The short answer
SPLIT.IO *EXPERIMENTATION is an authorized software subscription charge from Split Software Inc. (a Harness company) for feature flag management, continuous delivery toggles, and product experimentation.
Why Split.io Charged Your Account
An invoice entry displaying SPLIT.IO *EXPERIMENTATION indicates an authorized business software charge for a Split Feature Management & Experimentation Platform subscription. Split Software Inc. (acquired by Harness) provides developer tools for feature flagging, continuous delivery toggles, and data-driven product experimentation. Engineering teams use the platform to safely release software updates to specific user cohorts, and active cloud licenses appear on corporate statements under this descriptor.
Billing is structured around Monthly Tracked Keys (MTKs) and developer seat licenses, with charges recurring monthly or annually. Unexpected billing increases frequently occur when web or mobile applications exceed contracted MTK traffic limits, triggering automated overage fees. Reviewing billing settings within the developer console provides itemized records of active keys and tier usage.
If your engineering department does not utilize this developer tool, verify whether a product manager or developer provisioned workspace access using a company card. To review subscription tiers, inspect monthly active keys, or cancel platform licensing, sign in to your administrator dashboard online. Cardholders suspecting unauthorized billing should contact their finance department or bank immediately. Keeping close track of your monthly statements ensures complete financial security and prevents unexpected surprises from recurring charges.

Can MTK overage charges be refunded?
