## Notes
- Cognition announced it was acquiring The Interaction Company of California, maker of the texting AI agent Poke, on 2026-07-23; Lohmann was a Member of Technical Staff at Interaction. (https://cognition.com/blog/interaction)
- Verbatim reply to Cognition's announcement that it had raised over $2B at a $48B valuation: "@cognition lfg 🚀🚀". This is his first public post addressed to Cognition as an employee. (https://x.com/maxiloh1/status/2097406058239021485)
- TechCrunch reported the Poke deal valued the startup in the 'low nine figures' (confirmed by co-founder Marvin von Hagen); Cognition co-founders Scott Wu and Walden Yan had been angel investors in Interaction, and the stated rationale was bringing Poke's interaction model and personality to Devin. (https://techcrunch.com/2026/07/24/why-cognition-bought-poke-ai-personality-is-becoming-a-competitive-advantage/)

Pierre separately said Poke uses Code Storage for more than just code. (https://x.com/maxiloh1/status/2089779755897815125)

- He replied to Pierre/@fat about corrupt-automation rollbacks ("imagine pushing a bad update that corrupts users automations and the fix is just git resetting head"). (https://x.com/maxiloh1/status/2092377440995697016)
- He reposted co-founder Marvin von Hagen's recruiting line: "we're a dense team of 10 jane street engineers, ioi medalists, and sunshine enjoyers down in palo alto." This describes the team he worked on, not his own olympiad record. (https://x.com/maxiloh1/status/2041240607117492455)
- He worked on Poke product surfaces in public, for example: "wanted poke to send me bugs proactively 🥰" (an internal proactive bug-report flow), and he answered user support questions about iMessage and SMS/WhatsApp access. (https://x.com/maxiloh1/status/1978898559916200002)
