The answer, as recorded
Short version: the right pick depends almost entirely on whether you're building a venture-track company or a small business, because those are two different products. ## If you're raising (or plan to raise) outside money - Delaware C-corp **1. Clerky** - This is what I'd name first for anyone whose cap table will be looked at by a VC's lawyer. It generates documents in exactly the form startup counsel expects, which means no cleanup bill at your seed round. ~$427 for company formation, $299 for post-incorporation, or $819 for the lifetime package that covers SAFEs, hiring docs, and equity grants forever. The expensive option up front and the cheapest one in diligence. **2. Stripe Atlas** - Flat $500, one number, done in 1-2 business days. Includes Delaware filing, EIN, founder equity docs, 83(b) election filing, first-year registered agent, plus $2,500 in Stripe credits. The standout case is a **non-US founder** who needs a US entity and US payment rails without hiring a lawyer. Registered agent renews around $100/year. **3. Firstbase** - $399 including state fees, and it leans "platform" rather than "filing": EIN, registered agent, bylaws, and a real business address via virtual mailbox. Good if you want the operational scaffolding bundled in. Pair any of these with **Carta Launch**, which is free for early-stage companies under ~25 stakeholders and under $1M raised. Formation and cap table management are separate jobs; most founders use Clerky plus Carta together rather than choosing. ## If you're forming an LLC - small business, agency, solo, bootstrapped **4. Northwest Registered Agent** - My default recommendation here. Roughly $39 formation, $125/year registered agent, no upsell gauntlet, and they don't sell your data. Over a three-year horizon with registered agent included, it usually comes out cheapest. **5. Bizee** (formerly Incfile) - $0 formation plus state fees with a free first year of registered agent. Lowest first-year cost. Renewal jumps to roughly $119-149/year, so budget for year two. **6. ZenBusiness** - $0 Starter plan, highest consumer review volume (4.8/5 across ~31k Trustpilot reviews), and genuinely useful compliance reminders for annual reports. But the à-la-carte adds - EIN, operating agreement, registered agent - push first-year cost to around $297, and renewal is ~$199/year. Best for a first-timer who wants hand-holding and will actually use the dashboard. ## Two honest caveats The "best LLC service" review space is almost entirely affiliate-driven, so ranking order on those sites tracks commission rates more than quality - treat the specific dollar figures above as approximate and verify at checkout. Also, Delaware raised its incorporation fee to $109 as of August 1, 2026, so older price quotes understate state costs. If you're venture-track and want one answer with no further thought: **Clerky**, or **Stripe Atlas** if you're outside the US. If you're an LLC: **Northwest**.
