Bootstrapping a side project into a profitable seven-figure business

Great job on this webapp, it's a really easy-to-use platform. I've toyed with the same startup idea myself, having tracked my personal finances and life projection for years now using Google Sheets, Grafana and other tools.

Just an annecdotal bit of feedback: I would like to continue using ProjectionLab but $109/year is beyond what I'm willing to spend, especially given ProjectionLab doesn't integrate with any live tracking of property prices / investment portfolio valuation etc.

If it were $40/year I probably would subscribe. But $109 is too much to justify (and I am reasonably well off).

Have you A/B tested different pricing levels to find the sweet spot that maximises revenue?

I tend to agree with the sentiment. The only reason I subscribed to ProjectionLab was to appreciate the hard work of Kyle. Otherwise, "New Retirement" (now called Boldin) serves my purpose. It provides similar features and it provides automatic updates too.
