Overview

What this migration involves

Moving from Membrain to Twenty CRM is a migration from a structured-process SaaS platform to an open-source, self-hosted CRM with a flexible custom object model. Membrain organizes B2B sales data around guided selling workflows across Companies, Contacts, Prospects, Sales Projects, and Account Growth Projects, each with their own GUID-prefixed custom field schemas. Twenty CRM uses a Company-Person-Opportunity core with support for building custom objects directly in the UI. The key challenge on the Membrain side is resolving the CustomField{GUID} naming convention before export, remapping Lite account ownership to active Full accounts, and confirming which modular products are licensed so the export schema matches what exists. On the Twenty side, all custom fields must exist in Settings before CSV import because Twenty creates records, not fields. Automations, Flows, Content Hub assets, and Tickets (add-on module) do not migrate; we deliver a written inventory of every automation and extension requiring rebuild in Twenty's workflow engine post-migration.

Why teams make this switch

Two sides of the same decision

Leaving

Membrain logo

Membrain

What's pushing teams away

  • API is gated behind a paid add-on module and rate limits are not publicly documented, making automated migrations and integrations difficult to plan.
  • BI-level reporting is a known gap — customers needing multi-funnel attribution or executive dashboards outgrow what Membrain offers out of the box.
  • The structured process enforcement that attracts methodical sales teams feels restrictive to reps used to flexibility, creating adoption friction during onboarding.
  • Teams with fewer than 5 reps or deals under 60 days often find the methodology overhead disproportionate to the value delivered.
  • Integration count is limited compared to HubSpot or Salesforce — organizations with 10+ existing tools frequently hit a ceiling.

Choosing

Twenty CRM logo

Twenty CRM

What's pulling them in

  • Top open-source CRM on GitHub with 40.6K stars, giving teams full source code access and infrastructure ownership without per-feature licensing surprises.
  • Free self-hosting under AGPL-3.0 means unlimited users and custom objects for the cost of cloud infrastructure alone, typically $20–100/month.
  • Pricing page explicitly mocks competitors for charging add-on fees for API access, webhooks, and workflows — transparency that resonates with RevOps teams burned by Salesforce.
  • Unlimited custom objects and fields with no price impact, letting teams shape the data model to their business rather than forcing business into rigid schemas.
  • Modern TypeScript/React/PostgreSQL stack means developer-led teams can extend, self-host, or integrate without fighting legacy architecture.

Object mapping

How Membrain objects map to Twenty CRM

Each row shows how a Membrain object lands in Twenty CRM, including any object-level transformations, lookup resolution, or schema-design dependencies.

Typical mapping — final map is confirmed during the sample migration step.

Membrain

Company

maps to

Twenty CRM

Company

1:1
Fully supported

Membrain Companies map directly to Twenty Companies. Standard fields (name, address, industry, website) migrate to Twenty Company fields by name match. The company domain becomes the Website field and serves as a dedupe key during import. CustomField{GUID} values on Companies resolve via the GUID-to-label lookup built from Membrain's custom field definitions during discovery. Company must import before People so the Company lookup relationship resolves on Contact insert.

Membrain

Contact

maps to

Twenty CRM

People

1:1
Fully supported

Membrain Contacts map to Twenty People. Email address is the dedupe key; contacts with duplicate emails are merged or flagged for review based on activity recency. Standard fields (firstName, lastName, email, phone, jobTitle) map to Twenty People fields by name. The company-to-contact link migrates as the People.CompanyId lookup resolved against the imported Company records. Custom field GUIDs resolve via the lookup table; date and phone formats standardize to ISO 8601 and E.164 respectively.

Membrain

Prospect

maps to

Twenty CRM

People (or Lead if created)

1:many
Fully supported

Membrain Prospects live in the Prospecting product module with their own lifecycle stages distinct from Contacts. Where the customer uses Prospects as unqualified pipeline entries, we map them to Twenty People records with a custom pipeline_stage field carrying the original Prospect stage. If the customer maintains strict Contact-Prospect separation in Twenty, Prospects map to a custom Status field on People. Prospect-specific custom fields migrate to matching People custom fields in Twenty's Data Model.

Membrain

Sales Project

maps to

Twenty CRM

Opportunity

1:1
Fully supported

Membrain Sales Projects map to Twenty Opportunities. The Sales Project's Company and primary Contact links migrate as Opportunity.CompanyId and a custom peopleId field resolved against the imported Company and People records. Stage name, probability, expected close date, and value migrate to Twenty Opportunity fields. Pipeline stage definitions require explicit mapping: Membrain's custom stage names (arbitrary per Sales Project type) map to Twenty's Opportunity stage values by position and win-rate intent.

