Donald Leo's strongest launch pulled 50 interest. Their weakest tracked launch pulled 13. A 3.8x spread between best and worst is typical for a serial launcher. Consistency matters more than one big hit.
We track the makers listed on each product's launch page. A founder appears here if they're credited on 3 or more products in our index.
Serial builders. Some founders launch multiple products across different categories. Others iterate publicly, launching new versions or pivots as separate products. Both patterns show up in the data.
It means the community paid attention. High total interest across many launches signals consistent relevance. But a founder with 3 launches averaging 0.40 engagement may have built better products than one with 20 launches averaging 0.08.
Sum of each product's engagement ratio divided by number of products. It weights every launch equally regardless of interest score. A founder with consistently high engagement across small launches will rank higher than one with one viral hit and many duds.
