The answer, as recorded

The right answer splits hard on one question: are you raising venture capital, or are you building a business that funds itself? They point to completely different products. ## If you're on the VC track (Delaware C-corp) **1. Clerky** - What I'd recommend for anyone who actually intends to raise a priced round. It generates lawyer-quality incorporation, founder stock, 83(b), IP assignment, and SAFE documents, and it's built around the sequence that startup lawyers and diligence actually expect. The trade-off worth knowing: it doesn't file with Delaware for you on the basic tier - you handle that or pair it with another service. Roughly $799 versus $5,000-$15,000 for a law firm doing the same papers. **2. Stripe Atlas** - The fastest path from zero to an incorporated company with a bank account and payments live, typically 1-3 days. Best if you need to *start collecting money* immediately. Weakness: essentially no ongoing compliance support, tax help, or reminders after formation - Atlas hands you a company and walks away. **3. Harvard Business Services (DelawareInc.com)** - The unglamorous pick. Delaware-only since 1981, cheap registered agent, and they don't upsell you into a subscription. Good if you already know exactly what you want filed and just need a competent filer plus a long-term agent. A common and genuinely good combination is Atlas or HBS for the filing plus Clerky for the equity and financing documents. ## If you're forming an LLC / self-funded business **4. ZenBusiness** - Best all-around for a first-time founder. Formation plus the surrounding scaffolding (registered agent, compliance calendar, domain/site/email) in one place, and the onboarding assumes you've never done this before. **5. Bizee (formerly Incfile)** - The budget option: $0 base plan plus state fees, free registered agent the first year ($119/year after). Fine filings; expect upsells. **6. LegalZoom** - Worth the premium only if you want attorney and tax consultations attached to the same account. Otherwise you're paying brand tax. **7. MyCompanyWorks** - Niche but real: same-business-day processing on orders before 3 p.m. ET, included free on every plan rather than sold as expedite. **One I'd steer around:** Firstbase markets itself as a full company "operating system," but there's a pattern of reported filing delays, support failures, and missed compliance deadlines. For something as unforgiving as a franchise tax deadline, that's the wrong place to economize. **The thing that bites founders isn't the filing.** It's the 83(b) election - 30 days from stock issuance, no extensions, and missing it can cost you a large tax bill years later. Clerky handles this deliberately; most LLC-oriented services don't touch it because it isn't relevant to their typical customer. If you incorporate a C-corp anywhere, calendar that date the same day you file.
