Position Size Calculator is a focused tool for trade sizing and risk-reward math, and it’s already revenue-stage which matters: it generated $248 in the last 30 days while carrying an MRR of $35. The business shows strong short-term momentum (up +134%) and an unusually healthy profit profile (margin 85%), which suggests low operating overhead or a largely digital delivery model.
Those positive signals sit next to clear limits: absolute recurring revenue is very small, so growth is easy to move percentage-wise but hard to rely on for scale. The product being listed for sale is an explicit signal about the founder’s intentions and could be an acquisition opportunity or a red flag depending on buyer diligence. For founders, the numbers point to product-market fit at a small scale and clear optionality; for potential buyers, they point to a low-cost, high-margin asset that needs a plan to convert one-off demand into stable recurring customers.
