Ciphero
AI Verification Layer for Enterprise
Last verified August 17, 2026 · Updated daily
What Ciphero is building
Ciphero builds an AI verification layer for enterprise environments, a system that captures, checks, and governs every AI interaction that occurs inside an organisation, whether human-initiated or agentic. As enterprise AI adoption has accelerated, the number of interactions with tools like ChatGPT, Copilot, Claude, and internal AI agents has exploded, and most security teams have no visibility into what data those interactions are touching or what those models are returning. Ciphero installs a sovereign control layer across all of it: auditing inputs and outputs in real time, flagging policy violations, detecting prompt injection attacks, verifying outputs against internal truth sources, and surfacing shadow AI usage that legacy DLP tools and static firewalls cannot see. The platform tracks behaviour across employees, models, and agent-to-agent interactions simultaneously, and enforces governance policies dynamically rather than through static rules. The pricing model is flat, not usage-based, which removes the friction that causes enterprise security buyers to throttle adoption.
Why this matters
The numbers the company cites are not marketing estimates. They are the kind of figures that land in a CISO's quarterly review: 80% of enterprises show signs of shadow AI activity, one in six data breaches this year was traced to unauthorised AI usage, and 97% of organisations have no proper AI access controls in place. Enterprise AI governance barely existed as a compliance category eighteen months ago. Now it is in the top three items on every CISO's agenda in financial services, healthcare, legal, and government. Ciphero's founders built Fakespot, a detection and verification system for fake reviews and counterfeit listings, which Mozilla acquired in 2023. The underlying capability - identifying when an AI-generated or AI-mediated output is not what it claims to be - is exactly what Ciphero applies to enterprise AI interactions. This is not a pivot. It is the same detection architecture applied to a much larger and faster-growing threat surface.

Oversubscribed pre-seed with 8 people total. Capital earmarked for product development, design partners, and enterprise rollout. First 2-3 hires will define the company.
Working at Ciphero
Founded in , Ciphero is AI Verification Layer for Enterprise. They're now <50 people. Working at a AI company at this stage means broad remit, direct access to founders, and equity that still means something if the company works out.
The majority of roles are in New York.
How to actually get hired at Ciphero
Why applying the normal way doesn't work
Ciphero is <50 people. No recruiter, no HR. Your application goes to a founder juggling everything. Cold outreach is how you actually get seen.
Who to contact at Ciphero
Founding team
Khalifah and Gross built Fakespot from the ground up, scaled it to millions of users detecting fake reviews and counterfeit product listings at scale, and sold it to Mozilla in 2023. That exit is proof that this team can build adversarial detection systems that are accurate enough for a major browser company to acquire and embed in a product used by hundreds of millions of people. The capability they are bringing to Ciphero is the same one Mozilla paid for - redirected at a faster-growing and higher-value threat surface.
Rob Gross co-founded Fakespot alongside Khalifah and led operations through the Mozilla acquisition. His operational experience scaling a detection platform to millions of users translates directly to the enterprise deployment challenges Ciphero faces.
Sen Tian's title, Chief AI Intelligence Officer, is deliberate. It signals that the AI detection technology is being treated as a first-class product asset and not a feature bolted onto a security platform. At a company of eight people, the CAIO title means the technical architecture of the AI verification layer is Tian's domain and responsibility entirely.
What to show them
Ciphero's core technical challenge is building detection systems that can classify AI interactions as compliant or non-compliant at enterprise scale, in real time, across a wide range of AI tools with different output formats, token structures, and behavioural patterns. This is a hard adversarial detection and classification problem. The false positive rate is the hardest part: flag too much and enterprise security teams disable the tool; flag too little and the governance layer has no teeth. Core skills: security engineering with experience in enterprise DLP, CASB, or network security; familiarity with LLM behaviour and prompt injection patterns; ability to build adversarial detection systems that operate reliably under distribution shift; experience with policy enforcement at scale. Exposure to AI red-teaming, jailbreak research, or output verification is directly relevant. For proof of work, build a prompt injection detection demo: write a Python classifier that takes a set of LLM input/output pairs and flags likely prompt injection attempts, data exfiltration patterns, or policy violations. Use publicly available jailbreak datasets (AdvBench, JailbreakBench) as your test set. Post it on GitHub with a README that specifically addresses the false positive problem at enterprise scale.
A cold email that works at Ciphero
What Ciphero screens for
The oversubscribed round is a signal of unusual investor conviction at pre-revenue stage. Sovereign's Capital manages $780M+ and doesn't chase hype. Chingona Ventures' Samara Hernandez specifically called out the team's enterprise credibility as the investment rationale. Bullpen Capital specialises in post-seed bridge rounds for companies building toward large enterprise exits. Hustle Fund backs operators who move fast. Both lead investors are backing the team as much as the product, which means the founders will be deliberately selective about who joins and why.

Don't make these mistakes
Don't send generic AI enthusiasm. Be specific, be brief, attach proof of work. At pre-seed with eight people the founders are making every hire personally, and a cold email with a GitHub link or a named account list will be read the same day it lands. Reference the Fakespot/Mozilla acquisition - it's the credibility anchor that proves this team can build adversarial detection systems at scale.
