From Ballet To Breach Prevention: How A Magician’s Son Raised $4.2M In Seed Funding For His Cybersecurity Startup

Editor’s note: The following is the latest profile in a series of articles profiling startup founders from non-traditional, non-technical backgrounds who have successfully launched venture-backed enterprises. Read earlier interviews in this series featuring MagicSchool AI founder Adeel Khan here, Trunk Tools founder Sarah Buchner here, Tabs founder Ali Hussain here, Craft founder Ilya Levtov here, GC AI founder Cecilia Ziniti here, and Incredible Health co-founder Iman Abuzeid here.

Long before William “Will” Cielen began developing advanced cybersecurity technology, he performed regularly inside his father’s professional magic shows.

Raised by a magician father and an acrobat mother, Cielen spent his early childhood years living aboard a cruise ship prior to spending another five years residing in Las Vegas. By age 10, his family relocated to Montreal, where he enrolled in a rigorous ballet curriculum that required him to train through the morning hours and attend regular school in the afternoons.

“I was rather introverted as a child, but I became extroverted through the unique upbringing,” Cielen remembers.

By age 15, he had skipped two full grades of school, entered college courses, and successfully established a website design and development enterprise. A subsequent journey to a hackathon held in Waterloo served to connect him directly to venture capital investors. During that very week, Cielen recounted, he chose to depart from his studies, left an algorithmic trading internship behind, and traveled immediately to San Francisco to launch Hilt.

Today, the cybersecurity startup is emerging from stealth mode to exclusively announce to Crunchbase News that it has secured $4.2 million in seed financing designed to assist organizations in identifying and halting irregular data behaviors, including the unauthorized extraction of sensitive corporate information.

Array Ventures spearheaded the latest financing round, with participation from Verdict Capital, Base10 Partners, Brickyard, Liquid 2 Ventures, Sequel, the Sarah Smith Fund, and Alumni Ventures. This recent capital injection lifts Hilt’s aggregate funding to $4.7 million, following a prior $500,000 pre-seed investment round directed by Pear VC in October 2025.

Finding the problem

Upon touching down in San Francisco as Hilt’s co-founder and CEO, Cielen had committed to the cybersecurity sector, yet he still needed to pinpoint the exact industry pain point worth solving. His background included attending Concordia University located in Montreal alongside serving as an algorithmic trading intern for the National Bank of Canada.

“I had to do a lot of customer discovery,” he explained regarding his extensive outreach to evaluate the marketplace and converse with prospective clients “to see what the real problems were, not to build in the dark.”

A major breakthrough arrived in January during a discussion with the chief technology officer of a prominent hedge fund, who detailed severe security challenges impacting high-frequency trading networks. Because those specialized infrastructures operate within microsecond timeframes, Cielen pointed out that traditional security programs introducing latency simply cannot be tolerated.

The hedge fund subsequently proposed a prospective contract valued between $1 million and $2 million contingent on Hilt successfully resolving the issue, according to Cielen. The client then disbursed a significant six-figure advance payment prior to Hilt even constructing the final product.

Hilt’s proprietary software tracks data flows across cloud architectures, local computers, and enterprise networks, establishing distinct behavioral norms for individual users and system resources. It flags aberrant patterns—even when executed by authorized personnel—while maintaining claims that it operates without impairing system speeds.

As an illustration, a late-night login event might remain entirely routine for a staff member who frequently pulls extra hours. However, if an individual whose standard routine is strictly daytime-only suddenly authenticates access at midnight right after modifying their login credentials, Hilt can identify that combination as potentially malicious.

The platform possesses the capability to notify corporate security personnel to review the situation or, under specific conditions, isolate the activity instantly as it unfolds.

“They don’t have to wake up and see that it happens, but we can actually stop it as it happens,” Cielen noted.

The startup’s methodology relies on operating directly at the kernel layer—the core foundation of an operating system—and transmitting activity telemetry into graph neural networks, a specialized form of artificial intelligence built to spot anomalies. Cielen emphasized that this architecture grants Hilt visibility beneath distinct software programs utilized by clients, enabling seamless deployment across diverse computing environments.

Furthermore, he noted that performance metrics recorded by at least one client indicated that activating Hilt actually accelerated their existing cloud architecture.

The firm maintains an active working relationship with the original hedge fund client alongside a second high-frequency trading entity, according to Cielen. He stated that the organization’s total client roster doubled during the thirty-day window following a more aggressive marketing campaign, though exact client metrics were withheld.

Hiring and expanding beyond finance

Beyond traditional trading institutions, Hilt is attracting strong commercial interest from neobanks, healthcare enterprises, professional services groups, and other entities handling confidential data. End users operate the software directly inside their proprietary technological infrastructure, ensuring total ownership over corporate data while compensating the startup via an annual subscription calculated per data collector.

The emerging enterprise currently maintains an 11-person team, including co-founder and Chief Technology Officer Alex Genest and founding engineer Zin Bitar. Although initially anchored in San Francisco, the startup relocated its operations to Chattanooga, Tennessee, alongside investor Brickyard to accelerate its path toward solid product-market alignment.

Cielen indicated that the freshly secured funds will be allocated primarily toward recruiting top-tier talent and expanding brand awareness.

“The money is very useful for hiring the best people,” he stated.

Investor POV

Shruti Gandhi, general partner at Array Ventures, remarked that the majority of existing security utilities typically fall into two categories: they attempt to predict sensitive assets ahead of time “and get it wrong a lot, or they tell you what happened after the data is gone.”

“Hilt can find and stop these breaches in real time, with accuracy,” she expressed via email communication. “It also runs entirely inside the customer’s own environment, so nothing leaves the company. For a bank or government entity, that is the difference between proactive vs. reactive response.”

She also emphasized that modern security breaches frequently avoid looking like traditional cyberattacks.

“They look like normal activity such as an employee using valid access, a connected vendor, or an AI agent doing what it’s allowed to do,” she stated. “Hilt connects these actions and detects when normal behavior becomes suspicious. As AI agents increasingly interact and act autonomously, we think this problem will only grow, and we wanted to get ahead of it.”

Niko Bonatsos, founder and managing director at Verdict Capital, noted that his decision to fund Hilt was primarily driven by admiration for its leadership.

“At Verdict Capital, we back founders who are obsessed, have high velocity and are learning animals,” he wrote in an email. “Will exemplifies these traits.”

Bonatsos, a former investor with General Catalyst who established Verdict early in 2026 and also backed Mercor, explained that Hilt’s technical approach stood out immediately, adding that Hilt represented one of the very first investment tickets issued by his new firm.

“Most security tools look at content: files, signatures, known threats. Hilt looks at how data moves, at the kernel, which is the one place you can’t hide from,” Bonatsos stated. “Everyone assumed you couldn’t sit that deep without slowing systems down. They did it in live financial environments… Selling security into banks is about as hard as enterprise sales gets, and I watched them do it.”
