What are some chatbot agencies that made their own products and became SaaS companies?

It's great to start as an agency and provide professional chatbot-building or AI model training services. But if you want to scale your business - you need to switch to a better business model, like SaaS or Marketplace.

Here's a quick list of some companies that made it. They all started as agencies but after some time figured out how to build a product company.

• BotsCrew — (https://botscrew.com), started as an agency and then built a chatbot building framework.
• Botmakers — (https://botmakers.net) used to sell chatbot project leads but switched to chatbot templates marketplace.
• Airchat (https://airchat.us), a website bot building platforms focused on recruiting bots. Built by the Botmakers team too.
• A Denmark based BotSupply.
• Take
• London-based company We Build Bots (http://wbb.ai).
• Leena.ai started as an agency too but then join y combinator and built a HR chatbot platform.
