What they're building

Selling and expanding Hyperbound Practice, Hyperbound Perform and Kota strong signal

Today: Score real calls, practice with AI roleplays, and let Kota agents close the loop on every deal (site)

Roles: Enterprise Account Executive · Mid Market Account Executive, Existing Business · Technical Customer Success Manager, Mid-Market

Requirements mention: Hyperbound Practice · Hyperbound Perform · Kota · AI sales roleplay · full-cycle enterprise deals · expansion quota · renewals · rollout design · integrations setup · SSO and SCIM · admin training

Inference: alongside new enterprise deals, they are staffing to grow and keep existing mid-market accounts, through expansion quota, renewals and technical rollout. Based on posting wording only.

Voice AI and model work behind roleplay, scoring and Kota moderate signal

Today: Roleplay with realistic AI buyers; record and score conversations; Kota connects calls, roleplays, email, CRM and Slack (site)

Roles: Full Stack Software Engineer · Machine Learning Engineer

Requirements mention: Voice AI · Duplex models · GraphRAG · Context graph · MCP · Sub agents architectures · fine-tuning · evaluation frameworks · roleplay, scoring, and coaching products

Inference: engineering hiring centres on the voice roleplay, the scoring and coaching models, and connecting customer data for Kota. The postings name these techniques but do not describe a launch.

Internal systems for Hyperbound's own GTM team weak signal

Today: AI sales roleplay and coaching platform (site); this role builds internal tooling, not customer-facing product

Roles: Software Engineer, GTM

Requirements mention: lead routing · enrichment · pipeline and forecasting tooling · scoring · deal-desk workflows · data layer · CRM · billing data

None stated; a single role is too weak a signal to infer a next step.

Video and marketing content production weak signal

Today: AI sales roleplay and coaching platform (site)

Roles: Creative Video Producer / Motion Designer

Requirements mention: storytelling instinct · on-location production · direct interviews · explainer graphics · thumbnails, ad variants, social graphics

None stated; a single role is too weak a signal to infer a next step.
