Hey, Jonny! 
I asked myself this question many times in the past, and this is what I think about it today. If I had to start a new business knowing what I know today, I would do my best not to raise capital from traditional VCs. With more alternatives (Indie.VC, Tiny Seed, Earnest Capital, etc.) in the market, you can build a big business without giving away huge chunks of your company or having to buy into the arbitrary VC game of funding cycles.
VCs have their place for sure, and I’m lucky that I have great ones on board, but it depends on what your long-term goals are and what success looks like to you.
I would definitely do an accelerator again, especially Techstars. The network is super helpful, and it delivers on the promise of being a lifetime partner. And, of course, the Amazon credits come in very handy
