Seezo
AI-native platform that automates security design reviews and threat modeling directly from engineering architecture documents.

Seezo automates security design review (threat modeling) using generative AI. It ingests design documents from tools like Confluence, Google Docs and Jira, then generates threat models covering threat actors, data flows, trust boundaries and attack paths, mapping each to concrete security requirements that flow back into Jira, Slack or GitHub. A companion “Seezo Agent” lets engineers ask security questions inside their existing workflow rather than filing a ticket and waiting on an AppSec reviewer.
The structural difference from legacy threat-modeling tools (manual diagramming tools, static templates) is that Seezo treats design review as a continuous, AI-driven process tied to the documents engineers already write, aiming to close the coverage gap where most new features ship without any security design review at all because expert reviewers can’t keep pace with engineering velocity. Seezo was founded in 2023 in Bengaluru by Sandesh Mysore Anand (ex-AppSec at Cigital and Razorpay) and Rakshitha R Rao, and raised a seed round reported at roughly $5-7M, led by Accel, disclosed in late 2025.
Innovation Matrix Assessment
Moved from its core Security Design Review (SDR) product to an in-workflow "Seezo Agent" within about two years of founding, and raised an Accel-led seed round in 2025, suggesting fast product-market iteration.
Directly targets a known AppSec operational gap — most features ship without any security design review because expert reviewer time doesn't scale — and plugs into tools (Jira, Slack, Confluence) security and engineering teams already use.
Real institutional backing (Accel) and named customers (Ascot Group, Razorpay, Sidekick Security) per the company's own case studies, but still a small team (roughly 11-50 people) with sources disagreeing on whether the round was seed or Series A.
Applying generative AI to automate threat modeling meaningfully changes a traditionally manual, expertise-bottlenecked process, but it is an evolution of an existing discipline (threat modeling/secure design review) rather than a wholesale redefinition of application security.
No independent benchmark, analyst test or named security-incident evidence was found; the available customer references (Ascot Group, Razorpay, Sidekick Security) are vendor-published case studies without third-party corroboration or outcome metrics.
As AI-accelerated development widens the gap between feature velocity and manual security review capacity, automated design review tools address a durable and likely growing need, though competition from larger, better-funded ASPM vendors is a real risk.
Why CISOs Should Care
Lets a CISO extend security design review coverage to engineering teams that currently ship features with no review at all, without proportionally growing AppSec headcount.
What Makes It Different
Generates threat models and security requirements automatically from the design docs engineers already produce, rather than requiring a human expert to run a manual threat-modeling workshop.
The Matrix Verdict
58/100 — INCREMENTAL INNOVATOR
An Incremental Innovator: a genuinely useful, well-targeted application of generative AI to a real AppSec bottleneck, backed by a credible investor, but still early-stage with no independent efficacy evidence yet and a founding/funding story that varies by source.
Editorial Note: Claims vs. Verified Findings
The founding year (2023) and founders are consistent across Inc42 and other profiles, but the funding round's size ($5.3M-$7M), stage (seed vs. Series A) and date (September vs. November 2025) vary by source; Accel's own post calls it a seed round. Customer outcomes are vendor-published case studies, not independently verified.
