About Matthew Koen
Customer and product obsessed engineer, engineering manager, and account & partner manager/technical customer success lead. Have led multiple products from 0 to 1, from product design & engineering to sales to account management, leading to millions in revenue generated. Specialties include Voice AI, deep algorithmic design for LLMs at the application layer (to make LLMs actually work for enterprise, at scale), and technical customer success, specifically for AI. Recent Highlights: — Led a team of 3 engineers to design, build, and deploy Kafka (usekafka.com), a generalist AI agent, which reached SOTA on benchmarks such as GAIA (77% Level 3), beating OpenAI Deep Research, Manus, and more by over 20%. — Managed and scaled multiple customers by 1.5-3x month over month. Directly responsible for $XM ARR generated. — Designed and built propriety Planning MCP for non-thinking LLMs (resulting in similar performance to thinking counterparts on benchmarks, allowing for far cheaper, faster, more reliable inference for deep thinking use cases). — Helped build and design proprietary programming language and framework for quickly building high performance, deterministic conversational flows with LLMs (used by Fortune 50 and beyond in production conversational agents). — Designed, built, deployed, and maintain a low latency AI Voice server, serving millions of minutes every month. — Designed and implemented a proprietary method of LLM tool calling during Voice AI conversations, resulting in a 7% increase in accuracy, and the ability to use cheaper LLMs without loss in quality. Currently building conversational and generalist agent platform @ Brainbase. In my free time I enjoy surfing, riding mountain bikes, and playing guitar and piano w friends
