What Graft does
Graft is a San Francisco-based AI infrastructure company, founded in 2021, that builds high-accuracy search infrastructure specifically designed for AI agents and large language models (LLMs). The company's core product is an AI search infrastructure platform offering retrieval-augmented and semantic search capabilities intended to power enterprise AI applications and API-based search services. It operated with a small team of 11–50 employees and offered its technology via an API surface aimed horizontally at enterprise AI platforms seeking to enhance their AI-driven search and retrieval functionality.
The company pursued a venture-backed growth path, raising approximately $14.5 million across three disclosed rounds between May 2022 and October 2023 from investors including Google Ventures, Radical Ventures, NEA, SV Angel, Essence VC, Formulate Ventures, and Alumni Ventures. Pricing, revenue model, customer names, and go-to-market channels were not publicly disclosed. In October 2025, Graft was acquired by You.com, with Graft's team and technology absorbed to enhance You.com's enterprise and API platform offerings for agentic and LLM-powered search.
Following the acquisition, Graft operates as a subsidiary of You.com, a strategic operating company focused on enterprise AI search. A separately branded "Graft" entity — a hybrid fitness center in Al Quoz, Dubai — is unrelated to the AI infrastructure business and should not be conflated with it.

Graft competitors and assessment
Company assessmentDirect peers
- Weaviate: Open-source vector database and AI-native search platform with hybrid retrieval capabilities for LLM applications. Directly competes with Graft in providing the retrieval layer behind RAG and AI agents.
- Pinecone: Managed vector database purpose-built for production AI applications including RAG and semantic search. The most directly comparable standalone AI search infrastructure vendor serving enterprise LLM and agent use cases.
- Qdrant: Open-source vector similarity search engine used for RAG, semantic search, and AI agents. A close direct peer targeting enterprise developers building LLM-powered applications.
- Vectara: Enterprise RAG-as-a-service platform providing hallucination-resistant retrieval and grounded generation for LLM applications. A direct peer in production-grade AI search infrastructure.
- Chroma: Open-source embedding database widely used for AI agent memory and RAG pipelines. Directly comparable as foundational retrieval infrastructure for LLM applications.
- Exa (formerly Metaphor): AI-native web search API optimized for LLM and agent use cases, emphasizing semantic/neural retrieval. Directly comparable as a specialized AI search provider for agents and LLM applications.
Broad incumbents
- You.com: Acquirer of Graft and a broader AI search and consumer/prosumer search engine. Directly comparable as Graft's retrieval infrastructure is now integrated into You.com's enterprise and API platform offerings.
- Elastic: Established enterprise search and observability platform with vector search and RAG capabilities via Elasticsearch. A broad incumbent whose AI search offerings overlap with Graft's enterprise positioning.
- Algolia: API-first enterprise search platform that has expanded into AI/vector search for LLM-powered applications. Comparable as search infrastructure serving developers building AI-enhanced product experiences.
Emerging players
- Tavily: AI search API purpose-built for LLM agents to retrieve grounded, real-time web information. Closely comparable target use case (AI agent retrieval) with a more agent-centric product framing.
