Tips to land an interview at Stripe (PM)

I've had little luck reaching landing an interview for a PM role at Stripe. Reaching out to their recruiters ( five of them ) on LinkedIn resulted in nothing more than being politely redirected to the Stripe application page. I'm intent on joining Stripe because my aim is to join a company that helps other businesses earn a dollar. I have a side-hustle that leverages the Stripe SDK for payments, and was incorporated with Atlas. I believe they legitimately made it easier for me to start a business. Does anybody at Stripe have advice on what skills/attributes/experience I can build up to get some traction? I painfully realize, and understand, that being a PM at MSFT probably counts against me. However, I do have software development experience, a CS degree from a top institution, and a side business that leverages the Stripe payment platform. Is there anything else I can do, or is direct work experience from a payment platform, like Square, a prerequisite?
