Bookkeeping
for Swiss SMEs.
Reimagined with AI.
What we do.
Bookkeeping
Stop collecting invoices in shared folders. AI reads and books every document; a certified Treuhänder validates the numbers — financials in days, not weeks.
Tax & VAT
AI prepares VAT and tax filings from your live books; a certified Treuhänder reviews and submits to the ESTV. Deadlines hit, every time.
Payroll
AI runs salaries, deductions and slips on autopilot; a certified payroll specialist signs off — accurate and on time, every month.
24/7 support
Our AI assistant answers 24/7 from your live data — or reach your dedicated Treuhänder for the calls that need human judgement.
Legal
Routine contracts and compliance drafted by AI, reviewed by qualified Swiss advisors — so nothing falls through the cracks.

Your favorite tools connected.
Mithril integrates seamlessly with your existing software and lets you complete recurring tasks in a fraction of the time.
A Manifesto
Financial infrastructure for the next generation of Swiss companies.
Every company depends on its financial back office. For most Swiss businesses, it still runs on manual work — fragmented tools, weeks of lag, prices that haven't moved in a decade.
We are building Mithril because this foundation can finally be rebuilt. For the first time, software can do the work — read a document, book the transaction, reconcile the account, prepare the filing, keep the books current to the day. Accountants move to judgement. Founders act on numbers they trust.
Switzerland is the right place to build it: small, precise, multilingual, run on trust. The country that set the standard for financial precision should be the one that rebuilds it for this era. Mostly invisible. Deeply reliable. Strong enough to build a company on.
Mithril exists to rebuild the financial operating layer for Swiss companies.
The next generation will be built on it.
