From Wall Street to Unicorn: Jina Kim's Leap into Silicon Valley

Executive overview

A decade on Wall Street left Jina Kim well-paid but intellectually idle. The 9/11 attacks and Lehman Brothers' collapse forced a reckoning: she was 34, skilled, and building the wrong thing.

She drove cross-country to Silicon Valley with no job offer, found Carta (then eShares) through AngelList, and joined as the fourth employee — handling everything from lunch orders to payroll to go-to-market strategy.

Early employees at the right startup earn outsized returns by trading salary certainty for equity and responsibility.

The Wall Street exit

• Lehman Brothers offered six-figure pay and prestige — and zero intellectual engagement
• Role was purely executional: enter loan data, build models, don't have opinions
• Watching a colleague quit to co-found Lyft (John Zimmer) planted the seed
• Testifying for Lehman creditors after the bankruptcy made the cost of staying visceral
• Left at 34 with no job lined up; drove to Silicon Valley

Finding Carta

• Lived out of a coworking space (Hacker Dojo, Mountain View) to network with engineers
• Six months of rejection — Wall Street background read as a liability, not an asset
• Found eShares on AngelList; no operations role posted, applied anyway
• CEO Henry said they were full; their ops manager quit that Friday — "serendipitous"
• First task: order DoorDash lunches before 10:30 a.m. so engineers didn't get cranky

What early-stage work actually looks like

• Full ownership from day one: payroll access, customer onboarding, no playbook
• First serious mistake — sent a sensitive file to the wrong customer after one month
• CEO response: "You need thick skin. I trust you. Mistakes happen; fix it together."
• Team ethos: no one knows the right answer, so nobody penalizes honest attempts
• TechCrunch coverage on broken cap tables created momentum; 409A valuations followed as the second product

Stock options and the Wall Street mindset gap

• New York culture: focus on base salary now; options are background noise
• Silicon Valley culture: the option grant is the bet — understand your percentage
• Many Carta employees left without exercising options and regretted it
• Always ask: what percent of the company does this grant represent?
• Jina's options grew 200x since 2013; salary was cut in half when she joined

Imposter syndrome and redefining success

• Felt like an outsider as Carta scaled and specialist hires arrived
• Reframe: unique insight from a non-standard background can't be replicated by new hires
• Silicon Valley baseline assumption — crazy ideas are possible — matters more than most admit
• Success is self-defined and evolves; it's not the number society assigns
• Now building her own startup focused on helping companies reach unicorn status
