About Spike

  • Founded in 2022 by Povilas Gudzius and Nikita Pajanok, Spike provides non-diagnostic, easy-to-implement Retrieval Augmented Generation (RAG) AI products through white-labeled SDKs. These products include personal trainer co-pilots for fitness progress, dietitian co-pilots for nutrient assessment, nurse co-pilots for post-treatment follow-up, and physician co-pilots for anomaly detection from EHR and lab test data.
  • Spike serves clients in digital health, professional fitness, nutrition, healthcare, and insurance sectors. The list of users includes the global insurance company Seguros SURA, fitness apps Longevo and FITTR, sleep innovation company EMMA, women’s wellness app Moody Month, and vagus nerve stimulator Pulsetto.

In December 2022, Spike received $700,000 in a pre-seed round led by the Ukrainian-Belarusian VC fund Geek Ventures.

Advancements in retrieval-augmented generation AI mean that LLMs are no longer taking a ‘best guess,’ but are now able to seek out specialized 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,

Povilas Gudzius, Spike CEO and co-founder, says.
