Complex multi-step automation workflows that connect your tools, move your data and trigger the right actions at the right time — without manual intervention. We design, build and deploy n8n workflows across self-hosted and cloud instances, from simple two-step automations to enterprise-grade operational pipelines.
n8n is the most powerful self-hosted automation platform available — and our preferred tool for clients who want full control over their data and workflow logic. Unlike SaaS-based automation tools with restrictive task tiers and per-step pricing, n8n workflow automation offers unlimited execution scale, native AI agent integration, advanced branching algorithms, and zero data exposure to third-party vendors when self-hosted on your own infrastructure.
Our custom workflows connect complex CRM systems, ERPs, webhooks, databases, and custom AI reasoning engines into resilient pipelines built to handle real-world edge cases — not just the happy path. Whether you need self-hosted Docker deployments, robust error-intercept logic, or bi-directional API synchronizations, we deliver complete workflow architectures with 100% full workflow file and code ownership—no recurring platform markups, no proprietary vendor lock-in.
From intricate multi-step operational pipelines and CRM/ERP integrations to self-hosted instances and AI-triggered automations.
Real financial operations. Sub-90-second document processing. Zero manual entry.
A financial services firm was processing 200+ client onboarding documents per week manually — extracting data, cross-referencing compliance fields and updating client records by hand. 15+ hours of staff time per week.
Automated document intake pipeline using n8n — documents uploaded to a shared portal, AI extracts and validates required fields, flags discrepancies for human review and pushes structured data directly to PostgreSQL and the firm's CRM.
Processing time per document reduced from 12 minutes to under 90 seconds. Staff time reclaimed: 13 hours per week in the first month.
