We master the tender process of turning ideas into winning qualitative and non-price criteria documents


Our core competition is writing winning offers for clients in infrastructure and energy.

We focus on tenders in which we can make a difference for our clients and hand in the winning bid. For us, it is important to work with clients that are just as passionate about winning the bid as we are. The culture match is just as important to us as the chance of winning. After all, good cooperation is the basis for the winning offer. Our eagerness of getting to the highest scoring bids means that we take the extra step and onboard expertise when required.

Bringing together complex substantive and technical knowledge from multiple internal and external specialists into readable and easy-to-follow plans? That is what we are for. Our seasoned bid professionals know what it takes to get to the winning bid, even when the pressure is mounting, and the interests are high. We build on a wealth of tender experience. Over the last 10 years our team of 40+ bid managers, coordinators and writers participated in over 500 public (B2G) and private (B2B) tenders and proposals, including leading projects in offshore wind and multidisciplinary infrastructure projects.  Our writing team combines expertise of common qualitative topics with bid writing expertise. We can therefore quickly get into the content with the client’s team and get into writing mode. Due to our wealth of tender experience, we are familiair with differentiating topics such as innovation, ecology, nature enhancement, system integration, safety-by-design, stakeholder management, digitalization and governance and compliance.

Our eagerness to win, combined with 10 years of experience with qualitative tender criteria, makes us a leading force in competitive tender management in energy and infrastructure.
