Led by SignalFire, the round fuels growth of AI-powered conversation intelligence platform built for face-to-face sellers

NEW YORK, May 22, 2025 /PRNewswire/ — Siro, the AI-powered conversation intelligence platform for in-person sales, today announced it has raised $50 million in Series B funding led by SignalFire, with participation from 01 Advisors, StepStone Group, and existing investors CRV, Fika Ventures, and Index Ventures. The funding will be used to accelerate product development and expand the team across engineering, sales, and customer success.

While technology has advanced rapidly for remote work and digital sales, field sales teams have been largely left behind. Siro changes that by turning real-world conversations into structured, searchable data – giving companies visibility into what’s actually happening at the kitchen table, on the job site, or in the showroom.

Using Siro’s mobile app, reps record their in-person sales conversations. AI then transcribes and analyzes the recordings, surfacing key insights, coaching opportunities, and revenue-driving behaviors. Sales teams using Siro have seen 36% higher close rates, 30% lower rep turnover, and 10x faster coaching cycles.

“As an AI and data company ourselves, we at SignalFire are very interested in companies building vertical specific data moats,” said Wayne Hu, Managing Director at SignalFire. “Siro’s solution is helping digitize the ‘dark matter’ of offline conversations comprising field sales engagements, which has broad extensibility across verticals and depth in downstream actions that can be instrumented from this data – such as customer and product insights.”

Founded in 2020, Siro has grown rapidly, with hundreds of customers across industries like home improvement, med spas, and wholesale distribution. Siro CEO Jake Cronin, a former top Cutco rep and McKinsey alum, started Siro to make in-person sales a more accessible path to financial freedom.

“Sales changed the trajectory of my life,” said Cronin. “This raise helps us build the tools to help others do the same.”
