Business strategy & implementation for online educators

Course marketplace instructors have built real audiences — but the platform owns the relationship. Pricing, contact details, and future access all sit with someone else. Most instructors know this is a problem. Few have a clear path out of it.

The answer isn't to move existing courses somewhere new and hope students follow. It's to understand what your audience actually wants next, build a direct relationship with them, design an offer worth paying for, and validate demand before committing to a build.

I work with online educators on the full picture — from diagnosing where you are and what you actually need, to designing the right offer, to building and launching it. Composer Forge was built and funded this way: presold to my own Udemy audience before a single lesson was recorded.

The offer could be a course, a membership, a coaching programme, a community, a tool, or something else entirely. The strategy determines which. The implementation makes it real.

What this looks like in practice:

• Business strategy: clear-eyed diagnosis of where you are, what you have, and what the right next move is — using proven frameworks, not guesswork
• Offer design: building an offer your audience will actually pay for, positioned and priced correctly from the start
• Offer validation: finding out what your audience will pay for before committing to a build — via surveys, interviews, and direct signals
• Independent platform setup: your own platform, your pricing, your student relationships
• Audience migration: moving your marketplace students onto a list you own and control
• Presell campaigns: revenue collected before anything is built — the most efficient way to validate and fund a new product simultaneously
• Launch strategy and execution: end-to-end planning and implementation
• Custom software and app development where needed (React, full-stack JavaScript)
