At Demo Day 2025, Constructor Start proudly showcased startups that recently completed the intensive accelerator program. There were 15 ideas, 15 stories, and 15 exceptional successes – but only one could take home the prize of $100,000. The honour went to Kudu – a startup revolutionising the world of medical implants by eliminating the need for battery replacement surgeries.
Although Kudu walked away with the top prize, the day proved to be a win for all competitors. Throughout the eight-week accelerator, they worked together to refine their business ideas and acquire new skills. During Demo Day, they all had the opportunity to present before industry leaders and prominent venture capitalists – a crucial step on their path to success.
“Constructor is building a global ecosystem to support 200+ early-stage tech startups every year with cutting-edge research in fields such as AI, robotics, neuroscience and advanced materials, as well as strong funding and support from 30+ aligned mentors and top industry experts from all over the world,” said Dr Serg Bell, Chairman of the Board of Constructor and Vice Chairman of the Board of Governors at Constructor University.
“Through Constructor Start, founders can receive up to $1 million in funding, including a $100,000 check after Demo Day. They also gain access to co-investments from trusted venture capitalists and business angels. With Constructor Knowledge, Capital, and Tech working together, we turn bold ideas into powerful companies that solve global challenges.”
The initiative reinforces Constructor Group’s commitment to innovation and success for the Bremen region and beyond.
An initiative of Constructor Capital and the Constructor Entrepreneurship & Innovation Centre at Constructor University, Demo Day, took place on June 10 in Bremen-Vegesack.
It provided a stage for young changemakers who are seeking to innovate and build solutions to global challenges – a crucial part of Constructor University’s DNA. Three thousand five hundred startups from the areas of B2B SaaS, Deeptech, and Edtech applied to be a part of Constructor Start’s 2025 Batch 1.
Over 150 participants took part in a self-paced online program through Constructor LMS, with just 32 selected to participate in the live online program.
They received one-on-one mentoring and an intensive eight-week curriculum featuring topics ranging from customer discovery to team management, legal considerations, and marketing.
The top 15, represented by participants from 11 countries, were allowed to compete in Demo Day and present their ideas on the big stage.
“I particularly liked the mentor matching. My mentor Evgeny Protasenko really helped me come up with a proper way to present a business plan,” said Yuval Shklarsh, CEO and CTO of Kudu, this year’s grand prize winner of USD 100k.
So, what sets Kudu apart? “We are putting patients first. And with our technology, we’re going to make battery replacement surgery a thing of the past.”
Instead, the company utilises ultrasound technology to extend the lifespan of medical implants, thereby reducing costs and limiting risks.
Overall, the participants represented a diverse range of sectors, including EdTech, HRTech, MedTech, and Sustainable Energy. The decision on who would receive the $100,000 in funding from Constructor Capital Venture Fund was based on the mission and vision of the startups, their product offerings, pricing models, scalability, and other relevant factors.
Demo Day and Constructor Start are integral to Constructor Group’s vision to drive advancements in science, technology, and education through its integrated ecosystem, which offers education, research, and business solutions.
Supported by Constructor Tech, startups have the opportunity to win the tools to flourish, including access to Constructor Tech’s advanced research platform, CT, and discount codes for Nexford’s ‘From Idea to Pitch’ course.
QazTwin, the winner of the audience voting process, also won an additional ten hours of mentoring from Dmitry Kurin, Director of the Entrepreneurship and Innovation Centre and CEO of the Constructor Start Accelerator. The next instalment of the program will start in Autumn 2025.
