What's the difference between a co-founder and an early key hire, and how do I decide which I need?
A co-founder shares the risk, the ownership, and the sleepless nights, and you can't fire the relationship, only the person. An early hire brings a skill you need without the lifelong entanglement. If you mainly need one capability filled, hire for it with salary and an ESOP grant, don't hand out a third of the company. Reserve co-founder equity for someone who's genuinely building the company with you as a peer. Many founders give away founder-level equity for what should have been a senior hire, and regret it for years.

This is the single clearest articulation of the exact call you are making: equity is a counterbalance to risk, and someone taking little salary at the true zero stage (Employee #1 at effectively 10%, four-year vest) is functionally a co-founder, while a market-rate hire after you have raised belongs in the 0.1% to 5% band. It hands you concrete numbers to argue yourself out of giving away a third of the company for a role that is really a senior hire.
Once you have decided a key hire gets an ESOP grant and not co-founder shares, this is the India-specific playbook for actually doing it: pool sizing (5% to 15%), the mandatory one-year minimum vesting the Companies Act imposes, exercise price at fair market value, and the DPIIT-recognised-startup carve-outs. It is the practical alternative to over-granting equity, written for the Indian cap table you are actually running.
This is the durable reference for the structural line between a co-founder and a hire: co-founders own the company outright on day one, everyone hired afterward comes through the option pool, and even a senior non-founding CTO or VP lands in the 0.8% to 1.5% executive band, not the founder tier. Reading it makes the cost of mislabeling a senior hire as a co-founder concrete before you sign anything.
