“It can’t be done. Too many have tried and failed.” “Dead on arrival. I haven’t used one in decades.” “You’re starting a what?” “Are there even a hundred people who have a ‘concentrated portfolio’?” This is what I heard from the largest wealth managers and RIAs in the country when I first floated the idea of building a modern exchange fund. In 2022, I realized that many Americans were becoming more concentrated, driven by the growing trend of stock-based compensation and a historic bull-market run. Yet tax-efficient investing was limited to a small set of clients. I saw this as a massive opportunity. For decades, exchange funds had been a duopoly. And like most markets without competition, progress had slowed. It felt like a product from the 80s that hadn’t even met the internet. Minimums, fees, and the barriers were high. We believed that it didn’t have to be true. So we set out to build what many said couldn't be done: a modern exchange fund that was transparent, accessible, and efficient. Just twenty months after launch, the market has spoken. Cache recently crossed $1B in assets, likely one of the fastest to reach this milestone among digital investment platforms. But this milestone isn’t about speed. It’s about a shift in who gets access to tax-efficient investing. The walls have been broken. This category no longer feels like a closed room with a velvet rope. In 2025 alone, we grew approximately 4×. Our flagship exchange funds delivered performance in line with our goals. For example, UNIX achieved a ~0.99 correlation through our Index Sync approach. We're grateful to the clients who trusted us early—and to the incredibly talented team that brought this vision to life. Here’s to 2026, and here’s to building what the experts said cannot be done! #wealthmanagement #personalfinance #financialplanning #concentratedstock





















99% correlation. Tight alignment with the benchmarks. Here’s how we rebuilt the exchange fund from the ground up. Just a year ago, we launched our flagship exchange fund, UNIX, benchmarked to the Nasdaq‑100. Last month, we added Bedrock, benchmarked to the S&P 500. Both funds have now achieved tight alignment with their benchmark — while continuing to onboard bi‑weekly. Historically, that was one of the challenges associated with exchange funds. Capacity was unpredictable. Tracking error was a concern. And most investors were not certain what they’d own at the end of the 7‑year hold. We have rebuilt the model. Index Sync lets us dynamically align to the Nasdaq‑100 or S&P 500 using ETFs to rebalance and prevent drift. It also lets us say “yes” to more of the stocks people actually hold. The results (as of July 31st, 2025): ✅ UNIX (Nasdaq‑100): 0.99 realized correlation, with a beta of 1.06 indicating close alignment. ✅ Bedrock (S&P 500): Exposure to 700+ stocks, spread out across all major market sectors. It’s proof that an exchange fund can be both tax‑efficient and benchmark‑precise.
