ICPExplorer is stand-alone software for building and owning an Ideal Customer Profile database. Users define profiles by industry, company size, technology, and growth signals, then enrich company records with size, tech stack, funding, and growth indicators. Signal-based scoring explains why an account fits. A demo can generate similar companies from one URL and score them by industry, size, and technology. CSV export is available, while the demo provides a five-row export and a copy-top-five option. The local, no-signup demo uses synthetic data and is limited to 20 rows and three sessions per day. Starter is free with 25 enrichments, one ICP, and CSV export. Growth costs €490, paid once, includes the first-year SLA, and offers optional renewal at €120/year. Enterprise / Agency pricing is custom, with higher limits, multi-seat use, on-prem options, and optional CRM sync. The perpetual license continues without renewal, but new updates require an active SLA.
