Dynamita team reunites in Sigale

June 11, 2024

The Dynamita team reunited in Sigale in May. There was team building, delicious food, a party for Sandrine and some work done as well! We are looking forward to the second half of 2024 - there are some great conferences still to come, and the one you've all been waiting for - the release of Sumo 24 (we will let you know when that is, don't worry)!

It's time to say goodbye...

June 3, 2024

It's time to say goodbye... to Sandrine, who has retired. The team are really going to miss Sandrine, who has been with Dynamita officially since 2016, and unofficially - much longer! She's been Imre's right-hand gal, in work and life. Sandrine would say that she is going to miss you, our clients, the most, and she wishes you all the best for the future. So when you see her in Singapore for the Singapore International Water Week, please don't ask her for a quote (you can do that by emailing info@dynamita.com)!

Sumo can be rented and run from the Cloud

January 30, 2024


Dynamita is happy to introduce a new service to help clients who would typically use Sumo intermittently, while an annual subscription is beyond their budget. From now on, premiering in the market, it is possible to rent Sumo on a weekly basis, as a cloud-based software: Sumo for Rent.

This new service is not only flexible in terms of subscription length, but also offers platform-independence: you can run Sumo on any device that has a browser and Internet connection (even your cell phone). No need for software installation and license activation: just sign up, receive a password and you're ready to go! For further details about Sumo for Rent, please check out the Products page.

Team gathers in France, releasing Sumo 22.1

May 02, 2023

Dynamita folks reunited in SW France during the last week of April. It was great to meet each other again and greet our soon-to-be colleague, Sabrina (announcement to come later). Lots of fun, great food, some kayaking on the Lake of Arjuzanx, a lovely stroll in Bordeaux and crawling atop the great sand dune of Pilat made sure we don't get stranded behind our computers, still we made good progress work-wise as well.

As a result of that, Sumo 22.1 became available for download. For details about the changes in this release, please check out the What’s new in Sumo 22.1 document. This install will replace your existing 22.0 but can coexist with earlier versions (21, 19).

Sumo in Africa

February 04, 2023

After the first ever and best ever WRRmod conference in Africa in Cape Town, and recognizing the challenges African universities and startups face, Dynamita is pleased to announce the following support package:

To any university accredited and located in Africa - we are pleased to provide free unlimited perpetual licenses for the Sumo process simulation package including Digital Twin capabilities.

Any one- or two-person startup from Africa can claim a one year license of Sumo free of charge in their first year of operation.

This program will stand (at least) for the next ten years, until 2033.

Our hope is that this will result in cleaner environment and less bottled water in Africa. Free and Open source!
