It sounds like a perfectly reasonable idea, and I would be happy if it actually works out! However, I must admit that HR portals are rabbit holes that looks good on paper, but then fall into one of two problems: chicken and egg, or garbage data. You need to have very clear strategy of how both sides of the job market are encouraged to adopt a new "empty" platform, while making sure that job listings are actually clean, truthful, and relevant. Are you saying that founders will input the resumes? It sounds like a lot of work, and not something I'd expect a person with a failing project on hand be able to do.
