Tensorway vs Addepto: full comparison for 2026

Quick verdict

Tensorway (4.8/5) edges ahead of Addepto (4.2/5) overall. Tensorway is the better choice for teams whose AI pilot works but can't ship. Addepto is the stronger option for mid-size firms wanting tested LLM apps cheaply. The right choice depends on how far your pilot has got, your budget, and who will run the system after launch.

Tensorway vs Addepto: overview

Tensorway

Tensorway, founded in 2019 and based in Alicante, Spain, is an AI engineering firm of more than 50 people whose practice has roots in over two decades of running production systems for clients. Its production work starts with a gateway in front of the models. That gateway logs every request, enforces rate limits, tracks cost per feature, sends routine traffic to cheaper models, and fails over to a backup model during a provider outage. Prompt and model changes are regression-tested before release. New versions then go out through a canary rollout with fallbacks, so a bad change reaches only a small share of users. For a US trading platform with more than 100,000 investors, it reports market-data processing 40% faster and institutional operating costs 35% lower after an agentic AI build (per company website; independently unverifiable). It publishes no rates.

Addepto

Addepto was founded in Warsaw in 2017 and was acquired in December 2025 by KMS Technology, an Atlanta engineering company backed by Sunstone Partners. It built ContextCheck, an open-source framework for testing language models and chatbots, which says something about how it approaches quality before release. Its chief executive says 97% of staff are AI engineers (per company website; independently unverifiable). Clutch lists $50–$99 an hour and a $10,000+ minimum project.

Tensorway vs Addepto: pros and cons

Tensorway
+ Swapping one model for another doesn't mean rewriting the application, because every call goes through its gateway
+ Prompt and model changes are tested against benchmarks before release, which catches quality drops early
+ Canary rollouts with fallbacks limit how many users see a bad change
+ Cost per feature is tracked from day one, and routine requests go to cheaper models
+ Watches hallucinations, drift, latency, and API spend after launch, with an optional managed service
- A team of 50+ can't offer the round-the-clock global coverage of the large integrators
- No public price list, so budgets are only known after the audit
- No certifications or named cloud-partner tier appear on its pages
Addepto
+ ContextCheck shows real investment in testing language models
+ A $10,000+ Clutch minimum makes a small first project possible
+ Databricks experience for data-heavy builds
+ Team is almost all engineers
- Acquired by KMS Technology in December 2025, so teams and priorities may change
- No managed-run service listed
- Less depth on staged rollouts than the leaders
