Test and measurement is a thin venture market: most scaled operators sit inside Keysight, Fortive, Spectris, Ametek and the rest of the established conglomerates, so growth-stage private capital is concentrated in next-generation semiconductor metrology, RF and 5G test, analytical instruments and software-defined test platforms. The active investor pool is small and specialist.

The active investor mix runs across deep-tech specialists (Lux, DCVC, 8VC) for semiconductor metrology and analytical instruments, industrial growth funds for software-defined test and adjacent instrumentation platforms, and the corporate venture arms of the major instrumentation strategics - Bosch Ventures and similar - where strategic alignment with eventual acquirers matters. Flow has direct relationships with the specialist funds, growth investors and CVCs active in the category.

Flow has experience running VC fundraising processes for test and measurement companies across electronic and RF test, semiconductor metrology and inspection, materials and analytical instruments, environmental and emissions testing, and calibration and laboratory services. Our extensive investor network spans early-stage seed funds, growth-stage investors, and strategic and corporate VC arms.
