Marketo Co-Founder Jon Miller Launches Phave, Marketing Automation That Reasons Instead of Following Rules ...Middle East

BURLINGAME, Calif., Sept. 23, 2026 — Jon Miller, co‑founder of Marketo, has unveiled Phave, an AI‑native marketing automation platform that emerged from two years in stealth and aims to supplant legacy systems such as Marketo and HubSpot. The company says Phave “replaces legacy platforms like Marketo and HubSpot with AI that decides what each person, account and buying group should receive next,” positioning the product as a departure from rule‑based automation toward a decisioning engine that “reasons instead of following rules.”

“Phave replaces legacy platforms like Marketo and HubSpot with AI that decides what each person, account and buying group should receive next,” the company said in its launch announcement.

What Phave offers

Phave launched publicly on Sept. 23, 2026 after two years of development. The platform is described as “AI‑native marketing automation,” built to make autonomous decisions about next best actions for individual contacts, accounts and buying groups rather than depending on human‑authored workflows and static rules. The product is presented as a direct challenge to established marketing stacks, naming Marketo and HubSpot as incumbent platforms it seeks to replace.

The company is headquartered in Burlingame, California, and the timing of the announcement signals an intensified push by veteran marketing technologists to apply generative and decisioning AI to customer engagement and revenue operations. By shifting from rules to reasoning, Phave’s founders aim to reduce manual campaign orchestration and improve personalized sequencing at scale.

Context and industry impact

• Founder: Jon Miller, co‑founder of Marketo.
• Development: Two years in stealth prior to the Sept. 23, 2026 launch.
• Positioning: Targets legacy marketing platforms including Marketo and HubSpot.
• Core claim: Uses AI to decide what each person, account and buying group should receive next.

Marketing automation has long relied on human‑authored rules, segmentations and campaign trees. Phave’s pitch — that automation should “reason” rather than simply execute predefined logic — reflects broader industry shifts toward applying machine reasoning and multi‑model AI to operational decisioning. If Phave’s models can reliably recommend and execute next steps for complex B2B buying groups, it could alter how demand generation, ABM and customer lifecycle management are managed.

Outlook

Execution will determine whether Phave displaces entrenched systems. Legacy platforms benefit from deep integrations, large customer bases and extensive partner ecosystems; Phave must demonstrate not just superior AI but reliable data connectivity, compliance controls and measurable ROI to win migrations. The company’s explicit naming of Marketo and HubSpot sets a high bar for product parity and enterprise readiness.

For marketing and revenue operations teams weighing a move away from rule‑driven automation, Phave’s emergence adds a new option focused on AI decisioning. The coming months should reveal pilot outcomes, customer wins and integration partners that will indicate whether Phave’s reasoning approach scales across varied B2B buying models.
