I kept reading for 3 minutes and still couldn't get a grasp on what kind of "agency" he was talking about. Real estate agency? Literary agency? Travel agency? Can anyone who finished reading tell me?
My guess is he meant software contracting or something related, making software to order rather than making their own products.
And presumably he could've switched to a SaaS business model without leaping into a completely different market. Instead he should have stuck with some B2B area he was already working in and knew well. That was the high-risk part in my opinion.
