불가사리로 40억을 번 서울대생의 아이디어 | 스타스테크 양승찬

Summary

Starstech turns discarded starfish—a costly problem for fisheries and local governments—into an eco-friendly de-icing agent. Its business model combines waste collection, environmental benefits, and a product designed to address corrosion associated with conventional de-icers.

Strategy and operating playbook

• Start with customer and field validation: Before the product was fully developed, the team outsourced early production, distributed samples to local governments nationwide, and gathered feedback through field tests. This helped validate demand and contributed to securing its first investment despite the unfinished technology.
• Use a B2G go-to-market strategy: The company pursued government procurement, reasoning that technical certifications and public-sector references could help it enter the market and later support overseas expansion.
• Make an ambitious market-entry commitment: The interviewee describes building the capacity needed to qualify for procurement, citing a 500-ton requirement, even though the technology was not yet complete. The approach was demanding and risky, but intended to clear a key barrier to market entry.
• Develop the product through R&D: After initial market testing, Starstech focused on improving the product and understanding how it worked, eventually identifying data and technology that became central to its offering.
• Build a mission-led value proposition: Starfish are a nuisance in aquaculture and are often discarded. Collecting and reusing them can reduce environmental harm and lessen the burden of disposal on public budgets.

Company development and outcomes

• Yang Seung-chan developed the business idea while studying and later prepared a business plan during military service. A non-commissioned officer invested ₩30 million, after which the company was established.
• Starstech won first place and the Minister of Environment Award in an environmental startup competition.
• The interviewee says the company reached a notable level in the procurement market within two years, though the specific level is not stated.
• The video subtitles do not provide a clear sales or revenue figure.

Goals

• Short term: Upcycle starfish.
• Mid term: Apply the company’s core technology to other products and expand into additional markets.
• Long term: Grow into a global eco-friendly chemical company.

Actionable takeaways

• Test products with real customers before R&D is fully complete, and use feedback to guide development.
• In regulated or procurement-driven markets, identify qualification requirements early and build a route to meeting them.
• Treat a public-sector reference as a potential foundation for broader market entry, including exports.
• Tie the product’s commercial value to a measurable operational problem—in this case, starfish disposal and de-icer corrosion.
