Userflow

Userflow builds in-app tours, checklists, and surveys for SaaS companies. In practice that means replacing internal email with channels and direct messages.

The natural audience is every team. Alongside the main category they mention Messaging and Mobile. They are a very small team, 1 to 10 people, which usually shapes who they work with. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

Userflow is based in San Francisco, California. You can read more at userflow.com.

Things worth asking about: search, retention policies, and external guest access. Get the renewal terms in writing before the first invoice.
