Investment App Development

Investment app development is the process of building software platforms that handle real-time trading, portfolio tracking, robo-advisory, fractional ownership, and wealth management. These platforms require financial-grade architecture: low-latency data feeds, encrypted transaction flows, audit logging, and compliance with regulations such as FCA, SEC, and MiFID II.

Scrums.com builds investment apps for FinTech companies, banks, and asset management firms. Our dedicated engineering teams deploy in under 21 days and embed directly into your product organisation, giving you the mobile and backend engineering capacity to ship without a 6-month hiring cycle.

Investment App Development for FinTech and Banking Teams

The investment sector is one of the most demanding environments for app development. Every engineering decision carries regulatory weight: transaction logging must be tamper-proof, data storage must meet jurisdiction-specific requirements, and user authentication must satisfy multi-factor standards set by financial regulators.

Three areas where investment app development most frequently requires specialist engineering capacity:

• Real-time data integration: Connecting to market data providers and exchange APIs, and maintaining low-latency update cycles at scale, requires careful backend architecture that general-purpose teams consistently underestimate.
• Regulatory compliance: Apps serving UK or EU markets must satisfy FCA authorisation requirements and MiFID II transaction reporting obligations. US-facing platforms operate under SEC and FINRA oversight. Compliance is not a post-launch addition: it must be designed in from the first sprint.
• Portfolio calculation engines: Real-time profit and loss, risk-adjusted return calculations, and tax-lot accounting require backend services purpose-built for financial computation, not adapted from standard SaaS patterns.

In practice, this means compliance architecture has to be designed in from day one. Working with JamiiPesa, a Kenyan FinTech, Scrums.com built a blockchain-powered investment platform handling fixed-income products in KES and USD, with KYC and AML via Smile Identity and immutable transaction logging via Kaleido. A phased delivery strategy enabled early market entry while managing regulatory constraints, with 100% sprint completion during key delivery cycles. That is the kind of financial domain knowledge FinTech companies and banking and financial services organisations need from an engineering partner before the first sprint begins.

1. Real-time market data architecture: Integration with financial data providers and exchange APIs, with event-driven backend design to handle tick-by-tick updates without degrading user experience or introducing latency at scale.
2. Secure transaction processing: End-to-end encryption, PCI-DSS-aligned payment flows, multi-factor authentication, and immutable transaction logs that satisfy audit and regulatory requirements across jurisdictions.
3. Cross-platform mobile delivery: Native iOS and Android apps or cross-platform builds using React Native or Flutter, sized to your user acquisition strategy and long-term maintenance budget.
4. Compliance-aware data storage: Jurisdiction-specific data residency, GDPR-compliant user data handling, and retention policies aligned with SEC, FCA, or MiFID II requirements from day one.
5. Dedicated team deployment: Scrums.com engineering teams deploy in under 21 days. Engineers work exclusively on your product with no ramp-up delays, operating as a direct extension of your engineering organisation.

Tech Stacks for Investment App Development

Investment app development requires a stack that prioritises latency, security, and auditability. Our teams work across the following:

• Frontend: React Native and Flutter for cross-platform builds; Swift and Kotlin for native iOS and Android where performance or platform-specific requirements demand it.
• Backend: Node.js and Go for high-throughput transaction services; Python for quantitative analytics and machine learning-driven portfolio features.
• Databases: PostgreSQL for transactional data with strict consistency requirements; Redis for real-time caching; TimescaleDB for time-series market data storage.
• Market data integration: Bloomberg B-PIPE, Refinitiv Eikon, Alpha Vantage, and direct exchange APIs depending on asset class and target geography.
• Compliance and security: OAuth 2.0, OpenID Connect, hardware security module integration for key management, and SOC 2-aligned logging practices for audit-ready environments.
• Cloud infrastructure: AWS and Google Cloud for scalability and geographic data residency; infrastructure-as-code for reproducible, auditable deployment pipelines.

Frequently Asked Questions: Investment App Development

How long does it take to build an investment app?

A production-ready investment app typically takes 4 to 9 months from initial design to launch, depending on feature scope and regulatory requirements. An MVP with core trading or portfolio tracking can be delivered in 8 to 12 weeks with a dedicated team. Scrums.com deploys teams in under 21 days, so engineering work starts immediately after scoping is complete.

What does investment app development cost?

Costs vary by scope. A portfolio tracking MVP can range from $80,000 to $150,000. A full trading platform with real-time data feeds, compliance architecture, and multi-asset support typically ranges from $300,000 to over $1 million. Scrums.com uses usage-based pricing: you pay for active engineering time with no bench fees or lock-in contracts.

What regulations apply to investment apps?

Regulation depends on geography and asset class. US platforms typically operate under SEC and FINRA oversight. UK and EU platforms fall under FCA authorisation and MiFID II. Compliance covers transaction reporting, data residency, KYC and AML processes, and user disclosures. These must be built into the architecture from the start, not retrofitted after launch.

Can Scrums.com build both the mobile app and the backend?

Yes. Scrums.com provides full-stack investment app development: mobile (iOS, Android, cross-platform), backend services, market data API integrations, and cloud infrastructure. One dedicated team covers the full delivery scope with no subcontracted handoffs between vendors and no coordination overhead across separate teams.

What is the difference between a robo-advisor and a trading app?

A robo-advisor automates portfolio construction and rebalancing based on user goals and risk tolerance, with no direct user trades required. A trading app gives users real-time market access to buy and sell assets themselves. Engineering requirements differ significantly: trading apps need low-latency order management systems; robo-advisors need portfolio calculation engines and automated rebalancing logic.
