Inflection AI — Startup ProfilePersonal AI for EveryoneHQ: Palo Alto, CA, United States | Founded: 2022 | Employees: ~35 (2026) — ~70 pre-March 2024 | Stage: Enterprise Pivot / Growth | Website: https://inflection.aiAboutInflection AI was founded in early 2022 by Mustafa Suleyman (DeepMind co-founder), LinkedIn co-founder Reid Hoffman, and DeepMind principal scientist Karén Simonyan. Incubated at Greylock Partners where Suleyman and Hoffman were partners, its mission was to build personal AI for everyone — an empathetic, trustworthy companion called Pi (Personal Intelligence) powered by frontier in-house models Inflection-1, Inflection-2 and Inflection-2.5. Built as a Public Benefit Corporation in Palo Alto, it partnered closely with Microsoft and Nvidia to train models on a cluster of 22,000 Nvidia H100 GPUs, positioning Pi as a challenger to ChatGPT and Claude with a focus on emotional intelligence and conversational support rather than productivity alone.After raising $1.3B at a $4B valuation in June Key Metrics
