Custom CRM on Twenty
Build a CRM around how your team works.
Twenty provides a production-ready CRM foundation with AI built into the platform.
3Trees works with your team to design the data model, workflows and custom capability around how your organisation operates, then carries the system through implementation and continued development.
Where you are starting
A modern route to a better-fitting CRM.
Modern CRM platforms and AI-assisted delivery make it more practical to shape a dependable system around how an organisation works, without accepting a fixed product or building everything from scratch.
Considering Twenty or replacing another CRM
Your current CRM may be restrictive, fragmented or difficult to trust. Start by defining what the future system needs to support and what should be preserved or migrated.
Already using Twenty
Twenty is already in place, but the data model, workflows or specialist functionality need to go further. Start by identifying the changes that will make the system work better for the team.

Twenty combines an open-source foundation with no-code configuration, modern developer tooling and native AI capabilities, enabling faster iteration.

What can be shaped
Your records. Your logic.Your way of working.
A genuinely custom CRM can reflect the records and relationships your organisation depends on, the stages and decisions they move through, and the actions people need to take. That structure also gives automation and AI dependable operational context.
Your records and relationships
Define the records that matter to your organisation, how they connect and the history your team needs to understand.
Your processes and decisions
Set your own stages, review points, approvals, ownership and next actions instead of forcing the work through a generic sales pipeline.
Your workflows and interfaces
Shape views, record pages, actions, handoffs and automations around how different teams need to work.
AI grounded in your CRM
Give AI assistants and agents structured records, relationships, permissions and workflow context to work within, with that context available to MCP-compatible tools where appropriate.
