2X

2X is a B2B go-to-market services company that delivers what it calls GTM Human-Agentic Services — AI agents, expert embedded teams, and intelligent workflows sold through a subscription model rather than a traditional agency retainer. Founded in 2017 by three former B2B CMOs including Domenic Colasante, 2X grew out of Marketing-as-a-Service (MaaS) into full go-to-market orchestration spanning marketing operations, MarTech management, campaign build and demand generation, content and creative production, GTM engineering, and revenue strategy consulting. In June 2026 2X acquired Knownwell, an AI-as-a-Service commercial-intelligence platform, in a transaction valued at more than $400M; Knownwell founder David DeWolf became 2X's CEO and Colasante remained as founder. 2X also acquired GTM engineering firm The Kiln, a leading Clay implementation partner. With more than 1,000 team members across five continents, 2X serves over 150 enterprise clients including SAP, Ricoh, Docker, Seismic, Qlik, Brightcove, Emburse and GoTo, and is backed by private-equity firms Recognize and Insight Partners. Its public machine-readable API surface arrives through Knownwell — a documented REST API and an OAuth-protected remote MCP server for client, portfolio, and account-health intelligence.

2X publishes 10 APIs on the APIs.io network, including Alignment API, API Keys API, Clients API, and 7 more. Tagged areas include Company, Marketing, Marketing as a Service, B2B, and MarTech.

2X’s developer surface includes engineering blog, support, documentation, API reference, and 14 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/2x: open an issue to ask a question, or submit a pull request to add artifacts.

    customer stories, open roles, testimonials and media. It also carries one first-party namespace 2X built itself, maturity/v1,
    which serves the submission records behind 2X's marketing-maturity assessment. This is content infrastructure provided
    by the CMS, not a 2X product API — recorded because it is a genuinely callable public surface on 2X's own domain.

  detail: 2X now has a real machine-readable contract through its June 2026 acquisition of Knownwell — an anonymously-readable
    OpenAPI 3.1.0 with 27 operations at api.knownwell.com/openapi.json plus an OAuth-protected remote MCP server at mcp.knownwell.com/mcp.
    The prior profile was a stub because the catalog held only the superseded 2x.marketing domain and had never probed the
    acquired hosts.
