HubSpot led the Gartner Magic Quadrant for B2B Marketing Automation Platforms for the sixth year running in 2026. Oracle has led it for fourteen. In a market with that much incumbency, two notable new platforms still launched this year, and neither one is trying to out-feature the leaders at what the leaders already do well.
Phave, built for buying groups. Marketo co-founder Jon Miller’s new platform targets a structural gap: most marketing automation still scores and nurtures individual leads, while actual B2B deals are decided by buying committees that have only gotten larger. A platform built around the account’s whole stakeholder group rather than a single contact record is a different data model, not a feature bolt-on to an existing one.
Haus Architect, built for budget decisions. The second new entrant takes a narrower, sharper slice: causal marketing mix modeling that simulates what happens to pipeline if budget moves between channels, then executes the adjustment. That is a tool for one specific, recurring decision (where should the next dollar go) rather than a general campaign platform.
Why the incumbents have not closed these gaps themselves. HubSpot and Oracle are optimized for breadth: CRM, service, commerce, and marketing in one suite, which is exactly why enterprise buyers pick them. That breadth is also why a narrow, purpose-built tool can still find room to launch against them. A platform built for everything is rarely the fastest to rebuild its core data model around something as specific as buying-group structure.
What this signals for buyers. The practical read for 2026 is not “replace your platform.” It is that the biggest unsolved problems in B2B marketing automation (who actually makes up the buying group, and where should the next dollar of budget go) are specific enough that point solutions are still finding real openings against platforms with over a decade of incumbency.
