Reevo, the AI-native Revenue Operating System backed by Khosla Ventures and Kleiner Perkins, today announced it has acquired Ciro, a B2B prospecting agent that finds, qualifies, enriches, and drafts outreach to sales contacts at scale. The acquisition strengthens Reevo's built-in prospecting capabilities by integrating Ciro's multi-terabyte search index covering hundreds of millions of person and company profiles. Reevo has seen 4x growth since its November 2025 launch and now employs more than 90 people with senior leaders from Affirm, Airbnb, Box, DoorDash, HubSpot, Notion, Salesforce, Square, Rippling, and Uber.
Ciro's Prospecting Agent Integrates Into Reevo Platform
Ciro's prospecting agent is used by hundreds of sales teams to run outreach at a scale no human could match. The agent runs on a multi-terabyte search index covering hundreds of millions of person and company profiles, executing multiple search passes that progressively refine precision as the system learns what a customer actually wants. Companies use Ciro to handle prospecting for their sales development teams, building lists with more than ten qualifying criteria per contact. The agent remembers preferences over time: ideal customer profiles, exclusion rules, and outreach voice are learned once and applied automatically from that point forward.
With the acquisition, Ciro's technology becomes a native part of Reevo's prospecting engine. Reevo gives reps the ability to run prospecting in the same system where they manage their pipeline and close deals. Most B2B revenue teams use prospecting software that lives in a separate tool from the CRM and outreach platforms, requiring reps to export lists, re-verify data, and manually load contacts into a sequencer before a single email goes out. Reevo was built to eliminate that tool sprawl by building prospecting directly into the platform.
For Reevo customers, qualified leads appear inside the CRM already enriched, already scored, and already matched to the right account, with outreach drafted and ready to send.
Reevo CEO David Zhu on Eliminating Tool Sprawl
"Every revenue team we talk to is paying for four or five separate tools just to find out who to call. We built prospecting into Reevo from the start, and Ciro's agent makes it far more powerful — one of the best prospecting engines in the market, now running natively in the platform our customers already run their entire business on," said David Zhu, Co-Founder and CEO of Reevo. "This is what it looks like when revenue actually runs on autopilot. Not a dashboard that tells you what to do next. A system that already did it."
Ciro CEO Richard Lee on Strategic Fit
"Ciro and Reevo fit naturally together: prospecting that just works and an operating system built for it to run on. Combining them lets our system prospect with the intelligence of the full customer lifecycle, where everything learned downstream feeds back into who our customers go after next," said Richard Lee, CEO and Co-Founder of Ciro. "I'm incredibly bullish on what Reevo is building and how it'll serve our customers."
