This is very interesting, thank you for sharing. I haven't been doing FHE for a few years and I'm sure things are progressing rapidly. The last I was toying around there were some blockchains that were trying to allow for distributed computation for trusted computing. The overall outcome was that it wasn't ready and I was going to wait a bit to try again.
Is this closer to Fully Homomorphic Encryption (FHE) or partial?
Are you guys currently providing this as a SaaS or hostable solution? I am interested in standing it up and offering it, but I think it's important to know if anyone else is already working on that and in what markets.

HEVEC uses partial homomorphic encryption, not FHE.
It supports only the operations needed for an encrypted vector database (search, insert, delete, etc.), which keeps performance practical.
Implementation details are in our paper: https://arxiv.org/abs/2506.17336
Happy to elaborate if helpful.
