Transforming Family Office Services

A Case Study on Three Horizons Capital’s Modular Platform for Wealth Managers

Executive Summary

This case study details how Three Horizons Capital has engaged with a leading European wealth manager to design and implement a modular, technology-driven family office platform. Facing a rapidly evolving landscape—marked by generational wealth transfer, rising client expectations, and increasing regulatory complexity—the client sought a scalable solution to deliver differentiated, future-proof family office services.

Three Horizons Capital’s practitioner-led team delivered a platform built on four core principles:

1. MVP-first development,

2. A variable cost model,

3. Off-the-shelf cloud-native tools, and

4. Client-controlled infrastructure.

This approach enabled rapid validation of new features, cost efficiency, and full regulatory alignment.

The platform’s eight integrated modules—ranging from digital onboarding and performance reporting to alternative asset management and ESG reporting—were deployed in phases, allowing the client to scale capabilities in line with business needs. As a result, wealth managers can achieve up to 70% reduction in onboarding time, 30–50% lower back-office costs, and significantly improved client engagement and retention.

This case study demonstrates how a modular, data-driven approach—grounded in industry best practice and real-world experience—can empower wealth managers to innovate, grow, and meet the evolving needs of family office clients.

Industry Landscape & Opportunity - The Family Office Evolution

The global family office sector is experiencing rapid growth, with assets under management projected to rise from $3.1 trillion in 2024 to $5.4 trillion by 2030 (Deloitte).

The Three Horizons Capital Approach

Three Horizons Capital’s platform is built on four core principles, each grounded in industry best practice and supported by data:

Minimum Viable Product First (MVP):  

We launch features as Minimum Viable Products to validate adoption before further investment.

• Consulting leaders such as McKinsey and Deloitte highlight MVP rollouts as a proven way to reduce risk and accelerate digital transformation in financial services.

• According to Deloitte, organizations using MVP approaches are 2.5x more likely to achieve successful digital outcomes.

Variable Cost Model: 

Clients pay only for what they use, aligning costs with business growth.

• PWC and EY identify usage-based pricing as a key driver of innovation and cost control for wealth managers.

• 67% of wealth management firms surveyed by EY in 2024 reported improved cost efficiency after adopting variable pricing models.

Off the Shelf Tools

We deploy established, cloud-native technologies to accelerate delivery and ensure compliance.

• Gartner and Accenture report that leveraging proven solutions reduces implementation time by up to 40% and lowers total cost of ownership by 30% for financial institutions.

Client-Controlled Stack:

All infrastructure is hosted in the client’s environment, ensuring data sovereignty and regulatory alignment.

• Regulators and industry surveys consistently cite client-controlled environments as essential for compliance  and risk management.

• In a 2024 EY survey, 78% of wealth managers ranked client-controlled infrastructure as “critical” for meeting privacy and regulatory standards.

This modular, client-first approach is recognized across the industry for reducing costs, improving adoption, and enabling rapid innovation.

Platform Modules: Innovation and Strategic Value

1. Client Onboarding & Document Digitization

By harnessing AI-powered document extraction and classification, our onboarding process transforms a traditionally manual, error-prone task into a seamless digital experience. This not only accelerates client onboarding—reducing processing times by up to 70%—but also ensures data privacy and compliance, a critical expectation in today’s regulatory environment. Human-in-the-loop quality assurance further guarantees accuracy, while clients benefit from faster, more transparent engagement from day one.

2. Reporting & Performance Attribution

Our platform delivers real-time, customizable reporting and granular performance attribution, empowering clients with actionable insights into their portfolios. Leveraging advanced analytics and cloud-native dashboards, we enable wealth managers to decompose returns by risk factors and asset classes, supporting more informed decision-making. Industry studies show that firms adopting automated, data-driven reporting see a 30–50% reduction in operational costs and a marked increase in client satisfaction.

3. CRM + Multi-Gen Planning

Recognizing the complexity of family structures and the importance of legacy, our CRM and multi-generational planning tools provide a holistic view of family governance, preferences, and succession plans. By integrating next-generation portals for surveys and education, we help wealth managers foster deeper, longer-lasting relationships—addressing the 70% of wealth transfers that fail due to lack of communication and trust, as highlighted in global family office research.

4. Cash Flow & Tax Aware Planning

Our scenario-based planning modules, powered by leading financial planning tools, enable dynamic modelling of cash flows and tax liabilities across jurisdictions. This empowers clients to optimize liquidity and minimize tax burdens, while automated compliance features reduce manual workload. According to EY, family offices with integrated cash flow and tax planning are 40% more likely to achieve their long-term financial objectives.

5. Alternative Asset Lifecycle Management

Managing private equity, real estate, and other alternatives is simplified through automated capital call tracking, distribution management, and commitment pacing dashboards. This end-to-end lifecycle management not only reduces administrative overhead but also supports portfolio diversification—a key driver of outperformance, with 89% of family offices increasing allocations to alternatives in recent years.

6. ESG & Impact Reporting

Our ESG module overlays third-party sustainability scores and aligns investments with the UN Sustainable Development Goals, providing transparent, actionable impact metrics. As 32% of European family offices plan to expand sustainable investments, our tools help clients meet both regulatory requirements and the rising expectations of next-generation stakeholders, while supporting robust, values-driven decision-making.

7. Back Office Automation

By automating general ledger entries, trade reconciliation, and reporting workflows, we free up valuable resources and reduce the risk of manual errors. This automation delivers measurable efficiency gains—clients have reported up to 50% reductions in back-office costs—while ensuring scalability as operations grow in complexity and volume.

8. Next-Gen Engagement Tools

To foster family cohesion and future readiness, our digital engagement suite offers learning hubs, milestone tracking, and secure content sharing. These tools not only support education and governance but also strengthen intergenerational bonds, addressing a critical need as family offices prepare for the largest wealth transfer in history.
