    While basic features are user-friendly, leveraging advanced functionalities like managing Kubernetes can come with a steep learning curve for new users.

Our product has a lot of power features and is built to handle very advanced forms.

What's the story behind your product?

DocSpring's answer:

I used to work at a payroll company (Gusto). We had built a similar in-house tool for filling out tax forms. I then built the first version of DocSpring (formerly named FormAPI) while I was living in Thailand. I built it to automate the filling out of visa application and visa extension forms, but realized that it could also be used for tax forms, real estate contracts, and any other kind of fillable PDF form.

DocSpring's answer:

  • SaaS services serving customers in the real estate, insurance, finance, and legal industries, among many others.

    Great post. I've spend a lot of time reading through the PDF specification over the last ~5 years while building DocSpring [1], and I still feel like I've barely scratched the surface.
