Head to head

AirMason vs SixFifty

Same facts, side by side: starting price, free tier, MCP, API and what each one is actually built for.

AirMason

$999/yr Free trial

AirMason is a digital employee-handbook platform. Startup for 1 to 99 employees is $999 per year, or $149 per month if billed monthly. Small Business for 100 to 199 employees is $1,499 per year or $199 per month. 200-plus employees is enterprise quote.

Where AirMason fits

  • US and multi-state employers that want a branded, searchable handbook employees actually open
  • HR teams collecting e-signatures and audit trails without a full HRIS policy module
  • Companies with under 100 employees that will pay $999/yr instead of a lawyer-only Word file
  • Ops teams that will import employees through REST or SAML rather than retyping the roster

SixFifty

Sales-quoted

Multi-state employee handbooks and HR policies built on Wilson Sonsini expertise. Pricing is a quote from headcount and the number of states you operate in.

Where SixFifty fits

  • US employers hiring across several states that need handbook language kept current
  • In-house HR and legal teams that want redlined updates when laws change
  • HR consultants who need a multi-client employment-docs workspace
  • Companies expanding into new states that want offer letters, NDAs, and contractor agreements in the same library

Where they pull apart

AirMason

Stands out: Unlimited digital handbooks, signatures, versioning, and reminders sit on Startup. Employee import via CSV, REST, and SAML is on the plans table, with SSO called out as included.

Watch out: Annual billing saves up to 44 percent versus monthly. Copywriting, creative services, content migration, and automated policy updates are add-ons. A dedicated account manager is not on Startup.

Not the right fit for

  • A five-person shop that only needs a free Word handbook download
  • Enterprises that need attorney-of-record policy drafting as the core SKU rather than an add-on

SixFifty

Stands out: Subscriptions include unlimited users, a handbook builder covering all 50 states, and locality coverage for places such as San Francisco, Chicago, New York City, and Seattle.

Watch out: sixfifty.com/pricing asks you to contact sales for a quote. Cost scales with employee count and state count, so a one-state shop and a 20-state shop will not pay the same.

Not the right fit for

  • Teams that need a printed monthly rate on the website before a call
  • Employers outside the US whose policies are not US state and city labor law

Pros and cons

AirMason

  • Published $999/yr Startup floor for 1-99 employees
  • REST, SAML, and SSO on the plans table, not a hidden enterprise toggle
  • Capterra 4.8 from 14 matching AirMason reviews
  • Monthly Startup is $149, so skipping annual more than doubles the year
  • Legal drafting, design, and automated law updates are add-ons
  • 200-plus employees leaves the published table for a custom quote

SixFifty

  • Unlimited users on standard subscriptions
  • Handbook and policy coverage that names specific cities, not just states
  • Automated legal updates and a research module in the same product
  • No public dollar grid. Quotes depend on headcount and state count
  • Capterra's SixFifty listing has no verified reviews
  • The vendor is explicit that the product is not a substitute for your own attorney
