AscentCore's work spans two distinct value propositions: (1) building custom AI-powered products for client companies (LLM applications, agents, ML systems, AI-native platforms), and (2) using AI internally throughout the software development lifecycle to deliver faster and at lower cost on traditional software engagements. Engagement models include dedicated managed teams, and full-cycle product development. Industries served include media and publishing, automotive, cybersecurity, civic technology, and consumer platforms.
