Could you do this 20 times as a custom services consultant and then identify the most important and valuable ask from your clients and then productize that as software? Take on 4 clients in parallel with 3 month contracts and you’ll have 16 done in a year. If you can’t sell it as a custom service it would be a hard sell as a piece of software right?
