i was hesitating to answer because i did not know what was the product - now i know.

it looks like a niche product for developer community. what i would try:

* write content around how to create web form in different language + add to each article reason why they should use your saas instead

* create a youtube video that would show how to use the product, focus on researched keywords, e.g. how to make a secured web form

* join slack and facebook group communities

* try to promote your tool on producthunt, not because of the sales - but to gather the feedback

* there are many great products out there and some of them have better product market fit + marketing = what i want to say it is more like a marathon than a sprint

good luck!
