If you are thinking about working for WHOOP, I urge you to read this first:
WHOOP is plagued by a pompous, micromanaging, inexperienced CEO who has literally never worked anywhere else but his own company. Will is single-handedly running WHOOP into the ground and it's shocking the board hasn't asked him to step down yet. Instead, they have silently removed almost every other c-level executive including the CTO, CMO and CPO in less than 6 months.
It's also important to remember that WHOOP really only "blew up" during the early stages of the pandemic when word got out it could predict COVID based on respiratory rate data. With demand surging, the company got a big round of funding then went on a massive hiring spree and spent millions of dollars on thoughtless and unnecessary marketing activity (i.e. a massive sign over Fenway park) in order to "growtain" -- the only metric the CEO goals the company against. They then went on to completely botch the WHOOP 4.0 launch and unveil the device fully knowing that there was no product supply in stock and that they'd never be able to fulfill orders. This led to the company essentially unable to acquire any new members for 6+ months, leading to its demise and current state.
Culturally, WHOOP operates like it's still an early stage startup with 50 people, versus a company with 500+ employees. It has a mostly non existent HR team, a bro-like culture riddled with favoritism and a bunch of young, egomaniac employees. Despite preaching "transparency" as a key corporate value, there is very little of it. Weekly all-hands meetings are held only to celebrate and highlight good work with little to no acknowledgement of any hardship or challenges.
Lastly, the pay here is far below industry standard and benefits are very average for the tech industry. They sell you on the promise of equity (which they generously grant), but based on my experience, there is zero chance they'll ever make it to an IPO with the current leadership in place.
