every assumption in our models, was forged under real institutional pressure.

"The models we ran daily demanded precision that existing software simply could not provide. So we built our own — and we always had."

Global Gamma is the formalisation of that approach. We took the tools we'd built for ourselves, sharpened them, and made a decision: these should be available to everyone. Not as a simplified version. As the real thing.

Our Offers aren't designed for the market first. They're designed to solve real problems — the ones we lived with every day. The market comes second. That's the order of things here, and it's what makes the difference.

Why share it?

Because good tools shouldn't live behind institutional walls. If a quant model can help a freelancer make a better financial decision, it should. Access to precision doesn't have to be a privilege.

Why trust it?

Everything we ship has been stress-tested against the standard we held ourselves to at tier-one institutions. We don't ship guesses. We ship rigour.

Who is it for?

For anyone who has ever felt let down by a tool that should have been better. From individual freelancers to quant desks — the standard should be the same.


The Founder

The person behind the platform.

Global Gamma
Youssouf Kerzika
Founder · Quantitative Researcher

Over a decade in quantitative finance — building XVA pricing engines, running credit and funding risk models, and designing portfolio analytics systems at HSBC and leading global asset managers.

Specialising in XVA — CVA, DVA, FVA, MVA, and KVA — Youssouf has spent years at the precise intersection where rigorous mathematics meets the pressure of real markets. The models had to be right. The software had to match.

Global Gamma is the answer to a simple observation: the best tools were always the ones we built ourselves. It was time to make them available beyond the institution.

What we stand for

Six principles we don't compromise on.

01

Rigour first

Every model, assumption and calculation is held to institutional standards. We don't ship approximations when precision is achievable.

02

Honest maths

We document what we build. If there's an assumption in our model, you'll know about it. Transparency is not optional.

03

Access without compromise

Institutional-grade doesn't mean institutional-priced. The quality of our free tools matches our paid ones.

04

Built, not bolted

AI and advanced analytics are built into our architecture — not added as afterthoughts to justify a higher price tag.

05

Users over metrics

We build tools that genuinely help. No engagement loops. No dark patterns. We want our tools to make a real difference.

06

Staying small on purpose

We'd rather grow slowly and get everything right — just like the models we run. Quality over velocity, always.
