    For years, enterprises have been promised useful tools for application modernization, digital product development, and no-code/ low-code. But these promises have not been kept. Instead, enterprises got a thousand disjointed point solutions, that don't scale, and ended up captive to proprietary languages and fixed vendor solutions. Enterprise customers face an urgent need to modernize, with ~80% of IT budgets locked up in maintaining old legacy systems. They demand fast integrations with simplified, lower-cost implementations. There is tremendous competition. Securing market share is hard enough. Growing is significantly harder. Enterprises need to build complex omnichannel digital products that provide an excellent user experience. People are sick and tired to be locked into proprietary programming languages, with compounding vendor fees and add-ons. Large enterprises need the freedom to build and extend easily their digital platforms.
