Zoho may be one of the most underrated tech companies. The 23-year-old company, which at this point offers more than 45 products, has never taken outside funding and has no ambition to go public, yet it’s highly profitable and runs its own data centers around the world. And today, it’s launching Catalyst, a cloud-based developer platform with a focus on microservices that it hopes can challenge those of many of its larger competitors. The company already offered a low-code tool for building business apps.
