About this list
B2B automation lives or dies on the systems it plugs into, and much of the documented work here is integration. Flobotics moves data between electronic health record systems for DocPlanner at more than 10,000 processes a month, with 98% handled without a person, and states which tool it chose and why. 10Clouds embedded machine-learning engineers inside Trust Stamp's identity work for more than five years, under the client's own data constraints. TUATARA's Actionbot sits against CRM and other data sources across banking and telecom channels. Atomic Actions works the lightest version of the same idea, with OpenAI calls inside Make.com workflows that turn documents into invoices and spreadsheet rows.
The page also reaches past integration. Brights shipped a multi-agent retrieval consultant to the Kadroland and 7eminar HR and accounting platforms after a proof of concept graded by the client's own experts on 250 questions. Mobile Reality's deepest AI engineering is on its own products, including an open-source framework for LLM-generated forms, and QED Software's clearest client evidence is a named CTO crediting its models with 25% more efficient alert analysis.
For a B2B buyer the useful question is not which model was used but what happens at the boundaries: which system owns the record, what the automation does when an upstream API changes, and who is paged when it stops. Ask each candidate to describe a failure they handled in production—firms with real integration histories answer with specifics, and the ones selling a demonstration change the subject.

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.
