Should I quit as a solo founder or wait until I have a co-founder locked in?
The short answer
Do not quit your job to go hunting for a co-founder; that is the most expensive way to run a search. Quit solo only if you can carry the company alone for 12 months, or find your co-founder while you are both still employed and de-risk with a 3 month paid trial project before either of you resigns. A co-founder you met last month is a liability, not a safety net: many startups die from co-founder splits, not market failure.

Why we picked it
This is the exact trial-before-you-quit framework your answer prescribes, written by someone who ran it: Lin dated six candidates over a year while employed, ran two-week prototype sprints with each (build an MVP for consumer ideas, do customer interviews for enterprise), and only committed to Joel Poloney (now Siteline) after a structured 50-question review. It proves you can find and de-risk a co-founder without either person resigning first.
Run a timeboxed two-week build sprint with a candidate before any commitment, working chemistry shows up in shipped work, not coffee chats
Keep your non-negotiables to a maximum of three and separate table-stakes from must-haves from flex areas
Treat finding a co-founder like hiring an executive, the relationship outlasts most marriages, so search deliberately and do not stop early out of loneliness

A concise checklist of the five founder qualities that matter most, useful for calibrating your own mindset and spotting where to grow. Primary source, zero fluff.
Why we picked it
This is the citable source for the claim at the heart of your answer: Noam Wasserman's research across 10,000+ founders found 65% of high-potential startups fail from co-founder conflict, not market failure. It is the hard number that justifies refusing to rush a pairing, and it names the specific fault lines (leadership, money, credit, blame) so a founder knows what the paid trial and the 50 questions are actually stress-testing for.
65% of high-potential startup failures trace to co-founder conflict, the relationship is the biggest single risk you control
Teams of friends, family, and couples fail most because they dodge hard conversations to protect feelings, so surface the money and control talks early
The predictable conflict zones are leadership, equity, strategy, and credit, settle these in writing before you commit, not after
