Vstorm vs Pento: overview
Vstorm
Vstorm has built AI systems since 2017 and now concentrates on LLM agents, with about 25 AI engineers on its bench and 40+ staff in total, mostly in Wrocław and remote across Poland. Its website names three situations it fixes, and one is an existing team that has stalled; there, Vstorm adds senior engineers who specialize in agent design, reliability and integration. Its longest package embeds a manager, a tech lead and engineers for three months or more. Deloitte and EY have both recognized the company, according to directory listings.
Pento
Pento is a Uruguayan AI and machine learning engineering firm founded in 2019, with roughly 25 to 50 people in Montevideo. Team augmentation is one of its two most common engagement types, and directory data puts its average team at about two and a half people with roughly three weeks to hire. DesignRush lists Mercado Libre and BASF among its clients. Montevideo is one to two hours ahead of U.S. Eastern time, so working days overlap almost completely.
