Oura

OURA is doing something weirdly specific in a market dominated by wristbands — they're a ring, which sounds like a gimmick until you remember they've actually shipped millions of units and built a serious sleep-tracking moat. They're going head-to-head with WHOOP in the human performance wearable space, but here's the thing: Oura plays the long game with recovery data while Whoop flexes on strain metrics — same player, totally different game. The signal is that they've cracked the health hobbyist market in a way few hardware companies manage, and that's worth watching.
