What began in 1999 as a small trading company in Seoul now spans trade, energy, mergers & acquisitions and AI development. With partners across nine countries and thirteen cities, we design what comes next for your business. What matters is not what has been done so far, but what can be achieved in the future.
From trade to energy, from mergers & acquisitions and investment to AI development — KCY PARTNERS connects four distinct fields through a single network.
Since 1999 we have run imports into Korea and third-country trade from bases across Asia and Europe, handling household goods and corporate supplies. From sourcing new buyers to advising major Korean corporations, the network built on the ground is our asset.
We work in LNG and crude oil. Carrying over the country-by-country partner network built through trade, we connect supply and demand and examine trading and investment opportunities together. It is also why our North American base sits in Alberta, Canada.
We manage the entire journey in eight stages — market research, target selection, financial analysis, negotiation, due diligence, deal structuring and post-merger integration — working with leading overseas legal and tax specialists.
AI research & development and software supply are registered business purposes, and we build the services ourselves. Most notably, an AI for tax-audit and tax readiness — designed to finish the complex judgement a National Tax Service audit demands in under two minutes.
See what we built →Long before the internet was widespread, our CEO travelled the world in person to build relationships. Those relationships are the network today — a legal partner in Italy, a European partner in Germany, trade partners in Japan, Vietnam and Thailand, and local legal and tax specialists in every region.

Alberta holds the world’s fourth-largest oil reserves, and produces 80% of Canada’s oil and 60% of its natural gas. The Coastal GasLink and Trans Mountain pipelines now carry that output to west-coast ports, opening an export route to Asian markets. Its corporate tax rate is the lowest in Canada, and it has the highest number of engineers per capita in North America. That is why KCY PARTNERS, working in LNG and crude, bases its North American operations in Alberta.
AI that lets a taxpayer check their own exposure to a National Tax Service audit or a fund-source investigation — before the authorities do. Concept, algorithm design and launch were all done in-house. Both services are live; you can try them at the addresses below.
Two diagnostic tracks. For businesses: revenue structure, expense classification and sector risk. For individuals: fund source and gift-tax exposure after a property purchase, calculated the PCI way. Built on the criteria the National Tax Service actually applies, and kept current with each amendment to the tax code.
The first fund-source calculator in Korea to simulate the National Tax Service’s PCI (property–consumption–income) analysis from outside. It compares declared income against actual spending and asset growth to surface the gap that would put a taxpayer on an audit list. Used mainly by cash-heavy businesses and professionals.
There are plenty of tax calculators. A program that computes how the tax authority decides whom to audit is a different problem — because that formula is not published.
The National Tax Service’s PCI logic is not public. We worked backwards from what actually gets flagged in real audits and rebuilt it as rules.
One wrong deduction figure or penalty rate and the whole result is wrong. Every amendment means re-tuning the thresholds.
No name, no phone number. Figures are computed on the user’s own device and never sent to a server. Accuracy and privacy had to hold at the same time.
“You are at risk” is useless on its own. The output has to be something a tax accountant can review and explain to the taxpayer.
Turning an investigator’s instinct into rules. This is not a data problem but an experience problem, and it takes the longest.
In tax, an error is a tax bill. We design conservatively and hand ambiguous cases to a human specialist.
Canada treats AI as national strategy, and one of its three national AI institutes is Amii in Edmonton, Alberta. In December 2024 the Government of Alberta published its AI Data Centre Strategy, setting out to become North America’s location of choice for large-scale AI compute on the strength of cheap natural-gas power, a cold climate and industrial land. Wonder Valley alone is a $70 billion build-out.
KCY PARTNERS works in energy and AI at the same time. Alberta is where those two meet, and that is why our North American base sits there. The capability proven on Korean tax data — designing judgement algorithms against an unpublished rule set — transfers directly to AI for regulated and administrative domains.

In 1999, CEO KangChan Yoon took his first steps into business by establishing a trading company in Seoul. Working from Korea with bases in China, Italy, Spain, Germany and India, he opened new ground in global trade — identifying new buyers through imports into Korea and third-country trade, and securing the company’s growth.
This was before the internet was widespread. He travelled extensively to find partners he could trust, achieving remarkable results through that hands-on approach, and built a reputation for reliability by providing trade consulting to major Korean corporations.
Built on partnerships and friendships formed over many years, KCY PARTNERS today leads innovation in global M&A and investment consulting across Korea, China, the United States, Canada, Italy and Germany. Through collaboration with leading overseas legal and tax specialists, we ensure fast and accurate legal handling and tax resolution.
More recently he has extended that experience into technology and content. He built an AI for tax-audit and tax readiness in-house; he speaks directly about tax-audit practice on his YouTube channel FunFunTax; and he set down the judgement earned in the field in his book “Tax Consulting Methods of the National Tax Service”.
Away from business, he has kept classical concerts going for over a decade — from intimate recitals of a hundred people to full-scale performances of a thousand, funded entirely from his own pocket. All proceeds were donated: medical supplies for children, and the building of sanitation facilities, schools and hospitals in Africa. Hyundai Motor and Korean Air were among the sponsors.
KCY PARTNERS brings together investment know-how and an artistic sensibility through an original, creative perspective — delivering strategic solutions that maximise client asset value on the basis of a deep understanding of global markets.
With specialists formerly of the National Tax Service Investigation Bureau, the channel covers what to prepare, and how, once a tax audit notice arrives.
