100,000 free paid plans. That is how Brett Adcock is launching Hark this week. The founder @adcock_brett announced on X: the first 100,000 sign-ups get the paid plan free. Not free for a while. A hard cap. That turns a launch announcement into a race, and everyone who misses the cap becomes the next wave of demand. The product backs the pitch. Hark Handoff scores 97.7 on the Online-Mind2Web web-agent benchmark, ahead of GPT 5.4 at 92.8 and Claude Opus 4.8 at 84.1. $700M raised at a $6B valuation, and the whole launch is one post with a number in it. Steal this: if your launch offer has no cap and no deadline, it is not an offer. It is a pricing page.
