Co-founder of Optimizely and Obama's 2008 director of analytics, Siroker turned Rewind into Limitless and shipped the $99 Limitless Pendant, an always-on wearable that records, transcribes and recalls conversations — the product that made the always-listening category real enough to argue about. Meta acquired Limitless in December 2025 on undisclosed terms; hardware sales stopped, existing customers were promised a year of support, and the team went into Meta's device effort. The pendant's real legacy is the consent question it forced: what happens when the person wearing the microphone is the only one who agreed.