Membrain

Account Growth Project

maps to

Twenty CRM

Custom Object (AccountGrowthProject)

1:1
Fully supported

Membrain Account Growth Projects track expansion and account planning at the Company level with their own workflow and custom fields. Twenty does not have a native account growth or account planning object, so we create a custom AccountGrowthProject object in Twenty's Data Model before import. Custom fields from Membrain map to the new object; the project-to-Company link migrates as a CompanyId lookup. Stage and value fields map to custom fields on the new object.

Membrain

Activity (Appointments, Calls, Notes, Emails, Tasks)

maps to

Twenty CRM

Task, Note, or Event

1:1
Fully supported

Membrain Activities migrate to Twenty Task or Note records depending on type. Appointments map to Event records with startDate, endDate, and location. Calls map to Task with a custom taskSubtype field set to 'Call' and callDuration custom fields. Notes map to Note records linked via ContentDocumentLink to the parent People or Company record. Emails and Tasks migrate as Task records. Activity-to-record links (PeopleId, CompanyId, OpportunityId) resolve against imported records by email or name match before insert.

Membrain

Ticket (add-on module)

maps to

Twenty CRM

Ticket or Custom Object

1:1
Fully supported

Tickets are a Membrain add-on module with their own workflow stages, custom fields, and assignment rules. Twenty does not have a native ticket object in the base install. We map Tickets to a custom Ticket object created in Twenty's Data Model with custom fields for status, priority, assignee (resolved via User email match), and the parent Company or People link. If the customer does not have the Tickets module licensed, this object is absent from the export and skipped.

Membrain

User (Full accounts)

maps to

Twenty CRM

User

1:1
Fully supported

Membrain Full User accounts map to Twenty User (Member) records. We extract owner assignments from every record type (Companies, People, Sales Projects, Activities) and match by email against the Twenty Members list. Owners without a matching Twenty User are placed in a reconciliation queue; the customer's admin provisions missing users before record import resumes. Lite accounts are flagged separately and ownership is reassigned to a designated Full user before migration.

Membrain

Team

maps to

Twenty CRM

Workspace or Custom Group

lossy
Fully supported

Membrain Teams group users and can be assigned as record owners. Team structure is exportable, but team-to-user membership requires explicit mapping because team naming conventions differ between platforms. We export the team hierarchy as a custom CSV and map team assignments to Twenty's workspace permissions or a custom Group object depending on the customer's intended usage.

Membrain

Custom Field

maps to

Twenty CRM

Custom Field

lossy
Fully supported

Every Membrain custom field uses the CustomField{GUID} naming convention on each object context (Companies, Contacts, Prospects, Sales Projects, Account Growth Projects, Activities, Tickets). We query the custom field definitions first to build a GUID-to-label lookup table, then substitute human-readable field names during mapping. Before importing, all custom fields must exist in Twenty Settings Data Model; we create them via Twenty's UI or API before data import begins.

Membrain

Pipeline Stage

maps to

Twenty CRM

Opportunity Stage

lossy
Fully supported

Membrain allows each Sales Project type to define its own stages with arbitrary names, probabilities, and step counts. We extract the complete stage definition from Membrain and map each stage to Twenty's Opportunity stage values by position and win-rate intent. Stage history that exceeds Twenty's default stage field capacity is logged as a custom activity record to preserve the audit trail.

Pair-specific challenges

  • Custom field GUID resolution must precede data export

    Membrain stores custom field values under properties named CustomField{GUID} rather than human-readable names. Every data export from Membrain contains only GUID keys unless the export is enriched with the field definitions. We resolve this by querying the custom field definitions during discovery to build a GUID-to-label lookup table, then applying it as the first transform step before any mapping or import logic runs. If the export is processed without this step, all custom field values are silently dropped or fail validation because Twenty has no field named CustomField{GUID}.

  • Lite accounts cannot own records and must be remapped

    Membrain's Lite user tier cannot own records, trigger automations, or perform batch operations. If a record's owner in Membrain is a Lite account, importing it as-is into Twenty can cause ownership ambiguity or permission failures. We flag all records owned by Lite accounts during scoping and remap ownership to a designated Full user before import. This is a source-of-record issue that must be resolved before any data moves, not a post-import cleanup.

