[See every surface](https://humantic.ai/surfaces) - ### Complete Buyer Intelligence Everything about the buyer in one place: the account, each person on the committee, who is on your site and who is in market. [What is Buyer Intelligence?](https://humantic.ai/buyer-intelligence) ## FAQs - ### Is Humantic AI a good alternative to TheirStack for job and tech stack signals? It depends on the job. TheirStack publishes very large job and technology coverage, so it is the stronger pick if raw data volume is the whole job. Humantic AI Data Streams deliver live job postings and tech stack changes at the accounts you pick, and the rest of the suite turns a signal into action: account briefs, stakeholder profiles and guidance on how each buyer decides. - ### How do Humantic AI and TheirStack compare on people and stakeholders? TheirStack works at the company level and does not return contacts or people profiles, so teams pair it with another tool for the people. Humantic AI profiles each stakeholder, maps the buying committee and suggests how to approach each person. - ### Where does Humantic AI fit if we already use TheirStack? Keep TheirStack as a data source and add Humantic AI where reps work: Account Research Agent briefs on the accounts it surfaces, People Research Agent profiles for the people inside them, and Visitor ID to see which of those accounts visit your site. Humantic AI streams reach your systems by webhook or MCP. - ### What are the best TheirStack alternatives? The best TheirStack alternative depends on the job. For turning job and tech signals into action, Humantic AI is built for it.
