n8n saves Huel over £100,000 in SaaS costs and 1,000+ hours of manual work through enterprise-wide AI automation

The problem

Despite early adoption of tools like ChatGPT, Huel found that standalone AI assistants left value siloed within each individual tool with no way to connect AI to the systems and processes employees relied on daily. Many existing SaaS tools were also expensive, specialized, and too rigid to adapt as business needs evolved.

First attempt

Standalone AI tools like ChatGPT kept value trapped within individual tool boundaries, preventing AI from integrating with operational systems. Existing SaaS tools were too specialized and rigid to consolidate or adapt across departments.
