Marketo Co-Founder Launches AI-Native Marketing Automation Platform

Phave emerges from stealth with reasoning-based approach

Jon Miller, who co-founded Marketo and Engagio, has launched Phave, a marketing automation platform built around AI reasoning rather than pre-configured rules. The company emerged from two years in stealth mode and reached general availability in August 2026, according to details first reported by PR Newswire.

Phave positions itself as a direct replacement for established platforms including Marketo, HubSpot, Pardot, and Eloqua. Miller co-founded the company with Nick Bonfiglio, who previously led product and engineering at Marketo. Enterprise customers already using the platform include SambaNova, SPS Commerce, mabl, Servion, and Hypha.

How reasoning differs from rules

Traditional marketing automation platforms operate on explicit rules: predetermined logic for segmentation, lead scoring, and message sequencing. According to Miller, this approach forces marketing teams to simplify their programs because rules cannot handle ambiguity or make judgment calls. Most mature programs run only two or three nurture tracks, not because buyer journeys are simple, but because that's what rule-based systems can manage.

Phave's core technology, called Maestro, computes what the company calls a "Playlist" for each contact—a personalized sequence of marketing touches ordered and timed for that individual. Before sending anything, Maestro evaluates everything queued across all campaigns for that person. Marketing teams create campaigns (which Phave calls "albums"), and Maestro determines the optimal order and timing for each recipient while respecting governance rules around consent, frequency, and quiet hours.

The platform allows marketers to describe objectives in natural language rather than through configuration interfaces. It can be operated through its own UI, through existing AI clients, or headlessly through MCP and a versioned REST API, with consistent permission enforcement across all access methods.

Account-based and buying group support

Phave treats accounts and buying groups as distinct records, each with independent scores and lifecycle stages. A single account can contain multiple buying groups simultaneously at different stages—some as prospects, others as existing customers. This architecture addresses a common limitation in legacy platforms when marketing to expansion opportunities within existing accounts.

Bruce Eidsvik, Chief Growth Officer at Servion Global Solutions, noted that traditional platforms make it "practically impossible" to target a single account with multiple global sites and buyers across different departments. His team has more than doubled marketing execution volume using Phave's playlist approach.

Pricing and market positioning

Phave starts at $36,000 annually, with pricing based on the number of people who receive content each month rather than total database size. The company conducted a self-assessment against 481 requirements from twelve enterprise evaluations, with each requirement scored by Claude rather than by Phave staff. In that analysis, Phave scored 2.97 compared to HubSpot's 2.46 and Marketo's 2.38.

The company is backed by FirstMark, Ridge Ventures, and Costanoa Ventures.

Why it matters

The launch represents a direct challenge to marketing automation incumbents that have seen limited innovation in recent years. By rebuilding the category around AI reasoning rather than rule engines, Phave addresses a fundamental constraint that has limited how sophisticated B2B marketing programs can become. For enterprises managing complex buying committees and multi-product portfolios, the ability to orchestrate personalized sequences without exponentially increasing configuration complexity could meaningfully change what marketing operations teams can execute.
