First paying customers using Excel, now what?

Hi fellow IndieHackers,

This is my first post on here, so bear with me.

Together with a friend/ colleague of mine we are building a data-solution in the insurance business. In short, we are providing dashboards and insights for them to use.

Following the lean startup principles, we started validating our idea by talking to potential customers. After talking to these customers, we were able to land a ‘proof of concept’-project at one of those customers. We were able to use their data and providen them with tons of insights. We did this by using EXCEL (seems very basic, right?). The customer provided us with a datadump and we used different kinds of calculations in order to provide them with dashboards and insights. This allowed us to get to know the data and to make a first (basic) MVP, without trying to build a complex product already.

As of now, we want to land two or three more pilot-projects before actually productizing our excel.

So I want your help on this part. What would be the next step in productizing our basic excel-MVP? Should we hire a developper to code our calculations in some kind of program? Or are there some no-code solutions out there where we can build and productize our product relatively easy? Or do you guys (and girls) see any other options?

Thanks!
