Pinecone Systems, Inc. is a Delaware-incorporated managed vector database company founded in 2019 by Edo Liberty, formerly head of Amazon SageMaker's research lab and a Yahoo Research engineer.
Pinecone offers a fully managed cloud-native vector index with sub-100ms similarity search across billions of embeddings, hybrid sparse/dense retrieval, namespacing, metadata filtering, and serverless and pod-based pricing tiers. The platform powers retrieval-augmented generation (RAG) workloads, semantic search, recommender systems, and de-duplication pipelines for thousands of AI-native startups and enterprises.
Operational headquarters are in New York City, with engineering hubs in Tel Aviv and remote across the US and EU. Pinecone raised a 100 million US dollar Series B led by Andreessen Horowitz in April 2023, valuing the company at 750 million US dollars and bringing total funding above 138 million US dollars. Customers include Notion, Gong, Shopify, Microsoft, and a long tail of LLM application builders.
Pinecone Systems, Inc. is a Delaware C-Corporation with its registered agent at the Corporation Trust Center in Wilmington.
Pinecone is the canonical AI-infrastructure Delaware C-Corp, with a capital stack and structural choices that have become template for vector-database, embeddings-pipeline, and inference-orchestration peers. The financing pattern: pre-seed and seed SAFEs in 2019-2020, priced Series A led by Menlo Ventures in 2021, priced Series B led by a16z in 2023 at 750 million US dollar post-money.
Each priced round issued a new series of convertible preferred stock with 1x non-participating liquidation preference, weighted-average broad-based anti-dilution, pro rata rights, and standard NVCA voting/IRA/ROFR documentation.
The option pool was refreshed at each round, with top-up costs paid pre-money by existing common holders - a typical cost of roughly 8-12 percent dilution per round.
The 409A valuation is refreshed annually and after each material round, with common stock priced at a 25-35 percent discount to the latest preferred for a Series-B-stage company, allowing the company to grant ISOs at strikes that are competitive in the AI-engineering hiring market.
Pinecone's product is partly open: the company maintains an open-source pinecone-client library under Apache 2.0, contributes to LangChain and LlamaIndex ecosystems, and publishes research, but the core indexing infrastructure - the proprietary vector engine, the multi-tenant control plane, the autoscaling logic - is closed source.
The Contributor License Agreement governs external contributions; CIIAA governs employee work. Pinecone Systems, Inc. owns USPTO trademark registrations on the wordmark and the pinecone logo.
Delaware is the right legal home not just because every VC requires it but because the eventual exit - whether IPO or acquisition by a hyperscaler - will be cleaner from a Delaware C-Corp than any alternative; NVCA model documents assume Delaware default rules, and the Chancery court has decided every preferred-stock dispute imaginable.
Use post-money SAFEs for pre-seed and seed checks under roughly 5 million US dollars total - they convert at the next priced round at the better of the cap or discount. AI-infrastructure rounds at the seed stage have inflated significantly, so founders should model SAFE conversion at multiple Series A scenarios before stacking too many.
Pinecone followed a clean SAFE-to-priced-round path: SAFEs in 2019-2020, priced Series A in 2021, priced Series B in 2023. The priced-round threshold matters because preferred-stock terms (liquidation preference, anti-dilution, board seat) only kick in at the priced round, and SAFE holders inherit those terms at conversion.
Every institutional VC writing an AI-infrastructure check requires Delaware. The Chancery court's preferred-stock case law is decisive on liquidation preference disputes - which matter more in capital-intensive AI companies because preference stacks can grow large. Section 1202 QSBS treatment requires a domestic C-Corporation, which Delaware is the natural default.
Wyoming's LLC privacy is irrelevant once an institutional cap table is filed, and a pre-Series-A redomicile to Delaware costs legal fees and resets the QSBS five-year holding clock.
The standard pattern is to release client libraries, SDKs, and tooling under permissive licenses (Apache 2.0, MIT) to maximize adoption, while keeping the core infrastructure - the indexing engine, the multi-tenant control plane, the autoscaling logic - closed source.
A Contributor License Agreement governs external contributions to the OSS clients, ensuring the company can relicense if commercial pressure requires it (HashiCorp BSL example). All trademarks and core IP are owned by the Delaware C-Corp.
Four-year vesting with a one-year cliff is universal. Double-trigger acceleration on change of control - acquisition plus involuntary termination within 12 months - is the standard Series-B term sheet from a16z, Sequoia, Benchmark, Founders Fund, and other major leads. Single-trigger is rejected as disruptive to acquirer retention. 83(b) elections within 30 days of restricted stock issuance are mandatory.
Repurchase rights at fair market value remain in place through and beyond the Series B for any unvested shares of departing founders.
