Simplify's Take
What believers are saying
- September 9, 2026 Series A raised $10 million from MiddleGame Ventures and Elkstone.
- ZeroRisk said revenue triples in 2026 as contracted programmes move into deployment.
- February 17, 2026 Longford hiring for 80 roles expands delivery capacity and customer support.
What critics are saying
- Bank dependence is acute; losing Bank of America or Global Payments would damage credibility fast.
- Risk orchestration is crowded; legacy PCI vendors and acquirer in-house tools can compress margins by 2027.
- If deployment stalls, the 2026 revenue tripling story collapses and Series A dilution dominates.
What makes ZeroRisk unique
- ZeroRisk unifies merchant cyber risk, PCI compliance, remediation, and education in one platform.
- Bank of America and Global Payments validate its acquirer-focused workflow in 2026.
- Founded in 2023, ZeroRisk targets portfolio-wide risk visibility across hundreds of thousands of merchants.

Image: ZeroRisk The company's platform aims to help payment processors and retailers manage and reduce cyber risk. Irish cybersecurity and compliance company ZeroRisk has raised $10m in a Series A funding round led by MiddleGame Ventures with participation from existing investor Elkstone. The company aims to help payment processors and retailers manage and reduce cyber risk by uniting "risk monitoring, compliance, education, guided remediation and protection services in one platform". It offers payment processors "a single view of cyber risk across the hundreds of thousands of retailers using their payment processing technology", and provides individual retailers with "clear guidance on the risks that matter to their business and the steps they can take to address them", according to the company. ZeroRisk said the new funding would be used to support its expansion globally, further its product development, and increase operational capacity to deploy the platform across large merchant portfolios of major payment providers. Co-founder and CEO Gary Nolan said: "Payment companies have spent years trying to manage merchant risk through annual compliance exercises. "That is no longer enough. Their customers are dealing with scams, credential theft, website vulnerabilities and attacks on devices every day. "ZeroRisk has moved from proving the product to deploying it at scale. This investment will allow us to expand the team, deepen the platform and support the payment providers that have chosen to build their next-generation of merchant cyber programmes with us." The company works with European and North American customers including Bank of America, Global Payments, Checkout.com and Trust Payments. Patrick Pinschmidt, a co-managing partner at MiddleGame Ventures, said: "The ZeroRisk team brings a unique combination of commercial and technical expertise, reinforced by working hand-in-hand with leading payment providers." ZeroRisk, which was founded in 2023 and has Irish operations in Dublin and Longford, and a US office in Atlanta, said it "expects to grow revenue threefold in 2026 as contracted programmes move into deployment and its international customer base grows". The Irish company, co-founded by Nolan, Francesco Consiglio and Marco Borza, raised $4m in February 2025 in a round led by Elkstone, whose head of venture Niall McEvoy said of the new funding: "The commercial progress in a short period of time has been impressive, and this Series A funding round further validates investor confidence that ZeroRisk can deliver transformational change in the sector globally."

As former operators in the space, they understand the fundamental pain points firsthand and have built technology that transforms a critical financial services workflow, making it more intuitive and seamless for payment providers and merchants alike. We're thrilled to be partnering with Gary and the team as they build the new standard for this critical function." Niall McEvoy, Head of Venture at Elkstone, said: "Elkstone first backed ZeroRisk at seed stage when Gary and the team presented their compelling vision on where the merchant cybersecurity and compliance space was heading. The commercial progress in a short period of time has been impressive, and this Series A funding round further validates investor confidence that ZeroRisk can deliver transformational change in the sector globally. We are pleased to deepen our support alongside new investor MiddleGame Ventures."
