Since its founding in 2006 Intespring has been focussing on gravity compensation.
By using smart mechanisms and efficient energy storage like i.e. springs it is possible to passively exert any preferred force characteristic.


This knowledge has resulted in several products and spin-off companies. The BalanceBox, was one of InteSprings first products to hit the market and its patented technology is still owned by a joint venture of InteSpring Holding and her partner Thomas Regout.

In the last four years, InteSpring has been focussing more and more on gravity compensation and force actuation in humans resulting in the development and production of different types of exoskeletons:


The Laevo exoskeleton. A small lightweight passive exoskeleton that can prevent back injuries. This project resulted in a new joint venture (Laevo B.V.) with the biggest Health Insurance company of the Netherlands (Achmea).


The Exobuddy. A semi-passive exoskeleton that supports backpacks of military personnel. It’s becoming the smallest and most lightweight exoskeleton in the world that supports high payloads (up to 60 kg).


Medical orthoses for rehabilitation purposes. Exerting and adjusting a predefined force-characteristic in lightweight orthoses is especially interesting for rehabilitation purposes. The compact and efficient energy storage mechanisms of InteSpring are used in several design concepts and rehabilitation studies with DUT, LUMC and the University of the Hague.

How we do it

InteSpring offers innovative solutions.

These projects are often hard to predict.


How we control risk, costs and leadtime?

By dividing projects in the following phases:


Phase 0:

Technical and economic feasibility.

Within 40 hours InteSpring will research technical and economic feasibility, answering the following questions:

  1. Are there technical solutions that can solve this problem?
  2. Is it likely that these solutions are also cost-effective?
  3. Is InteSpring the best partner in this project?

If the substantiated answer on all three questions is yes, than InteSpring will offer a quotation for the next phase.


Phase 1:

Technology demonstrator.

InteSpring will build a technology demonstrator, that proofs the working principle and functionality of the solution. It will be possible to walk around, touch and experience the solution. This provides insight into the final product. The technology demonstrator is not yet optimized for volume, weight, cost, etc. Are you satisfied? Lets continue with the next phase.


Phase 2:


The prototype will be optimized for volume, weight and other criteria, while preserving functionality of the Technology Demonstrator. It provides an accurate view of what is to be expected of the final prototype. The prototype is ideal to demonstrate to your partners and clients.

Prototypes will also be used for the first durability tests and risk assessments to expose vulnerable parts.


Phase 3:


The final product will be optimized for quality, production, costs and usability.

Frank has also over seven years of work experience as an Industrial Design Engineer. He optimized and launched several Medical Products for different companies. Since 2016 he is a part of the InteSpring team, specializing in project management as well as improving the balancing- and force calculation software of InteSpring. Frank is a typical all-round engineer who is capable to quickly understand the true challenge of the customer and to come up with innovative ideas to tackle that challenge.

Trebsijg van de Wijdeven (MSc)

Senior Mechatronics Engineer

Read more

A highly skilled mechatronic engineer with a master degree in hydrodynamics. If it uses electricity, than Trebsijg can hack it. As key designer in the Exobuddy project he was responsible for the working principle as well as trouble shooting in case of any malfunction. The capacity of Trebsijg to build small test setups in a short time frame accelerates every project.

Rogier Barents (MSc)

CEO and co-founder of InteSpring

Read more

Rogier graduated at the Delft University of Technology with a specialization in Bio Mechanical Engineering. Starting as the lead engineer within InteSpring in 2006, he became the CEO in 2010. Rogier is capable to get things done by enabling the team to work within their best capacities. Setting up and managing innovative projects is Rogiers talent.

Boudewijn Wisse (MSc)

Co-founder of InteSpring and visionair

Read more

Boudewijn can predict the demand for certain products and therefore setting a clear goal for any company. The BalanceBox, the Laevo Exoskeleton and the Exobuddy all started out as an idea from Boudewijn. Currently Boudewijn is the CEO of the sister company: Laevo

Hanneke Loefs-Mos (BA, RC)

CFO of InteSpring

Read more

Her first-year diploma (propedeuse) in Industrial Design, shows Hannekes affinity with design and engineering. However, her true expertise lies within the field of finance of small to medium sized companies. Within the world of tax regulations, grants and share premiums it is Hanneke who knows how to find her way, even where a tax office doesn’t.

Amber Massaar

Office Manager

Read more

Office Manager with a degree in facility- and human resource management. Amber is part of InteSpring since 2015 and she is the oil in the engine called InteSpring. Without Amber all processes and communication would come to a standstill. Amber is on top of all activities in InteSpring and is capable to kindly remind team members on hard deadlines.


A lot of products are heavy to operate. By gravity compensation or by exerting force through compliant mechanisms, it is possible to make products function better, faster, lighter and safer.

Besides the development of Exoskeletons, InteSpring also develops smart balancing devices for other purposes.
