Products

Selected offerings — the AI products recorded here, not the vendor's full catalogue.

• RealScan Application Sold on its own

  A browser web app where analysts upload audio, video or images and get an Authentic, Suspicious or Manipulated verdict on whether the file is AI-generated, with exportable findings.

• RealAPI API service Sold on its own

  A deepfake-detection API that takes audio, video or images over REST or SDKs and returns a structured verdict on whether the media is AI-generated, with a free tier of 50 scans a month.

• RealCall API service

  Live-call detection for contact centres that tells, while the caller is still on the line, whether a voice is cloned or the caller is an AI agent, and sends that real-or-AI result with an uncertainty flag to the IVR and fraud tools, with no voice enrolment.

• RealMeeting Application

  Deepfake detection that runs inside Zoom and Microsoft Teams calls, analysing participants' video and voice in real time and alerting the host with an Authentic or Manipulated result and a confidence score, with a full report afterwards and no participant enrolment or stored recordings.

Sources

Stage, from total funding

Press release · 5 Oct 2026

"announced today that its Series A fundraising has been expanded, securing a total of $33 million in capital investment." -- company release, Oct 22, 2024 (includes the earlier $15M Series A of Oct 2023). KPMG took a minority stake in Sept 2026 with the dollar amount undisclosed (Biometric Update), so $33M is the last disclosed total, not a verified cumulative figure; any pre-Series A (seed/YC) amount is not stated in these sources.
