You Don't Have to Replace Everything

The KMT Stack works alongside your existing tools -- or replaces them entirely. Your call.

Have a CRM you like?

Keep it. We'll connect Mautic, Matomo, and n8n to it.

Just need email marketing?

We can deploy Mautic on its own.

Want the whole stack?

We'll set up all four platforms, fully integrated.

Same managed infrastructure. Same flat pricing. You choose what goes on it.

The KMT Stack -- Your Private MarTech Cloud

Four powerful open-source platforms, fully managed on private infrastructure.

Mautic: Marketing Automation

Everything HubSpot and Marketo offer -- email campaigns, lead scoring, landing pages, multi-channel marketing, behavioral tracking -- without the per-contact pricing trap that punishes you for growing your list.

  • Unlimited contacts -- pay for infrastructure, not list size
  • Visual campaign builder with drag-and-drop workflows
  • Advanced lead scoring and behavioral tracking
  • Complete data ownership on your infrastructure

Matomo: Privacy-First Analytics

Your analytics data stays on your servers, never touches Google, and gives you complete, unsampled visit data -- with flexible privacy controls you can tune to your jurisdiction.

  • 100% data ownership on your servers
  • Configurable privacy and consent controls that fit your jurisdiction
  • No data sampling -- see every visit, every session
  • Configurable to meet GDPR, CCPA, and HIPAA requirements

n8n: Workflow Automation

Build powerful automations between your apps with a visual workflow builder -- without the unpredictable task-based billing that makes Zapier costs spiral out of control.

  • 400+ integrations including CRMs, email, databases, and APIs
  • Execution-based pricing -- one run = one execution, unlimited steps
  • AI-ready with native LLM nodes
  • Self-hosted -- your data stays on your infrastructure

Twenty: Open-Source CRM

A modern, beautifully designed CRM built for the way teams actually work -- with full data portability, no per-seat pricing, and an interface your team will want to use.

  • Contact and company management with custom fields
  • Pipeline tracking with visual Kanban boards
  • API-first architecture for seamless integration
  • No vendor lock-in -- export everything anytime

100% Data Ownership

Your data lives on servers you control. Export anytime. No hostage situations.

Complete Privacy Compliance

Privacy controls that adapt to your jurisdiction. Your visitor data never leaves your infrastructure.

Predictable Costs

Flat infrastructure costs. No per-contact fees. No task-based billing surprises.

The KMT Stack vs. The Typical Proprietary Stack

Proprietary Stack The KMT Stack
Data Ownership Vendor owns your data 100% yours, on your servers
Pricing Model Per-contact + per-task fees Flat infrastructure + management
Privacy Data shared with third parties Data never shared externally
Data Sampling Sampled above query limits Complete, unsampled data
Exit Strategy Vendor lock-in Export anytime, no lock-in

You Get the Tools. We Handle the Complexity.
