Try the client-access workflowHOW TO CHOOSE
Choose the access workflow that matches the work you have to deliver.
Use the operating constraint—not the longest feature list—to make the decision.
Leadsie is designed specifically for client access. Its official materials describe one-link requests, a dashboard, access troubleshooting, and a broad catalog that includes Meta, Google, TikTok, LinkedIn, Shopify, and more. That specialist breadth is valuable for agencies that routinely request access across many customer platforms.
Spacebrain Client Connections takes a focused approach. It is included with Pro and Agency and currently helps agencies send guided Meta access requests, track progress, follow up, and keep the connection alongside the client workspace. That reduces the gap between onboarding access and the delivery workflow the team uses next.
The right choice depends on the exact client onboarding path. List every platform and asset you need, identify the person who can approve it, run the same request with a representative client, and measure completion, follow-up effort, and how easily the team can begin delivery once access is granted.

LOWER-RISK MIGRATION
A practical path from Leadsie to Spacebrain
Prove one revenue workflow before moving the rest of the operation. Each stage should have an owner, success criteria, and a rollback point.
View the four-step migration plan
- 01
Protect the current operation
Export the records and configuration your team relies on in Leadsie. Inventory fields, automations, integrations, consent state, owners, calendars, and reporting before changing anything.
- 02
Rebuild one revenue path
Choose one important acquisition source and reproduce the complete path from first inquiry through qualification, booking, routing, and CRM ownership.
- 03
Test both paths with the same inputs
The right choice depends on the exact client onboarding path. List every platform and asset you need, identify the person who can approve it, run the same request with a representative client, and measure completion, follow-up effort, and how easily the team can begin delivery once access is granted.

Cut over only after validation
Confirm record counts, response behavior, permissions, reporting, opt-outs, failure handling, and human handoffs. Keep a documented rollback window before retiring the old workflow.

Frequently asked questions
Leadsie alternative questions
Answers for teams evaluating fit, migration scope, and the right way to run a product trial.
Is Spacebrain a complete replacement for Leadsie?
Not for every agency. Leadsie offers broader multi-platform access-request coverage. Spacebrain Client Connections is the stronger fit when your current requirement is guided Meta access onboarding that stays connected to your Spacebrain client workspace and delivery flow.
What makes Spacebrain the more modern option?
Spacebrain is built on a modern, cohesive AI-native architecture, so CRM context, conversations, automation, and new AI capabilities evolve together instead of being added across older product layers. The platform is designed for rapid iteration, with customer feedback feeding directly into frequent releases and workflow refinements.
What are Client Connections in Spacebrain?
Client Connections lets Pro and Agency accounts send a client a guided request for the Meta access required for approved agency work, track its status, follow up when incomplete, and keep the connection with the client workspace.
Which Spacebrain plan includes Client Connections?
Client Connections is included with Pro and Agency. It is not included with Free or Starter.
Which platform should I choose for Google, TikTok, or other non-Meta access?
Verify the supported access types before choosing. Leadsie publishes a broad catalog across multiple platforms, while Spacebrain Client Connections currently focuses on Meta access requests.
Can an agency use Spacebrain and Leadsie together?
Possibly. An agency may use Client Connections for the Meta access flow it runs in Spacebrain and a specialist tool for access types not currently supported. Document ownership, client communications, and the source of truth before operating both workflows.
