What Actiflow does

Actiflow BV is a privately held Dutch engineering consultancy specializing in fluid dynamics, founded in March 2005 by Eric Terry and Roy Campe as a spin-off from the Faculty of Aerospace Engineering at Delft University of Technology. The company is headquartered in Breda, Netherlands, and operates with a team of 11-50 engineers and consultants combining expertise in Computational Fluid Dynamics (CFD), wind tunnel testing, and field measurements. Its work spans three practice areas: Wind Engineering (pedestrian wind comfort, wind loading, large-scale urban wind assessments, pollutant dispersion, urban climate, real-time wind maps, windmill biotopes), Indoor Climate and Air Quality (cleanrooms, datacenters, offshore platforms, operating rooms, parking facilities, offices, sports venues, production facilities), and Aerodynamics for R&D (automotive, fans and turbines, HVAC systems, food processing, maritime, medical equipment, oil and gas, sports).

The company's core technology is CFD simulation supported by an in-house HPC cluster, complemented by wind tunnel testing (via partners including Imperial College London) and on-site field measurements. Actiflow has productized portions of its expertise into two software offerings: the Actiflow Wind App (providing real-time wind maps and short-term forecasts to ports and airports, with API integration) and the Online Wind Assessment Tool (self-service preliminary wind comfort studies for building designers). Notable deliverables include aerodynamic design of the Koga Kinsei track bike (25% drag reduction, 11 Olympic medals across Tokyo and Paris Games) and co-development of the "Actiflow System" aerodynamic technology licensed to Ferrari for the 599XX.

Actiflow generates revenue primarily through professional services (consultancy) complemented by subscription and licensing income from its Wind App and assessment tools. It operates a sales-led, expert-consultation go-to-market with direct client engagement via contact forms, dedicated sales email, and Wind App demo requests. Customer concentration spans enterprise clients across real estate, construction, engineering consulting, healthcare, automotive, sports, data centers, and government sectors across Benelux, the UK, Gibraltar, and the Middle East. The company has remained bootstrapped and privately held since founding, with ownership concentrated among the co-founders.
