Sparcle careers

Sparcle builds AI that enterprises can run inside their own walls.

Bolt is a desktop workspace for Windows, Mac and Linux. One hotkey opens search, files, notes, a browser and 80+ utilities that run on your machine with no model call. When Bolt's AI runs, it masks secrets and personal data before anything leaves the device. Bolt is free for individuals and needs no account.

Aeira is self-hosted enterprise search that checks each person's permissions before a document can be retrieved, so AI answers only use what that person may see. Enterprise deployments run on your infrastructure, with your own models and keys.

Every consequential action is recorded in a signed audit trail that an auditor can verify offline.

We are a small founding team in Sunnyvale, California, working on privacy, security and trust for AI at work. Founded in 2025. Download Bolt: sparcle.app/download
