Nex2us

What Nex2us does

Nex2us B.V. is a privately held Dutch building regulations consultancy headquartered in Etten-Leur, Netherlands, founded in 2012 and operating with a team of 8-9 certified advisors. The firm provides professional advisory services across the Dutch construction value chain — fire safety, building physics, acoustics, energy performance, building regulations compliance (Bbl/Bouwwetten), and Wkb quality assurance — serving project developers, architects, contractors, housing corporations, and government bodies. Core technical capabilities include CFD-based fire safety engineering per NEN 6060/6079, BENG calculations per NTA 8800, thermal bridge and daylight analysis, GPR Gebouw and MPG environmental assessments, and certified energy label issuance (EP-W/EP-U, BRL 9500).

The company's product portfolio is organized as a single integrated advisory practice rather than a software platform. Domain-specific service lines (Brandveiligheid, Bouwregelgeving, Akoestiek, Bouwfysica, Energie en duurzaamheid, Energielabel, Kwaliteitsborging, Kennisoverdracht) cover the construction lifecycle from preliminary design through operational phase. Two distinctive commercial formats stand out: the Advies Strippenkaart (DAS), a prepaid punch card selling advisory time in 10/20/40-strip packages (each strip = 15 minutes) valid for one year at EUR 400-1,400, and in-company Bbl training programs (Update Training and a two-session Verdipingstraining) introduced around the January 1, 2024 transition from Bouwbesluit 2012 to the Besluit bouwwerken leefomgeving (Bbl).

Nex2us generates revenue primarily through fee-for-service professional advisory engagements, supplemented by subscription-style prepaid advisory (Strippenkaart), training programs delivered in custom in-company formats, and official energy label issuance and registration. The go-to-market is sales-led and direct, relying on the firm's decade-long relationships with major Dutch developers and contractors (Heijmans, BAM Utiliteitsbouw, BPD, ASR, Amvest, Stadlander, De Alliantie) and its content-marketing presence via a Dutch-language website. Projects span residential, commercial, mixed-use, healthcare, education, and public-sector builds across the Randstad and broader Netherlands, with 70+ completed projects and 90+ named client organizations referenced. The company is bootstrapped and independently owned, with no external investors, parent company, or M&A activity disclosed.
