A network that works.
Now we scale it.RankShield Series A — turn a live, verifiable, post-quantum AI security network into the default evidence layer.

To take a network that already works and make it the default evidence layer for AI security. The capital funds three things: hardening the six OS guardians and the agent runtime from their current, varying stages to general availability; scaling the federated threat mesh and the post-quantum attestation layer that are already live; and building the go-to-market motion from the self-serve WordPress and Shopify install base into enterprise. We discuss the specific round size and terms directly with investors rather than posting them publicly.

Shipped and revenue-capable: the WordPress plugin (live on wordpress.org with paid Stripe tiers), the Shopify app (listed on the App Store), the post-quantum attestation stack (sign, multi-algorithm, transparency log, independent verify, with witness co-signing), five live vertical sites, and a production threat mesh that has mapped 238 attack networks from ~887,000 real events since June 17, 2026. Built but pre-launch: six OS guardians on one shared core at genuinely varying readiness, a prompt-injection-resistant agent runtime, and a cross-pillar enterprise fleet. Drafted or filed: patents in financial and legal (filed) and medical and robotics (drafted). We keep those three buckets separate on purpose.

The plan weights toward product and go-to-market, because the technology and network are the parts already proven. Indicatively: product and engineering (harden guardians and the agent runtime to GA) is the largest slice, followed by go-to-market (convert the self-serve base and build enterprise sales), then network and platform (scale the mesh, federation, and evidence layer), then compliance and IP (certifications and patent prosecution), with an operating reserve. Exact figures are set with the round and shared in diligence.

Concrete and measurable: bring the strongest guardians (Windows, Linux) to general availability and launch iOS in the App Store; scale the mesh’s coverage and harden its enrichment so the attack-network map is broader and more complete; ship the agent runtime and attestation API into first enterprise pilots; grow the paid and enterprise-fleet install base from the existing WordPress and Shopify footprint; advance patent prosecution on the filed financial and legal families and file the drafted medical and robotics ones; and publish an independent third-party security review. These are the targets the round is sized against, stated as a plan, not a promise.

Real ones, which we would rather name than have you find. This is a fast-moving, well-funded category, so competitive and timing risk is genuine; the "underserved intersection" we occupy is an inference, not a proven monopoly, and warrants a freedom-to-operate check. Product readiness varies across the six guardians, so execution risk is concentrated in getting them to GA. We are pre-scale on revenue. And a signed receipt on its own is well-trodden prior art, so our defensibility rests on the network effect and the operator-independent evidence layer, not on any single primitive. We think the honest version of the story is the strong version.

Reach out through the contact page and we will share the deck, the data room, the specific round terms, and access to verify the live network and attestation stack yourself — which, for a "verifier, not vendor" company, is rather the point. We would rather you check the claims than take them on faith.
