Hi Vengat -
Biggest advantage of being non-VC backed: You don’t have to only target billion dollar markets or huge growth opportunities. You can do things that don’t scale. You can do things with lower margins. You can make incremental (instead of only exponential) progress and reap the rewards. You can invest in serendipitous, hard-to-measure channels. You can do things you LIKE to do, instead of only things that maximize investor returns. You can focus on surviving for a long time, instead of growing as fast as possible no matter the cost. All of these are huge advantages.
Early-stage SaaS businesses with impressive marketing… unfortunately, I don’t maintain a list. Off the top of my head, I’ve liked stuff from https://textio.com, https://checkmyads.com, https://meetedgar.com/, and others I can’t currently find/recall (sorry!)
