I am building Polotno SDK (https://polotno.com/). It a mix of SaaS and paid javascript library and react components. It is a design editor that you can integrate into your web app. From the first paying customer it took around 1 year to get 2000 MRR. And I spent around 9 months on making first version before the first paying customer.

It took me a very long time to find the idea of SDK. Previously I was thinking only about B2C cases. B2C market is already VERY crowded with Canva and million of its competitors. But B2B market was almost empty when I started.
