Genuinely non-snarky question. It looks like a standard calculator and conversion app, and it looks like most of the implementation I could imagine being in a calculator app is already done. Why would you even think of raising funds? You thought it was a good idea to write the blog post, so it obviously crossed your mind.
Because he went through an accelerator. He'll be told for months that the demo day and the pitch will be super-duper important, because investors.

As for the demo day, we were told early on that it's a big thing, but it's unlikely that we'll be discovered then. I got in touch with a pretty great investor who's kinda interested, but I think they're way out of our league now (series A/B level), so we'll wait. Also, on that day we initiated a B2B deal which just might turn out to be what we need at this stage (we're building a prototype now).
I love the Berlin-SV comparison and your conclusion!
