Why this helps
Partnership ideas can lose momentum when the rationale and possible value need to be pieced together later.
- Keep the partnership rationale in view
- Organize mutual value and assumptions
- Make the first proposal draft easier to review
Setup
Build it in a few focused steps.
- 1Connect Slack and Gamma to Notis once through the portal.
- 2Create a new automation called Partnership Proposal Draft.
- 3Write one plain-language instruction asking Notis to create Gamma proposal slides from relevant partnership discussions, covering shared goals, possible value, assumptions, and open questions.
- 4Pick the Slack channel message trigger and a channel for run reports.
- 5Test with one real partnership discussion and review the proposal before sharing externally.
Questions about this workflow
Will Gamma send the proposal to the partner?
No. The action creates a Gamma generation for review; you decide whether and how to share it.
Can the draft include assumptions?
Yes. Ask Notis to label assumptions clearly so the team can validate them before using the proposal.
