Conventional startup wisdom says: focus. Pick one idea. Go all-in. I do the opposite. I build multiple small products, each solving a different problem, targeting a different niche, testing a different hypothesis.
Portfolio theory from investing applies to indie building: spread risk across multiple bets. Some will fail. Some will stagnate. One or two might succeed. My current portfolio: Genes, Playtoob, On Tap, Malt FM, PDMerch, ListPickers, Expo.Live, Rockers.im, FeedAlgo.
Each product is an experiment. Each answer teaches me something. Even failures provide data. When you build multiple things, detachment becomes easier. This psychological buffer prevents burnout and keeps me shipping.
