The era of BYOK is ending.

I asked ChatGPT to reverse-engineer a $99 tool.

Then I built my own version for $2 a month.

A year ago, the smart move was BYOK.

Bring Your Own Key. Plug your API key into someone else's tool. Use their infrastructure, their limits, their roadmap.

That era is ending.

BYOS, Bring Your Own Software, is what comes next. Alex Hormozi coined the term. The premise: coding agents have reached the point where building your own tools is a founder's decision. You scope it, you run the agent, you own what comes out.

I wanted to test whether this was real or just another thing people say on the internet.

I was paying $47/month for Instantly.ai. Good tool. But their sending limits and built-in SOPs kept capping how far I could scale my outreach. I was paying for a ceiling.

So I built Emailify in a week.

Six to eight hours a day, treated it like a real project. This is what I do, so it doubled as a way to sharpen my skills with the new generation of coding agents.

The process:

I asked ChatGPT to fully reverse-engineer Instantly, every feature, every function, the complete picture of what the software does. Then I passed that to Antigravity (by Google), an IDE coding platform, and we built a phase-by-phase plan.

Each phase had a clear scope. Each phase fed the next. By the end, I had fully functional outreach software. Multiple campaigns, hundreds of thousands of prospects, unlimited sends, Gmail API, cloud-hosted on Modal.

Monthly cost: $2 to $4.

A one-week build against $47/month recurring. One month to break even. After that, every month is margin.

Now... the bugs.

There were bugs. Plenty of them. The analytics kept breaking in a particular way that was genuinely painful to debug. It would report that I had sent thousands of emails when the real number was a few hundred. Completely wrong data, which meant I could not trust my own reports until I found and fixed the root cause.

Every SaaS you subscribe to also has bugs. The difference is you cannot see them, cannot touch them, cannot fix them. You file a ticket. You wait. You work around the issue or you upgrade to the tier where it supposedly gets fixed.

With Emailify, I could see exactly what broke and why. Because I designed it around my workflow, the issues made sense. I fixed that analytics bug the same day I found it.

When you build your own software, every problem becomes one you are capable of solving.
