Stripe Atlas is the stronger choice for a Delaware C corporation intended to raise US venture capital, because the equity documents and cap-table setup are what investors expect. Firstbase is better if you want a lower entry price, a modular back office you can grow into, or an LLC rather than a startup corporation.

The entity decision drives everything
Before comparing prices, settle the structure. If you intend to raise from US venture investors, they will almost certainly expect a Delaware C corporation with a clean cap table, founder vesting and 83(b) elections filed on time. That is the product Stripe Atlas was designed to deliver.
If you are building a business you will fund from revenue, a C-corp brings double taxation and formality you do not need. An LLC is usually the better vehicle, and Firstbase handles that comfortably alongside a back office you can extend.
Getting this wrong is expensive in one direction. Converting an LLC into an investable C-corp later means legal fees, potential tax consequences, and a formation history investors have to read through. Over-forming as a C-corp when you never raise mostly costs unnecessary filings - annoying but recoverable.
Price versus what you get
The $399 versus $500 gap is small enough that it should not decide this. What differs is the shape of the spend. Atlas front-loads a complete startup incorporation and then leaves you with a modest annual agent fee plus Delaware's obligations. Firstbase starts lower but expects you to add the address, tax and compliance services you need, each of which recurs.
For a founder who wants only the entity, Firstbase is cheaper. For a founder who needs equity documents and 83(b) support, Atlas is cheaper than assembling that separately with a startup lawyer, which routinely costs more than the $500 fee alone.
Both leave Delaware's costs untouched: a $300 flat franchise tax for an LLC, or the corporation franchise tax for a C-corp, due annually. Neither provider absorbs that, and it is a common year-two surprise for founders who only budgeted the formation price.
- Atlas: higher one-off, lower ongoing, investor paperwork included.
- Firstbase: lower one-off, ongoing cost depends on add-ons you keep.
- Delaware franchise tax applies either way.
Rejections, refunds and support
Atlas fees are non-refundable, including where an application is declined - and declines do happen, sometimes with limited explanation. If your business model, industry or country profile is unusual, that is a real risk to weigh before paying.
Firstbase operates a short refund window measured from purchase, and once the state filing is submitted that work and the state fee are genuinely spent. The more common Firstbase complaint is not rejection but cost surprise: founders expecting the headline price and paying materially more once add-ons and renewals are included.
Support expectations should be modest with both. Treat them as business-hours email services, keep your own copies of every document, and diarise your own deadlines regardless of which you choose.
What neither one does for you
Neither can guarantee a US bank account. Both may make introductions, but Mercury, Relay and others apply their own country policies and risk checks, and non-residents from some countries are declined regardless of formation route. Confirm banking eligibility for your residence country before paying anyone.
Neither removes your federal filing obligations. A foreign-owned single-member LLC generally files Form 5472 with a pro forma 1120 annually, even when dormant, with penalties starting at $25,000. A C-corp has its own return obligations.
And neither can speed up the IRS. Non-residents without an SSN or ITIN apply for the EIN on Form SS-4 by fax or phone, and processing commonly takes several weeks. Build your launch plan around that, not around the formation certificate.
What each actually costs over three years
Ignore the $399 versus $500 headline and model the whole period. With Atlas you pay once, then carry the registered agent at roughly $100 a year plus Delaware's obligations - a flat $300 franchise tax for an LLC, or the corporation franchise tax for a C-corp. Three years in, the total is predictable and fairly modest.
With Firstbase the formation fee is lower, but the recurring picture depends on which add-ons you keep. A registered agent renews. A business address renews. Tax and bookkeeping services renew. A founder who keeps three add-ons can quietly pass the Atlas three-year total while a founder who keeps none stays well below it.
Then price what Atlas includes that Firstbase does not. Founder equity documents, vesting terms and 83(b) election support from a startup lawyer routinely cost more than $500 on their own. If you genuinely need that paperwork, Atlas is not the expensive option - it is the cheap one, and comparing it to a bare formation fee is comparing different products.
