Aampe
Aampe is a San Francisco-based company building agentic AI infrastructure for personalized customer experiences. Instead of relying on generative AI, it assigns a dedicated reinforcement-learning agent to every individual user that continuously experiments and learns what content to send, when, and whether to send anything at all. The platform has deployed over 100 million agents across hundreds of consumer apps on four continents, helping product, data science, and lifecycle marketing teams move from rule-based campaigns to continuous, per-user adaptation.
Hightouch
Hightouch is a San Francisco-based B2B SaaS company that pioneered Reverse ETL and built the leading Composable Customer Data Platform (CDP). Founded in 2018 by Tejas Manohar, Josh Curl, and Kashish Gupta - all alumni of Segment - Hightouch lets companies activate their warehouse data directly into 250+ business tools like Salesforce, Braze, and Google Ads without copying data to a separate CDP. Since launching AI Decisioning in 2024, Hightouch has evolved into an agentic marketing platform, helping brands like Warner Music Group, Chime, PetSmart, and Spotify orchestrate personalized customer journeys using live warehouse data. The company reached $100M ARR and a $2.75B valuation in April 2026, backed by Goldman Sachs, Bain Capital Ventures, and Sapphire Ventures.
