MMEXC, a Mexico-based general contractor founded by Korean entrepreneur Yun Jong-seop in 2007, reported annual sales of $100 million in unspecified boom years. Yun told ChosunBiz he expects about $80 million in sales for 2026 and hopes to help Korean small and midsize businesses connect with suitable local firms as they enter Mexico. Those figures and plans are interview-reported, not independently verified financial results or evidence of an operating referral service.
How Yun moved from gloves to construction
Yun told ChosunBiz that he first visited Mexico in 1993 and settled there in 1997. He opened a factory producing cotton work gloves, later supplying gloves to construction sites. That customer base brought him closer to the construction sector.
From site coordination to contracting
The interview says Yun coordinated work at a wind-power-related site in Monclova in 2005. He then began supplying construction materials, including rebar and concrete, before founding MMEXC in 2007. The sequence shows a gradual move from manufacturing and supply into project work and general contracting, rather than a direct leap from the glove factory to a large contractor.
What MMEXC does and how it grew
ChosunBiz describes MMEXC as a general contractor. According to Yun’s account in the interview, early opportunities included machine foundations for suppliers following LG Electronics’ entry into Mexico, followed by a project connected with Kia’s entry. Yun called the Kia-related job the company’s largest project up to that point. The profile does not provide a project list or independently verify the company’s work history.

Yun said the team comprised 10 Korean employees and about 40 local architects. Those are interview figures, not a separately verified employee count. He also said annual sales reached $100 million during boom years, without identifying which years. For 2026, he expected annual sales of about $80 million; that is a forecast, not confirmed year-end revenue. The profile does not cite audited accounts or company filings for either figure.
Yun’s stated plan to help Korean SMEs
Yun told ChosunBiz that he wants to help Korean small and midsize enterprises seeking to enter Mexico find and connect with suitable local companies. In the Korean-language interview, he described wanting to serve as an export gateway for that purpose. The account presents this as a goal, not a service that businesses can currently apply for.

The interview gives no eligibility rules, contact channel, program details or confirmation that MMEXC or World-OKTA runs a formal referral program. Businesses considering a Mexico entry would need to verify directly whether any such support is available and what it covers.
His World-OKTA roles, as reported
The profile places Yun’s World-OKTA activity in the organization’s Monterrey chapter. It says he was a founding member in 2016, became chapter head in 2021 and was serving as Central America regional head in 2026. These dates and roles are reported by ChosunBiz; the profile does not describe a specific SME placement service associated with them.
What the interview establishes—and what it does not
- Company background: The profile traces MMEXC’s path from glove manufacturing and construction-site supply through materials and coordination work to general contracting.
- Reported scale: The $100 million sales figure refers to unspecified boom years; the roughly $80 million figure is Yun’s expectation for 2026. Neither is presented as audited financial data.
- Opportunity history: The account links early work to suppliers following LG Electronics’ Mexico expansion and a later Kia-related project, based on Yun’s interview.
- SME support: Yun expressed an intention to connect Korean firms with local companies, but the profile does not establish an active program or how to access one.
