Stand out from the crowd
Hi, meet your devil’s advocate!
Hi! I’m Sarah, your devil’s advocate!
I’m a founder and product strategist with 15+ years in startups and corporate. One company failed, one’s still climbing — I’ve lived the landmines.
Now I help founders:
Stress-test ideas & pitches
Find product–market fit faster
Build smart go-to-market plans
Get investor-ready (no fluff)
Clarity beats charisma. Passion doesn’t get you funded — numbers do.
If you want honest critique, not sugarcoating, I’m your person. If not, I’m not for you.
Only 3% of startups survive.
Will yours?
Talk soon,
Sarah

My Approach
Dream it
You have a dream, sketch it, let it break free from the dungeon of your mind. Unleash it. It’s ok if it sounds crazy, that’s how dreams are supposed to be. It will find it’s way, “you” will be there to show it the way through.
Build it
Once validated, build it. Only a MVP, nothing more. Again, don’t overthink it. It is supposed to be imperfect and scrappy. You will get all the support you need, there’s no lack of support and connection when you’re with us.
validate it
Get your dream validated until you have a relatively promising level of clarity. It’s your dream, don’t overthink it, own it. The beauty of your story is that it’s going to continue to evolve. Your goal should be to make it feel right for the right audience, right now. Later will take care of itself. It always does.
Remember: There’ always a lot of unknown unknowns!
By the way, this is where you do your first Product-Market Fit analysis!
validate again
Be ready to let the product evolve, let your dream find its shape. Don’t stop it from evolving even if means to pivot and do something different. Validation never stops! This is only the beginning of your journey to satisfaction, success, financial freedom, and being the impact you want to be in the world you belong to, things that touch lives, hearts, and minds, for generations to come! It’s true.
