Vision
To make documented airtightness a natural part of every construction process, thereby ensuring that the buildings of the future live up to their full potential in terms of quality, energy efficiency, and durability.
Mission
We develop technology for ongoing quality assurance and documentation of vapour barriers. By identifying leaks during construction and verifying the final result through final testing, we help construction professionals build it right the first time, reduce energy loss, and eliminate unnecessary costs associated with corrective measures.
LeakHunter began as an idea back in 2008, when Lars noticed that a large number of projects failed the final pressure test. This included cases where the quality and tightness of the installed vapour barrier/building envelope were unsatisfactory. For example, the entire first floor might have to be rebuilt, which could quickly cost over 500,000 kr. in additional work.
It became clear that if there were a tool on the construction site that could identify where the leaks were and ensure that the overall airtightness of the building was satisfactory, it would save a lot of frustration and money. And that is exactly what LeakHunter can do.
Technical Advisor / Partner – Bricklayer & Civil Engineer.
Lars is the ideas man behind LeakHunter. Lars has many years of experience with pressure testing and blower door tests and has measured practically every building challenge related to airtightness.
Since 2004, Lars has been working with Roskilde Technical School on
efteruddannelseskurser inden for opsætning af dampspærrer som i dag er en integreret del af tømreruddannelsen. Lars’ nysgerrighed og store viden om opsætning af dampspærrer og trykprøvninger har lagt fundamentet for udviklingen af LeakHunter.
CTO / Partner – Mechanical Engineer.
Anders is a passionate mechanical engineer with an eye for detail. Anders is the CTO and oversees the technical development of LeakHunter.
”Udviklingen af LeakHunter-enheden har været en vild proces. Første prototype lignede en rumraket og vejede over 40kg. Nu står vi endelig med LeakHunter, der er resultatet af et flerårigt udviklingsprojekt udviklet i samarbejde med DTU og en lang række underleverandører. At det er lykkedes os at skabe et kompakt og intuitivt anvendeligt produkt, der kan hjælpe håndværkeren til at kvalitetssikre sit arbejde og tilmed skubbe byggebranchen i en mere bæredygtig retning, er for mig super fedt, god jagt.”
CEO / Partner – Management & Business Development.
In 2026, Jesper joined LeakHunter as CEO and co-owner. He has run his own business for over 20 years and brings to LeakHunter many years of experience as a business consultant and board chairman at several Danish companies. Throughout his career, he has gained extensive experience in business development and strategy in both growth and transformation initiatives.
Together with LeakHunter’s highly skilled development and technical team—Anders Rostén and Lars Due—Jesper helps ensure that LeakHunter can deliver even better solutions to the industry.
Administration.
Rikke is an important part of LeakHunter's administrative team and is responsible for bookkeeping and invoicing at LeakHunter, among other things. In addition, Rikke is also a member of the marketing team.
Commercial Operations – Sales & Marketing.
Alexander has a broad background in sales and marketing and holds a wide-ranging role at LeakHunter. Among other things, Alexander is responsible for the website, social media, warehouse, logistics, production and sales of LeakHunter, in both the Danish and export markets. Alexander also carries out pressure tests and smoke tests.
Byggeriet står for 38,4 % af al affald i EU (Eurostat, 2022). Hver gang en bygning dumper tæthedsprøven, og dampspærren skal åbnes og laves om, går der materialer, tid og penge til spilde.
Det vil vi gerne lave om på. Vores vision er at gøre dokumenteret lufttæthed til en naturlig del af enhver byggeproces. Med LeakHunter kan du kontrollere tætheden løbende i Cruise mode og finde utæthederne, mens konstruktionen stadig er åben – så fejlene bliver rettet med det samme i stedet for at blive opdaget ved sluttesten.
Bæredygtigt byggeri handler ikke kun om materialerne. Biogene materialer og et lavt CO₂-aftryk i byggefasen er vigtige, men utætheder giver et varmetab, der koster energi i hele bygningens levetid. En forbedring af tætheden fra 1,0 til 0,2 l/s pr. m² sparer ca. 4–5 kWh/m² om året på opvarmningen – og lufttæthed koster stort set ingenting i materialer, kun omhu og kontrol.
