Features

Spark is built around one idea: ideas mature at different speeds, and the platform you think in should let you choose how visible each one is, without ever making that choice permanent or all-or-nothing.

The Public Feed

Share an idea, a question, or a solved problem with the whole network. Public posts are evaluated by other users on merit - there are no follower counts, like counts, or other vanity metrics competing for attention. What rises is what other people found genuinely worth engaging with, not what was posted by whoever already had the largest audience.

Organization Workspaces

Scope a discussion to your team instead of the whole network. Organization workspaces give administrators seat management and workspace-level controls, while keeping that content out of the public feed entirely - a private layer for internal thinking, not a smaller version of the public one.

Trusted Circles

Some ideas aren't ready for an audience of any size yet. Trusted Circles let you hand-pick specific collaborators to develop an idea with, before you decide whether it ever becomes public. Access is enforced at the platform level: a Trusted Circle post is visible only to you and the people you've specifically invited - never surfaced in the public feed, never included in aggregate analytics, and never used to train any model. You can change a post's visibility later, but nothing already shared under a narrower setting is retroactively exposed by that change.

Direct Messages

Talk to another Spark user one-on-one, outside of any public or workspace context - for the conversations that lead up to a Trusted Circle invitation, or that never need to become a post at all.

Merit & Peer Verification

Contributions on Spark can be evaluated and verified by other users based on the substance of the work, building a transparent, evidence-based record of your thinking over time - expertise that speaks for itself, rather than a profile that speaks for you.
