2. How Siro Works

  • Sales reps use Siro’s mobile app to record face-to-face sales conversations.
  • AI transcribes and analyzes these conversations to surface key insights, coaching opportunities, and behaviors that drive revenue.

3. Proven Results

  • Sales teams using Siro report:
    • 36% higher close rates
    • 30% lower sales rep turnover
    • 10x faster coaching cycles

4. Funding and Strategic Support

  • The $50 million Series B was led by SignalFire with participation from 01 Advisors, StepStone Group, and existing investors including CRV, Fika Ventures, and Index Ventures.
  • SignalFire’s Managing Director Wayne Hu highlighted Siro’s role in digitizing “dark matter” of offline sales conversations with broad applications.

5. Company Growth and Vision

  • Founded in 2020 by CEO Jake Cronin, a former top Cutco sales rep and McKinsey alum, Siro has grown rapidly with hundreds of customers in industries such as home improvement, med spas, and wholesale distribution.
  • Cronin’s mission is to make in-person sales a more accessible and rewarding career path.

Siro’s latest funding round fuels its mission to revolutionize in-person sales through AI-driven conversation intelligence. By making offline sales conversations visible and actionable, Siro helps companies improve sales performance, reduce turnover, and speed up coaching — reshaping the future of field sales.
