.NET Blazor for a New Startup?

I'm creating a B2B web-based SAAS for small to medium businesses. It's going to be a heavy SPA with .Net Core micro-services. I've always been a .Net/C# guy and I'm extremely impressed with the new Blazor webassembly SPA framework. After some heavy testing it's 100% capable as a front-end tech. However I worry that there might not be enough of a C# talent-pool willing to be a co-founder or early employee. It seems like 99% of startups these days use one of the Javascript frameworks. It's a bummer for me, but should I consider switching my dream stack to Typescript and React or some other framework? Typescript at least has made JS a little more palatable to me.
