Boon vs Happenstance

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

Starting price

Boon

Sales-quoted

Employee referral programme software, sold on a sales quote rather than a published price.

Where Boon fits

  • TA teams rebuilding a referral programme
  • Companies that want no-login referral links
  • Enterprises comparing Teamable
  • Buyers who will take a quote

Happenstance searches the people you already know. Free is forever (chat limits, unlimited Sidedoor and connected accounts). Pro is $24/mo billed yearly.

Where Happenstance fits

  • Founders and recruiters who want warm intros from email and calendar history
  • Teams that will pool networks in a Happenstance group
  • Operators who need CSV export of people from chat (Pro)
  • Anyone who will not pay SeekOut prices just to ask 'who do you know at X'

Where they pull apart

Boon

Stands out: Referral automation with no-login employee asks: the programme TA actually wants employees to use.

Watch out: Pricing is sales-quoted. Budget from a quote.

Not the right fit for

  • SMBs hunting a $99 widget
  • Teams that already get referrals from the ATS
  • Buyers who need a published price today

Happenstance

Stands out: It is network search, not Boolean sourcing. Connect Gmail, Outlook, Google Calendar, Contacts, LinkedIn, Twitter, and Instagram, then ask in plain English who you know and why the path exists.

Watch out: Pro's $24/mo is the annual rate. API and MCP use separate credits on top of the seat. This will not find strangers outside your (and your friends'/groups') connected graphs.

Not the right fit for

  • Sourcers who need a 800M stranger graph and cold contact data
  • Buyers who want unlimited chat and MCP included in the $24 seat

Pros and cons

Boon

  • Referral automation aimed at adoption, not a dusty form
  • No-login employee experience in the product story
  • Sensible bake-off against Teamable
  • No published pricing, so every budget starts with a sales call
  • Referrals only, not an ATS
  • Value depends on employee participation rates

Happenstance

  • Free forever for Sidedoor, connected accounts, friends, and groups
  • Pro at $24/mo billed yearly, with CSV export
  • Gmail, Outlook, LinkedIn, Calendar, Contacts, Twitter, Instagram as sources
  • Only as strong as the networks you connect. No cold 800M file
  • API and MCP burn separate credits
  • Chat is capped on Free. Heavy users need Pro
