Before You Hire That “Startup Whisperer,” Read This

They were just plain lucky: A friendly reminder to look beyond the résumé headline.

Across every startup there’s a quiet, daily hunt for inspiration.

1. The CEO looks for the next strategic leap.
2. The head of marketing wants a new growth channel.
3. The engineers day-dream about the stack that will scale to a million users.

So we read case studies, listen to podcasts, and—when budget allows—hire consultants or advisors who have “already done it.”

Most of those people are generous, talented, and genuinely helpful. A few, however, belong to a special species I call the “one-time wonder.”

1. Who is a “one-time wonder”? Think of the early employee who rode a rocket-ship startup from Series A to IPO and now bills themselves as an oracle. Their LinkedIn headline glows—Founding Engineer at X, Early Growth Marketer at Y. They absolutely did great work. But their playbook is built on exactly one context, one product, one moment in time. Success can be sticky; it’s easy to believe what worked once will work everywhere.
2. Why that can be risky for you
   1. Limited lens. Five years inside a breakout company can feel like 20, yet it’s still one company, one market, one business model.
   2. Right place, right time. The win may have depended more on market timing, a standout CEO, or a once-in-a-decade product-market fit than on any single individual’s tactics.
   3. Textbook advice. To fill the gaps, some one-time wonders default to what they’ve read or heard elsewhere—ideas that sound polished but aren’t grounded in data from your situation.
   4. Overconfidence bias. Success is thrilling. Occasionally it tilts into “I’ve cracked the code” territory, even when the code was largely context-specific luck.
3. Important disclaimer Being an early employee at an iconic company is an accomplishment, full stop. Many such people are thoughtful, humble, and bring enormous value. The point is not to dismiss them—it’s to evaluate any advisor with the same rigor you use when you hire a full-time teammate.
4. A quick checklist before you sign the contract
5. Range of experience
   1. Have they shipped or sold more than one kind of product?
   2. Have they operated at different stages: pre-seed, Series B, post-IPO?
6. Business models and markets
   1. B2B, B2C, enterprise, freemium—can they speak to more than one?
7. Constraints similar to yours
   1. Team size, burn rate, geography, regulatory hurdles. Advice that needs a 30-person data team is useless if you have two interns.
8. Evidence over anecdotes
   1. When you ask, “How would you approach our churn problem?” listen for data, experiments, and hypotheses—not just “This is what we did at Slack/Uber/Stripe.”
9. Humility and curiosity
   1. Do they ask you questions? Challenge their own assumptions? Adjust when new information appears? Those are green flags.
10. Turning the lens inward Even the most battle-tested advisor can’t substitute for your own learning loops. Invest in your own instrumentation, run small experiments, hold regular retros. Outside insight is a supplement, not a substitute, for doing the work.
11. The gentle takeaway Seek inspiration everywhere—books, podcasts, mentors, even the occasional one-time wonder. Just match the advice to your reality, and remember that lightning rarely strikes the same way twice.

If a potential consultant clears the checklist above, fantastic. If not, keep looking. Your startup’s runway, morale, and velocity are too precious to gamble on someone else’s lucky break.
