What you actually walk away with
Most people who join 12BRAVE have been thinking about starting something for 1–3 years. By the end of the program, they've stopped thinking and started. Here's specifically what that looks like.
Clarity on which idea to actually pursue, even if you arrive with five
A tested offer, validated with real people, not just in your head
Your first paying clients, and the plan how to scale from there
A weekly action rhythm that fits around a full-time job. AI shortcuts where possible
A real thing in the world, not a website noone sees and not a business plan
A community of peers doing the same thing who will share their learnings alnóng the way

Why we built this?

We spent 12 to 20 years in corporate and consulting. We were good at it. We genuinely liked a lot of it. But at some point the question changed. It stopped being "how do I get to the next level" and became "is the next level actually what I want?"

For us the answer was no. Not because something went wrong. Because something else started pulling harder. We did not want to wait until 55 to find out what we were capable of building on our own. So we started, carefully, while the salary was still coming in. 12BRAVE is what we wished had existed when we made that shift.

We started small — and it gave us options

While still in our full-time roles, we had already started experimenting on the side with:
Consulting
Mentoring
Launching small AI products
These projects gave us flexibility and experience. So when we left corporate, we weren’t starting from scratch.

That experience led us to build the kind of program we wish we had five years ago — a clear, structured path to launching your own thing, with hands-on support, expert guidance, and real accountability. That’s how 12BRAVE story began.

FAQ

What will I actually get?

By the end of the program you will have tested a real idea with real people, had your first conversations with potential clients, and know exactly what you are building and for whom. Most participants get their first paying client during the program. All of them leave knowing their concrete marketing plan, tested

Will I have time to participate while keeping my main job?

Yes, the program is specifically designed for full-time working professionals. You would need 4 to 6 hours a week to work on your business idea with us.  If you have spent the last two years reading about starting a business without actually starting, you are already spending this time. You are just not getting results from it yet.

Is this a “quit your job” program?

No. You keep your job the entire time. The program is built specifically for people who are not ready to quit and should not have to. You build something real alongside the salary. If at some point you want to make a bigger change, you do it from a position of strength, not a leap of faith.

What if I don't have a clear idea yet?

Most people who join do not. Some have one idea they have been sitting on for two years. Some arrive with four ideas and no idea which to pursue. Both are completely normal and exactly what the first weeks of the program are designed to resolve. Clarity is something you build inside 12BRAVE, not something you need to arrive with.

Is there a result gaurantee?

If you show up and do the work, you will make progress. That is not a marketing line, it is what the structure is built for. If you ever feel stuck, we offer additional 1-1 coaching at no extra cost until you get your first clients. We only accept people we genuinely believe we can help. That is what the 30-minute call is for.

I have been thinking about starting something for years and never followed through. What makes this different?

The structure. Every week has one specific thing to do, a deadline, and a group of people who will notice if you do not do it. The reason most people stay stuck is not lack of ideas or talent. It is lack of a forcing function. That is what 12BRAVE is built to be.
