Sherlock helps SaaS businesses to find product qualified leads, convert them, and retain them. To use the tool, users need to sign up first. After the sign-up process, they can connect their Segment account or use the provided API. Users need to create an engagement score and define the activation criteria. They can start scoring product engagement by ranking individual events based on the level of importance. It's also needed to set up an account activation checklist in Sherlock, after which activation rates will be displayed as a percentage. The higher the percentage, the more likely it is that the user has a product qualified lead. Users can also access a list of their users and accounts ranked by engagement level, drill down to individual profiles, and find out which accounts are PQLs. The identified leads can then be sent to their existing workflows via integrations with Slack, Salesforce, and Intercom.
