From documenting solutions to helping them last

Many community solutions save cities money or meet real demand. Few are documented well enough for anyone to see it.

  • Discover. Find solutions already working in cities, starting with waste.
  • Validate. Record the problem, the solution, the results and the value: to residents, to the city, and in potential revenue.
  • Grow. Connect proven work with funding, partners and new cities.

Some solutions grow through grants and public contracts. Others may be able to operate as businesses. C7 helps identify which path fits.

The communities that create a solution should share in its success.

C7 is testing this approach in Rio de Janeiro first, with partners it already works with.
