Consulting

We go a long way together

Consulting · Advisory →

A lecture ends after one meeting. Consulting stays with the company until it reaches the next stage. From 1:1 mentoring to joining as a part-time C-Level — only as much as you need.

↗Mentoring

1:1 Startup Mentoring

We start by defining whether what is stuck is the team, the business model, or funding. Delivered as session-by-session engagements.

↗Growth Strategy

Growth Strategy Consulting

We rebuild the business model, the organizational and HR structure, and the funding roadmap on a project basis.

↗IR Coaching

Fundraising · IR coaching

We take the IR deck and business plan apart through a reviewer's eyes, then add pitch rehearsals.

↗Fractional C-Level

Part-Time C-Level · Resident Advisor

The agreed hours are spent inside the company. It is a seat that takes responsibility for execution, not advice.

↗Public Advisory

Public-sector policy advisory · Program design

I design accelerator programs, competitions, and Demo Days so that results remain.

Why Younsub Jung

One person,
four seats at once

The people who build, the people who evaluate, and the people who operate are usually different people. I founded a company in 2016 and still run it, review other founders’ business plans, design incubation programs for local governments and public institutions, and teach at a university. Every program is built only from what I have actually experienced in those four seats.
