Tensorway vs Pento: overview

Tensorway

Tensorway was set up in Alicante, Spain in 2019 to do one thing: AI engineering. Its delivery practice draws on more than two decades of software engineering. Its staff-augmentation service supplies ML engineers, AI agent developers, data engineers and other specialists who work inside the client's own Slack, Jira and repositories. Most engagements start as a squad of two to five people and change shape as the work moves from research to production, with a part-time fractional expert as an option when a full seat is too much. The company's case studies include a multi-billion-euro Swedish private equity fund, where an AI-agent system reportedly cut deal-sourcing time by 80% and screens more than 5,000 opportunities in hours (per company website; independently unverifiable).

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.

Tensorway vs Pento: pros and cons

Tensorway
+ Candidates pass a code review, a practical task in their specialty and a communication check, all run by senior AI engineers
+ A two-week trial sprint lets you judge real output before the monthly commitment starts
+ Fractional experts cover narrow needs, such as a few days a week of fine-tuning or GPU cost work
+ Code, documentation and trained models stay in your repositories, and handover to in-house staff is planned from the start
+ Shortlist in days and first engineer in one to two weeks (per company website; independently unverifiable)
- No published rates, so budgeting needs a call
- The bench is far smaller than Quantiphi's, so a request for ten engineers at once would stretch it
- Time-zone overlap is agreed per engagement; there is no fixed nearshore promise
- Staffs AI and ML roles only, so general web or mobile developers have to come from elsewhere
Pento
+ Same working day as U.S. East Coast teams
+ Published rate band, unusual for this list
+ Reviewers praise value for cost and responsiveness
- Very small team, so only a few engineers can join at once
- Few public reviews to judge consistency
- One reviewer wanted clearer project timelines
