A Side-Hustle Phone Lens Brand Sold in Under 2 Months When Its Founder Changed Jobs
THE emo, a smartphone camera lens filter brand launched as a side business by Renpei Taniguchi in 2020, grew by winning fans through crowdfunding and social media. Facing a job-change deadline, he listed it on multiple platforms, met with 4 companies, and transferred it to Mediair Inc. in under 2 months. His own verdict: 'a perfect 100-point sale.'

Why It Sold in 2 Months
There were two reasons to sell. The business had grown to a scale a side hustle could no longer handle, and there was a hard deadline: a job change. Taniguchi was clear-eyed about it: “There wasn’t enough time to make it bigger. Better to have someone with more capability grow the brand I raised.”
What powered the fast close was, in his own words, a simple business model that avoided person-dependency. Product, sourcing, and sales channels were well organized, making the handover easy to explain.
Our Take
A sale with a deadline looks disadvantageous, but it tightens decision-making. The hard stop of a job-start date drove the high-speed process of 4 meetings and a 2-month close. Rather than drifting along waiting for a higher price, setting a deadline — combined with timing strategy like Fin vs Fin’s ‘avoid Q4’ — often produces the better deal in the end.
A D2C brand’s transferability comes down to whether the founder is in the picture. THE emo’s stars were the product and the brand’s worldview; it did not depend on the founder’s personal influencer appeal. Without intending to, he had pre-empted Lively Table’s lesson that person-dependency gets no price.
His own summary — ‘Don’t get overly attached; treat M&A as one of your options, and bigger opportunities open up.’ As an exit for a side business, this case concretely shows the three choices on the table: shut down, leave idle, or transfer.
