My wife was pregnant and tired of doing cold video outreach for our recruiting business, so I wrote a python script that took her best video and just spliced in audio of her saying different people’s names and LinkedIn profiles.

To hide the lips not matching the audio, she did a little wave that covered her mouth at just the right time.

It ended up working so well it generated us over $500k in new business

And I ended up turning it into a SaaS (https://dopplio.com)
