Glasscubes

What Glasscubes does

Glasscubes Limited is a UK-based SaaS company operating a cloud-hosted collaboration and client portal platform on AWS, headquartered in London with a registered office in Buckinghamshire. Founded in 2011, the company has spent 14+ years building a vertically specialised product set aimed primarily at UK accounting firms, with adjacent exposure to legal, public sector, charities, and IFAs. The core platform comprises Online Workspaces, Client Portals, File Sharing, Team Collaboration, Task & Project Management, Forms & Workflow, and Intranet/Extranet modules, augmented by accounting-specific service-line modules for Personal Tax, Audit & Accounts, Payroll, and Making Tax Digital compliance. A 2024 AI-powered client portal adds automated missing-data detection, NLP-based reply organization, and automated reminders.

Underlying technology is built on AWS with UK-only data centres distributed across at least three physical locations, offering SSL encryption, data-at-rest encryption, 30-day versioned backups, cold storage archiving, and 99.999999999% durability. Enterprise features include SAML 2.0 single sign-on (Azure/Entra AD, ADFS, AWS SSO), two-factor authentication, a REST API, and a Desktop Connect application with MSI installer support.

The business model is a B2B subscription SaaS with two components: an Account Fee payable in advance and a per-User Fee billed monthly in arrears (or annually with a discount). Storage overage and a one-time custom URL setup fee are supplementary revenue streams. Distribution combines a self-serve 30-day free trial with sales-assisted enterprise engagement, telephone sales, and invoice-based contracting for 6/12/24-month terms. Customer base is reported as hundreds of UK accounting firms, with named enterprise customers including Menzies LLP, Johnston Carmichael, Haines Watts, PKF Smith Cooper, PKF Francis Clark, and UHY. The company is privately held, bootstrapped, and operates without disclosed external funding.

Direct peers

• Karbon: Workflow and practice management platform built specifically for accounting firms, with email integration, client communication, workpapers, and project tracking. Comparable to Glasscubes' accountant service-line approach but oriented more toward internal team workflow than client-facing document collection.
• Liscio: Client collaboration platform for accounting firms offering secure messaging, file sharing, and document requests. Directly overlaps with Glasscubes' Client Portal and secure external collaboration capabilities for UK and US accounting firms.
• Canopy: Practice management suite for accounting firms including client CRM, document management, workflow automation, and a client portal. Closely comparable to Glasscubes' accountant service-line modules at the practice-wide workflow level.
• Practice Ignition: Client engagement, proposal, and billing automation platform for accounting and bookkeeping firms. Comparable as an accountant vertical SaaS, though focused on engagement letters, proposals, and recurring billing rather than document collaboration.
• TaxDome: All-in-one practice management platform for accounting firms combining a client portal, document management, workflow automation, invoicing, and CRM. Closely comparable to Glasscubes' accountant-focused client portal and service-line modules, though TaxDome also includes billing and a broader practice OS.
• Suralink: PBC list management, information request tracking, and engagement letter automation purpose-built for accountants and auditors. Directly comparable to Glasscubes' Information Request product and the core 'automated chasing of client information' use case.
• SmartVault: Cloud document management and client portal built specifically for accounting professionals with accountant-focused workflow templates. Directly comparable to Glasscubes' file sharing, document management, and accountant-facing client portal capabilities.

Broad incumbents

• Box: Enterprise cloud content management and secure file sharing platform. Comparable to Glasscubes' file sharing and secure collaboration feature set, but Box targets larger enterprises across many verticals rather than specialising in UK accounting workflows.
• Microsoft SharePoint: Enterprise content management and team collaboration platform inside Microsoft 365, used by many accounting firms for document and intranet workflows. Glasscubes explicitly markets itself as an 'easier-to-configure alternative to SharePoint' for organisations that find SharePoint too complex.
• Citrix ShareFile: Secure cloud file sharing and document collaboration platform with industry-specific workflows for accounting and financial services. Overlaps directly with Glasscubes' file sharing and accountant client portal capabilities, though ShareFile serves a broader enterprise cross-industry base.
