Zapier is definitely one of the most successful ones, although, I'll take anything about market-size and valuations with a grain of salt, especially considering these are pre-2022 numbers.
The beauty with products like Zapier is that they have a very clear idea of what you can do with it: "connect product X with product Y".
Many of the other no-code/low-code products are very much open-ended and leave a lot of freedom to the user, on paper this sounds great, but when you try to explain your finance admin how they can build an app that will reduce 90% of their workload, they just got no idea what to do with it and keep on doing manual work.
