Applied AI labs building targeted voice, fintech and edge-AI systems
Strategy, deployment and operations engagements that help leadership teams architect and operationalize AI systems, starting from the specific problem rather than a product demo.
AI is deployed only in carefully selected domains where it targets a measurable bottleneck, avoiding blanket automation and 'transformation theater'.
Products such as Fulcrum AI (SMB operations), NexDex (frontier-tech equities) and vibestreet (an AI component marketplace) demonstrate the same targeted-AI thesis in production.
The emergE initiative explores running AI locally on GPU-equipped mini computers with AI-native file systems, reducing latency, preserving privacy and avoiding heavy AI engineering overhead.

AI voice agents that run your customer calls end to end
telli Studio lets teams create and refine agents by describing the conversation in natural language, without engineering work.
Deploy agents with native fluency, local accents and cultural context across 30+ languages, with curated voices and optional voice cloning.
Pre-built and custom actions let agents act during a call, while post-call workflows push outcomes into connected systems automatically.
Native Salesforce and HubSpot connections plus API access, with telli phone numbers or bring-your-own via SIP trunking.
