Tensorway vs Rootstrap: overview

Tensorway

Tensorway is the AI-focused unit of an established Alicante, Spain software development company with roughly 25 years in the market, spun out specifically to build agentic systems at a team size (50–249 people) closer to an agency than a global systems integrator. Its six-phase delivery methodology takes a client from assessment to a working agentic MVP in roughly a month, with compliance embedded rather than bolted on, and a discovery-first exploratory track lets smaller buyers de-risk before committing to a full engagement. That agency-scale headcount, paired with a decades-old parent company, is an unusual combination on this list.

Rootstrap

Rootstrap is a software development agency founded in 2011 and headquartered in West Hollywood, California, with additional offices in New York, Montevideo, and Buenos Aires, and roughly 190–200 employees. It is known specifically for integrating multi-agent workflows into digital products rather than delivering standalone backend automation, applying existing product-engineering discipline to agentic feature work. An Inc. 5000 honoree, its Latin American delivery centers give it a cost-effective bench for agency-scale engagements.

Tensorway
+ Discovery-first option lets smaller buyers de-risk before committing to a full engagement

- Minimum engagement and project-count figures are sourced from the company's own site and independently unverifiable
Rootstrap
+ Specific track record integrating multi-agent workflows directly into shipped digital products
+ Multi-region footprint (US, Uruguay, Argentina) balances US account management with cost-effective delivery
+ Inc. 5000 honoree with over a decade of operating history since 2011
+ Product-engineering discipline means agentic features arrive with real UX consideration
- Minimum engagement figures are not published, requiring direct sales contact for early budgeting
- Broader product-agency origins mean agentic-specific depth should be confirmed against narrower specialists
- Reported headcount varies by source (roughly 191 to 500), worth confirming directly
