Half-finished ideas, finished together — and paid out fairly.
Someone posts an idea they can't finish alone and attaches a bounty. Anyone can contribute design, engineering, testing or paperwork. Accepted work is weighed by hours multiplied by difficulty multiplied by impact, fingerprinted in the ledger, and paid its exact share of the bounty.

Featured builds
Ideas that need people, not permission
Anything from a million-dollar aerospace retrofit to a spec that needs adversarial review.
Low-drag regional wingtip
$1,000,000A retrofit wingtip for regional turboprops targeting 4% fuel burn reduction. Concept CAD exists; needs CFD validation, tooling plan and certification pathway.
Solar cold-chain esky for remote clinics
$85,000A 40L passively-insulated vaccine cooler with a small solar top-up. Prototype 2 works but holds temperature only 26 hours.
Open contribution ledger spec
No bounty yetA plain-English, auditable spec for weighting contributions across time, difficulty and impact so payouts are provably fair.
Wingtip variant: cargo conversion
No bounty yetA branch of the regional wingtip aimed at freighter conversions with different load cases.
