In hindsight, these are the things I wish we had done differently at Spectrum.
It's better to have 100 true fans who love the product than 10,000 barely interested users.
Do way more marketing and sales than you think you need to do.
Tell your story, it differentiates you from the big players in a crowded market
Launch before you think you are ready and then again and again and again.
Stick with the minimum viable technology setup until you feel product-market fit. You will know in your heart if you have it.
Talk with your users, they should be your guiding star.
