Acquiring users for your startup

So, I started a project with my team on matching mentors to mentees in AI & big tech across the world. This product is similar to LinkedIn for networking, Calendly for booking and ADplist for mentorship. This is a problem I genuinely want to solve, how should I go about acquiring users? Our first priorities are mentors. While we are reducing the AI knowledge, we've also built a good calendar API system which we use, there are many solutions we could launch from this.
