Sarah Michelle NP Reviews: A $7,000 Dental Bill Sparked Exam-Prep Classes That Sold for Eight Figures Two Years Later

(Yen conversions in this article use an approximate rate of ¥150/$1.)

She clenched her jaw so hard from exam anxiety that she cracked a tooth, and started a side hustle to cover the $7,000 (about ¥1.05M) implant bill that followed. Two years later, that side hustle sold for eight figures (in the tens of billions of yen range) — an almost too-perfect arc, but it’s the true story of Sarah Michelle NP Reviews. What makes this case valuable isn’t just the size of the outcome. It’s that the inside of the sale process (rejecting the first offer, a falling-out with a broker, negotiating directly) is documented in specific detail. It’s a rare primary source on what actually happens when an individual sits across the table from a large buyer.

The business’s trajectory

The starting point: not “the teacher,” but “the friend who passed with you”

Boes had tutoring experience and had taught nursing students at the college level, so teaching itself was an extension of her day job. But the actual starting point was purely the dental bill, no business plan, no funding raised. She began with a free Zoom class for 30 classmates, and offered the first 100 people access for free through Facebook Messenger. Even after going paid, the price was a flat $25, paid via Venmo and Cash App, a setup you’d hesitate to even call a business.

And yet it hit $100,000 in 3 months and $1,000,000 in 7. Ad spend was zero. All of that growth came from word of mouth inside a Facebook group.

• Q&A, not lectures: Rather than “a teacher’s lecture,” the format of “studying together with a friend” resonated with exam-anxious nurses. The fact that Boes herself had passed the same exam just months earlier built a kind of trust that authority-brand prep companies couldn’t offer
• Pass reports became the advertising: A culture emerged, unprompted, of students posting screenshots of their pass notifications in the Facebook group. A 99% pass rate track record spread on its own as a result
• Students eventually topped 40,000. The main offering became a $260/month subscription bundling every course plus a last-mile study guide, run by a team of 4 full-time staff plus contractors

The $100,000 the app burned — a record of growing pains

The failures are recorded just as plainly. As students surged, the third-party software platform she was using kept crashing. That led to a decision to build a proprietary app, investing $100,000 (about ¥15M), but the project stalled out before it was finished. It’s a textbook case of infrastructure investment decisions in an individual business failing to keep pace with a 7-months-to-$1M growth rate. What stands out is the decision afterward: rather than digging in to rebuild the infrastructure, she kept running on the existing setup all the way through the sale.

The negotiation: a “magic number” fixed before she ever sat down

The sale process is first-rate material on negotiation. Here’s the timeline.

First, preparation. Boes and her husband built a financial model, ran best- and worst-case scenarios, and, before ever meeting a buyer, fixed a magic number, what she calls her “north star”, the number at which she’d actually sell. In parallel, she studied the mechanics of a sale through the book Built to Sell and the podcast My First Million, and consulted a friend who had exited a unicorn company as a female founder, as well as an M&A lawyer. She came to the table only after arming herself through self-study and her network.

The offers that came in were, in her words, “wildly all over the place.” Blueprint Prep’s initial offer came in below her magic number, so she rejected it. At that point, the broker, who was also serving as her growth strategy advisor, snapped that she was “ruining this relationship forever.” Boes concluded the broker’s emotional attachment to closing the deal was clouding his judgment and fired him. A few months later, Blueprint came back with a re-offer within her magic-number range, in eight figures, and she negotiated it directly herself, with no broker.

“Interviewing” the buyer

The buyer’s side is documented too. Blueprint operates under PE firm New Harbor Capital, and this was its fifth acquisition under that ownership (the fourth in the preceding 18 months). It had already acquired Rosh Review, a medical exam-prep company, but had nothing in the nursing space, Sarah Michelle NP Reviews filled that gap. On Boes’s side, the reasons she cites for choosing this buyer were a learner-first set of values, a leadership team that’s half women, and the fact that its LSAT division was led by its own founder-CEO (evidence of a culture that keeps founders on after an acquisition). It’s a structure where the seller is interviewing the buyer, something only possible because she had multiple offers on the table.

The deal structure itself is instructive for anyone selling a personal-name business. She kept the trademark on her own full name for herself, and transferred only the trademark on the business name to Blueprint. She negotiated a carve-out on how her name and likeness would be used. The business is set to migrate to the Blueprint brand over the long term, a design that preserves the reputational value of a founder-tied brand while separating it out in stages. Under her earnout terms, she stayed on as Chief Nursing Officer through December 2024.

After: where the sale proceeds went

In the middle of the sale process, Boes learned that the daughter she was expecting had a life-threatening congenital heart condition. Her daughter underwent six surgeries by five months old. Since then, Boes has pledged a $15M (about ¥2.25B) donation to the Norton Children’s Heart Institute in Louisville, Kentucky. Her attention after the exit has turned not to a next venture but to philanthropy. The follow-up shows that “selling for freedom” wasn’t an exaggeration.

What this case teaches

“Personal, first-hand credibility × a community sharing pass results” is one of the strongest growth loops in education businesses. It’s the same structure as FeedbackPanda’s teacher community: in fields where success is visible (passing an exam), customers’ own success posts become the best advertising. Zero ad spend and $1M in 7 months is the output of that loop.

Setting your walk-away price “before an offer ever arrives” is the essence of negotiation. If you think about it only after seeing the other side’s number, you get pulled by anchoring. And as this case shows, a broker’s own interest (closing the deal) doesn’t necessarily align with the seller’s. Alongside PsychCentral’s price-driving and EventMB’s two failed deals, the seller’s real weapon is always “the standard by which you’re willing to walk away.”

Selling a personal-brand business (one carrying your own name) can be resolved by splitting the trademark. Keeping the name-based trademark for herself while rebranding the business in stages is a different solution, a “separate it out afterward” pattern, from Fully Booked VA’s pre-emptive rename.

Conditions for replication

Three lessons outlast the specifics of this deal. In fields with a clear pass/fail credential or exam, being a recent passer yourself is, in itself, a form of differentiation. In fields where success can be proven with a single image (a pass notification), a community becomes a self-propelling advertising engine. And the discipline of setting your threshold in advance, and reading a broker’s incentives clearly, is a negotiation craft that applies regardless of business size.

On the other hand, an eight-figure exit rests on the scale of the US NP credentialing market and the depth of PE capital rolling up education businesses. There isn’t necessarily a buyer waiting at the same multiple in Japan’s certification-exam-prep market. And the self-propelling spread of a track record like “99% pass rate” doesn’t kick in until student numbers cross a certain scale. What’s importable here is the design of the growth loop and the craft of negotiation, not the going rate for the exit itself.
