Theta Lake pricing

These figures are the AWS Marketplace price, published by Theta Lake as the seller on that marketplace; buying direct from the vendor may cost something different.

In plain terms

What you pay

  • Theta Lake charges an annual platform fee plus a charge for every person whose messages it watches.
  • The platform fee is $15,000 a year for up to 999 people, or $50,000 a year for 1,000 or more.
  • The charge per person depends on whether you keep chat, voice or video, and that number is not published anywhere.
  • Nothing about price appears on the company's own website, and once you sign up the fees cannot be canceled or refunded.

How Theta Lake pricing works

Two annual platform tiers are published on Theta Lake's AWS Marketplace listing, where it is the seller: SMB, up to 999 monitored users, at $15,000 for twelve months, and Enterprise, 1,000 users or more, at $50,000. The platform is charged per app integration. Both tiers also require a per user per year content charge by type (video, voice, chat), which is not published, so the figure is a platform floor rather than a total.

A user is a person whose communications are captured, and the same count sets the tier and the per user charge. Crossing 999 users moves a customer to Enterprise, not automatically. Fees are non cancellable and non refundable except as law requires. Theta Lake's own site shows no price, and prices are quoted after a demo. RingCentral MVP customers get archiving and eDiscovery features through that reseller.

Confidentiality and data terms: The Data Processing Addendum is published in full on the vendor's support portal and is accepted by conduct rather than negotiated; it incorporates the EU Standard Contractual Clauses and, for UK transfers, the IDTA or UK Addendum. HIPAA controls are stated as implemented and mapped through the annual SOC 2 Type II audit. No business associate agreement is published.

Note: Figures are from Theta Lake's AWS Marketplace listing, which Theta Lake writes as seller, with its own EULA and refund policy, so it is the vendor's own publication rather than a third party directory. No pricing page exists on thetalake.com. The per user per year content charge, required on both tiers, is not published.
