Product notes from the engine room

Five decisions, one product.

Five decisions from one employer-owned B2C SaaS for seafarer certification. The numbers come from internal dashboards; where data is missing, I say so.

01

From $100 to $2,171 a month

An audience with no business model, and a closure date already on the calendar.

$100 → $2,171 Total revenue · Oct 2026
02

What 31 premium accounts taught me about what users actually value

My own belief was driving the roadmap. The audit showed users wanted something else.

+79% Organic → premium
03

Pricing experiments: the $1/day failure and the 5 → 3 reset

A cheap plan that looked like growth and cannibalised the subscription.

5 → 3 Plans · $1/day killed
04

An app in three weeks, and the distribution problem behind it

Users wanted a mobile app; the team had no mobile experience and no store access.

3 weeks Research to release
05

A product bet that sold zero

A product I advised against, built anyway, with no demand validation.

0 sales Two months · 10–15 to break even

Context

All five come from the same employer-owned product. I managed it; the company owns it. The revenue is total monthly revenue — subscriptions, PDF archives, lifetime sales and partner placements — not MRR.

Some results are before/after, not controlled tests. I do not claim causality where the data does not support it.
