Fractional CTO for fintech, web3 & mobile

The technical co-founder you hire by the month.

Scaled a crypto exchange from $200k to $1bn a day. Built a Chromium browser from a two-person team to 6M users. Now I do it for you — fractionally.

The moat

Three things almost nobody else does.

100M+ LOC

Chromium & browser engineering

Maintaining a fork of a 100M+ line codebase with a small team — one of the rarest disciplines in engineering.

$XXXm AUM

Token deployment security

Contract deployment, key ceremonies, multi-sig and treasury custody strategy — cold-storage responsibility held for ~$XXXm at ZebPay. Trust is the product.

400k+ wallets

Web3 wallet engineering

Self-custody at consumer scale — passkey onboarding, proof-of-human, cross-chain UX.

Product philosophy
"If your mother can't use it, it's probably too complex."

In 2017, web3 believed "build it and they'll figure it out." They didn't — complexity is the adoption barrier, and UX has to do the heavy lifting. Product-minded before CPTO was a title: watch real users, not expert opinions; every wallet and every key ceremony above exists to serve people who will never read a whitepaper but know how to tap their credit card to pay for something.

How we work

Five ways an engagement starts.

LLM Training & AI Process Automation

Training your team to use LLMs to boost productivity as well as identifying processes that can be automated with AI assisted workflows

Scale & performance firefighting

Fix it, don't rebuild it.

Interim leadership

Holding the CTO seat — including hiring the permanent replacement.

Independent technical counsel

For PE firms, boards and family offices.

Token deployment security

Contract deployment, key ceremonies, custody strategy.

The arc

20 years building: F1 → e-health → $1bn/day exchange → 6M-user browser.

Sam Noble has spent 20+ years at the technical frontier — from McLaren's F1 decision platform to award-winning e-health, from the EOS mainnet launch to CTO of India's longest-running crypto exchange, to building a Chromium browser to 6M+ users. He operates through Ekawa Pte. Ltd. (Singapore) and works globally from Dubai, focused on Singapore, Hong Kong and the Gulf.

Mined Bitcoin in Norway in 2009. Lost the lot when the laptop was stolen at a company dinner. OG, in the most self-deprecating sense.
