Have you seen his comments on LinkedIn? Doesn't seem like the type of guy who's honest. He kept covering behind "send an rfq" or "sign an nda" or "we're a business not a newspaper" instead of proving anything. Also, here's some products that weren't delivered: - https://burstlive.io/ - https://stingbase.com/ - https://venturebonsai.com/ - https://shadowcapital.com/ - https://kaseygroup.com/ - https://www.definancetechnologies.com/
All links were obtained from the CEO's LinkedIn page. The last one is definitely a scam. They ask for your money and promise that their magical algorithm will give you profit.
The first one has fake "featured in", Privacy Policy does not exist and almost all those websites were using Wordpress (perhaps made by the same guy?).
I don't think you actually did research on him.
Any examples of scammed people? lawsuits?
Failed startups aren’t scams by default. You need someone who not only lost their money but lost it because they were misled.
