Trusted advisors to early-stage technology-based founders
Know in 90 days whether your product has a real market.
You have a great product. But if you can't explain who it's for and why they need it, nothing else works. That's what we fix, together.
Most founders build before they listen.
You've shipped. You've pitched. You've iterated. But traction is inconsistent, customers say they love it but don't come back, and your team can't agree on who you're actually building for.
This isn't a product problem. It's a customer clarity problem. And it's costing you runway, energy, and conviction.
The founders who find product-market fit aren't luckier, they're more rigorous about who they're talking to and what those conversations actually tell them.

The PMF Sprint — 90 days to clarity.
The Product-Market-Fit (PMF) sprint. Three phases. Twelve weeks. A clear answer at the end.
Phase 01 · Weeks 1–2
Assumptions Audit
We surface every assumption baked into your product, your pitch, and your roadmap. You'll see clearly what you know versus what you've been hoping is true.
Phase 02 · Weeks 3–8
Discovery Sprints
You do the interviews. We design them — the right questions, the right personas, the right structure. I coach you through every round so the signal is real, not confirmation bias.
Phase 03 · Weeks 9–12
Synthesis & Direction
We turn the evidence into clarity: who your real customer is, what problem you're actually solving, and whether the signal says scale or pivot.
Right fit. Wrong fit.
For you if
- Post-MVP founders who have a working product but inconsistent traction
- Founders who feel stuck on who their real customer is
- Teams with 6–18 months runway who can't afford to guess
- Mission-driven founders building something that matters beyond the return
Not for you if
- Pre-idea founders who haven't built anything yet
- Founders with strong recurring revenue who already know their market
- Founders who want someone to do the interviews for them — you do the talking, we guide the listening
- Founders seeking a co-founder or operator — this is focused advisory, not fractional execution

Question 2

Question 4
We have 18 months or less of runway.

About
Enrique Shadah
Founder, Expert Collective
I am an operator, not a theorist. As an adjunct instructor at MIT with deep experience guiding early-stage companies from fuzzy idea to funded reality, I thrive in guiding hard-tech founders through the tough path of early stage company building.
I am not an expert in your industry, but on the process of finding a market for your technology. That distinction matters. You know your space. I know how to help you listen to it.
I've helped founders raise capital, discover customers they didn't know existed, and walk away from ideas that would have consumed years. Honesty is one of my core values.
- $35M+ in capital raised by my clients
- 50+ early-stage companies guided
- MIT adjunct instructor & mentor
- MIT Excellence Award (2016) and MIT Infinite Mile Award (2026)

How to know if your startup is on track?
Founders grapple with anxiety over whether their decisions will lead to growth and stability in their companies. Time constraints and limited resources force critical choices without adequate information. Business patterns solve this.

Can you or should you escape the profit motive?
The modern concept of business prioritizes profit over social responsibility, a shift from historical industrious values. Milton Friedman's profit-centric doctrine contrasts with Adam Smith's consumer-focused view. Successful companies should adopt a mission-driven approach, ens…

Three foundational business equations everyone thinks they know well
Many people I have encountered throughout my professional and personal life believe in having a job, making money by hustling a side gig or creating a new business. Very few question the economic principles underlying their respective businesses and why they are sound. This is n…
