You already know how to build.

This is the half nobody taught you. Under $10k a month, the thing that actually decides whether your business survives isn't your code. It's whether you can get in front of a stranger and ask for money before you've built anything impressive. Sell First is the exact framework I've used to sell every digital and software product I've ever sold, sometimes before a single line of it existed.

Don't waste months building something nobody wants.

The most expensive mistake a developer can make is spending months on a product, launching it, and hearing nothing. Sell First shows you how to find out whether people will pay before you build, so you stop guessing and stop burning time on things nobody wants.

Building for months before talking to a single customer
Launching to silence
Solving a problem nobody will pay to fix

What people are saying

Message from Marin: Your framework really helped me. I contacted around 100 people, found nobody was willing to pay, and stopped development. Thanks to this framework I had more information in 7 days than in 7 months about the market. Next product, always: Sell first

Eric shares his first trial, then writes: you've certainly played an important role in me getting this far, and that forced me to take that step, I would have drug it out forever

Who's teaching this

KS

Khalil Stemmler

I'm a software developer, product builder, and writer. I created The Software Essentialist, where I teach the software engineering fundamentals most developers are missing. I've been selling digital and software products since 2015, building and running the funnels behind them myself, which means I've hit every roadblock in this book firsthand, technical, psychological, and metaphysical. Right now I'm building The Abstractionist, where I teach business, identity shifting & human architectural recalibration systems for developers & technical creatives.