  • All custom fields must exist in Twenty before import

    Twenty's CSV import creates records, not fields. If a Membrain custom field has no matching Twenty field, the import silently drops that column. We create all required custom fields in Twenty Settings Data Model before importing any data. This includes custom fields derived from Account Growth Projects (mapped to a new AccountGrowthProject object) and Ticket custom fields. The Twenty docs explicitly warn that fields must exist before import; skipping this step causes partial data loss.

  • Twenty standard fields are limited and may need manual creation

    A documented GitHub issue (#13953) on the Twenty repository identifies that People and Company objects lack industry-standard fields available immediately on other CRMs (multiple emails, phones with types, jobTitle, department, website, socialProfiles). During migration, we create these fields in Twenty's Data Model before importing so that standard Membrain fields (email, phone, title) have a target. This is not a bug but a known gap in Twenty's base install that affects CRM-to-Twenty migrations broadly.

  • Views, workflows, automations, and Content Hub do not migrate

    Membrain automations (Flows add-on), guided selling step tracking, Sales Project stage enforcement, and Content Hub assets are behavioral and content-layer features that do not have a structural equivalent in Twenty. Twenty's documentation explicitly states that Views, workflows, and permissions must be recreated manually after migration. We deliver a written inventory of every active Membrain automation and workflow step with a description of its trigger, conditions, and actions for the customer's admin to rebuild in Twenty's workflow engine. Content Hub metadata (file names, categories, associated record links) exports as a reference CSV; binary content does not migrate.

Migration approach

Six steps for a successful Membrain to Twenty CRM data migration

  1. Discovery and export schema confirmation

    We audit the Membrain account across licensed products (Prospecting, Active Pipeline, Account Growth, Elevate) and add-ons (Flows, Tickets, Content Hub). We confirm which modules are active because inactive modules produce no export data. We identify all CustomField{GUID} field names by querying Membrain's custom field definitions and build the GUID-to-label lookup table. We extract all record owners, flag Lite accounts for remapping, and inventory the Sales Project pipeline stage definitions including custom stage names and probabilities.

  2. Twenty workspace preparation

    Before any data moves, we create all required custom fields in Twenty Settings Data Model. This includes custom fields matched from Membrain (resolved via the GUID lookup table), industry-standard fields missing from Twenty's base install (multiple phones, emails, jobTitle, department, website), and the AccountGrowthProject custom object with its field definitions. We also invite all team members via Settings Members so that User records exist before owner lookups are resolved during import.

  3. Data export from Membrain

    We export each object type from Membrain in dependency order: Companies (first, because People have a CompanyId lookup), People, Prospects, Sales Projects, Activities, Account Growth Projects, and Tickets. Each export is enriched with resolved field names from the GUID lookup table and includes the original Membrain owner email for User reconciliation. We run a row-count reconciliation against the expected counts per product license before proceeding to import.

  4. Owner reconciliation and User provisioning

    We extract every distinct owner email from the Membrain exports and match against the Twenty Members list. Any owner without a matching Twenty User goes to a reconciliation queue. The customer's admin provisions missing users in Twenty and confirms acceptance of the invitation. We also remap all Lite account ownership to the designated Full user. This step is blocking: OwnerId references must resolve before Opportunity and Activity imports proceed.

  5. Production migration in dependency order

    We load data into Twenty in record-dependency order: Companies first, then People (with CompanyId resolved), then Opportunities (with CompanyId and peopleId resolved), then Activities (Tasks, Events, Notes with parent lookups resolved), then Account Growth Projects (custom object with CompanyId lookup), then Tickets (custom object with assignee resolved). Each phase emits a row-count report before the next begins. We use Twenty's REST API with batch chunking and retry logic for large volumes.

  6. Cutover, validation, and automation handoff

    We freeze Membrain writes during cutover, run a delta migration of records modified during the migration window, and enable Twenty as the system of record. We deliver a reconciliation report comparing Membrain source counts to Twenty destination counts per object. We also deliver the automation inventory document listing every Membrain automation, workflow step, and Content Hub asset with recommendations for rebuilding in Twenty's workflow engine. We support a one-week post-migration window for reconciliation issues raised by the customer's team.

Migrations under 5,000 People, 1,000 Opportunities, and no custom objects land between four and six weeks. Migrations with Account Growth Projects, high-volume activity histories (over 200,000 records), Tickets add-on data, or large GUID-heavy custom field schemas move to eight to twelve weeks because of GUID lookup resolution, custom object pre-creation in Twenty's Data Model, and Tickets-to-custom-object mapping. Discovery and workspace preparation typically take one to two weeks; data migration and cutover take the remaining time.
