Andrey Kozlov

I help fintech and wealthtech companies build technology that scales - without sacrificing engineering culture, quality, or retention. Over 18 years I've led engineering organisations from 6 to 30+ engineers, shipped mobile products to millions of users, and maintained 98% team retention across my career — a metric I'm particularly proud of in an industry known for churn. Currently CTO at 1FS Wealth — an award-winning AI-driven wealth intelligence platform (Innovation of the Year, Wealth & Asset Management Awards 2024; WealthTech of the Year, UK FinTech Awards 2023) serving family offices and HNWIs globally. I own technology strategy, engineering execution, and hold formal responsibility as Data Protection Owner under our ISO 27001 certification. What I do:→ Build and scale engineering teams with culture

at the centre (6→10 at 1FS, 30 engineers across

4 teams at Redpin)→ Deliver AI-native fintech products — 60%

efficiency gains at 1FS through pragmatic AI

implementation→ Lead technical due diligence and architecture

for fundraising and strategic partnerships

(Apex Group, US VC investors)→ Stay hands-on across Swift, Kotlin, TypeScript,

Python — while developing the managers around meWhere I've done it:→ 1FS Wealth (CTO) — ISO 27001 certified

wealthtech, AI implementation, Apex Group

partnership→ Redpin (Engineering Lead) — 30 engineers,

4 product teams, distributed systems at scale→ BCG (Mobile Architect) — global consulting,

~30 engineers→ Trainline, Betfair — mobile platforms serving

millionsWhat makes me different:I'm a technical leader who still codes, reviews architecture, and stays close to the work — but knows when to step back and empower teams. I believe the best engineering cultures are built on trust, transparency, and high standards, not micromanagement. Featured: The Diary of a CTO podcast, Jan 2026📍 London
