Apten
Apten is a Y Combinator (S24) startup building omni-channel AI agents that engage and nurture leads across SMS, voice, email, and webchat. Aimed at B2C enterprises in home services, insurance, education, healthcare, and financial services, its agents hold one continuous memory across every channel, follow up at the right moment, transfer live calls to humans, and plug into CRMs like Salesforce and HubSpot. The company says its conversational approach converts previously dead leads into sales opportunities at a much higher rate than robocalls or static drip campaigns.
Privyr
Privyr is a Singapore-based mobile-first CRM built for salespeople and small businesses who work primarily through WhatsApp, SMS, iMessage, and phone calls rather than at a desk. It connects to lead sources like Facebook, TikTok, Google and web forms, alerts users the moment a lead arrives, and lets them respond with personalized messages, automated follow-ups, and trackable content - all from their phone. Founded in 2018 by Aaron Lim and Shivam Mani Tripathi, Privyr says it is used by hundreds of thousands of businesses across 125+ countries and raised a $6M Series A in 2022 led by MassMutual Ventures and Vulcan Capital.

Sybill
