Cello: B2B Referrals, Authenticated Social Proof & the GTM 10 Awards

The Cello interview wraps up with the guest explaining why B2B referrals never scaled like B2C and why authenticated human social proof will be the key signal for both human buyers and AI agents. He points to CAC paybacks 5x-ing over five years, Google AI Overviews cutting search traffic by ~79%, and cold-call pickup rates halving as AI floods channels with noise. He describes Cello's growth-loop go-to-market model and its positioning for agent-to-agent commerce (e.g., agents choosing Stripe or Supabase), then promotes the second annual GTM 10 awards run with Lightspeed Venture Partners.
