Marketo co-founder Jon Miller launches Phave, an AI-driven marketing automation platform targeting buying groups

Jon Miller, co-founder of Marketo and a key architect of the MQL-driven marketing playbook, launched a new company on September 23, 2026 that is built around a direct critique of the system he helped create. The company, Phave, says B2B marketing software still requires specialists to write rules for journeys that buyers rarely follow in a tidy sequence. Miller co-founded Phave with Nick Bonfiglio, Marketo's former EVP of Global Product, according to the company's launch announcement on PR Newswire.

Bonfiglio's background spans product management, engineering, cloud operations, and technical support at Marketo. He later founded Aptrinsic, which became Gainsight PX, and co-founded data-integration company Syncari, according to his Syncari biography. The Phave launch reunites two executives who worked on the incumbent platform they now want customers to replace.

The Maestro engine and its "Playlist" model

Phave's core product, called Maestro, computes a "Playlist" for each person — an ordered and timed set of approved marketing touches aimed at an objective the marketer selects. Maestro considers other campaigns already queued for a given person before choosing what comes next. Marketers create and approve the campaigns; Maestro decides how to combine them for each recipient.

Phave's data model gives accounts and buying groups their own scores and lifecycle stages, so one account can contain multiple committees, including prospects and existing customers. The platform allows marketers to describe campaigns, audiences, scoring, and automations in plain language, and can be accessed through Phave's own interface, an existing AI client, MCP, or a versioned REST API. Consent, frequency limits, and quiet hours remain rules; Maestro handles the choice between eligible messages.

Phave's starting price is $36,000 a year, calculated by how many people receive something in a month rather than by the size of a stored database, according to the launch announcement.

A self-produced competitive benchmark

Phave says it compared itself with incumbent platforms across 481 requirements drawn from 12 enterprise evaluations. According to the launch announcement, Claude scored and weighted the requirements, giving Phave a 2.97 score, HubSpot 2.46, and Marketo 2.38. Phave also says it matched or beat every evaluated platform on at least 90% of the requirements.

Those results are a company-produced comparison, not an independent benchmark. The launch announcement does not establish the full evaluation set, how competing products were configured, or whether the scoring method was independently audited. Phave says its methodology is published on its website.

Early customers and backers

Phave says it reached general availability in August 2026 and names SambaNova, SPS Commerce, mabl, Servion, and Hypha among its enterprise users. Servion's chief growth officer, Bruce Eidsvik, said in the launch announcement that the platform more than doubled the company's marketing execution volume. The announcement supplies no baseline or measurement period for that claim.

The company says it is backed by FirstMark, Ridge Ventures, and Costanoa Ventures. It did not provide a funding amount or valuation in its launch announcement.

Miller's argument against the system he built

Miller previously co-founded Engagio to tackle account-based marketing after finding that Marketo's lead-centered model made it difficult to coordinate campaigns around whole accounts. Phave extends that progression: its thesis is that software should represent buying groups directly, and that AI should handle sequencing that marketers have struggled to maintain with fixed journeys.

Phave names Marketo, HubSpot, Pardot, and Eloqua as platforms it aims to replace — an ambitious claim in a market where installed systems often hold years of campaign logic and customer data. Phave says it supports migration from legacy platforms, but the launch announcement provides no migration volumes or quantified results.

Phave's launch announcement says the company spent two years in stealth. Miller and Scott Brinker are scheduled to discuss the future of marketing automation at an online event on September 29, 2026.
