We’re thrilled to announce that TopK has raised $5.5 million in seed funding to build the world’s first AI-native, true hybrid search engine for enterprise. This milestone is backed by Earlybird, KAYA, Irregular Expressions, and a group of exceptional angel investors — who share our conviction that search must evolve to meet the demands of modern AI-driven applications.
The Search Landscape Is Changing
The explosion of large language models like ChatGPT has accelerated enterprise demand for vector databases—and exposed the limits of legacy search systems. Today’s companies face:
- Fragmented infrastructure: Piecing together multiple databases, APIs, and ranking layers.
- Performance bottlenecks: Traditional search engines struggle to deliver low-latency hybrid results at scale.
- Rigid ranking: Little to no flexibility in tailoring results to domain-specific needs.
TopK was born to address these gaps, enabling developers and AI agents to search both structured and unstructured data—with lightning speed and deep control over relevance.
True Hybrid Retrieval, Unified in One Engine
At the heart of TopK is our hybrid retrieval approach, which seamlessly blends:
- Vector search (semantic embeddings)
- Keyword matching (precise keyword filtering)
- Advanced filtering & ranking (domain-specific tuners)
By unifying these capabilities under one roof, teams can fine-tune their query pipelines, optimize ranking strategies, and serve production workloads at web scale—no stitching together of disparate tools required.
