tl;dr: Castle launched out of stealth on august 13 2026: hedge the unhedgeable. frontrun flagged founder Lucas Cavalieri on may 20, 85 days before launch, when tracked investors started following him. the @castle_tech_ company account didn't hit our catalog until august 10, at 18 followers, 3 days before the reveal. by launch day, 13 tracked investors were on it.
what Castle does
a company today is an unintentional wrapper of macro events: an airline is an embedded oil trade, a solar developer is a tax-credit bet, a data center is a wager on permits clearing before a moratorium lands. these exposures are intangible, lack historical data, and sit unprotected on corporate balance sheets.
Castle covers them with markets and models: the risks insurers won't touch, so businesses can focus on execution. the team, ex quants, engineers, and hedge fund managers, has already traded alongside Susquehanna and Kalshi, covered as a CNBC exclusive.
the receipt: the founder moved 85 days before the company
founder flagged may 20, launched august 13. 85 days.

this is the person-before-the-company receipt. Lucas Cavalieri (ex quant at SIG, math at Stanford) hit our graph on may 20, when the first tracked investor followed him, while his account bio was the only public trace of what he was building. more tracked investors kept arriving through june and july.
the @castle_tech_ account itself didn't exist in our catalog until august 10, flagged at 18 followers, 3 days before launch. by launch morning the company had 13 tracked investors on it, with a follow surge landing the day of the announcement.
why the person beats the company
a launch receipt is not a fundraise receipt: our receipt ledger tracks rounds, and a launch is a different outcome from the same graph. but Castle shows the deeper pattern: investors follow the founder while the company has no name, no account, and no website. watch the person and you see the company months before it exists.
see the next one before it launches
Castle already shipped. the useful list is the founders tracked investors are converging on right now, before there is anything to see.
frontrun watches the follow graphs of 2,000+ tracked venture investors on X and flags the people and companies they converge on, with a date, the morning it happens.
