Think Out Of The Box

An interesting discovery was made when someone online expressed a need for one of the tools provided by RapidTables, but they were looking for an embeddable widget, which RapidTables does not offer.

This presents an idea: why not build something similar to RapidTables but with all calculators embeddable?

To validate this idea, one could start with Shopify, cold email shop owners, and inquire if they would be willing to pay for such a service. If the response is positive, a SaaS version of RapidTables could be developed!
