#About gtmcanon

gtmcanon is the reference for go-to-market software. Independent reviews, citation-disciplined, no sponsored placements. Every claim resolves to a permalinked source. The best tool wins regardless of who pays.

#The vision

gtmcanon gives the best go-to-market software the attention it deserves. The premise is that a procurement officer, an operator, or a founder should be able to open a single page, read a dated review with every claim sourced, and walk away knowing which tool to buy and why. No pay-to-play tier. No anonymous quorum. No analyst with a vendor on retainer.

The category gtmcanon covers is broken. G2, Capterra, TrustRadius, and the analyst-paid Magic Quadrant class all run on vendor money. Their rankings are for sale; their methodology is opaque. Operators have noticed: searches for "best [GTM tool]" route to Reddit, Pavilion, WizOps, and Perplexity. Reddit alone accounts for roughly half of Perplexity's citations on B2B SaaS recommendation queries.

Reddit is where the signal lives. It is also unstructured. A procurement officer cannot send a thread to the CFO. A new SDR cannot rely on it surviving the next platform-versus-LLM lawsuit. An answer engine can ingest it but cannot easily verify it.

gtmcanon is the structured layer above that operator discourse. The same evidence, cited and dated and audited. Same material. Different epistemic status.

#How it works

Reviews are scored against a public rubric. Sources are permalinked and dated. Pricing is verified against vendor pricing pages on the day the review is dated. Every review is re-verified every ninety days, and every substantive change since first publication is logged in the revision history on the page itself.

The structural commitments at /editorial-standards make these promises testable. The methodology at /methodology makes them auditable.

#The canon, by volume

The canon is organized into volumes, each covering a single go-to-market category from inclusion criteria through final scoring. A volume opens when the category is structurally underserved by existing leaderboards. A volume closes when it has matured to ten to fifteen reviewed tools. The publication date and methodology version of each review are visible on the review itself.

Volume I — AEO Tools. Software for tracking brand visibility in AI answer engines (ChatGPT, Perplexity, Claude, Gemini, AI Overviews). The first review is published: Peec AI. More are in research at /aeo-tools.

Volume II — To be announced. The candidates are Sales Engagement and Data Enrichment. The choice is decided by operator demand and where the existing leaderboards have failed most visibly.

Volume III and onward. Adjacent categories in the go-to-market stack. The full sequence is published when Volume II opens.

#Who publishes this

gtmcanon is published by Tiên Grünewald, founder of Superscale. Before Superscale, Tiên ran a software agency working with European startups including Gorillas, Neotaste, Deeploi, and Tink.

Superscale is not a tool that appears in gtmcanon coverage. If that ever changes, the disclosure will be added to the affected review pages and to /editorial-standards.
