ZoomInfo, the all-in-one AI GTM platform, has released GTM Bench, a versioned benchmark that evaluates LLMs and AI agents on the work go-to-market teams actually do: building target lists, enriching records, scoring accounts, and reaching decision-makers. Version 1 covers more than 20 jobs, 4 systems, and 3 models, and the methodology, sample tasks, and grading rubrics are published for scrutiny.
GTM Bench evaluates LLMs and AI agents on real GTM work across two axes: Answer (work product completeness) and Grounding (data verifiability).
ZoomInfo's GTM.AI scored 77 GTM Bench Index vs 47 (Apollo), 36 (Exa), 31 (open-web search).
GTM.AI finished 98% of operator's work product; returned 478 verifiable records per 1,000 vs 7-35 for competitors.
GTM.AI ran at $0.79 per task; non-ZoomInfo field returned 720 wrong phone numbers on 1,000-contact suite.
GTM.AI exposes GTM Context Graph with 100M companies, 500M contacts, billions of signals.
Competitors can submit systems to be run and added to leaderboard.
Most AI benchmarks measure reasoning inside a closed world. They hand the model the facts and grade how well it reasons over them. Go-to-market fails differently. The constraint is data availability: roughly 70% of B2B contact data decays every year. Every GTM Bench result is graded against a senior GTM operator's work product on two independent axes: Answer measures what share of the requested work product the system delivers; Grounding measures what share of the returned data traces to a real, current source. A confident wrong answer scores negative.
In the v1 run, ZoomInfo's GTM.AI led every pillar, with a GTM Bench Index of 77 against 47 for Apollo, 36 for Exa, and 31 for open-web search. It finished 98% of the operator's work product, returned 478 verifiable records per 1,000 against 7 to 35 for the field, and ran cheapest at $0.79 per task. On the same 1,000-contact suite, the non-ZoomInfo field returned 720 wrong phone numbers.
GTM Bench is a vendor-run benchmark, and ZoomInfo publishes it accordingly. The losses are shown plainly, including four categories where the ZoomInfo edge is thin or absent. Grounding is graded against ZoomInfo's verified records, a reach measure rather than an independent audit. The benchmark is versioned, will be re-run on major model releases, and version 2 adds agentic multi-step workflows, international coverage, and an owned-data axis.
Other data providers and agent builders can submit their systems, and ZoomInfo will run them at their best configuration and add them to the leaderboard. GTM.AI powers dozens of live integrations, including Salesforce Agentforce, HubSpot Breeze, Microsoft Copilot, Claude, ChatGPT, Gong, LeanData, and Google Workspace.
