I'm Elad Nahum — a technical founder who spent 17 years managing real portfolios and a decade shipping production software. I put both to work building Guardfolio: institutional-grade portfolio risk, made usable for everyday investors. Here I write about markets, risk, AI, and what it actually takes to build financial software that works.
I started as a financial advisor at Bank Hapoalim. Real money, real clients, real consequences. Five years of that teaches you things no MBA class covers — how people actually behave with risk, what stress-testing a portfolio feels like at 2am, why most "safe" plans aren't.
Then I got the MBA anyway. Strategy and Entrepreneurship. And somewhere in there I started teaching myself to code — not as a career pivot, just because I kept having product ideas and couldn't build them.
That turned into a decade of programming. Four of those years at CHEQ, a global ad-tech company, shipping full-stack features used by enterprise clients worldwide — Vue.js frontends, Golang microservices, everything in between.
Now I lead product strategy and financial methodology at Guardfolio, the company I founded to bring institutional-grade risk tools to individual investors. Two careers. One problem worth solving.
From zero to production — products I've founded or led engineering on.
AI-powered portfolio protection and risk management for retail investors. Built from first principles — product strategy, architecture, and full-stack engineering all in-house. Solving a problem I lived for 17 years: institutional-grade risk visibility was never available to individual investors. Until now.
Full-stack engineering on the product-led growth team at a global ad-tech company. Architected and shipped features used by enterprise clients worldwide — Vue.js frontends, Golang microservices, and everything in between. Turned product strategy into measurable revenue.
Started my career advising clients on portfolio allocation across equities, bonds, and structured products. Real money, real consequences — the foundation that informs every product decision I make today.
Everything I learned managing portfolios for 17 years, built into software. Guardfolio connects your stocks, crypto, and ETFs, scores your real risk, and alerts you before something breaks — the kind of monitoring desk that used to be reserved for institutions.
One number that captures your portfolio's real risk, updated as markets move.
Plain-language warnings before market, position, or event risk turns into a loss.
Every account — stocks, crypto, and ETFs — in one risk-aware view.
Concentration, correlation, and exposure analysis that used to need a terminal.
Essays on portfolio risk, markets, AI, and what it actually takes to build at the intersection of finance and software.
AI stocks are powering market gains, but ETF overlap, Nvidia concentration, high valuations, and leverage can leave portfolios less diversified than they appear.
Different ETF labels can still point to the same underlying stocks, creating hidden concentration risk in AI-heavy portfolios.
Most portfolios are far less diversified than their owners think. Here's what concentration risk really looks like, and why it's so easy to miss.
Volatility is not the enemy. Mismanaging it is. Here are the strategies that actually work when markets get choppy.
Every founder is talking about AI. Very few are thinking clearly about what it actually shifts in the product, the moat, and the business model.
A founder's honest account of the problem, the market gap, and what it's like to build a FinTech startup when you've spent 17 years on the other side of the trade.
The domains I write, build, and think in — at the edge of markets, software, and what makes businesses actually work.
Right now: Building Guardfolio, writing about markets and risk, exploring AI in portfolio management.
Whether you're working on something interesting, want to explore a partnership, or just want to talk markets and building — I'm open to conversations that go somewhere.
