In this episode of This Week in Startups, hosts Jason Calacanis and Lon Harris interview Rahul Chhabra and Atmadip Banerjee, CEO and CTO of SABI, about their non‑invasive brain‑computer interface (BCI) packaged as a beanie. The hosts are highly skeptical, repeatedly calling the product a "cap" and demanding a demo. Rahul explains the technical lineage from functional MRI research to a cap with 70‑100 k biopotential sensors that can decode thoughts word‑by‑word, though current performance is limited to slow, deliberate speech. He shares his background in math, electronics, autonomous drones, early LSTM work, and EMG‑based fatigue detection, and notes that the company is based in Palo Alto and has attracted eight‑figure backing from Vinod Khosla. The conversation touches on privacy, data encryption, and the challenge of reading signals through the skull. The episode then shifts to community‑building tactics for the TWIST ecosystem. Jason outlines a "CEO‑of‑every‑domain" approach, appointing staff to own editorial, sales, community, etc., and introduces the Noti Gang chat groups as a way to engage the top 1 % of the audience. He emphasizes that ownership drives excellence and shares practical tips for nutrition, sleep, and socialization. Later, the hosts launch a $5 K bounty for developers to build a live AI sidebar that provides real‑time fact‑checking and a "cynic" persona during podcasts. They discuss technical stacks (Deepgram, Whisper, Gemini, ElevenLabs), evaluation criteria (ease of use, fit‑and‑finish, speed, output quality), and demo examples where the AI correctly fact‑checks political violence claims and offers snarky commentary. Multiple submissions are reviewed, with "Armchair" and "BMD Pat" highlighted as strong contenders. Finally, Jason announces a second contest to create an annotation browser extension (annotated.com) that lets users clip short audio/video (≤90 s) or text (≤100 words) under fair‑use rules, add commentary, and share via a social feed reminiscent of Delicious. The tool aims to foster community curation of news and media. The episode ends with sponsor reads and a reminder of upcoming bounty deadlines.
