What Superlinked does
Superlinked is an open-source infrastructure company building the Superlinked Inference Engine (SIE), a Kubernetes-native inference cluster designed to serve specialized AI workloads — embeddings, rerankers, OCR, and entity extractors — on customer-controlled cloud infrastructure (AWS, GCP, Azure) or air-gapped environments. The platform exposes three primitives: encode (text/images to vectors), score (reranking), and extract (structured entities), shipping 85+ pre-configured open-source models and integrating with the major AI frameworks (LangChain, LlamaIndex, Haystack, DSPy, CrewAI) and vector databases (Chroma, LanceDB, Qdrant, Weaviate). The company was co-founded by Daniel Svonava and Ben Gutkovich, is headquartered in San Francisco with engineering offices in London, Budapest, and Tel Aviv, and is SOC2 Type 2 certified under an Apache 2.0 license for the core engine.
The business model centers on a free open-source core paired with an upcoming managed inference tier and an "inference grant" program offering free hosted capacity for selected projects — no commercial pricing has been publicly disclosed. GTM is dual-track: product-led growth via GitHub distribution (2.1K stars on superlinked/sie) and developer documentation, layered with enterprise field sales for regulated, compliance-bound, or air-gapped deployments. Target customers are enterprise AI platform teams building search, RAG, and agentic applications, alongside regulated verticals (financial services, healthcare, legal, government) with data residency requirements.
Superlinked has raised over $12M across multiple rounds, anchored by a $9.5M seed in March 2024 led by Index Ventures with participation from Theory Ventures, Samsung Next, Tomasz Tunguz, and a broad syndicate including Sequoia Scout, MMC Ventures, and Episode 1. The company employs 11–50 people (24+ post-seed) and positions its core technical differentiation on a cluster-wide pool-then-batch architecture that achieves 89% GPU efficiency versus ~51% for route-then-batch competitors, yielding up to 50x cost reduction versus managed APIs for embedding ($0.50 vs $20 per 1B tokens) and reranking ($8.50 vs $87 per 1B tokens) workloads.

Product offeringCore offering
Superlinked provides the Superlinked Inference Engine (SIE), an open-source Kubernetes-native inference cluster that serves 85+ pre-configured open-source models (embeddings, rerankers, OCR, and entity extraction) on customer-controlled infrastructure (AWS, GCP, Azure, or air-gapped). The platform exposes three primitives—encode, score, and extract—behind an OpenAI-compatible API, enabling enterprises to replace per-token managed API costs with fixed compute, achieving up to 50x cost reduction for embedding and reranking workloads.
Product overview
Superlinked offers the Superlinked Inference Engine (SIE), an open-source inference platform for self-hosting specialized AI models. SIE is a Kubernetes-native cluster that serves 85+ pre-configured models (embeddings, rerankers, OCR, extraction) behind a unified API with three primitives: encode, score, and extract. The platform enables enterprises to replace per-token API costs with fixed compute infrastructure, achieving up to 50x cost reduction. SIE integrates with major vector databases (Chroma, LanceDB, Qdrant, Weaviate) and frameworks (LangChain, LlamaIndex, Haystack, DSPy, CrewAI) to power search, RAG, and document processing pipelines.
