Software & Mobile App Development Company in Switzerland
Custom software, mobile app and AI development for Swiss companies, built around the revised FADP, TWINT payments and four national languages.
- NDA & full IP ownership
- Senior engineers
- Working hours that overlap with Switzerland
Swiss buyers are demanding in a very particular way: they expect precision, documentation and data handled with care, and they rarely forgive sloppy releases. Sigmato works as a software development company for Switzerland-based organisations that want that standard without paying Zurich day rates for every line of code. We design and build mobile apps, web platforms, SaaS products and AI features for banks, insurers, life-science firms, retailers and start-ups in Zurich, Geneva, Basel and Lausanne, with engineering in Bengaluru and a branch office in Fleet, Hampshire.
What Swiss Teams Ask Us to Build
Most Swiss engagements start with a product owner who already has an internal IT department but not enough hands for a new initiative. Typical requests include:
- Customer-facing mobile apps for retail banking, insurance self-service, loyalty programmes and transport. iPhone usage is high in Switzerland, so we usually polish the iOS experience first and ship Android in the same release train.
- B2B SaaS platforms for wealth management reporting, compliance workflows and supply-chain visibility, with tenant isolation and audit logs from day one.
- Applied AI: document extraction for underwriting, internal knowledge assistants that answer in German, French or Italian, and anomaly detection for operations data.
- Blockchain and tokenisation work for firms in the Zug and Zurich digital-asset scene, from smart contracts to custody dashboards.
Data Protection under the Revised FADP
Switzerland is not in the EU, so GDPR is not the starting point. The revised Federal Act on Data Protection (revFADP, or nDSG in German) has applied since 1 September 2023 and is supervised by the Federal Data Protection and Information Commissioner (FDPIC). It shares many ideas with GDPR but has its own vocabulary and duties. In practice we plan for:
- Privacy by design and by default, which the revFADP makes explicit: minimal data collection, sensible retention periods and privacy-friendly default settings.
- A record of processing activities and data protection impact assessments for high-risk processing such as profiling or health data.
- Cross-border transfer checks. Moving personal data to India or any country not on the Federal Council’s adequacy list needs safeguards such as standard contractual clauses adapted for Swiss law. Where clients prefer, we deploy to Swiss cloud regions in Zurich or Geneva and work inside their environment.
- FINMA expectations for regulated financial firms, especially around outsourcing, operational resilience and banking-client confidentiality. If you hold a FINMA licence, your outsourcing policy shapes how we access systems and data.
Our AI data privacy checklist explains how we keep prompts, embeddings and training data inside the boundaries your legal team signs off.
Four National Languages, One Codebase
A Swiss product often has to launch in German, French and Italian at once, and public-facing services sometimes add Romansh or English. We set up internationalisation before the first screen is designed, so translators work from managed string files rather than screenshots. A few local details we handle as standard:
- Swiss Standard German uses “ss” instead of “ß”, so de-CH needs its own locale rather than a copy of de-DE.
- French labels run longer than German ones in some components and shorter in others; layouts are tested in all three languages.
- Prices display in CHF with the apostrophe thousands separator (CHF 1’250.00), and dates follow the dd.mm.yyyy pattern.
Payments: TWINT, QR-bill and Cards
TWINT is the mobile wallet Swiss consumers reach for first, both in apps and at the till, so a checkout without it feels foreign. We integrate TWINT through payment service providers such as Datatrans, Payrexx, Wallee or Stripe, alongside Visa, Mastercard, PostFinance Card, Apple Pay and Google Pay. For B2B invoicing we generate Swiss QR-bills, which replaced the old orange and red payment slips, and can connect to ISO 20022 banking interfaces for reconciliation.
Sectors We Know in Zurich, Geneva, Basel and Lausanne
- Zurich: private banking, insurance and a growing start-up community around ETH Zurich. We build client portals, advisory tools and fintech apps with strong authentication.
- Geneva: commodity trading, wealth management and international organisations that need multilingual, accessibility-conscious portals.
- Basel: pharmaceutical and life-science companies running clinical, laboratory and medical-affairs applications where validation and traceability matter.
- Lausanne: EPFL-linked deep-tech spin-offs, plus food, sports-federation and hospitality businesses around Lake Geneva.
Working Hours That Suit a Swiss Day
Switzerland runs on Central European Time. Bengaluru is three and a half hours ahead in summer and four and a half in winter, which means our engineers are already mid-shift when your office opens. You get a shared window of roughly five hours from your morning until early afternoon for stand-ups, reviews and workshops. Our UK branch sits just one hour behind you, which helps for contract discussions and steering meetings. Afternoon feedback is picked up first thing the next Indian morning.
Indicative Budgets for Swiss Projects
| Project type | Indicative range (USD) | Typical duration |
|---|---|---|
| Clickable prototype and technical spike | $6,000 – $15,000 | 3–5 weeks |
| Bilingual or trilingual mobile MVP | $30,000 – $85,000 | 3–5 months |
| Regulated web platform or SaaS product | $70,000 – $200,000+ | 5–10 months |
| Dedicated developer (monthly) | $3,500 – $6,500 | Ongoing |
These are indicative figures only; we can quote in Swiss francs (CHF) on request, and the final price depends on scope, integrations and compliance work.
Frequently Asked Questions
Can our personal data stay in Switzerland?
Yes. AWS, Microsoft Azure and Google Cloud all operate Swiss regions, and we can deploy there or into your own tenant. Developers can work on anonymised or synthetic test data so production records never leave the country.
Do you work with FINMA-regulated companies?
We can. We follow your outsourcing and access policies, provide documentation for your risk assessment, and accept the audit and information rights your compliance team requires in the contract.
Is it possible to add TWINT to an existing app?
Usually, yes. If your payment provider already supports TWINT, adding it is often a matter of days for the integration plus testing time. If not, we help you compare Swiss-focused providers.
Which contract law applies?
We are open to Swiss or English law and to your standard master agreement. Intellectual property is assigned to you, and source code lives in your repositories.
