3. Founding Story
The story begins before the company. Bob van Luijt describes encountering word embeddings and GloVe around 2015–2016. The key insight was that machine-learning embeddings could represent semantic relationships numerically: if meaning could be represented as vectors, software could search by meaning rather than only by exact words. [4][36]
The early concept was influenced by semantic-web ideas, graph representations and the practical problem of naming and finding objects across software systems. The team tested whether context could be represented through embeddings and whether data objects could be stored and retrieved directly in vector space. [4]
By late 2018, the project entered a Dutch startup accelerator. In 2019, SeMI Technologies was formed around the open-source project. The team initially explored a broader graph/semantic-data concept, then deliberately doubled down on NLP, embeddings and vector storage as the technology's value became clearer. [4]
A major turning point came as transformer models and then generative AI made embeddings, semantic retrieval and RAG mainstream. Weaviate's open-source community and developer adoption gave the company a distribution base, while managed cloud services supplied a monetization path. [5]
