Tensorway vs Brainpool AI: 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).
Brainpool AI
Brainpool AI was set up in London in 2017 (its incorporation date is February 2016) as a network of AI and ML experts, and it now counts more than 500 vetted PhD and MSc specialists across 23 countries. Co-founder Kasia Borowska built the business on matching that network to client problems. Over time it has shifted toward its own platform, Cortex, on which it builds LLM agents, fine-tuned models and MLOps setups. In 2019 it raised just over £200,000 through equity crowdfunding.

Tensorway vs Brainpool AI: 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 |
| Brainpool AI | |
|---|---|
| + | Deep academic bench for unusual research questions |
| + | Experts available in many countries |
| + | Can switch to building on its own platform if you need delivery |
| - | The company is moving from expert placement toward its own product |
| - | Sources disagree on the founding year (2016 or 2017) |
| - | Small core team behind a large external network |
