Probook Just Raised $40M To Run Dispatch For The Trades

Today’s RIP: Probook closed $40M between Series A and Seed. a16z and Sequoia split the lead. Use of funds is “scale go-to-market,” which is venture language for “hire AEs fast.” The CRM that worked for 8 reps almost never works for 20.

THE DEAL

Probook announced $40 million in combined funding on June 23. Andreessen Horowitz led the $34M Series A. Sequoia led a parallel $6M seed and stepped into the A as well. New York based. Founded by Ben Cervantez, George Eliadis, and Lewis Zhang.

The product is an AI operating system for home services contractors. Plumbing, HVAC, electrical, roofing. The pitch is that dispatch is the central nervous system of every trades business and everything else (intake, customer messaging, data scrubbing, outbound) should flow through it.

Customer mix from the release: contractors are already moving from pilots into full deployments. That’s the tell that matters for what comes next.

THE PATTERN

The use-of-funds language is direct: “scale go-to-market operations in response to surging demand, while simultaneously expanding engineering and customer success teams.”

For RevOps operators reading the tea leaves, that’s three predictable second-order effects.

AE headcount doubles in 90 days. Always does at this stage. The MQL definition written when there were 8 AEs starts costing real pipeline at 20. The lifecycle stage logic written for one buyer persona starts mis-routing when the team adds enterprise segments. The forecasting model written for a 90-day sales cycle drifts when contractor deals start closing in 14 days because the demand is that hot.

CS hires a head, who hires three. The post-funding playbook for B2B SaaS is to name a head of CS, who then hires CSMs faster than there are playbooks to onboard them. Accounts get handed off mid-pilot with no documented handoff. The CSMs build their own systems. Six months later, every CSM has a different definition of “healthy.”

Engineering throws bodies at the integration backlog. Home services has a long tail of vertical SaaS tools that need to be integrated into a dispatch nerve center. HousecallPro. ServiceTitan. Jobber. QuickBooks. Plus the inbound channels (Google LSAs, Angi, Thumbtack, Yelp). The eng team that shipped the core product is now spending half its cycles on integration adapters. That’s where velocity dies.

WHAT WE’LL WATCH

A real RevOps stack at the Probook stage isn’t a finished thing. It’s a calendar of inevitable breakages. The watch list:

When	What usually breaks
Day 30	The new AE cohort hits onboarding without enablement material that matches the new vertical mix
Day 60	Lead routing rules stop matching reality; sales ops starts manually re-assigning
Day 90	The forecast model misses by 30%+ because the deal-shape distribution shifted
Day 120	First CS escalation reaches the CEO because no one owns the post-pilot handoff

None of this is a Probook-specific prediction. It’s what happens at every Series A B2B SaaS that doubles AE count in a quarter. The companies that handle it well rebuild the CRM stack before day 60. The companies that handle it badly are still using the original setup at day 180 and wondering why the new AEs aren’t ramping.

POPS & DROPS

• The round: $40M total. $34M Series A + $6M Seed.
• The lead: a16z on the A. Sequoia on the seed and the A.
• The customers: contractors moving from pilot to full deployment.
• The bet: dispatch is the nerve center, everything else is a feature.
• The next 90 days: AE hiring binge. CRM stack starts cracking around day 60. Predictable, recoverable, expensive if ignored.
