Mentor Roles

Find the Role That Fits You.

Nexus recruits three distinct types of contributors. Each serves a different function for the founding teams. Mentors are active for roughly 10 weeks and work directly with startups based in Japan. All 40 spots are reviewed by invitation and referral.

Lead Mentor

Hands-On Coaching

Paired directly with a startup. You meet with your founders every three weeks, ask hard questions, challenge assumptions, and stay close to execution. No monthly decks, no passive feedback: your job is to be in the details and push the team forward. Suited for entrepreneurs who have raised capital or built a company to significant scale.

Board Advisor

Strategic Guidance

Provide strategic direction on customer targeting, market positioning, and company direction. Monthly sessions with assigned teams. More teacher than coach: debate directly, give clear recommendations, and push founders toward the decisions they are avoiding. Best fit for experienced founders or VC partners with at least one full market cycle.

Expert

Workshops and Office Hours

Run content workshops, hold open office hours, or take one-off introductions on a topic where you have deep expertise. 3 to 5 hours per quarter, no ongoing commitment required. Best fit for operators, executives, researchers, and domain scientists who want real access without a recurring calendar obligation.
