Partner Emeritus at Y Combinator
Check size: YC's standard investment terms are program-level, not a Kirsty-specific check size. No current personal allocation or independent angel check range is public. Applicants should use YC's application process rather than pitch Kirsty as a current selecting partner.
Kirsty's public body of work is an operating and financial framework for early-stage companies, not a personal sector thesis. She emphasizes clean formation, founder alignment, simple standard documents, frequent cash monitoring, realistic expense forecasts, cap-table understanding and raising before runway becomes critical. Her role helped YC fund and support thousands of companies consistently at batch scale.
Do not treat Kirsty as a current general-partner inbox. Apply to YC through its official process. For a legitimate finance or founder-support question, provide the company and batch if relevant, entity and cap-table status, cash balance, monthly burn, runway, financing instruments, deadlines, exact decision needed and the documents or calculations already reviewed. Never send sensitive financial data to an unverified address.
For founder-support work: teams that communicate clearly, understand their cash position, keep clean records, use standard formation and financing documents, model dilution before signing, retain ownership of financial decisions and ask for help before a problem becomes an emergency.
No current personal investment pass criteria are public. Repeated cautions in her teaching include founders who do not know burn or runway, understate expenses, scale costs ahead of evidence, outsource financial responsibility, leave formation or equity issues unresolved, or wait until only a few months of cash remain to fundraise.
Track bank balance, cash inflows, cash outflows, monthly burn and runway frequently enough to act before a liquidity problem becomes irreversible.
Use accountants and specialists for support, but keep founders accountable for understanding cash, obligations, assumptions and financing consequences.
Establish a clean entity, founder alignment, vesting, IP assignment and standard documentation early to prevent financing diligence from becoming a repair project.
Model the time needed to raise and start while the company still has leverage, instead of waiting until a few months of cash remain.
Preserve Kirsty's expertise and institutional history while routing current YC applications and investment decisions through YC's official process and live partner roster.

Founders must monitor cash frequently, forecast all expenses, avoid scaling prematurely, retain responsibility for finances and begin fundraising with enough runway.
Early-stage founders should build sound operational foundations across incorporation, founder equity, hiring and fundraising so avoidable administrative problems do not derail the company.
Founder alignment, clean formation, standard documents and an accurate understanding of ownership and financing mechanics protect the company and preserve time for building.
