Week 1: Understanding US Market
Learn how US founders position their product and communicate with customers and investors.
Many Korean startups struggle in the US not because of the product, but because the positioning, messaging, and communication style are different.

In Week 1, founders learn how to think and communicate like US startups — from product positioning to how to introduce the company to customers and investors.

By the end of the week, founders will have a clear US-facing one-liner and elevator pitch tailored for the US market.
WEEK 1 DELIVERABLES
  • A US-targeted startup one-liner (Korean and English)
  • A refined elevator pitch for customers and VCs
  • Clear product positioning for the US market
  • Your Ideal Customer Profile (ICP) and Winning Scenario

Week 2: GTM Design
Design your first sales motion.
After identifying the right customer segment in Week 1, founders now focus on building a practical go-to-market strategy and starting real outreach.

Instead of waiting for marketing to generate leads, founders learn how to run founder-led sales — identifying their Ideal Customer Profile, crafting the right message, and initiating conversations with potential customers.

By the end of the week, founders will have a clear ICP, a defined winning scenario, and their first outbound sales experiments running.
WEEK 2 DELIVERABLES
  • LinkedIn profile optimized for outbound lead generation
  • At least 20 ICP prospects identified and documented
  • A winning scenario and customer interview script

Week3: Setting KPIs

Founders will also refine their business model and pricing strategy based on how US startups structure monetization.By the end of the week, teams will have a clear AARRR growth funnel and measurable milestones for US expansion.
WEEK 3 DELIVERABLES
  • A KPI dashboard for the startup team
  • A structured AARRR growth funnel

Week4: IR & Storytelling
Turn your startup into a story investors understand.
In the final week, founders translate their product, traction, and market insights into a clear narrative for investors and partners.

Instead of simply presenting data, founders learn how to structure their company story — why this problem matters, why now, and why this team is positioned to win.

Teams refine their pitch, investor deck, and launch messaging, preparing to introduce their startup to investors and the broader startup ecosystem.
WEEK 4 DELIVERABLES
  • A 10-slide US-ready IR deck for investors
  • A refined founder story and pitch narrative
