OpenEntity vs Firstbase US LLC Formation for Non-Residents, Compared

Firstbase's headline is $399 and OpenEntity's is $499 — but the real question is what's actually included. Here's an honest, like-for-like breakdown for non-resident founders.

Disclosure: OpenEntity is our own service, so we have an interest in your decision. We've tried to keep this comparison fair — Firstbase is a strong, well-regarded product and we credit its genuine advantages below. All Firstbase figures are as of June 2026 and may have changed; please verify current pricing on firstbase.io before deciding.

The Short Answer

Firstbase Start advertises a $399 one-time formation fee, which is $100 cheaper than OpenEntity's $499. But that $399 covers formation only: a registered agent (Firstbase Agent, from $299/yr) and a US business address (Mailroom, from $35/mo) are sold separately. OpenEntity's $499 is all-inclusive — formation, EIN, one year of registered agent, a US address, and a banking introduction are bundled in. Once you add the pieces every non-resident actually needs, a like-for-like year-1 comparison usually puts OpenEntity at or below Firstbase's true total. If you specifically want à-la-carte modularity and don't need an address, Firstbase can still come out ahead. Both work without an SSN or ITIN.

The True Year-1 Cost: A Like-for-Like Comparison

A fair comparison has to put the same things on both sides of the table. Almost every non-resident founder needs four things in year one: state formation, an EIN, a registered agent, and a US business address. Here's what each provider costs once you add the pieces that a real, operational company requires. We've used Firstbase's lowest published add-on prices, so this is a conservative, Firstbase-favorable estimate.

Year-1 componentOpenEntityFirstbase
Formation + state filing + EIN + operating agreementIncluded in $499$399
Registered agent (1 year)Included+$299 (Firstbase Agent, from)
US business address (1 year)Included+$420 (Mailroom @ $35/mo × 12)
Banking introductionIncludedIncluded (Mercury application)
True year-1 total$499 year 1~$1,118 year 1

The takeaway isn't that Firstbase is expensive — it's that a $399 headline and a $499 headline aren't comparing the same product. Firstbase's $399 is a clean, low formation-only price; OpenEntity's $499 is a bundle. If you don't need a US address (some founders use their own), Firstbase's true cost drops substantially and the two get much closer.

EIN & Banking: Where Each Provider Is Strong

For non-residents, two things make or break a US company: getting an EIN without an SSN, and actually opening a bank account. Both providers handle these well, with slightly different strengths.

OpenEntity — Bundled and Predictable

OpenEntity obtains your EIN on an expedited basis, typically in 3–5 business days, with no SSN or ITIN required. Banking is handled as a guided introduction to Mercury, Relay, or Wise, with a 95%+ approval rate among eligible applicants (approval always depends on your profile, country, and business activity — no provider can guarantee a bank's decision). Because the registered agent, address, and compliance calendar are all in the same package, there are fewer moving parts to coordinate after formation.

Firstbase — Strong EIN Handling and Integrated Mercury

Firstbase has a genuinely strong EIN process: it acts as (or works through) an IRS-authorized third party to obtain your EIN with no SSN/ITIN, and its Mercury banking application is tightly integrated into onboarding. Officially the EIN takes "a few days," though some customer reviews report longer waits, with at least one founder describing a delay beyond 45 days — turnaround for foreign owners can vary with IRS workload. Note also that Mercury tightened its eligibility and review criteria across 2025–2026, so approval is not guaranteed for either provider. Firstbase's modular add-on model is a real advantage if you want to pick exactly what you pay for.

Firstbase's Strengths and Limitations, Fairly Stated

We don't think Firstbase is the wrong choice — for many founders it's an excellent one. A fair comparison means naming what it genuinely does well alongside the trade-offs of the Start tier. Here's our honest read.

