Buyer conversations
What you're listening for: real buying signals, not polite interest.
Encouragement isn't evidence.
Ask people whether your idea sounds good and they'll tell you it does. They're being kind. That's encouragement, not proof, and it's the most expensive feedback you'll ever act on.
The only signal that counts is someone willing to pay.
Without it, you can burn months of work, a big chunk of your savings, and the reputation you spent a decade earning. All on something the market was never going to want.
Invest in the right idea, the right way.
We don't ask people whether they like your idea. We help you sell it, and read whether real buyers actually pay.
Reduce Risk
Know what the market will pay for before you risk your savings on a guess.
Find Your Real Buyers
The people who'll pay are often not who you expected. We find out who they really are.
Honest Feedback
You'll hear what buyers actually think, not what they think you want to hear.
Fast Turnaround
Four weeks from first conversation to a decision you can act on. Not four months.
A Clear Decision
Messy conversations turned into one straight answer on what the market will actually pay for.
A Clear Next Step
You leave knowing what to do on Monday morning, not holding a report that gathers dust.
Four weeks. A win every week.
No long discovery phase, no workshops that end in sticky notes. Every week moves you closer to a buyer.
Week 1
Problem Architecture
We pin down the real problem, define your ideal customer, map who else solves it, and find where you actually stand out.
Weeks 2–3
Real customer conversations
You run them. We design the questions and read the signals with you. Wherever your network allows, these come from people you already know, so we keep cold outreach to a minimum.
Week 4
The decision
An objective review of what you heard, a clear answer on what the market will pay for, and the map to take it there.
Everything you get in four weeks
Five components. Each one exists to move you closer to a paying buyer.
The Commercial Reality Engine
Four weeks of hands-on 1:1 coaching. We do the work together, not a course you watch on your own.
The Ideal Customer Profile
Who your ideal customer really is, the exact problem you solve for them, how to reach them, and how to win them over against the alternatives.
The Warm Conversation System
A sourcing system, outreach scripts, an interview framework, and a buying-signal cheat sheet, so you know a real "yes" when you hear one.
The Clear Decision Framework
Turns messy, contradictory conversations into a clear call: commit, refine, or pivot.
The Launch Map
A launch plan, a go-to-market map, and a first-customer playbook. You leave knowing exactly how to take it to market.
The guarantee
The No Dead Ends Guarantee
Show up and complete your 10 buyer conversations, and you'll walk away with one of two things: validated demand and your first real customers, or a clear, evidence-based direction on exactly what to change.Do the work and don't leave with one of those two, and I keep working with you free until you do.
You will never leave with a dead end.

In today's hyper-competitive landscape, his approach is invaluable for truly understanding target audiences. I only wish we had incorporated Tomislav's expertise into our projects sooner."

Questions people actually ask
What if my idea is wrong?
Then you find out in 4 weeks instead of 18 months, for a fraction of what a full launch would have cost. And you don't leave empty-handed. You leave knowing which part was wrong and where the evidence points instead. Being wrong early is a result, not a failure.
Do you find the people I interview?
No, and that's deliberate. You learn to source conversations from your own network first, because those are the people who'll actually take the call and tell you the truth. We keep cold outreach to a minimum, and the sourcing skill stays with you after the Sprint ends.
How is this different from an accelerator or a design sprint?
An accelerator optimizes a business you have already committed to. A design sprint produces a prototype. Neither tells you whether anyone will pay. This is 1:1, centered on real buyer conversations rather than workshops, and the deliverable is commercial evidence, not a prototype, a pitch deck, or a demo day.
What do I walk away with?
A clear decision backed by real buyer conversations, a launch plan, a go-to-market map, and a first-customer playbook. At best, customers already waiting. At worst, clear evidence on what to change. Never a dead end.
Who is this NOT for?
People who want their idea validated rather than tested. If you're looking for someone to tell you you're right, this will be uncomfortable and you'll waste your money. It's also not for pre-expertise first-timers. This works because you already have deep domain knowledge and a network worth talking to.
