How much does custom software development cost?

Projects at Tallium typically start from $50,000 for full-cycle product development. Packaged offerings start lower: a Product Concept sprint is $4,950 and a custom AI assistant is $7,950. Most client engagements range from $50,000 to $200,000+, depending on scope and team size. Tallium's rates are up to 50% lower than comparable in-house development and 20-30% below other mature outsourcing companies.

How long does a custom software project take?

Timelines depend on project scope. A product concept and development strategy is ready in 2 weeks. A clickable prototype takes 4-6 weeks. A full MVP is typically delivered in 2-4 months. A core engineering team can be assembled in 1-2 weeks; custom profiles take 3-4 weeks to hire. Dedicated team and ongoing development engagements are open-ended and scale with the client's roadmap.

What is the minimum project size Tallium takes on?

The smallest packaged offering is a Product Concept sprint at $4,950, which delivers a validated product concept, architecture, and development roadmap in 2 weeks. For full-cycle development, the recommended starting budget is $50,000-$100,000, which typically covers an MVP. Tallium does not take on isolated ad-hoc tasks; all engagements are structured around clear business goals and a defined scope.

Does Tallium work with companies outside the Netherlands?

Yes, the majority of Tallium's clients are outside the Netherlands. Active and past clients are based across Europe (UK, Sweden, Switzerland, Germany, Ukraine), North America (US, Canada), Australia, and Israel. Tallium has offices in Ukraine, Poland, Sweden, the Netherlands, and Canada. All project communication is conducted in English.

What technologies does Tallium use?

Tallium covers the full modern product stack. Frontend: React, Vue, Angular. Mobile: React Native, Flutter, iOS (Swift), Android (Kotlin). Backend: Node.js, Python, PHP (Laravel), Java, .NET. Infrastructure: AWS, GCP, Azure, Docker, Kubernetes. AI/ML: OpenAI, LangChain, TensorFlow, PyTorch. The specific stack is always chosen based on the client's existing systems and product requirements. Tallium does not impose a preferred stack.

The Challenge

For years, the company relied on a financial system that included a mobile app as a supporting feature. When Arcapita decided to switch to a new system, they discovered it didn’t offer a mobile application at all.

For a company working with sophisticated investors, this created operational and strategic risk. At the same time, Arcapita did not want to become dependent on third-party mobile solutions. So they chose to build a custom mobile app and reached out to us.

How we built Arcapita

How we helped a premier Islamic asset management firm build a secure platform for managing investments that combines mobile, web, admin applications, and seamless Salesforce and KYC integrations.

Building a unified investment management system

The platform we developed covers a mobile app, a web application, and an internal administrative panel.

Mobile app

We built the mobile app using Kotlin Multiplatform, reusing core business logic across iOS and Android to speed up development while keeping a native look and feel on each platform.

Admin panel

The admin panel is developed using a standardized frontend template and connected to backend services. It gives Arcapita control over content and system management.

Web platform

Since the platform relies on document-heavy workflows and structured financial data, we chose ReactJS for the web application to deliver a responsive interface for KYC files, investment reports, and more.

Shaping the cross-platform experience

The design process began with prototypes, where we agreed on user flows, visual hierarchy, and interface components. We also created high-fidelity mockups to test usability before implementation.

As part of the redesign, we also addressed inconsistencies in content rendering between web and mobile. The mobile app initially used web views to display admin panel content, which caused formatting issues. We replaced these with native Kotlin UI components and simplified the editor in the admin panel, reducing styling options. This brought visual consistency and reinforced the platform’s technical foundation.

Mapping the investor journey

To ensure alignment from day one, our Business Analyst worked closely with Arcapita’s stakeholders to map the complete investor lifecycle.

Through workshops and discovery sessions, we defined two core user roles: investors and managers. Here’s what the investor journey looks like:

Registration

KYC Registration

Platform access

Investment

Portfolio ownership

#01

Registration

Fill in the registration form.

#02

KYC Registration

Upload required documents and complete identity checks.

#03

Platform access

Get full access to the system.

#04

Investment

Invest in assets and sign the required documents.

#05

Portfolio ownership

Manage your investment portfolio.

Managers oversee investor portfolios and maintain direct communication, since investments of this scale are typically finalized offline. For the same reason, we did not integrate any payment systems into the platform.

Implementing a secure and compliant infrastructure

Security is a core requirement for an investment management platform, so we had to build an architecture that meets strict compliance and regulatory standards.

Reliable biometric authentication

When implementing iOS biometric authentication, we discovered a mismatch between the mobile app and the backend. We traced the root cause to outdated backend encryption, aligned both sides to current standards, and stabilized the verification process.

Custom KYC camera implementation

The native iOS camera functionality did not provide the level of control required to meet KYC document capture standards. That’s why we implemented a customized camera solution with precise control over framing, capture behavior, and image quality.

Secure document handling

To meet file security requirements and protect sensitive investor data, we implemented a two-stage Azure Blob Storage architecture. Uploaded documents are first stored in a quarantine container, scanned for viruses, and only then transferred to secure storage.

Technology stack

The core challenge was integrating third-party systems—Salesforce, Twilio, SendGrid, and Faceki KYC—while resolving real issues like API edge cases and encryption mismatches. This required a custom KYC camera and a secure, two-stage Azure Blob Storage pipeline to protect sensitive investor data.
