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 12 API contracts indexed on the APIs.io network, including Alignment API, API Keys API, Clients API, and 9 more. Tagged areas include Company, Marketing, Marketing as a Service, B2B, and MarTech.

The 2X catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

2X’s developer surface includes engineering blog, support, documentation, API reference, and 23 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

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.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
Typed Event Surface +6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks
Documented Reversibility +6 pts — a reversal operation in the contract, graded up when a window is documented too
Pagination +5 pts — share of collection GETs (an array, or one wrapped in data/items/results ...) that declare a page/limit/offset/cursor parameter, a Link header or a next/cursor field; na with no collection GETs

4 more unmet checks in the Agent Readiness table above.

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.

  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.
