Provides backend functionality, such as data processing or authentication, via simple REST or GraphQL APIs to other developers. This model leverages high-margin code assets and requires no complex frontend design, appealing to B2B customers who value integration ease over visual interface.

Uses smart forms to generate legally compliant contracts, privacy policies, or NDAs tailored to specific jurisdictions. This high-trust vertical commands premium pricing and faces lower competition from giants due to the complexity and nuance of legal requirements.
