Building the product is not the hardest part. The hardest part is generating the sales. What strategy does a startup need to follow to get their first 100 customers?
If your product is B2B I highly suggest creating a targeted outbound campaign. You can do it all on a super cheap budget too. You can setup a G Suite/Gmail account for $5 a month and use a tool like Mailshake for under $20 a month and you have a few different options for getting data/emails!
