Just continuously think about 1) how much value you product brings and why this is good for them 2) most sales reps are pretty mediocre at best 3) many other founders have gone through this before.
Companies who are potential early customers are also usually growth stage startups themselves (100-500 people) and want to help out other entrepreneurs. Email the founders to tell them what you're up to, and tell them you won't be a drag on productivity. A company like this almost certainly also has extra office space as they rent for growth.
Been using this for the past 4-5 months, ever since I saw a personal story of someone using it posted to HN.
It's been a game changer for me. I can WFH productively for the first time in my life, and have had 95% enjoyable experiences with the people on the other end of the chats thus far.
To those complaining about the pricing...they just started charging and I'm sure that's why it's not in the FAQ. Also, it's $5/mo, they aren't trying to get you hooked on something and then surprise you with $500/mo or something.
