Headsum is a live sales-support product designed to help teams handle complex B2B customer conversations with confidence. It brings approved company knowledge and relevant guidance into meetings, so sales professionals can find answers and respond to detailed questions without pausing for another meeting or internal handoff. Headsum also offers AI coaching, including suggested follow-up questions to help users explore customer needs and identify gaps in current processes.

Teams can add their expertise by uploading playbooks, presentation decks, and product materials. During a meeting, Headsum follows the conversation and surfaces relevant answers and guidance as they are needed. The product is designed to work without a meeting bot and is available to download for Mac.

Headsum aims to help account executives, sales managers, SDRs, sales leaders, and founders make shared team knowledge more accessible. This can give sales professionals greater confidence, help customers receive clearer answers, and allow specialist expertise to support more conversations without requiring specialists to attend every meeting.
