My day job for years has been a developer at early stage startups, so I'm fully aware of the amount of sheer grinding involved in customers. And the years of iteration to achieve something that resembles product-market fit. I've incorporated some of these tricks we've used as I've learned them from our teams.
Some of the low-cost things I've tried, with varied success:
- Writing to influential bloggers, - Social media grind - Adwords
But ultimately these are side projects. Can't pound the pavement in the middle of work.
