New York, Wednesday, October 4, 2023

LANGaware, a US and Greece based company revolutionizing cognitive and mental health diagnostics through AI-driven technology, has successfully raised $2 million in funding. The Seed round is led by Eleven Ventures, a leading early-stage venture capital firm in Southeast Europe. Strategic investors from the healthcare industry, alongside existing investor Metavallon VC, are also participating in the round.

Founded by Dr. Vassiliki Rentoumi, a renowned researcher in Natural Language Processing and Computational Linguistics, LANGaware employs Artificial Intelligence to predict and monitor cognitive and mental health conditions (such as Mild Cognitive Decline, Alzheimer’s Disease, and Depression). By analyzing language, voice, and speech through digital biomarkers, their patented technology offers a new lens for healthcare. Developed over several years of research, the platform has been rigorously tested and proven effective in both clinical and virtual care settings in the US and Greece. LANGaware aids health systems, providers, and pharma firms by facilitating early detection and tailored support. It reduces healthcare costs and improves patient outcomes by ensuring accurate diagnoses and minimizing unnecessary treatments.

Eleven Ventures, known for their expertise in nurturing and scaling innovative startups, is a strategic partner for LANGaware in this funding round. The Sofia-based venture capital firm has an impressive track of identifying and supporting companies at the forefront of healthtech breakthroughs, ensuring that transformative solutions reach those who need them most. The funding will be used to enhance LANGaware’s technology and product teams, boosting their AI capabilities developing comprehensive data-driven solutions, and to expand the company’s business development team and presence across virtual care platforms and health systems in the United States. 

“We are thrilled to secure $2 million in funding, with support from Eleven Ventures, Metavallon VC, Cleverage VC, and strategic angels in the healthtech sector,” said Vassiliki Rentoumi, Founder and CEO of LANGaware. “This investment propels us forward, unlocking the potential to revolutionize healthcare systems by unleashing the full power of AI. By harnessing the power of technology, we aim to alleviate the strain on overburdened healthcare systems, while driving down costs and fostering a future where accessible, high-quality healthcare is a fundamental right for all.”

Valeri Petrov, Partner at Eleven Ventures, expressed his enthusiasm for LANGaware’s potential, “Problem” is a light word to describe the domino effect of late-stage diagnostics in neurodegenerative disorders. For example, Dementia Medicare beneficiaries receive nearly 3x > payments compared to other receivers but early diagnostics can save up to $14K annually for payers, a 1/3rd of the total cost.  Through its speech-based flagging system for early detection, LANGaware is an example of how even the most pressing issues in healthcare can be addressed through the power of science and technology.  We are excited to support Langaware in their mission to impact millions of lives and contribute to a more efficient and timely treatment.”

Through their AI-powered solutions, LANGaware is striving to create a world where individuals receive timely interventions, leading to improved outcomes and a higher quality of life.
