Vespa is the big-data serving engine that spun out from Yahoo in October 2023 and raised a $31 million investment from Blossom Capital in November 2023. The company provides an open-source platform for real-time, low-latency data serving, including full-text search, vector search, and machine-learned model inference. Vespa's technology was originally developed at Yahoo to power search and personalization across its properties, and it now serves a range of enterprises that need to combine structured, unstructured, and vector data in a single query.
As of mid-2025, Vespa has not disclosed its revenue or headcount, but the company has stated it is focused on growing its customer base and product capabilities. The platform is used by companies such as Spotify, Wix, and others for applications like recommendation systems, e-commerce search, and content personalization. Vespa competes with other search and vector database providers, including Elasticsearch, Solr, and Pinecone.
The company's open-source model and Yahoo heritage give it credibility in the enterprise market, but it faces challenges in differentiating itself in a crowded space and in converting open-source users to paid customers. Vespa has not announced any additional funding rounds since the 2023 Series A, and its financial trajectory remains opaque. The company's leadership includes CEO Jon Bratseth, who previously led the Vespa team at Yahoo.
