About this list
Business-to-business AI in Madrid sells into procurement, operations and finance departments, and the evidence on this page splits by the size of the buyer.
Plain Concepts works at group scale on Azure, with AENOR's search over 50,000 published certifications and a governed generative-AI platform for Nestlé employees. Sngular staffs multi-year engineering programs and publishes Vítaly, where seventeen processes moved onto three RPA robots and customer-service response times fell 60 percent. Unlock Management works the other end of the market: an order-taking assistant for Ajusa deployed inside the client's own Azure subnet against SAP and catalog APIs, with Logic Apps orchestration, Application Insights tracing, role-based authorization, explicit confirmation before any order is written and human escalation on ambiguity. Cloud District sits between them, adding AI into systems it has run for years—the Compass Group purchasing portal carried 745,000 orders and 710,000 goods receipts in 2025.
B2B automation lives or dies at the boundary with a system of record, so read the architecture sections rather than the outcome bullets. Ask what the system writes back, what it refuses to do without a human, and how a bad extraction is caught before it reaches an invoice or an order. Note too that several figures on this page are self-reported single numbers with no baseline method published—useful as direction, weak as proof.

Expert Insight
Why B2B fit matters
B2B AI lives inside operational systems, so integration experience is delivery experience—an agency that has shipped into an ERP or a ticketing queue has already fought the battles your project will fight.
Operational outcomes are checkable in a way marketing outcomes are not: handle time, error rate and hours removed either moved or they did not, and the strongest agencies here publish those numbers.
The internal business case matters—an agency whose case studies quantify results gives your sponsor the numbers to defend the budget with.

Published rates across this page's agencies run €20–130 per hour (median ~€65). Project totals depend on scope — the rate index at /rates breaks the computed bands down by region, country and team size.
