Ask HN: Is there a marketplace for small working businesses?

I just realized I'm good ad getting ideas and bringing them to profitable but horrible at scaling them. For instance: - I started an online apartment reservation website in 2001 only to keep it small and to be destroyed when Airbnb came along. - I tried to build a co-living before there were enough digital nomads. - I was a travel coach before the word even existed (I taught people to travel independently in Bali).

But I never made these things big.

I'm Italian and we have this "keep it small and pass it to your son" attitude. Think espresso bar and Starbucks, or pizza and Pizza Hut. Honestly, I don't think I can, or should change, this attitude. That's what I do best.

So the question is: How to sell a small but profitable running business with a lot of growth potential to someone who has the drive and capabilities to make it big?

I couldn't find a marketplace, so maybe here's another idea for a startup.
