Ceramic

What Ceramic does

Ceramic (Ceramic, Inc.) is a Delaware-incorporated AI infrastructure company headquartered in Mountain View, California. Founded in 2024 by Anna Patterson, the company emerged from approximately one year of stealth development and publicly launched in March 2025 with $12 million in seed funding led by NEA and strategic participation from IBM, Samsung Next, Earthshot Ventures, and Alumni Ventures.

The company operates two core product lines. The first is a Web Search API that indexes over 40 billion web pages and returns results at approximately 50ms latency for $0.05 per 1,000 queries — pricing the company positions as materially below leading competitors priced at $14 per 1,000 queries. This product is targeted at AI agent developers running high-frequency search workloads, retrieval-augmented generation (RAG) implementations, AI chatbot builders, and verification/fact-checking workflows that require current web evidence. The second line is a proprietary AI model training stack achieving over 80% Model FLOPs Utilization (MFU) on NVIDIA B200 GPUs and supporting 96,000-word long-context training without performance degradation, marketed at approximately 2.5x the efficiency of open-source stacks and validated across NVIDIA, AWS, Coreweave, AMD, and Lambda hardware. In March 2026 the company launched Supervised Generation, a verification layer built on NVIDIA Nemotron 3 Nano that flags LLM outputs against retrieved web evidence with inline citations and confidence scores.

Ceramic runs a hybrid go-to-market combining product-led growth (free tier of 1,000 queries, self-serve sign-up, usage-based pricing that does not expire) with an enterprise field-sales motion offering custom rate limits, dedicated support, private data indexing, and SOC 2 Type II compliance with zero data retention. The company serves AI developers, RAG implementers, and enterprises building custom models, with named technical partners including Lambda and xAI.

Core offering

Ceramic develops AI infrastructure software comprising a Web Search API for LLMs and a high-performance AI model training stack. The Web Search API queries 40 billion+ web pages at $0.05 per 1,000 queries with 50ms latency, enabling AI models to ground responses in current information. The Training Stack delivers 2.5x faster training and 80%+ Model FLOPs Utilization on NVIDIA GPUs with support for 96,000-word long-context training without performance degradation.

Product overview

Ceramic is an AI infrastructure company offering two core product lines: a Web Search API and a Training Stack. The Web Search API provides low-cost web-scale search ($0.05/1K queries) enabling AI models to ground responses in current information. The Training Stack delivers high-efficiency AI model training with up to 96K word long-context support and 2.5x performance gains. The Supervised Generation feature (built on NVIDIA Nemotron 3 Nano) adds a verification layer on top, providing real-time fact-checking with inline citations. Enterprise features include private data indexing and dedicated support.

Broad incumbents

• Lambda: Lambda is a GPU cloud and AI infrastructure provider (NVIDIA HGX B200 partner). Both a validation partner of Ceramic and a broader incumbent offering AI training compute that competes for enterprise AI infrastructure spend.
• Anyscale: Anyscale provides a Ray-based AI compute platform for training and serving models at scale. Overlaps with Ceramic's training infrastructure offerings but serves a broader enterprise AI workload portfolio.
• Perplexity: Perplexity operates a consumer AI answer engine with proprietary search infrastructure. Comparable in the AI search domain but as a finished product rather than developer API; signals the end-market Ceramic's API serves.
• Together AI: Together AI is a broader AI cloud platform offering model training, fine-tuning, and inference infrastructure. Comparable to Ceramic's Training Stack business but with a wider portfolio including hosted models and inference APIs.

Direct peers

• Tavily: Tavily is a direct competitor offering a web search API purpose-built for AI agents and LLMs, with comparable positioning on real-time search grounding and agentic workloads. Raised $25M+ to compete head-to-head with Ceramic on AI search infrastructure.
• SerpAPI: SerpAPI provides a search engine results API used widely by AI applications for real-time web data. While broader than AI-specific, it serves overlapping LLM grounding and RAG use cases at different price points.
• Exa: Exa (formerly Metaphor) is a direct competitor providing a search API designed specifically for AI applications, with vector-based semantic search. Targets the same AI agent and LLM grounding use cases as Ceramic.
• Brave Search API: Brave Search offers an independent web search API with an emphasis on privacy and an independent index. Competitor to Ceramic's search API in the AI/LLM grounding market with established scale.
• You.com: You.com operates an AI-powered search API for developers building AI applications, with a focus on real-time web grounding. Directly competes with Ceramic's web search API offering for AI/LLM use cases.

Emerging players

• Jina AI: Jina AI provides open-source and commercial neural search infrastructure, including embedding-based search APIs for AI applications. Emerging competitor in the AI search infrastructure space with overlap on semantic/vector search for LLMs.
