Quartal Hub is the AI-native control panel for entrepreneurs and Financial Management experts building agentic businesses. Manage AI agents, their workflows and the conversations between humans and agents — with accounting, invoicing, banking and payroll built in.
Now piloting with selected Advisors and Enterprise customers in Finland. We take a limited number of early adopters: register and tell us what you would like to do. Already have a test account? Sign in.
Who Is It For
From one AI-native company to advisors and software vendors serving thousands of customer companies.
Company
For entrepreneurs and early adopters of agentic AI, building an AI-native company. Manage AI for your own company.
Advisor
For accountants, auditors, payroll experts and consultants in financial management. Manage AI for hundreds of customer companies.
Enterprise
For SaaS software and larger advisor organizations: Quartal Hub embedded white label into your own product and brand. Manage AI for thousands of customer companies.
One Place for Agents, Workflows and People
Create agents that combine plugins or have custom skills, tools and widgets.
Put them to work in channels next to your team and your customers — and stay in control of what they can do and what they cost.
Stay in Control of Agents and Cost
Conversations, models and permissions are managed in one place, for one company or for hundreds.
Channels
Where humans and AI agents work together. Like a Slack channel, a channel holds several conversations, and both people and AI agents take part in real time. Underneath, Quartal Messages is optimized for agent data: tool calls, LLM reasoning and token cost are stored as part of the thread.
Model Independence
Pick the right model for each task — and change it later. Models evolve at an unprecedented pace, token pricing matters, and many look at European sovereign or open-weights models. Stay provider independent, and use evals to make sure your prompts, skills and tools still work when you switch.
Permissions and Cost
Decide who — and which agent — can do what. Control which people and agents can access which channels, which tools agents may use, and set token and cost limits. Advisors get the same controls over hundreds of customer companies, with company groups, roles and invoicing reports for token costs.
Four Base Technologies, One Easy Package
Quartal Hub brings together the base technologies to run AI agents for hundreds of customer companies, in one easy-to-use package:
Always included for registered companies. In the Enterprise tier you may embed them into your own product — customized and even hosted in-house.
Quartal Harness
Let Business Experts Control Your Agents
A multi-player harness to manage your agents for all your customers.
Managing AI agents is not a software project, it is more like managing people: hiring new agents and models, training them with skills, controlling their costs and checking their work. Quartal Harness does this for dozens of advisors and hundreds of agents, serving thousands of customer companies.
- Resources and Context Models, plugins, tools, skills, files, permissions, memory and context.
- Monitoring Chat history, LLM reasoning, audit trail and token consumption tracking.
- Process Build workflows, secure, monitor, invoice — and repeat.
- Sandbox Every agent works in the sandbox of one company, so data never spills over between customers.
- Model Independence Choose the model per task, from the leading AI providers to European sovereign and open-weight models, with evals to keep your agents working when you switch.
Quartal Harness lets business people — not just developers — control their AI agents.
Quartal Messages
Communication Between Humans and Agents
A modern and secure real-time threaded chat, optimized for hundreds of customers and their advisors together with AI agents.
Every party is authenticated, and all the conversations are owned by the customer company.
- Humans First Not just an AI chat: designed first for communication between humans, customers and experts, like Slack, Teams or email.
- Agents and Humans Agents take part in the conversation as defined by the experts:
either directly, like in ChatGPT, or by supporting the customer–expert conversation
(
@agent do this). - Advanced UI Agents can show widgets in the thread: reports, forms and other interactive user interfaces.
- Connectors Connect a message thread to Slack, email, WhatsApp and more.
- White Label Embed it into your own web site, app or service.
Quartal IAM
European Auth for Service-as-Software
European authentication and authorization for Service-as-Software.
- Strong Auth People sign in with national strong authentication — bank credentials and mobile ID — and then with high-security methods such as WebAuthn and FIDO2. Everything is logged, traceable and auditable.
- KYC / KYB Companies and their representatives are verified from the company registry and Suomi.fi authorizations.
- Built for Advisors Authorization optimized for managing hundreds or thousands of customer companies: customer groups, advisor teams, roles and row-level security.
- GDPR Privacy and security built in, especially for payroll and HR, and everywhere else you need it.
- Agents The same security rules for agents and automations as for people, with additional rules for tools, credentials and context.
- Industry Standards Single sign-on and other features built on industry standards — OAuth 2.0, OpenID Connect, SAML — on the leading open-source IAM platform, Keycloak.
We implement national and European standards. In Finland this includes:
Quartal Plugins
Define Agentic Logic Once, Use It from Anywhere
Plugins package the business logic for agents: tools, widgets, agent skills and agents that let models act according to local legislation, norms and processes.
- Batteries Included Quartal Hub comes with the financial management plugins: accounting, invoicing, expenses, bank connections and more.
- Your Own and Others' Add partner and community plugins from the marketplace, or package your own.
- Open Source Quartal Plugins is open source (MIT): anyone can build plugins, publish them in the Hub and use them from any environment.
- No Lock-In Built on open standards such as MCP and OData: build your own AI solutions with Microsoft Copilot, OpenAI Agents SDK, Google Gemini, Anthropic Claude or n8n on top of the same data and plugins.
