The AI workspace
for tax and advisory firms.

One place for your clients, their documents and your whole team.
Ask Maven, and get work your team can check and send.

Everything your firm needs, in one place.

Maven brings the three things every piece of client work depends on into one workspace.

Every client’s files

Add returns, invoices and letters once. Maven reads them, and answers built on them show which file they came from.

Your firm’s way of working

Write down how your firm does a job once. Maven follows those steps on every client, every time.

Shared Spaces for your team

Give each client a Space. Your team talks, shares files and asks Maven together, in one conversation.

Shared Spaces

Work on every client together.

Your team, the client’s files and Maven, in one conversation. Drafts stay marked as not reviewed until a reviewer approves them.

    Kibo’s Q3 VAT is due on the 20th. Juma, can you take the reconciliation?

  2. JumaAssociate · 09:15

    @Maven match the Q3 sales invoices to the EFD receipts.

  3. Maven09:16

    Done. 3 invoices have no matching EFD receipt, so TZS 4.2M of input VAT is at risk. The reconciliation is ready for Amina.

One Space for each client

Everyone on the job shares the same files and the same conversation. Drafts stay with their author until a reviewer approves them and they are shared.

Ask Maven where you talk

Type @Maven in the conversation. It answers using that client’s files, so the whole team sees the work.

A reviewer signs off

Drafts go to a colleague you choose. They approve or ask for changes, and every version is kept.

Playbooks

Your firm’s rules, tone, format, checklists and standards, built in.

A playbook is your firm’s way of doing a job, written down once. Maven follows it on every client, so the work sounds like you and keeps to your rules.

Client advice letter

How Hassan & Partners writes to clients

  1. 1
    Tone

    Formal and warm. Plain English, no jargon. Address the client by name.

  2. 2
    Format

    The answer first. Then the law. Then what the client should do next.

  3. 3
    Rules

    Always quote the section of the Act. Never promise an outcome with TRA.

  4. 4
    Sign-off

    A manager reads it before it goes to the client.

Next step: please send us the signed sales ledger by Friday. We will prepare the objection for you to sign.2

Kind regards,

Write it once

Put down how your firm does a job, the way you would teach a new hire. Plain words, no setup.

A partner approves it

A firm playbook is checked before anyone can use it, so only your real methods reach client work.

Maven follows it every time

Change a rule today and tomorrow’s work follows it. Every client gets the same standard.

Privacy

Every client file stays where it belongs.

Maven only works with the files you give it, for the people you choose. One client’s documents are never used to answer for another.

Each client has its own walls

Only the people you add can open a client. Everyone else in the firm can’t see it.

Private until you share

Your own Projects are yours alone. You choose what reaches the team, and when.

A person sends every reply

Maven drafts. Your team checks, approves and shares. Every version shows who approved it.

Never used to train AI

Your files help with your work, and only your work. They don’t teach anyone’s model.

Security

Enterprise-grade security and controls

Your firm decides who sees each client, what Maven can read and who signs off. Every control a firm’s IT team expects is built in: SAML single sign-on, audit logs, IP allow-listing and data lifecycle management.

Talk to us
What is Maven?

Maven is an AI workspace for tax and advisory firms. Your team keeps each client’s documents, your firm’s way of working and the conversation in one place, and Maven drafts the work for your people to check and send.

Who is Maven for?

Tax consultancies, accounting practices and business advisory firms. We are starting with firms in Tanzania, so Maven is built for work like VAT returns, corporate tax computations and replies to TRA.

What kind of work can Maven help with?

Tax computations, VAT reconciliations, advice letters, memos, replies to TRA queries and reviews of client documents. If your team does it often, Maven can help draft it.

Is our client data safe?

Each client has its own access list, so only the people you add can open its files. Your own Projects stay private until you share them, and you can switch AI off for any client.

Will our files be used to train AI?

No. Your files are used to do your work and nothing else. They are never used to train AI models.

AI tools drift from how we work. How does Maven stay consistent with our firm?

You write down how your firm does each job once, as a playbook: the steps, your rules, your tone and format, and the checks before sign-off. An owner or admin approves it, and Maven follows it on every client. When you change a rule, the new version is reviewed before new work uses it, so the work stays the same whoever on your team asks.

Can my whole team work in Maven together?

Yes. Give each client a shared Space. Your team talks, shares files and asks Maven in one conversation, and managers review drafts in the same place.

How do we get started?

Book a demo. We set up your firm, add your team and walk you through a real client job, from the first document to the signed-off reply.
