Official Firstbase Pricing (2026): $399 Formation, $299 Agent Autopilot, Virtual Address, and Tax Add-Ons

Firstbase searches are mostly current-pricing and alternatives searches: founders want to confirm the official $399 formation entry point, the $299 annual Agent Autopilot cost, whether Firstbase.io includes a virtual address or mailroom, and which alternatives are cheaper if they do not need bundled bookkeeping or tax filing yet.

Current official Firstbase.io pricing: $399 for formation plus $299 per year for Agent Autopilot, with virtual-address, mailroom, bookkeeping, and tax add-ons priced separately.

Quick answer
  • Current official Firstbase pricing in 2026 starts at $399 for formation

  • Agent Autopilot / registered-agent coverage: $299 per year

  • Virtual address and mailroom workflows are separate add-ons, not included in the $399 formation price

  • Firstbase.io pricing is most useful for founders who want bundled back-office services, not just formation

  • Bookkeeping starts at $189+ per month and tax filing at $1,799 per year

  • Best fit: founders who want a bundled back-office vendor more than a founder workflow platform

  • Founders who mainly want formation pricing and early-stage founder tools should compare Firstbase alternatives before paying for ops add-ons.

SparkLaunch uses a $499 base incorporation workflow price and separates filing fees or registered-agent arrangements when needed. Firstbase lists incorporation at $399 and Agent Autopilot at $299 per year.

Free cap table

Firstbase routes founders toward separate equity tooling. SparkLaunch includes a basic cap table from the start.

Start before you incorporate

Founders can validate the idea and prep the company before paying for formation, which is useful for earlier-stage teams.

SAFE and dilution tracking

SparkLaunch supports core early-stage equity modeling directly instead of sending founders to a separate vendor.

Why choose Firstbase

Full back-office suite

Firstbase extends beyond formation into mailroom, bookkeeping, tax, and compliance services for startups that want a bundled ops stack.

International-founder depth

Firstbase markets heavily to international founders and remote teams who need more operational infrastructure.

Mailroom and address workflows

If you need a U.S. virtual address or mailroom workflow immediately, Firstbase has the stronger offer today.

Bundled service model

Frequently asked questions

The public Firstbase entry price used in this comparison is $399 for formation, with Agent Autopilot at $299 per year and additional charges for services like mailroom, bookkeeping, and tax filing.

The current public Firstbase.io pricing surface used here starts at $399 for formation and $299 per year for Agent Autopilot. Virtual address, mailroom, bookkeeping, and tax filing sit outside that base price, so founders should model the add-ons explicitly.

Firstbase lists Agent Autopilot at $299 per year. Founders comparing alternatives should include that recurring cost, not just the formation headline price.

No. Firstbase treats virtual address and mailroom coverage as separate add-ons rather than bundling them into the $399 formation price. That distinction matters for founders searching Firstbase pricing because the back-office total can rise quickly.

The formation headline prices are close, but the total cost depends on whether you need Firstbase mailroom, bookkeeping, tax filing, or Agent Autopilot add-ons. SparkLaunch is the simpler founder-tooling choice; Firstbase is the more operations-heavy stack.

The best Firstbase alternatives depend on what you actually need. SparkLaunch is stronger when you want incorporation, cap table basics, SAFE tracking, CRM, and founder workflow in one product path. Founders who mainly want outsourced back-office services may still prefer Firstbase.

Firstbase is more established around international-founder operations and address/mailroom needs. SparkLaunch still supports formation for international founders, but it is not positioned as a back-office outsourcing vendor.

Many earliest-stage startups do not. If your books are still simple, it can be smarter to defer premium bookkeeping until transaction volume justifies it.

Yes. A founder could use Firstbase for operational services and SparkLaunch for cap table management, fundraising prep, or founder workflow tools.
