What about a Primer for corporate learning?

Hi,

I am a Brazilian entrepreneur specialized in gamification and corporate education. I'm on my 2nd startup and I have created Lira Edu, a B2B SaaS for corporate training and education.

I started the project in December last year. In February of this year I have launched a pilot training program with my app in a facilities company. They were having problems with the traditional training model ( long videos, power point workshops ) so they needed a solution for it.

The pilot was a success. We had massive engagement of the employees and the knowledge retention was very good. My client agreed to a 1 year contract so we would train all the +1k employees of the company.

We started with a training about covid-19, teaching what is the coronavirus, the covid-19, symptoms, prevention and how to detect fake news ( the image prints above are the ones of the covid-19 training, I'm sorry they are in Brazilian Portuguese ).

My point is, I am doing good with this client and I am convinced that there is a niche for this product, but at the same time, I don't think I can consider that I have validated my idea because of this one case with this client, can I?

I am struggling to get new clients but I don't know that is because I am a tech / product guy with some difficult in sales or I need further validation.

What do you think?
