SecondStack gives an entire organization access to AI without handing its data to third-party clouds.

The platform ships three end-user workspaces โ€” Chat for everyday work, Code for engineering teams, and Agent for automation โ€” running on top of an enterprise LLM gateway that connects to the model providers you choose (OpenAI, Anthropic, Google, and others). Platform and security teams manage everything centrally: who can use which models, what each team spends, and where data lives โ€” inside your own infrastructure.

Because SecondStack is self-hosted, prompts, files, and knowledge bases never leave your environment. For teams that prefer not to operate it themselves, a managed deployment run by the SecondStack team is also available.

Pricing is not per-seat, so rolling AI out to the whole company does not multiply the bill. Deployment and operations are backed by an ISO 27001-certified implementation partner.

BigSpy Reviews

  1. A game-changer for finding winning products ๐Ÿš€

    I've tried several ad spy tools, but BigSpy offers the best value for money. The database is massiveโ€”especially for Facebook and TikTok ads. It saves me hours of manual research and helps me spot trending products before the market gets saturated. If you run a dropshipping business or manage paid social, this is a non-negotiable part of the tech stack. Highly recommended for the "Ad Ideas" feature alone.
