Overview
Flusso designs CMOS MEMS flow and environmental sensors for high-volume markets using a fabless model, outsourcing manufacturing to scale production. Its flagship FLS112 mass flow sensor and FLS122 air velocity sensor, along with plug‑and‑play modules FSE-112 and FSE-122, integrate on a CMOS MEMS platform and fit in small packages to measure mass flow, volumetric flow, differential pressure, and temperature. The company differentiates itself through a scalable production approach, Cambridge-origin sensor expertise, and a strategy that combines academic leadership with a global manufacturing footprint secured via a 2022 acquisition, while keeping its brand and team. Flusso aims to enable energy-efficient flow sensing in compact, cost-sensitive products such as smart inhalers, HVAC systems, and filtration units, and to grow its high-volume manufacturing capacity worldwide.

Simplify's take
What believers are saying
- Mike Whittingham joined in September 2023, signaling a push toward scaled commercial execution.
- The company’s October 2026 team page shows active leadership and ongoing hiring momentum.
- FLS122 targets HVAC, data-center, and consumer-air markets with immediate efficiency and filtration needs.
What critics are saying
- Flusso’s only disclosed capital raise remains 2020; growth now depends on customer revenue.
- Sensor commoditization from Sensirion, Honeywell, and STMicroelectronics can crush pricing by 2027.
- If gas-sensor launches stall, Flusso stays niche and risks becoming an acquisition-only asset.
What makes Flusso unique
- Cambridge-born fabless CMOS MEMS platform fits tiny, board-mounted flow-sensing applications.
- FLS112 and FLS122 pack mass-flow, pressure, temperature, and air-velocity sensing into 3.5mm packages.
- Shanghai Sierchi’s 2022 acquisition added manufacturing reach without changing Flusso’s brand or team.
