One operating layer for service businesses.
Tallie connects finance, delivery, CRM, meetings, email, tasks, and time into one assistant-led workspace. It helps CFOs, Finance Directors, COOs, and professional-services leaders see what changed, what needs attention, and what happens next.
Give service teams a clearer operating rhythm.
Most service businesses do not have a single operating system. Client promises live in meetings, inboxes, CRM notes, project plans, timesheets, finance tools, and people's heads. Leaders end up asking for updates instead of seeing the work.
Tallie turns those scattered signals into an assistant-led workspace. It prepares follow-ups, flags delivery risk, connects CRM and project context, helps with finance ops, and keeps the weekly operating rhythm moving.
The product direction is deliberately practical: monthly SaaS, guided early access, and human-approved workflows that make the team faster without hiding important decisions.
What we believe
Make the work visible
Service businesses run on promises made across meetings, email, CRM, delivery, finance, and time. Tallie brings those signals into one operating picture.
Assist before automating
The assistant should prepare the next action, show the context, and ask for review where it matters. Sensitive work stays human-approved.
Start with real workflows
Meeting follow-up, email triage, project review, CRM hygiene, invoice chasing, time review, and weekly operating rhythm are the places where value shows up quickly.
Fit the way teams already run
Tallie is a monthly SaaS operating layer, not a rip-and-replace of accounting, CRM, project management, email, or meeting tools.
Built by Mercury Labs
Tallie is built by Mercury Labs, a London-based AI engineering studio that designs and deploys practical AI for businesses.
Our team of data scientists and full-stack engineers has spent years building AI products across fintech, healthcare, manufacturing, and market intelligence — for organisations including PrimaryBid, Augmentive, MTC, HVM Catapult, and Forestreet.
As an approved supplier through the Crown Commercial Service, we've also worked directly with the UK Government on AI projects, partnering with Innovate UK and other public sector bodies to deliver AI at scale in regulated contexts.
Tallie is the platform we kept wishing existed every time a customer asked for AI productivity without handing over their data, their model choice, or their cost base. So we built it — and we deploy it the way we wish all enterprise software was deployed: with a real engineer in the room.
Based in Eccleston Yards, London.
