About Phishaver

Built after witnessing the attack that M365 missed.

Phishaver was founded in 2024 by Ravi Srinivasan, based in Austin, TX. We give mid-market IT teams the phishing detection capability that only large SOC teams currently have.

The founding story

While managing IT security at a prior company, Ravi Srinivasan watched a business email compromise attack almost succeed. The email was convincing — it impersonated the CFO, referenced a real vendor payment, used the right signature block, and arrived from a domain that looked legitimate. Microsoft 365 Defender passed it. The attack was caught not by any tool, but by a suspicious employee who called the CFO directly to verify before initiating the wire transfer.

The lesson was clear: rule-based email security has a ceiling, and that ceiling is well below what targeted attackers can build. LLM-based semantic analysis — the ability to score the intent and pattern of an email the way an experienced analyst would — could close that gap. Phishaver was founded to build that capability and make it accessible to mid-market IT teams who can't staff a full SOC.

Detection without mail flow disruption

No MX changes, no forwarding rules. Your email delivery path stays exactly as it is.

Analyst signal, not alert noise

High-confidence detections only. Confidence scores and detection evidence with every flag.

Privacy-first data handling

Minimal retention, read-only access, in-memory analysis. What we need to detect, nothing more.

Built for the IT team that's also the security team

Designed for organizations without a dedicated SOC — not for enterprise security programs with 20-person teams.

Four people building the detection capability that mid-market IT teams need.

Austin, TX: a real cybersecurity ecosystem

Austin is home to a genuine cybersecurity and enterprise technology community — SailPoint (identity governance), ForcePoint (data and network security), Indeed (HR/recruiting security at scale), NXP Semiconductors, and a growing cluster of security-focused startups. Phishaver is building at 111 Congress Avenue in the heart of Austin's financial-technology corridor.

Being outside the Bay Area isn't a compromise — it's an advantage. Austin's mid-market business community is our first customer base. We're close to the financial services firms, healthcare networks, and manufacturing companies who need what we're building.
