Tact.ai

Tact.ai was a Redwood City, California conversational-AI and field-engagement company founded by Chuck Ganapathi that built an AI sales assistant ("Tact Assistant") unifying CRM, email, and calendar data into a voice- and chat-driven interface for enterprise sales teams, later concentrating on the life sciences vertical. It was backed by Accel, Redpoint Ventures, Upfront Ventures, Microsoft's M12, and Salesforce Ventures. In November 2023 its field-engagement and conversational-AI technology was acquired by Aktana and the standalone company wound down. The tact.ai domain no longer hosts a product: it resolves to an Afternic domain-for-sale parking page (nameservers ns1/ns2.afternic.com), and the company exposes no public developer API, documentation, or developer portal to enrich.

Tact.ai is profiled on the APIs.io network. Tagged areas include Company, Enterprise, Conversational AI, Sales, and CRM.

Regulatory Posture applies to this provider. Its tags matched the Health regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/tactai: open an issue to ask a question, or submit a pull request to add artifacts.
