Impact Venture Capital / fix everything for a start
There's one fact that may ruin absolutely everything including their reputation if it exists.
If a website has pages with 404 errors, it means that no one cares about it. It means there is no person who would look after it. It means there are no updates and nothing new. It means then you have nothing to do here.
I looked through their small portfolio that wasn't even well-structured and designed. Each time I want to read more about any project, it redirects me to a page that doesn't exist. Or maybe used to exist. Who knows.
I don't think I have to continue reviewing it. Yes, everyone makes mistakes. But not so obvious ones.
