March 26, 2026 Building 3 digital products in 28 days starting from zero - following along?

I'm a developer with some writing and spreadsheet skills.

Starting today, I'm building 3 digital products with the goal of making as much revenue as possible in 28 days.

Zero audience. Zero existing products. 1-2 hours per day.

The 3 products:

-> Developer Notion OS - a 7-database workspace replacing scattered tools

-> Spreadsheet Pack - 5 Google Sheets for invoicing, project tracking, and budgeting

-> AI Prompt Library - 110 dev-focused prompts for debugging, code review, docs, and more

Why I'm doing this: I want to understand the actual mechanics of selling digital products - what converts, what doesn't, what the platforms are like to work with.

What I'm tracking: Revenue, views-to-conversion rate, which promotion channels actually drive sales.

I'll post weekly updates here with real numbers (even if they're $0).

Anyone done something similar? What worked for you?

I kept rebuilding the same workflows from scratch — prompt templates, tracking spreadsheets, Notion setups. Packaged them into products so other developers don't have to.
