## About this market
"AI marketing" sold to B2B buyers splits into measurement, visibility and tooling, and the firms on this page come at it from different ends.

Ekimetrics comes from measurement: two decades of marketing-mix modeling, with its most detailed published work—a climate-risk engine and a beauty-sector formulation system—anonymized. wukonig works visibility in AI assistants for industrial and B2B firms, with a published method: a fixed question set repeated across ChatGPT, Gemini, Perplexity and AI Overviews, scored against named competitors. Found runs AI-search tracking through its own Luminr platform alongside paid search and SEO, though no AI-answer outcome is published yet.

OstraconAI builds the tooling: an n8n and Gemini pipeline that scores and routes inbound leads into HubSpot for Singa, and AI-personalized outreach for Gosta Labs published with its full funnel—3,930 messages, 198 replies, 62 opportunities.

B2B marketing runs on long sales cycles, so the number that matters often lands after the engagement ends. Ask each candidate which metric they would commit to inside the contract period—pipeline, qualified leads, share of AI answers—and how it is measured independently of their own tooling.
