Founder & Scenarios

When should a solo founder finally bring on a co-founder or first key hire, and how do I do it without regret?

A starting point

Add a partner when a specific, persistent gap is capping the business (you cannot sell, cannot build, or cannot scale ops) and no contractor closes it, not because you feel lonely. Test the relationship with a paid project or a real deliverable before you talk equity, and always vest over four years with a one-year cliff. Bringing someone in late means you give up less equity and keep control, which is a feature, so do not rush it out of loneliness.

Why we picked it This is the framework for the co-founder vs senior hire vs contractor decision, written from real numbers instead of theory. Pu shows that a sales contractor at 1,500 dollars a month beat the 10 percent equity sales co-founder he had given away, and a marketing contractor at 800 dollars a month beat a 10 percent equity hire. It scores five real variables (technical complexity, timing urgency, capital needs, your domain depth, personal runway) and tells you when a gap actually justifies a partner versus when a specialist on contract closes it cheaper and reversibly. It is the concrete answer to 'do I need a person, or do I need this problem solved.'

Solo Founder vs Co-Founder: The Complete Decision Framework

From Founder Reality by George Pu ~20 min read

  • Score the actual gap on five variables before adding anyone; most gaps score into 'contractor' or 'advisor', not 'co-founder'
  • Prove the role with a paid contractor first: his contractors outperformed the equity co-founders he had already given 10 percent to
  • Loneliness is not on the scorecard; add a partner only when a specific capability is capping the business

Why we picked it Most equity guides assume two people starting on day one. This one is built for exactly your situation: you started solo and are adding someone late. It gives real ranges anchored to how far you have already taken it (idea stage 40 to 49 percent, prototype 25 to 40, launched-no-revenue 15 to 30, revenue 10 to 25), so a late joiner earns less because you carried the risk. It walks the vesting math (four years, one-year cliff, you start partially vested since you already put in the work, they vest from zero), and it makes the case for a written founder agreement bluntly: of equity disputes that went unresolved, nearly every one lacked a written agreement.

How to Bring on a Co-Founder After Starting

From Equity Matrix by Sebastian Broways ~15 min read

  • The further along the business is when they join, the less equity they should get; you already absorbed the early risk
  • Standard vesting is four years with a one-year cliff, and you can start partially vested while they vest from zero
  • Put the split, roles, departure terms, and IP in a signed founder agreement; missing paperwork is where disputes fester

Why we picked it This is the India-specific playbook for exactly your situation: it names full-time versus part-time commitment as a reason to weight the split unequally, and then shows you where that gets written down under Indian law (the founders' agreement plus the SHA, with vesting and leaver provisions, and the Register of Members under the Companies Act, 2013). It also tells you to build in a formal re-split process for when the part-timer's commitment changes, which is precisely the trigger you are trying to pre-agree.

Co-Founder Equity Split in India: How to Decide, Document, and Protect It

From EquityList by EquityList 15 min read

  • Full-time versus part-time commitment at founding is a legitimate reason to split unequally, do not default to 50/50.
  • The split and vesting must live in the founders' agreement and the SHA, and be reflected in the statutory Register of Members, or investors will flag it in diligence.
  • Agree a formal process now to revisit the split and vesting when a founder's commitment materially changes, so the part-timer going full-time is documented, not argued about later.
