The Reality

Why your current tools are holding you back

Manual processes that cost you dearly

Shared Excel spreadsheets, lost emails, paper forms: these manual processes generate errors, duplicates and considerable time waste. Every hour spent re-entering data is an hour lost for your business.

Generic software that doesn't adapt

Off-the-shelf solutions never exactly match your workflows. You pay for features you don't need while missing the ones you actually require. The result: workarounds, frustrations and hidden costs.

Scattered data, no overview

Your information is spread across 5 different tools: a CRM here, a spreadsheet there, emails elsewhere. No single source of truth. Impossible to make informed decisions without manually consolidating data.

Our Approach

What makes ark.swiss different

We are not an agency that makes promises. We build and maintain our own SaaS products. This hands-on experience directly benefits every client project.

Product Builders

4 SaaS in production: ark.stock, ark.flow, ark.plan and Prezntly. We build what we sell — not just consultants who theorize, but developers who deliver and maintain real products.

Flexible Architecture

Multi-tenant SaaS with Stripe billing or dedicated single-client application: we adapt the architecture to your exact need. No one-size-fits-all solution, but a justified technical choice for each project.

Integrated AI

Artificial intelligence where it brings real value: automatic classification, document OCR, automation of repetitive tasks. No buzzwords, concrete measurable results in your daily operations.

Long-term Evolution

We have maintained our own products for years. We know what long-term support really means: security updates, new features, scaling. Your application evolves with your business.

Frequently Asked Questions

Your questions about web application development

What is the difference between a SaaS and a custom business application?

A SaaS (Software as a Service) is an online application, often multi-tenant, with a subscription model. A custom business application is developed specifically for a company's processes. At ark.swiss, we master both approaches and advise you on the most suitable one for your situation.

How much does it cost to develop a web application in Switzerland?

An MVP (minimum viable product) starts around CHF 10,000. A complete business application with authentication, dashboard and integrations ranges between CHF 20,000 and 50,000. A multi-tenant SaaS with automated billing can reach CHF 80,000 and above. We provide a detailed quote after a free consultation.

Can AI be integrated into a business application?

Yes, and it is one of our specialties. ark.flow uses multi-provider AI for accounting classification and OCR. We integrate artificial intelligence where it brings real value: automation of repetitive tasks, data extraction, intelligent recommendations.

How does SaaS maintenance work?

We have maintained our own products (ark.stock, ark.flow, ark.plan, Prezntly) since their launch. Maintenance includes security updates, 24/7 monitoring, automatic backups and functional evolution. We offer maintenance contracts tailored to each project.

What is a multi-tenant architecture?

A multi-tenant architecture allows multiple clients to use the same application instance while completely isolating their data. It is the standard model for modern SaaS. ark.stock operates on this principle: each client has their own dedicated space, configurations and billing via Stripe.

How long does it take to develop an MVP?

A functional MVP typically requires 2 to 4 months of development. This includes requirements analysis, UX design, development, testing and deployment. We favor an iterative approach: deliver a usable product quickly, then enrich it based on user feedback.

How do you secure my application data?

All our applications are hosted with Infomaniak in Switzerland, compliant with GDPR and the Swiss nFADP. We implement data encryption, secure authentication, automatic backups and continuous monitoring. Security is built in from the design phase, not added as an afterthought.
