DeepMark on the record

What they shipped

  • From its YC profile: DeepMark is the authentication layer for AI voice. When an AI agent speaks, we embed a compact, machine-readable ID directly into the audio, not in metadata, which gets stripped the moment a file is touched. The ID resolves to a trust record, so a bank, a call center, or the person on the line can verify in real time who the agent is. (source)
  • Its own site describes it as: "AI-driven watermarking that embeds imperceptible identity into generated media for compliance, authentication, and trust." (source)

Who is behind it

  • Slavko Kovačević, Founder/CEO: Founder/CEO at DeepMark (YC F26). PhD candidate in Computer Science. (source)
  • Kosta Pavlović, Founder/CSO: Founder/CSO at DeepMark (YC F26). PhD in Computer Science. (source)

Code

  • GitHub organization deepmark: 5 public repositories, 22 stars in total, mostly Python; most starred is aware (12 stars, Python); last push 2026-09-09 (read 2026-09-10). (source)
