About

PortMem is built by one person who has sold into and studied this problem for two decades. The first two hires at close: a founding engineer and an enterprise GTM lead.

For twenty years I sold enterprise technology into regulated buyers at Huawei, Cisco, and Google. I watched the same failure mode again and again as AI arrived in these accounts: systems retrieving the deprecated 2017 policy over the active 2024 one, generating confident answers from stale sources, and offering compliance no way to audit what had been used.

The standard answer was "add more LLM". More agentic loops, longer context windows, fancier rerankers. None of it solved the actual problem, which was that retrieval was being optimized for similarity when regulated buyers needed retrieval optimized for what is currently in force.

I wrote four arXiv papers to fix this from first principles. PhaseGraph calibrates vector and graph scores. BridgeRAG handles multi-hop. RegimeRouter picks the right strategy per query. CAR formalizes the controlling-authority problem and proves it is a different mathematical object from semantic relevance. Those four papers are the engine. PortMem is the product built on them: the system of record for AI work product.

Background

20 years in enterprise sales

Huawei, Cisco, and Google. I have sat in the procurement meeting where a wrong citation kills the deal. I know what compliance officers read for and what they flag.

Founder, ARClogic

Built and ran an enterprise software company before this one. The patterns that break in production are the patterns PortMem is designed to prevent.

Four sole-authored arXiv papers

Each one fixes a specific failure mode in retrieval over regulated content. Datasets, scoring code, and reproducibility memos are public. See the research.

Columbia MBA · BS Electrical Engineering

Trained on both sides of the table. Engineering rigor on the product, business literacy on the GTM.

Why now, why me

Three things converged in the past 18 months. Frontier LLMs stopped hallucinating when handed a single relevant passage, so the bottleneck moved from generation to retrieval. The EU AI Act made citation accuracy a legal liability, with transparency duties and GPAI fines applying from August 2, 2026. And the research to solve regulated retrieval became tractable.

I sat at the intersection of all three: an operator who had felt the pain, a researcher who could write the papers, and a salesperson who knows what regulated buyers will pay for. PortMem exists because the same person did all three.
