Intro

Hi, I'm Adam. I'm an independent builder & industry analyst. My goal is to help GTM leaders make sharp decisions in uncertain markets.

This is my methodology for the GTM Index — the score, the rankings, and the category maps. Three principles guide this work:

1. Mindshare matters. We can gain an edge by understanding the conversations and perceptions within our market. This goes beyond reviews or narrow expert opinions.
2. Curation is judgement. My judgement is encoded into this research system by curating the panel and coverage. That's what makes this different from vanilla Claude queries on GTM tech.
3. Everything must update and evolve constantly. The traditional analyst model can't keep pace; this one runs continuously.

Coverage

I cover products and companies with a central application for B2B go-to-market in the AI era. Most are sales- or marketing-focused (e.g. Gong, Clay), but I also cover broader solutions that are clearly GTM-relevant (e.g. Claude Code, Vercel, Exa).

On the edges my judgement determines what fits (and what doesn't). Like all things, this evolves as I learn and as the market changes.

SOV Score

Your share of panel conversation, normalized 0–99 against the field.

That's the whole idea. It is a share-of-voice measure, not a rating: I am not scoring whether a product is good. I'm measuring how much of the GTM conversation it holds.

Here's how it works:

1. Curated Panel. Sources I've hand-picked across social media, newsletters, blogs, and podcasts. Not a broad sample — the best minds in GTM: operators, authors, builders, executives.
2. Tracking Mentions with Context. I track every product mention — and its context — across the panel.
3. Engagement Weighted. Each mention is weighted by engagement and relevance (the factors vary by mention type). A product's own posts don't count — the score is earned voice only.
4. Normalized 0–99. Every product sits on one scale, indexed to the loudest product in the window — that product scores 99 and everything else is placed against it. The index follows a power curve, not a straight line.

The two windows

Ninety days is long enough that one viral post doesn't decide a ranking, and short enough to still be about the present. Thirty days is where movement actually shows up — a longer movement window mostly reports slow drift.

Both are recalculated every night, against the panel as it stands that night. Scores as of 2026-07-26.

What the number is not

• It is not a percentage. A SOV Score of 40 does not mean 40% of anything. It's a position on a 0–99 curve where 99 is whoever the panel talked about most in the window.
• It is not linear. The curve compresses the top and spreads the bottom, so the gap between 90 and 95 represents far more conversation than the gap between 20 and 25. At the very bottom the scale is steep: roughly, SOV 9–11 is one earned mention over 90 days, 14–16 is two, 19–21 is five, 24–26 is nine.
• It is not a quality rating. A product can be excellent and quiet. That shows up here as a low score, and that is the measure working, not failing.

What counts as a voice

A voice is a source on the curated panel — a person or a publication whose GTM commentary I've chosen to track, across LinkedIn, X, newsletters, blogs and podcasts. It is a hand-picked list, not a crawl of the internet, and that curation is the product. Three rules keep it honest:

• Earned only. A brand's own accounts, and posts by its own staff, are identified and excluded. You cannot post your way up this index.
• Weighted by engagement. A post nobody read counts for less than one the market argued about.
• Context-checked. Common-word brand names ("Clay", "Air", "Enrich") are run through a context gate before a mention is credited, so an ordinary English sentence doesn't score for a vendor.

Markets, membership, and the ranking cutline

Brands sit inside Markets — the arenas they actually compete in. A Market is a curated call, not an algorithm.

Two different things can be true of a brand at once, and it matters which:

• Membership is permanent. Once a brand belongs to a Market it keeps that Market, whatever its score does. Membership is about what the company is.
• Ranking is dynamic. A brand is ranked once its SOV Score clears its Market's floor — currently SOV 15. Below that it keeps its Market and stays visible on the page, marked unranked.

One case sits outside both: a brand the panel didn't mention at all in the window has no score, so it isn't below the floor — there's nothing to be below. It keeps its Market and it's in the Index, but a Market page only shows brands the panel actually talked about. It reappears the moment it's mentioned again.

That split is deliberate. It means a quiet quarter doesn't erase a company from the Index, and a loud one doesn't require anybody to be manually let in. Entry and exit are just the score crossing a line.

Separately, some products are scored but never ranked — see GTM Adjacent below. Those are broad platforms GTM teams run on rather than GTM tools competing for the same buyer; scoring them is useful for comparison ("Clay now out-mentions X"), ranking them is not.

Category Definitions

GTM Tech Types

My highest level organizing framework has a strong bend toward AI. I believe the traditional categorization is breaking down quickly. This is how I see the space at a high level:

GTM Tech Categories

Categories are generally organized around use cases, go-to-market motions, or the intersection of the two. That said, there is a balance of many factors in this framework and it ultimately comes down to my judgement.

Rules & Guidelines

Products can fit types and multiple categories, but there must be a strong case.

Agent Readiness Score

I score Agent Readiness as a secondary factor, but it matters: in an agent era, whether your systems can actually build on a product matters more than its UI. It's an analyst-judged 0–99 score (with an A–F grade) across four surfaces — API, MCP server, SDK, and CLI — plus the quality of the docs behind them. Multiple agents, each with a different persona, assess those surfaces and docs; the Surfaces column shows exactly which a product ships.

Feedback & Corrections
