Marketo's co-founder launches Phave, an AI reasoning engine aimed at replacing rules-based marketing automation

Jon Miller, who co-founded Marketo and later Engagio, came out of stealth on Sept. 23 with Phave, an AI-native marketing automation platform pitched explicitly as a replacement for the rules-based tools he helped invent. His co-founder is Nick Bonfiglio, who ran product and engineering at Marketo. The company reached general availability in August 2026 with named customers including SambaNova, SPS Commerce, mabl, Servion, and Hypha.

The technical claim sits inside a reasoning engine called Maestro, which computes a per-contact and per-buying-group sequence Phave calls a Playlist. The pitch to displace HubSpot, Pardot, Eloqua, and Marketo rests on a simple observation about what rules can and can’t do.

“Rules are good at what is allowed, but bad at deciding what is best. Consent, frequency and quiet hours should be rules. Choosing which of two good emails a person should get was never a job for a rule,” Miller said.

That framing matters because most B2B teams, especially in the 5-to-30-person range, end up running two or three nurture tracks in mature programs, because that’s all a rules engine can practically maintain. The bottleneck isn’t strategy. It’s configuration.

Phave is enterprise-tier, starting at $36,000 a year, metered on monthly active recipients rather than database size. Alongside the launch, the company published a self-scored benchmark placing Phave at 2.97 against HubSpot’s 2.46 and Marketo’s 2.38, across 481 requirements drawn from twelve enterprise evaluations and weighted by Claude. MarTech Edge noted, correctly, that these are the company’s own numbers.

The launch lands in a specific week. It follows Nimble’s AI sequencing launch last week at the small-business end and HubSpot’s Unbound push to rebuild its CRM around agents at the incumbent end. Every layer of the stack is being repitched as AI-native inside a single quarter. Miller and Scott Brinker of chiefmartec are scheduled to discuss the launch on Sept. 29 at 10 a.m. PT, which will extend the conversation past the press-release cycle.

The interesting move is Miller building the thing designed to obsolete his own invention. Category founders rarely get a second turn at the same category. When they take it, it’s usually because they’ve concluded the first version was a local maximum.
