SerenX discloses $2.3M offering a year after first sale

Why it matters

The filing reveals previously undisclosed capital behind Hasbrouck's counter-drone startup, while leaving its investors, security terms, customers and independently verified field performance unknown.

Scott Hasbrouck, the repeat founder behind Florida counter-drone developer SerenX, disclosed a $2,305,500 private securities offering more than a year after the first investor committed capital.

The Form D filed with the SEC says the offering was fully sold to six accredited investors, with no sales commissions or finder fees. The first sale occurred on August 27, 2025. CFO Norman Forbes signed the notice on September 2, 2026, and the filing appeared in EDGAR on September 3.

The filing arrived nearly a year after the first sale, meaning the disclosure is new while the underlying financing is not.

The notice describes the securities as an option to acquire securities, rather than equity or debt. It does not identify the investors, valuation, price per security or the type of security an investor can acquire. SerenX reported the full $2,305,500 as sold, leaving no amount remaining.

SerenX was previously incorporated as Orcrist, Inc., the name it still uses for its products and public website. Florida corporate records show a name-change amendment filed on June 4, 2026. The Form D lists Hasbrouck as an executive officer and director, Serge Glushenko as a director and Forbes as an executive officer.

A software founder moves into interceptors

Hasbrouck's route into defense hardware began with consumer and enterprise software. He built the PaperDesk iPad note-taking app, later co-founded education software developer Ginkgotree and participated in Y Combinator's Summer 2016 batch as a co-founder of home technology support service Techmate. Y Combinator profiled Hasbrouck and co-founder Colin Barceloux during that batch.

Hasbrouck subsequently described himself as CTO of Sivo, a fintech infrastructure developer from Y Combinator's Winter 2021 batch. His public biography also credits him with software architecture work involving NASA and U.S. defense research, along with work on satellite systems and non-terrestrial 5G communications.

SerenX traces its founding thesis to Hasbrouck's late-2024 trip through Arctic Norway. According to SerenX's account, he concluded that small GPUs had become powerful and compact enough to put computer vision and autonomous guidance inside a man-portable interceptor. He founded Orcrist in February 2025.

That origin story explains the central product bet: replace large launch infrastructure and expensive interceptors with autonomous systems that individual operators can carry and deploy quickly.

The $2.3M backs a compact counter-drone bet

SerenX's website describes a 2.8-kilogram electric counter-drone interceptor as field-ready. The company's SEAM-1 page describes the interceptor as throwable or shoulder-fired.

SerenX says onboard computer vision and inertial guidance allow the interceptor to acquire and pursue targets without an external data link or GPS. SerenX currently describes the system as using precision kinetic defeat.

Those performance and readiness claims come from SerenX. Publicly available independent test reports, procurement documents or customer contracts do not establish its targeting performance or field readiness. SerenX also says it reached Technology Readiness Level 6 in October 2025 after demonstrating a prototype in a relevant operational environment. The identities of the operators and the conditions of that demonstration are not disclosed.

SerenX has also published plans for HALYX, a liquid barrier concept intended to intercept projectiles.

SerenX says it reached its initial readiness milestone with zero venture capital. The Form D confirms outside securities financing but does not identify the six buyers as venture firms. SerenX's zero-VC description may refer to investor type, or to development completed before some or all of the offering was funded. The filing does not provide enough detail to settle that distinction.

Counter-drone procurement is moving faster

Hasbrouck entered a counter-drone market where buyers are actively testing systems with different methods of defeat. Dedicated interceptors compete with automated gun systems, electronic warfare and high-power microwave weapons.

The U.S. Army says JIATF-401 signed a $500 million Domestic Shield counter-drone contract. The program illustrates the scale of the procurement market SerenX is entering.

Capital has followed those procurement programs. Allen Control Systems, which builds the automated Bullfrog weapon station, said in June that it raised a $200 million Series B at a $2.2 billion post-money valuation. Epirus fields Leonidas, a high-power microwave system designed to counter drones and swarms.

SerenX is pursuing portable kinetic interceptors with a financing round that is small by current defense technology standards. Its public materials describe multiple interceptor systems and the HALYX concept. Hasbrouck's software background supports the autonomy thesis. The harder work remains in testing, manufacturing and procurement, where performance claims have to survive government evaluation and repeated field use.

The late Form D has now exposed the capital behind Hasbrouck's first year of development. It does not reveal who funded SerenX, what the investors received or whether its interceptor has moved from field demonstrations into paid deployment.
