Financial software, thoughtfully made.
We are a team in Lausanne building financial software that combines modern design with real depth — so Swiss businesses no longer have to choose between simplicity and completeness.
We come from strategy, operations, and corporate finance — and we are deeply passionate about what we are building. We have seen firsthand how the right tools can transform the way a company runs its accounting, understands its numbers, and makes better decisions. That conviction drives every feature in Mast: intuitive design, AI that adds real value, and a modular architecture that works whether you are a freelancer or managing a growing team.
Mast brings analytics, budgeting, and fiduciary collaboration into a single workspace — alongside QR invoicing, multi-currency bookkeeping, and full Swiss compliance. Not a generic tool adapted for Switzerland, but one built here, for here.
" We set out to build the platform we wished existed.
What guides everything we build
Swiss Quality
We care about getting the details right. Every calculation, every report, every workflow is designed to the standard Swiss businesses expect — precise, reliable, and built with care.
Privacy First
Your financial data stays in Switzerland. We treat data protection not as a compliance checkbox, but as a fundamental design principle from day one.
Built to Last
We think in years, not quarters. Mast is designed to grow with your business — a stable foundation you can rely on, not a tool you will need to replace.
Less admin. More clarity.
Your time back
Bank reconciliation, VAT returns, payment runs, depreciation schedules — the repetitive tasks that fill your week are largely automated, so your team can focus on what matters.
Everything in one place
Invoices, bank feeds, expenses, and reports — all connected in a single workspace. No more switching between tools or reconciling spreadsheets to see the full picture.
Numbers that tell a story
Real-time dashboards, KPI tracking, and cash forecasting that turn your financial data into clear, actionable insights — ready for your next board meeting or strategic decision.
Processes that grow with you
Approval workflows, expense submissions, multi-entity mandates — the tools growing companies need, built in from the start. No workarounds, no outgrowing your software.
Join our beta testers
We are building a first community of companies and fiduciaries to test Mast in real conditions. Swiss-hosted from day one.