The reverse is equally true. If you will never raise, that equity infrastructure is worth nothing to you, and paying for it is pure waste. This is why the entity decision has to come before the price decision.
- Atlas: higher one-off, lower and more predictable ongoing.
- Firstbase: lower one-off, ongoing cost scales with add-ons kept.
- Equity paperwork is the real value gap, and only if you need it.
Changing your mind later
Switching provider is easy; switching entity type is not. If you form an LLC through Firstbase and later need an investable Delaware C-corp, expect a conversion or fresh incorporation with a share exchange, handled by a lawyer, at a cost that dwarfs either formation fee. Investors also read formation history, and a messy one invites questions.
Going the other way is cheaper but wasteful: a C-corp you never fund still owes annual filings and franchise tax, and unwinding it costs a dissolution. Neither error is fatal, but the first is materially more expensive.
If you truly cannot predict whether you will raise, the pragmatic move is the lower-commitment entity now with a diarised review in twelve months. Just make the review real, because the cost of converting rises as soon as you have revenue, employees or a co-founder with equity expectations.
Do these three checks before you pay either
- Banking eligibility first. Neither provider can guarantee a US account. Check which banks accept your country.
- Model the three-year cost. Year two is where founders get surprised. See the full cost breakdown.
- Know your filing obligations. Foreign-owned LLCs generally file Form 5472 even when dormant. Check your obligations free.
Buyer questions
Firstbase vs Stripe Atlas FAQ
Firstbase vs Stripe Atlas - which is better for a Delaware C-Corp startup?
Stripe Atlas is generally stronger for a Delaware C-corp intended for US fundraising, because founder equity documents, 83(b) support and a clean cap table come as standard. Firstbase is better if you want a lower entry price, an LLC, or a modular back office you can extend with tax and bookkeeping.
Is the $100 price difference meaningful?
No - $399 versus $500 should not decide this. What matters is what each includes. Atlas bundles investor-ready equity paperwork that would cost more from a startup lawyer; Firstbase bundles less upfront but lets you add services selectively. Compare on structure and three-year cost.
Does Firstbase offer startup perks and credits like Atlas?
Partner offers vary by provider and change frequently. Startup credit programmes are commonly tied to C-corporations rather than LLCs. Check the current offer pages directly rather than relying on any third-party summary, including this one.
Can I get a refund from either?
Atlas fees are non-refundable, including where an application is declined. Firstbase operates a short refund window from purchase, and work already filed with the state - plus the state fee itself - is not recoverable. Screenshot your checkout total either way.
Which handles the EIN faster for a non-resident?
Neither has an advantage. Without an SSN or ITIN, the application goes in on Form SS-4 by fax or phone, and IRS processing for international applicants commonly runs several weeks. No provider can bypass that queue.
What if I am not sure whether I will raise money?
Starting with an LLC through a lower-commitment route keeps costs down and can be restructured if plans change, though conversion has legal and tax costs. If a raise is genuinely likely within 12-18 months, forming the C-corp correctly at the start is usually cheaper than converting later.
Which is better value over three years?
Atlas is more predictable: one fee, then roughly $100 a year for the agent plus Delaware's obligations. Firstbase can be cheaper if you keep no add-ons, or more expensive if you keep several, since each renews. Compare the three-year totals for the exact services you would actually retain.
Do I need the 83(b) election support Atlas provides?
If you are a founder receiving restricted stock in a C-corp, the 83(b) election is time-critical with a strict filing window, and missing it can create a significant future tax problem. It is genuinely valuable for startup founders and completely irrelevant for a single-member LLC.
Can non-residents use Stripe Atlas?
Yes, non-US founders form through Atlas regularly. But applications can be declined, the fee is non-refundable, and a US company never guarantees banking or payment-processing approval - those are separate assessments based on your residence country and business model.
Which is better for an ecommerce or Amazon FBA business?
Usually Firstbase with an LLC, since ecommerce sellers rarely raise venture capital and benefit more from a modular back office. Be aware that US inventory - including FBA warehouses - can create state tax and sales-tax nexus obligations that neither provider resolves for you.
