Once your partner approves. [How Activation works](https://www.eleenai.com/en/platform/activation) 1. **[01]** — A result — The overlap you found, as EleeNIDs, still inside the room. 2. **[02]** — Partner approval — Your partner approves the audience before it can leave the room. 3. **[03]** — Your channels — It reaches Meta, Google and others as hashed IDs. [ 05 / 05 ] FAQ ## What your partner sees. And who pays, custom questions and how long a room lasts. ### Does our partner see our customer list? No. Each side's data stays where it is. Only aggregate answers come out, with small groups held back. ### Does our partner need to pay? No. The side that starts a collaboration pays, and partners join free. ### Can we ask our own questions? Yes, within the privacy terms both sides agreed. Each custom question is checked against them before it runs. ### How long does a collaboration last? Until it's completed. It can be paused along the way, and every result expires on the date set in its terms. Something else? Ask the team directly.
