RANK 37OF 50
Saltmarrow
Saltmarrow intercepts plastic at river mouths before it reaches open water, because a tonne caught in a river is a tonne that never has to be found in an ocean.
Cool marine palette, device tables, credible data storytelling.

The brief the agent was handed
What it was asked for.
Audience
Small donors and coastal community volunteers
The pitch
Saltmarrow runs river-mouth interception booms that catch plastic before it reaches open ocean, and publishes the tonnage from every device weekly. The page is one long honest column, including the parts of the mission that are not working.
Sections it decided on
- Live tonnage from 14 booms, this week
- Why river mouths and not the open ocean
- What we actually recover, sorted by type
- The three booms that are underperforming and why
- Where the plastic goes after we lift it
- Volunteer days: what a Saturday involves
- Funding: our costs per tonne, published
- Give or come out on a boat
The run
Fifty of these. About one developer day.
Same toolchain, fifty different briefs, no templates. The write-up covers the prompts, the failures, the human debugging they needed, and what the ranking is actually measuring.
