Categories Cello serves
The B4 Index places Cello in one category. Each category page lays out the build-versus-buy considerations for that decision.
The B4 Index scores every software category on two axes, strategic differentiation and AI feasibility, to
classify it Build, Buy, Bridge, or Beware. Vendor facts here are independent of that call. See the full
methodology.
