Sydney-based Deteqt raised $5 million in seed funding to scale quantum magnetometer chips for GPS-denied military navigation, led by Main Sequence with participation from ATP Fund, BOKA Capital, Beaten Zone Venture Partners, Uniseed, and University of Sydney.
The defence tech startup, spun out of the University of Sydney's Nano Institute in March 2025, builds chip-scale quantum sensors using diamond-on-silicon for applications including drone navigation in jammed environments, mineral exploration, and portable medical imaging. The company already has a contract with the Australian Defence Force.
What this means for sales teams: Defence tech seed rounds in this range typically precede commercial hiring by 60 to 90 days. Deteqt's leadership includes CEO Dr. Jim Rabeau, co-founder Professor Omid Kavehei, and COO Rupal Ismin. No VP Sales or CRO announced yet. The company is pre-revenue and R&D-focused.
Defence tech sales roles in ANZ have increased 40% year-over-year as Silicon Valley investors pour capital into Australian strategic tech. Companies like Anduril and Shield AI are actively recruiting in the region, with enterprise AE roles typically starting at $140k base, $220k OTE for defence sector experience.
Deteqt's technology addresses a validated military need: quantum magnetometry was reportedly used to locate a downed US Air Force pilot in Iran by detecting heartbeat magnetic signatures from distance. The startup's chip approach aims to miniaturise this capability for drones and autonomous vehicles.
The funding will advance product development, scale diamond chip manufacturing, and grow the team. Worth noting: defence sales cycles run 12 to 18 months with multiple procurement stakeholders. Early-stage defence tech companies often hire technical sales engineers before traditional AEs.
Competitors in quantum sensing for defence include international players, though Deteqt's CMOS-compatible manufacturing approach targets lower production costs. Main Sequence's repeat investment (following a $750k pre-seed in March 2025) signals confidence in commercial trajectory.
For sales professionals watching the defence tech space: this is a small, technical sale with long cycles and high deal values. Not a volume play. If Deteqt posts roles, expect deep technical requirements and security clearance needs.
