Vilnius-based Spike, a B2B data technology and AI startup, has successfully closed an oversubscribed €3.2 million seed round to fuel growth and product expansion. The round was co-led by Practica Capital and TheVentureCity, with participation from investors in Silicon Valley, New York, and Berlin, including CEAS Investments, Plug & Play Ventures, Geek Ventures, and Axel Springer Porsche (APX).

Spike offers healthcare and digital health businesses AI solutions that are safe, efficient, and compliant. These solutions enable organisations to offer hyper-personalized and preventative health products through health data, LLMs, computer vision, and ML techniques. However, integrating these technologies often faces regulatory compliance, LLM hallucinations, competition for AI talent, lengthy development timelines, and high costs.

Spike addresses these challenges with its white-labelled SDKs, providing non-diagnostic RAG AI products for health professionals and end-users. Examples include personal trainer co-pilots for fitness data, dietitian co-pilots for nutrient assessments, nurse co-pilots for post-treatment follow-up, and physician co-pilots for early anomaly detection from EHR and lab test data.

The startup's competitive edge is its health data API aggregator platform, which feeds high-quality biomarkers from 300 sources. This platform secured Spike a spot in NVIDIA’s Inception Program for GenAI startups in Silicon Valley. Spike’s clientele includes global insurance leader Seguros SURA, fitness apps Longevo and FITTR, sleep innovation company EMMA, women’s wellness app Moody Month, and vagus nerve stimulator Pulsetto.

Povilas Gudzius, Spike CEO and Co-founder, stated, “Advancements in retrieval-augmented generation AI mean that LLMs are no longer taking a ‘best guess,’ but are now able to seek out specialised context producing outputs that are much more accurate and considerably less prone to hallucinations. By incorporating this technology on top of Spike’s high-quality health data API, we’re enabling our clients to easily leverage these tools and improve the health of millions of end users.”

Donatas Keras, Partner at Practica Capital, said, “We were impressed by the Spike team’s technical expertise and go-to-market skills. Given their rapid traction and widespread adoption of AI products with formidable competitive moats, leading this round was a natural fit for us. As the influx of sensor data changes some parts of the health industry, Spike is well-positioned for significant growth, and we are excited to partner with such a forward-thinking team.”

Álvaro Sanz, Partner at TheVentureCity, added, “The fact that Spike was able to close an oversubscribed round and accumulate significant investor interest, particularly in this down market, is a validation of Spike’s potential.”

Founded 18 months ago by Povilas Gudzius, formerly of Bloomberg's Quant data and AI team, and Cambridge-educated Chief Data Officer Nikita Pajanok, Spike's team includes Auguste Kakneviciute, former Lead of IoT Sales at Ubuntu; Monika Da Silva Xavier, ex-Google; Anton Autushka, ex-head of Engineering at Wannaby (sold to Farfetch); and 17 other tech specialists.
