email integration Startups

Gong.io is a revenue intelligence platform that automatically captures and analyzes customer interactions from calls, emails, and meetings to provide actionable insights for sales teams. Founded in 2015 by Amit Bandop, the company grew from 200 customers in early 2018 to approximately 1,500 customers serving over 60,000 sales reps, with expansion revenue driving exceptional net revenue retention of over 150%. After raising a Series D of $200 million at a $2.2 billion valuation, the company is approaching a $45+ million run rate and expects to approach $100 million ARR in the near term.

X.ai is an AI-powered personal assistant that schedules meetings via email on behalf of users. Founded by serial entrepreneur Dennis Mortensen after he sold his previous analytics company and discovered he had 1,019 meetings in a year (65% requiring rescheduling), X.ai has raised $44 million and uses a novel approach of testing market viability before building the full product—starting with a concierge MVP and only then raising seed funding to validate the technical approach through data labeling.
