## Curator assessment
Reviewed 2026-09-23 by Gabor Kiss against published evidence.

The two most detailed AI studies on Vention's site describe its own internal tools: a legal-document RAG platform the study reports as live, answering at about 88% accuracy in three to 10 seconds, and a marketing assistant on Claude Haiku and Sonnet through AWS Bedrock that was still moving from proof of concept toward an MVP.

Client-side AI is thinner than the positioning: in the EliseAI study the AI is one line—automated replies added during four years of database, security and QA work—and in the Kafene study it is Cursor and CodeRabbit inside the development process, credited with 15–20% higher engineering efficiency.

The Comet and Vexcel Imaging engagements are real engineering next to AI—SDK and dashboard work on an ML platform, and a serverless image-processing pipeline—rather than a model trained for a client.

The weaker fit is buyers commissioning a production ML or LLM system from scratch, who should ask for a client reference where Vention built the model and still runs it.

### Key strengths
- The internal legal RAG study publishes its design—interpreter agents, query expansion, multi-answer synthesis—plus an 11-week MVP, a three-person team and about 88% response accuracy
- Long engagements with named product companies: four years at EliseAI, 3.5 at Vexcel Imaging, three at Comet and 3+ at Kafene, where the co-founder is quoted by name
- The Vexcel study documents a serverless AWS pipeline (Step Functions, Lambda, GDAL, Rasterio) that processes up to 1,000 aerial images in 15–20 minutes instead of weeks

### Good to know
- EliseAI results differ by page—125% more conversions on the case study, 65% on the AI solutions page—so ask which figure is current and how much of it Vention's work drove
- The AI page claims 150+ completed AI projects, but published client studies show little model-building—ask for two client references where Vention built and operates the model
- The London office is described as a local point of contact, with delivery from centers across Europe and Asia—ask where your team will sit and who leads it day to day
