WhatRuns

What WhatRuns is

WhatRuns is a technology lookup tool in the B2B go-to-market stack. In the vendor's own words: “Discover Website Technologies.” Put plainly, a tool in this category tells you what software a company runs, so you can target by stack.

WhatRuns appears in 2 categories here — Technology Lookup, Prospect Insights — which usually means it covers more than one job rather than doing a single thing narrowly.

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. WhatRuns sits in the technology lookup 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 WhatRuns with M for Mercury

WhatRuns 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 WhatRuns 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.
