The start-up has developed an Inference Platform which it says can help businesses scale AI securely.

Irish-led US start-up CalypsoAI has secured $5m in funding after making it to the final round of a cybersecurity innovation competition.

The company, which was founded in 2018 and is headquartered in Dublin and New York, provides security and compliance solutions to its clientele. It is led by Irishmen Donnchadh Casey as its CEO and James White as its president and chief technology officer.

CalypsoAI was selected from among “hundreds” of submissions at this year’s RSAC Innovation Sandbox to be one of ten finalists for the title of cybersecurity’s boldest innovator. The competition, in its 20th year, has been a launchpad for emerging players in the cybersecurity industry.

Now, the start-up will take to the stage during the RSA Conference in San Francisco at the end of the month, making a three-minute final pitch to a panel of judges.

According to CalypsoAI, the funding will help it scale “even faster”, enabling it to advance its R&D, expand its reach and continue building its inference-layer security platform.

The start-up contested in this year’s Innovation Sandbox with its Inference Platform, which, according to CalpysoAI, provides companies real-time visibility and enforcement at decision-making points.

According to the company, the platform continuously tests, observes, and defends AI systems in both training and post-training environments, helping security leaders stay ahead of threats, meet governance requirements and scale AI responsibly.

“CalypsoAI is addressing the most urgent challenges that enterprises face in securely scaling AI,” said Casey

“Our world-leading solutions give companies the confidence to innovate without exposing themselves to risk. This recognition from RSAC reinforces CalypsoAI’s position as the clear and trusted leader in AI security.”

Earlier this year, the company released a “comprehensive world first” security index designed to assess the safety of generative AI (GenAI) models and expose critical vulnerabilities.

The index is powered by CalypsoAI’s Inference Platform Red-Team and compares the safety, cost and capabilities of a wide range of major GenAI models based on real-world security testing.

“We’re growing our technology team rapidly to create unique AI-powered security products that empower safe and secure AI adoption,” White said.

“With this investment, we will accelerate the launch of several key innovations already in the pipeline.”

In June 2023, CalypsoAI established its Dublin centre of excellence, announcing intentions to more than double its Irish workforce from a team of 20 to a team of 50 by 2025. And late last year, it announced the expansion of these plans with the aim of hiring 50 more staff in the areas of engineering, data science, marketing, sales and operations.
