There is no 'best' structure. There is only 'best for you today, given your funding plan and turnover expectation'. Here's the framework we use with 10,000+ founders.
Solo founder, bootstrapped
Start as a Proprietorship. Zero setup cost, no ROC, easy to shut. Convert when you hit ₹40L turnover or raise external money.
Solo founder, wants credibility
OPC is your friend. Corporate PAN, limited liability, nominee mandatory. Auto-converts to Pvt Ltd at ₹2Cr turnover — plan the conversion.
2–7 founders, service business
LLP wins on compliance cost. But no ESOPs, no easy VC money. Great for consulting, agency work, professional firms.
2+ founders, product / tech / D2C
Pvt Ltd. Always. VCs won't touch anything else. ESOPs are only possible here. FDI-friendly. The ₹20–35k annual compliance is worth every rupee.
