A managed vector database and semantic search API

A Pinecone-style platform that lets developers index millions of embeddings and run low-latency semantic search behind a clean API.

The challenge

Teams wanted to add semantic search and retrieval-augmented generation (RAG) to their products without standing up and operating their own vector infrastructure. They needed a simple API, predictable latency at scale, and an SDK their engineers could adopt in an afternoon.

Our approach

We designed the API surface first — index, upsert, query — then built the storage and retrieval layer to meet a strict latency budget. A dashboard and SDK were built alongside the API so the developer experience was tested from day one, not bolted on later.

What we built

  • REST API for creating indexes, upserting vectors, and querying
  • Low-latency approximate-nearest-neighbour retrieval layer
  • Client SDK and quickstart so teams integrate in minutes
  • Usage dashboard with API keys, metrics, and billing
  • RAG reference implementation wiring search into an LLM

The results

  • Consistent sub-120ms queries across millions of vectors
  • End-to-end developer onboarding in under 15 minutes
  • Reusable RAG pattern adopted across multiple downstream apps
  • Clean separation of API, storage, and dashboard for easy scaling

"The API and SDK felt production-ready immediately. We shipped semantic search into our product the same week."
