SHOW IH: How I built my new app in two weeks and got $35 in revenue in the first month

Ok, I'd split it up into three categories: Organic/viral wins, repeatable wins, and one-off wins. Bear in mind I don't know that much about your product and/or customers.

Organic/Viral wins:

• Create a free/heavily discounted version which inserts "created by {{ your logo }}" as a watermark or splash screen into the preview videos.
• Give podcast producers 1/3/6 months free access if they do a shout out for your product on their podcast and social media accounts.
• Create a landing page ASAP so you can track and retarget potential customers.

Repeatable wins:

• Set up an automated cold email service like LemList.com and pay someone from UpWork to manually scrape the contact details of various potential customers. They are easy to find (podcasters want to be contacted generally) and this could be really effective.
• Publish case studies and articles on the effectiveness of podcast marketing. Share them on groups/forums.

One-off wins:

• Do partnerships/cross-promotion with other people who are selling to podcasters.
• Share and contribute on FB groups, forums etc

Good luck!
