FuseAI sits where a prospecting tool, a data enrichment service and a sequencing tool used to sit separately. Its agents search a contact and company database, enrich each record against a very large set of external providers, and then push qualified prospects into outbound sequences. The pitch is accuracy: rather than trusting one database, the platform cross-checks records so reps spend less time on bounced emails and stale titles.
Beyond prospecting, the platform watches for buying intent. Website visits, web activity and competitor interactions on target accounts act as signals, so a rep can prioritise the accounts that are already moving instead of working a static list top to bottom. Workflow automation then handles the repetitive parts, with triggers and conditions that update CRM records, enrich new leads and launch outreach without manual steps.
Engagement runs across email, LinkedIn and phone, with campaign analytics showing which audiences and messages produce opens and replies. Fuse is open by design, able to replace point tools or sit alongside an existing stack, and it now exposes an MCP endpoint so agents such as Claude can drive sales workflows. It is backed by Y Combinator and offers a free starting tier plus paid plans.
