About
Circleback is a San Francisco-based AI-powered meeting notes and action tracking platform — backed by Y Combinator (W24) with $3 million in total funding including a $2.5 million seed in November 2024 from YC, Rebel Fund, Pioneer Fund, Transpose Platform, and angels including Kulveer Taggar, Oliver Jung, JJ Fliegelman, Rich Aberman, and Jason Freedman — generating $16.8 million in annual revenue in 2024 with only 4 employees, achieving cash flow positive status through primarily organic growth, and serving thousands of paying customers. Founded by Ali Haghani (ex-Stripe) and Kevin Jacyna (ex-Tableau), Circleback automatically joins meetings (Zoom, Google Meet, Microsoft Teams), transcribes conversations with AI, generates structured meeting notes with action items, and distributes summaries to participants and connected tools (Slack, Notion, HubSpot, Salesforce).

About
Kustomer is an AI-powered customer service CRM platform providing a unified customer history view and conversational support tools for e-commerce, retail, and direct-to-consumer brands managing high-volume customer interactions. Founded in 2015 by Brad Birnbaum and Jeremy Suriel and headquartered in New York City, Kustomer was acquired by Meta (Facebook) in 2021 for approximately $1 billion, then resold back to its founders in a management buyout in 2023 — a rare reversal after Meta determined the business didn't fit its core strategy.
