Firstbase.io pricing: $99 Start plus recurring add-ons

Firstbase.io Pricing 2026: $99 Start, $299 Agent, and Add-Ons

This independent SparkLaunch comparison is not Firstbase.io's official website. It covers Firstbase.io pricing and services, the current $99 Start entry point, the $299 annual Agent Autopilot cost, where founders should check the official Firstbase.io pricing page, whether Firstbase includes a virtual address or mailroom, how Doola and Clerky differ, and which alternatives fit founders who do not need bundled bookkeeping or tax filing yet.

Firstbase Start is currently $99; Agent is $299 per state per year. Mailroom, accounting, tax filing, and Firstbase One are priced separately, so model the full service stack you need.

Quick answer
  • Start: $99 one-time for Delaware or Wyoming formation; the pricing page also displays a crossed-out $399 prior price

  • Agent: $299 per state per year for registered-agent and compliance services

  • Mailroom starts at $35/month; Premium is currently $50/month or $350/year

  • Firstbase One is $199/month billed annually and bundles Agent, Mailroom Premium, Accounting, and Tax Filing after formation

  • Start does not include every recurring back-office service, so compare the full annual cost

  • Alternatives buyers usually compare SparkLaunch, Clerky, Doola, Stripe Atlas, and Firstbase

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

Why choose SparkLaunch

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.

Why choose Firstbase

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.

Frequently asked questions

The public Firstbase entry price used in this comparison is $99 for Start, with $399 visible as prior pricing and Agent Autopilot at $299 per year. Virtual address, mailroom, bookkeeping, tax filing, and other back-office services are separate purchases, so the Start price is not the full operating cost. Founders should compare only the services they actually need and distinguish one-time formation work from recurring address, compliance, accounting, and tax expenses. This is an independent SparkLaunch breakdown, not Firstbase.io's official site; confirm current packages and eligibility directly with Firstbase before buying.

The current public Firstbase.io pricing surface used here shows Start at $99, $399 as prior pricing, and Agent Autopilot at $299 per year. Virtual address, mailroom, bookkeeping, and tax filing sit outside that base price, so founders should model the add-ons explicitly.

The public Firstbase.io pricing and services surface used here starts with Start at $99 and Agent Autopilot at $299 per year, while virtual address, mailroom, bookkeeping, tax filing, and other operations services are separate add-ons. That is why founders comparing alternatives should model both the headline formation price and the recurring service stack.

No. This page is an independent SparkLaunch comparison, not the official Firstbase.io website. Founders who want the source pricing page should verify packages directly on Firstbase.io, then use this comparison to separate the current $99 Start price from Agent Autopilot, mailroom, bookkeeping, tax, and alternative options.

Firstbase.io pricing starts with formation, then layers services such as Agent Autopilot, virtual address, mailroom, bookkeeping, tax filing, and compliance support. Founders comparing alternatives should separate the formation price from recurring service add-ons.

The Firstbase LLC formation pricing and company-formation comparison point used here starts with the public $99 Start price, while $399 appears as prior pricing. The recurring and optional add-ons, including Agent Autopilot, virtual address, mailroom, bookkeeping, and tax filing, should be modeled separately.

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 $99 Start price. That distinction matters 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. Clerky is more legal-document-led, Doola is more back-office-led, and Stripe Atlas is more formation-and-perks-led. Founders who mainly want outsourced back-office services may still prefer Firstbase.

Firstbase is strongest when the buyer wants a broader operations bundle around formation. Clerky is stronger for startup legal-document workflow, Doola is closer to Firstbase on back-office positioning, and Stripe Atlas is strongest when Stripe credits, partner perks, and a formation-first purchase are the main draw.

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.
