Killion Labs: Simulate custom strategies across thousands of markets

Uncertainty about the financial future is one of the few things money doesn't fix. It doesn't care how much you earn or how successful you look on paper. The same question lingers: what happens next, and will I be okay? I kept noticing that people don't struggle with money because they lack discipline. They struggle because they can't see what their decisions actually lead to. And every generic tool I tried "helped" by assuming things for me: my risk tolerance, my expected returns, my retirement age. Someone else's defaults, presented as my future. So I built Killion: a simulation environment where you set the assumptions. Customize your risk tolerance, investment strategies, and returns across multiple asset classes, then test them on your actual holdings against thousands of market conditions. Two barriers shaped how it evolved. The first was data. Modern financial life is scattered across banks, retirement accounts, brokerages, and equity grants. You can't plan a life you can't see, so Killion connects all of it, read-only by design. The second was access. Serious long-term financial modeling used to mean expensive advisors or software most people couldn't justify. AI changed that math: analysis that used to cost a percentage of your assets can now be a flat monthly price. No AUM fees, no commissions, and your data is never for sale. The goal is simple: stop guessing, start knowing. I'd love your feedback. And if there's a scenario you've always wanted to test ("what if I retire at 50?" or "what if 2008 happens the year I retire?"), try it in the demo and tell me what you find.
