A 48-year-old took over a hypochlorous-water dealership from an 84-year-old founder. Under a year into the job, sales were up ~150% year over year

There are two ways to read a story where performance jumps right after someone buys a company through M&A. Was the buyer excellent, or did the seller regain their drive? What makes this case interesting is that the buyer himself explicitly says it’s the latter. “This is less my own achievement and more a kind of ‘lucky punch’ from the previous owner.” The transfer amount is undisclosed, but in its place, what happened in the year after succession is described in concrete detail.

Timeline

The previous owner was 84 at this point, having spent about 4 years searching for a successor. Matsuki reflects, “He’d also been looking for a successor for about 4 years and it was around the time he wanted to settle it, so maybe that timing worked in our favor too.”

He bought “the structure of the business,” not “the product”

Matsuki is candid: “I didn’t have strong passion or affection for ‘hypochlorous acid water’ from the start.” The axes he used to select the deal were just two: not holding much inventory, and not being tied to a location.

Oak Sales makes hypochlorous acid water (used for disinfecting and deodorizing air and equipment), procures generating machines from a manufacturer to sell, and also handles maintenance for buyers. Customers range from cosmetics manufacturers’ factories to ordinary households, centered on B2B. The structure Matsuki saw in this deal was clear: no need to hold inventory, since orders can be placed with the supplier after a sale is booked. Maintenance and running consumable-liquid sales continue after the initial sale. A stable B2B customer base exists, with room for cross-selling.

“It’d be nice to have affection for the product itself too, but I don’t think it’s essential,” he says. What he valued instead was the “tangible feel” of the product actually being used in factories and medical facilities.

The turning point wasn’t the acquisition itself — it was the relationship design afterward

Typically, in business succession, once the handover period ends, the relationship with the previous owner ends too. Matsuki did the opposite. “For us it’s totally the reverse. We’re still working together like crazy.” The previous owner operates with the freedom of something like an honorary advisor, continuing to go out and do sales work.

His explanation: “At the moment of business succession, the previous owner is often carrying a sense of isolation, or the company’s own motivation has faded and the pace has slowed down. Then someone like me, a ‘young upstart’ from his perspective, comes in, and a new team forms. And the old man gets fired up: ‘Alright, let’s do this again!’ I work hard to make it easy for him to keep working, and he keeps going out and doing sales like crazy.”

Sorting out the before and after: before succession, an 84-year-old manager had been running the company alone while searching for a successor for 4 years. After succession, sales became the previous owner’s role and organizational structure-building became Matsuki’s, in a division of labor. The roughly 150% year-over-year sales growth is explained as a result of this division of labor.

What’s at work here is something that never shows up in an acquisition’s asset valuation. What appears on financial statements is inventory, receivables, and equipment, not the fact that “the owner’s work rate had dropped due to isolation.” What the buyer brought wasn’t sales ability per se, but an environment where the will to do sales came back.

Twelve meetings in six months — a contact volume easy to overlook

There’s another element that’s unglamorous but replicable. Over the negotiation period from October 2023 to April 2024, they held meetings roughly every 2 weeks, a dozen-plus by simple count. The previous owner, despite being 84, replied quickly and traveled to Shibuya for discussions.

In small-scale M&A, since the budget available for due diligence is limited, judging the other party relies more heavily on the frequency and quality of contact. A dozen-plus in-person meetings over six months reads as an investment to gather information that documents alone can’t capture. In fact, Matsuki says that by the negotiation stage he already felt the previous owner as “a father-like figure,” and the foundation for the post-acquisition co-management design was laid during negotiation itself.

Not entirely smooth sailing

Clashes in values happen regularly. “We fight all the time, honestly. There are arguments over ‘he said, I said’ or differences in how to approach the work.” Matsuki acknowledges that he sometimes finds the previous owner’s sense that “cash matters above all” or his willingness to push through gritty sales work in any situation “a bit old-fashioned,” but also says, “I respect him far more as a manager than some slick, salaryman-style president trying to move people with polished words, when he grinds it out and hustles to make sales.”

The more essential risk is that the main driver of the 150% growth is an 84-year-old individual. Matsuki recognizes this fragility himself, saying, “Right now, as long as he’s healthy, we want him working as much as possible, letting him move freely in something like an honorary advisor role, while we’re in the middle of building the organizational structure so we can run the company as a team.” Having bought a company partly to escape dependence on any single person, they now find another form of that same dependence supporting current performance, and whether this transition completes is not yet something that can be observed.

With the transfer amount undisclosed, whether this deal was a good one from an investment-return standpoint can’t be judged from outside either. The only reference point available is the growth rate.

What can and can’t be replicated

What’s replicable is how the selection criteria were set. Rather than emotional attachment to the product, he filtered deals on structural items, inventory levels, location dependence, existence of recurring revenue, and room for cross-selling. And he secured enough contact volume during negotiation. Further, he designed the relationship on the premise of keeping the previous owner engaged after the handover, rather than cutting ties. None of this depends on the amount of capital available.

What’s hard to replicate is the luck of landing on a compatible seller. A seller who had spent 4 years searching for a successor and was “ready to settle it,” who at 84 was active enough to travel to Shibuya, and who wanted to keep doing sales even after succession, a seller with all three of these is uncommon. Matsuki’s 20-plus years of project management experience and his MBA aren’t things you can simply prepare either, though he himself modestly rates their contribution: “The MBA taught me the basics of finance and accounting, but actually buying and running a company has been a completely different level of growth.”

His advice is “just take the leap”, grounded in the reasoning that “a company is a legal entity, so it’s ‘limited liability.’ Even if you fail, you only have to take responsibility within the scope of the paid-in capital.” It’s worth a mention, though, that this logic only holds if you aren’t carrying a personal guarantee.
