This gave me a chuckle. To most people who aren't on HN a software service, no matter the size, is a major business undertaking.
I have a friend who started a pilates studio. She loves pilates and the startup costs are minimal - a few thousand dollars total mostly for a small inventory of yoga pants and athleisure gear to sell. She quit her finance job to get it off the ground thinking it would take at least a year. It took her six weeks to have enough membership subscriptions to make her business profitable. She's a brilliant businesswoman and was working the front desk at a pilates studio and teaching a few classes. After three months she was understandably very bored. Her company still hadn't found a replacement for her so she hired a college kid to sit at the front desk and went right back to work.
There are a lot of "analog" small businesses people could get off the ground in 6 months I just think they aren't the sort we're used to hearing about here because HN is so tech focused.
