Turn 10+ Years of Corporate Experience Into Your Own Side Business
You have built more expertise than many startup founders will ever have. You just have never been shown how to package it, price it, and find the people who will actually pay for it. Be it a consulting offer or a Product.
We built 12BRAVE for mid-to-senior professionals with 10 to 20 years in corporate — engineers, finance, and product people. People who have been thinking about starting something on the side for too long without actually starting.
AI has removed most of the reasons to wait. You do not need months of work before you can launch your first test, now it takes just a couple of weeks. And we will be there with you along the way
What you'll walk away with:
↳ A packaged offer ready to sell, with clear positioning and pricing
↳ Your first paying clients and a concrete plan to get more
↳ AI shortcuts for customer research, competitor analysis, and go-to-market
↳ A weekly rhythm that fits around a full-time job and does not require you to quit anything
BONUS: 8 successful founders joining live to share what actually worked

Do what your corporate career never taught you — validate a real idea, package your expertise, and get your first paying clients
Define which idea to actually pursue, even if you arrive with five
Match your idea to your personal strengths and real market opportunities. Your side business should bring you joy, not just extra work
Walk away with 1–3 concrete hypotheses to test — learn how to prioritize them
Run customer research and get real proof, not AI hallucinations
Build a competitor analysis that tells you exactly where the gap is
Create an AI synthetic user based on your target customer to pressure-test your assumptions
Turn your expertise into a clear, positioned offering with a real price
Build a landing page for your offer — vibe-coded, live, and ready to share
Build your go-to-market plan and know exactly what to do the week after the program ends
Learn how to combine multiple AI tools to run research, validate ideas, and reach customers
Understand where AI accelerates your work and where your critical thinking is irreplaceable
We cover a range of tools across the program — the goal is to make you tool-agnostic, not tool-dependent
Position yourself as a credible voice in your niche so your first clients come from recognition, not cold outreach
Build a distribution network that brings opportunities to you rather than you chasing them
Turn your corporate credibility into founder authority

Who this course is for
10–20 years in corporate. You have the idea. You just need the structure, the deadline, and the right people to finally make it real.
Too many ideas, no clear direction. You don't need more thinking time. You need a structured way to pick one and test it fast.
Your job is fine — for now. You want a real Plan B built on your expertise before you actually need one. Without quitting anything.
Prerequisites
10+ years in a corporate or consulting role
Engineering, finance, product, strategy, or operations. You have seen how businesses actually work from the inside.
Zero business experience required
But you need to be ready to go out there. Talk to potential customers, test your idea. The framework is ours. The action is yours
A basic curiosity about AI
You do not need to be technical. You need to be willing to experiment with tools you have not used before.

SPICED - Head of Brand & CommunityI was lucky to get into this program. It gave me a steady and clear plan for how to launch my product. What is even more important, it gave me the support of the group and a sense of belonging, of doing something together. It's not only knowledge, but also great networking
