Jack Dwyer works on developer experience at LiveKit and co-founded Gabber, a platform that helped small teams build affordable, expressive real-time voice and video applications. His products have focused on making conversational AI practical for consumer experiences, from communication coaching to interactive characters.
Before Gabber, Dwyer and his brother Neil founded a multiplayer gaming startup. After it closed, Jack built Rizz.ai, an AI conversation coach, during nights and weekends. The application simulated dating conversations and other social interactions, providing feedback to help users practice communication.
The brothers founded Gabber in 2024 to give developers the infrastructure behind comparable experiences: expressive voices, customizable personas, persistent memory, moderation, usage tracking, and real-time web and mobile integrations. Jack led product-facing work while Neil, Gabber’s chief technology officer, directed its technical architecture. Jack subsequently rebuilt Rizz.ai on Gabber, demonstrating how one SDK could support a consumer application without a separately maintained back end or database.
- Consumer voice AI needs consumer pricing. Gabber pursued $1-per-hour voice AI because premium infrastructure costs constrain applications such as coaching, education, interactive characters, and connected toys. Neil delivered their jointly credited conference session on open-source speech models, efficient inference, voice customization, and latency; one demonstration synthesized Jack’s voice.
- Continuous multimodal media flows. Gabber Cloud organized audio, video, models, and tools as continuously running graphs, allowing simultaneous inputs and outputs to influence an interaction as it unfolded.
- Reliable voice-agent development with coding assistants. At LiveKit, Dwyer co-authored guidance for building voice agents with AI coding tools, combining durable architectural instructions with live documentation and MCP access to prevent stale SDK assumptions and invented interfaces.
Gabber subsequently joined LiveKit, where Jack, Neil, and teammate Brian Blumenfeld continued developing real-time AI infrastructure. Jack’s role centers on making that infrastructure easier for developers to use.
