Great feedback, much appreciated! I'm familiar with Microsoft for Startups program and I'm still considering it, though currently it's not a priority. I agree with most of your thoughts above. Don't have experience with .NET-based Lambdas, though, so I don't have an opinion on that yet. As for what I'm building, well ... I'm building a comprehensive (read: large) and complex B2B enterprise SaaS platform focused on a particular multi-disciplinary scientific domain. I'm a solo founder and have technical (and research) background, including software development and IT architecture experience.
