“I can’t find people to build with, and I don’t know where to start.”

Aspiring founders · early-stage teams

An early team rarely stalls for a single reason. It cannot tell whether it is stuck because it lacks people, or whether it cannot hire because the work has never been sorted out.

Mentoring is not a place to hand out answers; it is a place to set the order. We pick the one thing to work on now, and leave behind what to verify by the next session.

Problem definition, 1 page

We define on a single page whether what is blocking you right now is people, product or money

Execution priorities

We write down what to do over the next 6 months — and what not to do

Connections

When useful, I introduce support programs, mentors and practitioners

Fit

When it fits, and when it does not

This is when to reach out

  • You are deciding alone, with no one to ask whether the decision is right
  • You have the item but have not found anyone to build it with
  • When you have been selected for a support program and cannot work out what comes first

In these cases I recommend a different approach

  • 당장 이번 주 마감인 서류를 대신 써 줄 사람을 찾는 경우, 그건 다른 방식이 맞습니다
  • 이미 방향이 확고하고 검증만 원하는 경우, 한 번의 자문으로 충분할 수 있습니다

What 9 teams took away from a competition with 800 entries

Competitions usually end at the awards ceremony. Nothing connected was left for the teams after the prize.

What I did
  • Reviewed 800 applications nationwide, selected 9 teams, and attached 2–4 mentoring sessions per team from the moment of selection
  • We placed IR pitch coaching before the presentation evaluation so the review became the result of the rehearsal
  • Assigned practitioners from global big tech and large corporates as dedicated 1:1 mentors
Results
  • All 9 teams matched 1:1 with practitioners from global big tech and major corporations
  • Closed with a public evaluation joined by some 40 residents on the citizen review panel
  • Built a structure where the connection with mentors survives the award
What we learned here

The value of a competition isn't the prize money — it's the people who remain after the review. Without that built into the design, you can review 800 entries and be left with nothing.

C-08 Founding · Fundraising Team building platform 2016– · BeginMate Inc. · Founder

A platform I built myself and raised money for myself

“I can’t find people to build with” — I hit that problem myself first. This is not someone else’s case study; it is a stretch I went through.

What I did
  • 2 patents registered for a team formation system and a project transaction service
  • Secured Venture Business, Inno-Biz and corporate R&D center certifications
  • Raised investment from a fund backed by the Korea Fund of Funds, Ministry of SMEs and Startups (2019)
Results
  • 국내외 15,000여 개사 이용 · 회원 40,000 members
  • 누적 팀빌딩 매칭 8,000건
  • 직·간접 투자 15개사 중 코스닥 상장 엑싯 2건
What we learned here

Advice from someone who has raised money is different from advice from someone who hasn't. Whether you've heard the rejection reasons first-hand is the whole of IR coaching.

FAQ

Frequently Asked Questions

Ask more →
How many sessions does it take?
There is no set number of sessions. Direction usually comes together in two or three, and we add sessions once execution starts. You can decide after the first session.
Is it okay if I don't have an idea yet?
Yes. That stage is actually the better time to meet. Changing direction after the idea is locked in costs far more.
Can it be done online?
Yes. But I recommend making the first session in person if possible. Some things never come out in words.
