Hermes

Real-Time Voice Intelligence Platform

A low-latency orchestration platform that transforms live speech into reliable AI conversations through streaming speech recognition, agentic reasoning, retrieval, and neural speech synthesis.

01 — Problem

Building conversational voice AI requires far more than speech recognition. Audio streaming, reasoning, retrieval, tool execution and speech synthesis must all operate together under strict latency constraints while maintaining conversational context.

03 — Tradeoffs

Prioritized modularity and extensibility over a tightly coupled pipeline. Independent services introduce orchestration overhead but enable each subsystem to evolve without affecting the entire platform.

06 — Lessons Learned

Real-time conversational AI is fundamentally an orchestration challenge. Keeping speech, reasoning, retrieval and synthesis loosely coupled produces systems that are easier to evolve, observe and scale.

Athena

Enterprise Retrieval Intelligence Platform

A production-oriented retrieval platform designed for trustworthy enterprise knowledge access through optimized search, reranking, vector search and permission-aware retrieval.

SourceDocs →
01 — Problem

Enterprise search requires more than semantic similarity. Knowledge systems must retrieve accurate information while respecting permissions, reducing hallucinations and scaling across continuously growing document collections.

03 — Tradeoffs

Hybrid retrieval introduces additional infrastructure complexity but significantly improves retrieval quality compared with embedding-only search.

06 — Lessons Learned

Retrieval quality depends far more on disciplined retrieval pipelines than increasingly larger language models. Well-curated context consistently produces better reasoning.

Aegis

Trust & Decision Intelligence System

An enterprise AI governance platform focused on explainable reasoning, calibrated confidence estimation and policy-aware decision validation.

SourceDocs →
01 — Problem

High-impact AI systems require transparent reasoning before decisions can be trusted. Predictions alone are insufficient without explanation, confidence estimation and governance.

03 — Tradeoffs

06 — Lessons Learned

Enterprise AI succeeds when humans understand why a recommendation was made rather than simply receiving a prediction. Trust is designed through architecture, not generated by models.
