AUI's Ascent

AUI has transitioned from stealth to scale-up mode over the last year making a number of upper tier hires and increase the drumbeat around the firm's native AI capabilities. In early November 2025, the company raised $20 million at a $750 million valuation cap, bringing total capital to nearly $60 million. The round drew participation from eGateway Ventures, New Era Capital Partners and existing shareholders.

In 2025 AUI launched Apollo-1, its neuro-symbolic AI model designed for customer service agents, complete with native connectors to Salesforce, HubSpot and Zendesk, complemented by open APIs and multimodal capabilities.

Market Context: Get Those AI Agents Trained

Trainable AI agents are transforming contact centers by automating routine tasks and enabling proactive support, freeing human agents for complex interactions.

Gartner predicted that by 2027, up to 40% of customer service issues could be fully resolved by generative AI-powered third-party tools.

The shift toward AI-augmented operations allows contact centers to function as value centers rather than cost centers, with agents focusing on retention and relationship-building.
