Head to head

Circa vs SixFifty

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

Circa

Sales-quoted

Circa is still sold as Mitratech Circa for OFCCP-style job distribution, ESDS posting, veteran outreach documentation, and diversity recruiting. Pricing is sales-quoted. Mitratech has owned Circa since 2023.

Where Circa fits

  • Federal contractors that still need ESDS posting and outreach files
  • HR compliance teams documenting veteran and disability recruiting efforts
  • Employers that want Circa because it already sits in a Mitratech stack
  • TA ops that need audit-ready job-distribution logs, not a new ATS

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

Circa

Stands out: It automates state ESDS job-bank postings and documents good-faith outreach across a claimed 15,000-plus community organizations. Dashboards track applicant flow and outreach for audit files.

Watch out: US OFCCP affirmative-action rules were rolled back in 2026, so the compliance pitch has changed even though the product is still on the price list. There is no self-serve rate card. Ignore Capterra's $600/mo starting price.

Not the right fit for

  • Companies that only need a cheap job board with no compliance archive
  • Buyers who need a published monthly price before a sales call

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

Circa

  • ESDS posting and outreach documentation in one Mitratech product
  • Capterra 4.4 from 29 reviews on Mitratech Circa
  • ATS-adjacent rather than a rip-and-replace ATS
  • The vendor does not publish a price on circaworks.com
  • OFCCP mandate rollback in 2026 weakens the original buying reason for some US employers
  • Diversity job distribution still competes with broader programmatic networks

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
