Episode notes
Early Jobs Taught Grit And 'Figure It Out'
- Mark Langer peeled shrimp and filleted fish during a Christmas break at age 13, working 10–11 hour days for about $3/hour.
- That early hard work from his mother taught him grit, grind, and a "figure it out" mentality that shaped his career choices.
Post 9/11 Pivot Led Him Away From Big Corporates
- After 9/11 Mark lost an Arthur Andersen internship and got a last-minute summer job at Johnson & Johnson, moving to Princeton and finding an apartment by going door to door.
- The experience showed him he couldn't thrive at a large corporate environment and pushed him toward middle-market banking.
Thrown Into Deploying Capital In Africa
- Compass tasked Mark to present a plan to deploy $50M in Africa with only weeks to prepare, then sent him to South Africa and Zimbabwe for on-the-ground work.
- He interviewed State Department and ex-CIA contacts, met managers and public companies, and learned to operate independently in risky environments.
