The Story

I've been building financial data products since the dot-com era. In 2009, I left Google to co-found YCharts, where I served as CEO. YCharts is a financial terminal for investment professionals. We raised over $15 million from Morningstar, Reed Elsevier, and the Hyde Park Angels, and grew it to serve thousands of advisors in a $25 billion market before it was acquired by LLR Partners. The company continues to scale with over 100 employees today. That experience taught me what professional investors actually need: not more data, but timely awareness.

The problem I kept running into — as a builder and as an investor — was the same one everyone hits: you can't watch everything. You set a mental note to check a stock at a certain price, and by the time you remember, the move already happened. I wanted a platform that would watch the markets for me so I didn't have to stay glued to my screens.

In 2019, two engineers from Meta, Microsoft, and Amazon — Morgan Howell and Yahia Bakour — built exactly that. Stock Alarm solved the “last mile problem” for investors: push notifications, emails, texts, and even phone calls when your alerts trigger. It earned a 4.8-star rating from 7,000+ reviews because it did one thing really well.

In 2023, through my firm Center Mark Capital, I acquired Stock Alarm with 180,000+ users. Since then, we've grown to 295,000+ investors and expanded the platform from a pure alerting tool into a full research terminal — with screening, AI analysis, heatmaps, power rankings, macro dashboards, and institutional-grade research on 3,600+ stocks. All built on the same foundation: the markets watch themselves, and you get told when something matters.

After building WallStreetView, WallStreetSelect, YCharts, and now Stock Alarm, I've spent over 15 years on the same question: how do you give individual investors the same awareness that professionals have? Stock Alarm is the best answer I've found.

What We Believe

Alerts are better than screens.

Sitting in front of charts all day doesn't make you a better investor. Knowing exactly when something changes does.

Tools should support decisions, not make them.

We're a research platform, not a signal service. Our job is to tell you when to look deeper — not what to think.

Individual investors deserve professional tools.

The same screening, analysis, and awareness that institutional desks have — without the Bloomberg terminal price tag.

Signal over noise. Always.

We'd rather send you one alert that matters than a hundred that don't.
