LumenAI announced a $45 million Series B led by Horizon Ventures with participation from existing backers and strategic automotive partners. The startup, founded in 2021, builds real-time speech-to-UX pipelines that convert spoken requests into actionable UI flows for apps, IVIs, and contact centers.

The company says the new capital will accelerate enterprise sales, expand its SDKs for mobile and embedded systems, and fund a planned push into regulated industries where latency and privacy are critical. LumenAI highlights a hybrid edge/cloud model that keeps sensitive voice features on-device while syncing context to secure cloud models for longer-term learning.

Product updates arriving with the round include a developer portal with low-code flow builders, new connectors for Salesforce and ServiceNow, and an edge runtime that supports ARM Cortex and RISC-V platforms. The startup claims customers can reduce handle time by up to 30% through voice-driven UI automation.

Investors cited the rise of multimodal UX and the need for deterministic conversational routing as reasons for backing LumenAI. The company will hire across engineering and enterprise sales and plans a public SDK beta later this year.
