A free audit of your acquisition, delivered within 48 h.
Everything starts from public, verifiable data. Strengths are written from each agency’s website; no rating or figure is made up.
Score = (reviews ÷ (reviews + 20)) × rating + (20 ÷ (reviews + 20)) × 4.84. 4.84 is the average rating of the verified pool. An agency rated 5.0 on 12 reviews therefore does not automatically beat one rated 4.9 on 90 reviews.
Ask to see an agent that has been running for a client for several months: what it handles, its error rate, and who monitors it.
Test sets, answer evaluation, model call traces: without measurement, there is no way to know whether an update improves or degrades the agent.
Which model, hosted where, with what data retention? A self-hosted or EU-hosted open-source model may be required for sensitive files.
Tokens consumed, hosting, vector database, maintenance: get the monthly cost estimated at your real request volume.
Source code, prompts, training data and API accounts should belong to you, so you can switch provider or model.
Uclic designs custom AI agents (Claude, GPT or an open-source model hosted on your side for sensitive data) plugged into B2B acquisition and operations: prospecting, content, CRM. If your project is mainly a full business application, an e-commerce platform or an AI transformation for a large group, one of the studios or firms above will be a better fit.
Our Google listing shows 5.0/5 from 7 reviews (checked on 29 October 2026), below the 10-review threshold applied to the other agencies.

In 2026, 78% of B2B companies integrate AI into at least one business function. Median ROI 2.4x, AI agents, concrete B2B use cases: the complete guide to deploying AI in business without repeating the mistakes of the 79% who still fail.
Lire l'articleIt is a program that relies on a language model (GPT, Claude, Mistral…) to carry out a business task end to end: read a request, search your documents or CRM, decide on the next step, draft, then act in your tools. “Custom” means it is designed for your processes and data, not bought off the shelf.
A chatbot answers questions; an automation chains fixed steps. An agent combines both: it understands a situation, chooses the actions to take and executes them across several tools, with a human approving sensitive cases. It is more powerful, but requires testing and ongoing monitoring.
We start from our database of 4,648 agency listings taken from Google Maps. We remove closed, rejected listings and those with no website, no Google listing or fewer than 10 reviews, we merge duplicates (an agency present in several cities counts once), then we check on each agency’s website that AI agents is the service it actually leads with. The remaining agencies are ranked by their Google rating weighted by review count (Bayesian rating). Ratings and reviews were checked on 29 October 2026.
No. No agency was contacted or paid, and none can buy its place. An agency that closes its Google listing or drops below the review threshold leaves the list automatically.
Uclic publishes this comparison and lists itself first, and says so clearly. Its position is not computed with the formula: the agencies that follow are ranked solely by their Google rating weighted by review count.
