Sales Intelligence Platform

What profileAPI is

profileAPI is an intent signals tool in the B2B go-to-market stack. In the vendor's own words: “Sales Intelligence Platform.” Put plainly, a tool in this category flags the accounts showing buying behaviour right now, so the list is timed as well as targeted.

Where it sits in an outbound stack

Most outbound stacks are four layers: the data that decides who you talk to, the channel that carries the message, the writing that earns a reply, and the system of record that remembers what happened. profileAPI sits in the intent signals layer. Tools beside it are worth comparing on coverage and price; tools in the other layers are worth wiring to it rather than replacing it with.

Using profileAPI with M for Mercury

profileAPI is a data layer, and data is where LinkedIn outreach either works or wastes a sender. Mercury's Lead Finder searches 450M+ contacts and returns the LinkedIn profile to connect with alongside a verified work email, then enriches whatever is missing column by column. If profileAPI already holds your list, Mercury takes it from there: enrol the audience in a journey, spread it across senders, and pace every send inside safe limits.