Where Firstbase Genuinely Shines

  • A low, transparent one-time formation price — $399 is one of the cleaner headline numbers in the market.
  • Strong no-SSN/ITIN EIN handling through an IRS-authorized third party, designed specifically for foreign founders.
  • Tightly integrated Mercury banking application built directly into onboarding, which streamlines the path to an account.
  • A modular add-on model: you pay only for the services you actually want, which suits founders who already have an address or agent.
  • Broad reach — Firstbase serves founders across 191 countries with a mature, well-reviewed onboarding flow.

Where the Start Tier Has Trade-Offs

  • The $399 covers formation only — a registered agent (from $299/yr) and US address (from $35/mo) are billed separately, so the real year-1 cost is well above the headline.
  • Compliance and annual-report support aren't part of the Start tier; you manage those yourself or add them.
  • Non-resident tax filing is a separate $899/yr service rather than a bundled feature.
  • EIN turnaround is officially "a few days," but some reviews report longer waits — including one founder who described a delay beyond 45 days.
  • Mercury tightened its eligibility and review criteria across 2025–2026, so banking approval is never guaranteed (the same caveat applies to OpenEntity).

None of these are dealbreakers — they're simply the shape of an unbundled product. If you want à-la-carte control, they're features, not flaws. If you'd rather have everything in one predictable package, that's where OpenEntity's bundle is designed to help.

Which Should You Choose? An Honest Verdict

There's no universal winner. The right pick depends on whether you value a single all-inclusive price or à-la-carte flexibility — and whether you need a US address.

Choose OpenEntity if you...

  • Want one all-inclusive price with registered agent, US address, and EIN bundled — no surprise add-ons
  • Prefer predictable year-2 maintenance (~$209/yr) over separately-billed line items
  • Value a compliance calendar, lifetime support, and a money-back guarantee
  • Need a US business address and don't want to source one yourself

Choose Firstbase if you...

  • Want the lowest possible formation-only price ($399 one-time) and will add services as needed
  • Prefer modular, à-la-carte add-ons so you only pay for what you use
  • Already have a US address (or don't need one) and want to skip that cost
  • Value Firstbase's strong no-SSN/ITIN EIN handling and tightly integrated Mercury onboarding

Bottom line: if you need a fully operational company — formation, agent, and address — OpenEntity's all-inclusive $499 is usually competitive with or cheaper than Firstbase's true year-1 total. If you only need bare formation and will add the rest yourself, Firstbase's $399 is hard to beat on headline price. Both are legitimate, non-resident-friendly choices.

OpenEntity vs Firstbase — FAQ

Is Firstbase really cheaper than OpenEntity?

On the headline number, yes: Firstbase Start is $399 one-time versus OpenEntity's $499. But Firstbase's $399 is formation only — a registered agent (from $299/yr) and a US address (from $35/mo) are extra. Once you add the registered agent and address that most non-residents need, OpenEntity's all-inclusive $499 is typically competitive with or cheaper than Firstbase's true year-1 total. Verify current Firstbase pricing on firstbase.io, as figures here are as of June 2026.

Can both form a US LLC without an SSN or ITIN?

Yes. Both OpenEntity and Firstbase are built for non-residents and obtain your EIN without an SSN or ITIN. Firstbase serves founders in 191 countries; OpenEntity also forms LLCs for non-residents with no SSN. The EIN is obtained through an IRS process designed for foreign owners.

How long does the EIN take?

OpenEntity targets 3–5 business days on an expedited basis. Firstbase officially quotes "a few days," though some reviews report longer waits — in one reported case more than 45 days. EIN turnaround for foreign-owned entities can vary with IRS processing times regardless of provider.

Is OpenEntity biased in this comparison?

OpenEntity is our own service, so treat this as our perspective and verify the details yourself. We've tried to be fair: Firstbase is a strong product with a low transparent formation price, excellent no-SSN/ITIN EIN handling, integrated Mercury banking, and flexible modular add-ons. The main caveat we raise — that its $399 covers formation only — is a pricing-structure observation, not a criticism of quality.
