About Diamax

Diamax helps non-profits and the companies that serve them, transform their businesses for maximum impact and long-term sustainability. 

We are a technology consultancy based in Washington DC since 1998, specializing in custom digital solutions that large consultancies can't implement efficiently, yet too important to proceed without an established, long-term partner.

Diamax also engineers smart, simple software products that allow us to rapidly deliver high quality, standardardized solutions to common challenges faced by our clients.

Our customers include international organizations such as the World Bank, premier institutions like the National Academy of Engineering, and influential industry trade associations such as the Interstate Natural Gas Association of America.

What We Offer

Diamax is a full-service consultancy, offering digital strategy, solution design, software engineering, and maintenance services to clients in the United States, Canada, and Europe, where we also have an office.  Our team of professionals build long-term relationships with our cusomers to ensure our technology solutions remain strategically aligned in support of executive priorities for many years.

We offer 2 decades of experience designing and engineering innovative, user friendly solutions using Microsoft technologies, such as Azure, Microsoft SQL Server, Microsoft Data Platform, Dynamics 365, and Microsoft-based technologies like Milieu.

We also provide enterprise integration services and application upgrades, even when the technologies involved are decades old and poorly supported (for example, Lotus Notes databases, Classic ASP, etc.).

Finally, we offer Milieu directories, knowledge bases, and communities, implemented and ready for engagement in as little as 2 weeks.

Our Mission

To generate enduring, positive impact through digital solutions that transfer knowledge, strengthen community, and unleash human capital.

Why Did We Create A Software Product?

You've never seen a directory, a knowledge base, or a community like one powered by Milieu, because we put them all together. Experience taught us these three components fall short of expectations when they are implemented separately.  In the non-digital world, all these elements exist together in one place as interwoven parts of a community that offers context for engagement.  For years, we developed custom solutions that combined these elements but that's too slow and expensive. Our combined approach to directories, knowledge bases, and community has been so successful for our customers that it made sense to standardize the technology as a product.

There is no obligation to purchase Milieu and many of our solutions are built without it.

Who We Are

We are an experienced team of strategists, designers, and engineers working for customers around the world.

Innovation starts with mindset, and that is enabled by a bold culture. Our culture is based on the following values.

  • Partner for Success - invest in long-term client relationships 
  • Stay Aligned - constantly listen and adjust
  • Respect Everyone - value all perspectives, especially the old ones

  • Think Big - transformation is always possible
  • Get Results - the job isn't done until the targeted outcome is achieved

We are based in Vienna Virginia, only minutes from Washington DC. Our European office was established in 2007 and is located in the historic center of Bucharest Romania.

Businesses We Know Best

Over the past 21 years Diamax has worked with a broad range of clients, and our adaptability is one of our strengths, but there are a few areas where we really shine because of the depth of our experience.

Directory Publishing - We are leading experts on the transformation of directories into vibrant content marketing communities and customer engagement marketplaces.  We offer unparralleled solutions and growth strategies for B2B buyer's guides, academic program directories, member directors, local chamber of commerce directories and more. 

Distributed Program Management - We have deep experience developing and maintaining program management systems for distributed teams that represent multiple stakeholders, operating around the world, to complete projects, develop standards, produce reports and manage outcomes. It's not easy to orchestrate collaboration at scale when participants don't work for the same employer, but we have a track-record of success.

Associations - We have been achieiving digital transformation for trade associations and professional societies for 2 decades.  Regardless of what makes your association and its stakeholders different, we know how to grow membership, retain existing members, increase non-dues revenue, and improve efficiency. 

Engineering - We have deep experience working with organizations and corporations where engineers and scientists,
engineering, engineering policy, STEM education, and engineering communications are the focus or a cornerstone of success. We believe that engineering will enable solutions to the world's most daunting challenges.

STEM Education - We have been engaged in world-class programs related to STEM education from pre-K through graduate school for 20 years. Some of our biggest impacts have been in this practice area and it will remain core to our work programme for many years to come.

Energy - Over the past 10 years Diamax has focused a significant proportion of our consulting practice on oil and gas pipeline associations and their members. We are engaged in initiatives to improve research efficiency and the transfer of knowledge in areas related to construction, operations, research, security, and environment. 

Public Policy - Our years serving Washington DC’s unique mix of government, business, academe, and non-profit interests has equipped us with a solid understanding of policy. Digital transformation can help bring stakeholders together to achieve consensus on policy recommendations and create coalitions to drive implementation.  We believe in evidence based policy, the power of open data, and the imperative of information access to enable viable, democratic outcomes.

International Development - We have over 20 years of experience working within leading institutions working to end poverty and enable sustainable development. Our solutions have helped executive offices, operational departments, and field level missions alike, to innovate, become more agile, and amplify impact in their relentless pursuit of a better world for billions.  


Diamax is a certfied small business with an excellent contracting history.  We work directly for most of our customers, but we are proud to team up and subcontract where our impact can be amplified.
