Rootstrap

Rootstrap embeds senior engineers, designers, and product leaders into high-growth startups and modern enterprises that need to move fast without compromising quality. Founded in 2015 and operating from offices in Buenos Aires, Montevideo, and Medellín, the company has delivered over 700 product launches with a 200-person team distributed across Latin America. Their 4.8/5.0 rating on Clutch reflects a model built on flexibility: clients can hire a single specialized role or deploy an entire cross-functional squad, scaling up or down in days rather than months. The company's technical depth spans AI development, custom software, and mobile applications, with particular strength in LLMs, RAG pipelines, LangChain implementations, and cloud migrations across AWS, GCP, and Azure. They work primarily with midmarket and enterprise clients in financial services, healthcare, education, and media, structuring engagements as either staff augmentation or full-stack delivery depending on internal team capacity. Time and materials pricing billed in arrears means clients pay only for work they approve, with no long-term contracts or bench staffing overhead. MasterClass illustrates how Rootstrap adapts to client needs over time. The education platform started with three Rootstrap engineers, scaled to more than 50 embedded team members across their technology stack, then flexed back down as MasterClass built out its internal hiring. This elastic approach serves companies that need experienced product velocity during critical growth phases without the permanent overhead of a fully staffed engineering org.
