Zep AI vs Extend
Side-by-side comparison of AI visibility scores, market position, and capabilities
SF AI context engineering platform providing agent memory and Graph RAG for persistent LLM recall across sessions; YC W24 $3.3M reaching $1M revenue competing with Mem0 and LangChain for AI agent memory infrastructure.
About
Zep AI is a San Francisco-based AI context engineering platform — backed by Y Combinator (W24) with $3.3 million raised from Engineering Capital, Step Function, and investors from Vercel and Google — providing AI application developers with agent memory, graph-based retrieval, and context assembly tools that enable AI agents to remember user history, recall relevant facts from previous interactions, and maintain long-term persistent state across multi-session workflows. Founded in 2023 and generating $1 million in revenue by June 2024 with a 5-person team, Zep AI addresses the fundamental challenge in production AI agent deployment: LLMs are stateless (each conversation starts fresh with no memory of prior interactions) while users expect agents to remember preferences, past decisions, and conversation history across sessions.
San Francisco AI document processing using LLMs for enterprise data extraction from invoices, contracts, and forms; $17M Innovation Endeavors and YC-backed at multi-million ARR serving Brex and Square cash-flow positive.
About
Extend is a San Francisco-based AI document processing platform using large language models to provide accurate data extraction and document understanding for enterprise workflows — turning unstructured documents (invoices, contracts, medical records, financial statements, onboarding forms) into structured data at the accuracy and cost level that manual processing and traditional OCR cannot match at scale. Backed with $17 million raised in combined seed and Series A funding led by Innovation Endeavors with Y Combinator, Homebrew, and angel investors including Adobe's CSO and Vercel's CEO, Extend reached multi-million dollar ARR and cash-flow positive status serving customers including Brex, Square, Checkr, and multiple Fortune 500 companies.
