To probe further, we ended up doing a lean startup style "customer discovery" interview process. We ended up talking to 35+ people in the SMB space which validated some of our initial hypothesis but also not giving a strong signal on the top pain point.
So, what are the challenges you face? I would love to hear how you are dealing with these challenges. If you prefer to shoot me an email, you can find my email on my profile.
Thanks in advance!
