Currently building:
SubSignal — churn early-warning for small SaaS founders. No dashboard, no AI, no complexity. A weekly email that tells you who went quiet, why, and what to do. sub-signal.com
Growth Radar — Shopify analytics that cuts through the noise: revenue, LTV, returns, customer mix. Built for store owners who want clarity, not another chart.
