good ideas are nice. working ones are better.
  • Who does what

    seven42 owns the apps, the product direction and the accounts. 21Labs designs and builds them. One login opens all five, and each one does a single job.

  • Why we build them

    An agency that builds software for other people should ship and run its own. These five apps are the same Discover, Craft, Measure, Repeat cycle we use with clients, applied to products that real people open every day.

  • Try one

    Every app is free to start at its own address. Pick the one closest to a job you have.
