Doppel

Primary category: anti-deepfake.

One-liner — AI-driven digital risk protection / “social engineering defense”: continuously scans the open web, social media, app stores, paid ads, domains, and the dark web for impersonation of your brand and executives — fake accounts, lookalike domains, phishing pages, deepfakes — and drives takedowns.

What it does

Doppel hunts external impersonation. Autonomous AI agents (the platform is branded “Doppel Vision”) crawl social networks, messaging apps, paid ad networks, domain registrations, and dark-web sources to find fake profiles, spoofed brands, fraudulent ads, phishing infrastructure, and deepfake content impersonating a company or its leaders, then prioritizes and pursues takedowns. The company frames the broader category as “social engineering defense (SED),” spanning brand protection, executive protection, phishing-page detection, and — via integration — deepfake media verification. It has also extended into phishing simulation, security awareness training, and email security with deepfake-driven simulations (vendor-stated). Deepfake media authentication is delivered partly through a partnership with getreal (GetReal Security) to verify videos/images/audio.

Where it sits in the stack

Sits in anti-deepfake at the foundation layer. Like adaptive-security, this is a perimeter / brand-and-people control rather than an inline AI-application guardrail — it doesn’t sit in the model/prompt path. It reduces exposure to externally-originated impersonation and phishing aimed at staff and customers — screening untrusted input at the human perimeter — but it is not an inline control inside an AI system. Trust-zone relevance: the external untrusted internet (red zone), monitoring how your identity is abused outside your perimeter.

Deployment & architecture

SaaS. The product is a monitoring + takedown service: AI agents continuously scan external channels, surface impersonation/deepfake threats in a console, and handle takedown workflows. Deepfake media verification via the getreal partnership. Integration details (SIEM/SOAR, ticketing, brand/IP feeds) not fully confirmed from the primary sources cited here.

Positioning & differentiators

Positioned as the AI-native digital-risk-protection (DRP) / social-engineering-defense platform, distinguished by autonomous-agent scanning breadth (social, ads, domains, dark web) and Fortune 500 traction in financial services, energy, tech, healthcare, and media (vendor-stated). Differs from adaptive-security, which points inward (training your own employees) — Doppel points outward (finding others impersonating you). Differs from pure media-authentication vendors reality-defender, getreal, and pindrop: Doppel is a monitoring-and-takedown service that consumes deepfake detection (partnering with GetReal) rather than being primarily a detection engine. CrowdStrike CEO George Kurtz invested personally in the Series C (vendor-stated).

Ownership, funding & M&A

Independent, VC-backed. No acquisition (seed carried no M&A flag; none found). Founded 2022; HQ San Francisco; co-founders Kevin Tian (CEO) and Rahul Madduluri (CTO), both ex-Uber engineers.

Funding, confirmed against primary/reputable sources:

  • Series B — $35M, led by Bessemer Venture Partners (with 9Yards Capital, Sozo Ventures); brought total to ~$54.4M at ~$205M valuation (SecurityWeek).
  • Series C — $70M, announced 2025-11-19, led by Bessemer Venture Partners, at >$600M valuation; total funding $124M (Doppel press release). Returning investors include a16z, South Park Commons, Script Capital, 9Yards, Sozo, Strategic Cyber Ventures; new investors include George Kurtz and NTT DOCOMO Ventures.

CTO / hedge-fund lens

Day-2, medium fit. Brand/executive impersonation — fake “fund” accounts soliciting investors, spoofed domains, deepfake videos of a portfolio manager promoting a scam — is a genuine reputational and fraud risk for asset managers, and DRP/takedown is the control for it. But it’s an external-brand-protection service, not part of the internal AI-application security stack, and is most valuable for firms with a public-facing brand and retail/investor surface; a small, low-profile fund may not need it. No direct SR 11-7 / model-risk relevance. Evaluate against incumbent DRP vendors (ZeroFox, Netcraft, Recorded Future, BforeAI) — not yet covered here.

Competitors / alternatives

  • adaptive-security — inward employee training/simulation vs Doppel’s outward impersonation monitoring.
  • getreal — deepfake media authentication; a Doppel partner for media verification as well as a category neighbor.
  • reality-defender, pindrop — deepfake/synthetic-media and voice detection.
  • Incumbent DRP vendors (ZeroFox, Netcraft, Recorded Future) — not yet covered here.

Open questions / to verify

  • Exact founding details and whether HQ is San Francisco vs Covina, CA (sources vary; SF is the operating HQ).
  • Integration set (SIEM/SOAR, ticketing) and how takedown SLAs work.
  • Scope/depth of the GetReal partnership vs native deepfake detection.
