FuseBase preview

AI-native client portal platform

FuseBase is an AI-native client portal and client collaboration platform for agencies, consultants, and other client-facing teams. It combines internal workspaces for team operations with external workspaces that function as branded client portals, so collaboration and delivery can live in one system without requiring clients to learn a traditional project management tool.

The site emphasizes secure sharing, brand customization, and the ability to build client-facing apps that extend services beyond a standard portal. It also adds AI agents that can work from the content in your workspace, helping teams answer questions, automate routine work, and support delivery across internal and external workflows.

Key capabilities

Internal and external workspaces

FuseBase separates internal team workspaces from external client portals so teams can manage their own operations while exposing only the parts clients or partners need.

Client portal delivery

External workspaces are presented as client portals with protected access, branded presentation, secure file sharing, live chat, forms, surveys, and white-label support.

Client-facing app building

The product supports custom apps that can be connected to domains or subdomains, letting teams extend services beyond a standard portal layout.

AI agents and content actions

The homepage highlights AI agents that can answer questions, take action, and automate busywork from content already in the workspace, with both prebuilt and custom agent options.

Operational collaboration tools

The pricing page lists workflow and workspace tools including task management, file management, calendar view, Kanban boards, task lists, dashboards, content templates, and workflow automation.

Usage-based plan structure

Pricing details show multiple tiers, add-ons, and plan controls such as members, portals, clients, AI requests, automation runs, and transcriptions, which supports different team sizes and usage levels.

Common ways teams use FuseBase

  • Client onboarding and delivery

    Create a secure external workspace for clients or partners that looks like a branded microsite, gives them protected access, and centralizes files, updates, and collaboration in one place.

  • Internal team operations

    Set up an internal workspace for sales, processes, notes, files, and collaboration so the team can stay organized while keeping client-facing materials separate.

  • Partner and deal collaboration

    Build a partner, vendor, or deal space to share materials, track mutual action items, and maintain a controlled environment for outside stakeholders.

  • AI-assisted support and automation

    Use AI agents to answer questions from workspace content, automate routine steps, and reduce manual busywork inside the tools your team already uses.

  • Productized service delivery

    Extend your service with custom or prebuilt client-facing apps connected to your domain or subdomain when a standard portal needs more tailored functionality.

FAQ

How does FuseBase work for client collaboration?

FuseBase describes the product as having internal workspaces for your team and external workspaces for clients and partners. External workspaces act as client portals with protected access and a microsite-style experience, so clients do not need to learn a project management tool to collaborate.

What is the difference between a client portal and a project management tool?

The site positions FuseBase client portals as different from project management tools because they are designed for external collaboration with a simpler client-facing experience, branding options, and protected access rather than a heavy internal workflow interface.

Can I white-label FuseBase with my own brand?

Yes. The homepage says FuseBase can be white-labeled through a subdomain, and portals can be customized to look different. The pricing page also lists white label and custom domain support on higher tiers.

Can I build client-facing apps inside FuseBase?

FuseBase says you can build internal apps and client-facing apps inside the platform, connect FuseBase apps to domains or subdomains, and extend services with AI-native apps. The site also says it supports integrations and third-party integrations on paid plans, but it does not publish a full connector list on the pages reviewed.

What pricing options does FuseBase offer?

The pricing page says FuseBase offers Solo, Essentials, Advanced, and Unlimited plans, plus add-ons such as Client Portal, Automation, Transcribing, and FuseBase AI. It also offers a free plan and a free trial flow, while some higher-usage limits and some plan details require contacting sales.
