What Our Clients Say

10 Reasons why Alphathena is the best Smartleaf alternative for financial advisors
1.Industry Recognition and Results
Alphathena is Winner of the 2023 Morningstar Fintech Showcase and a finalist for WealthManagement.com's 2023 and 2024 Artificial Intelligence and Direct Indexing awards. Smartleaf manages over $50 billion in assets, reinforcing its position in direct indexing and rebalancing.
2.Degree of Customization
Alphathena offers 40+ index customizations, including ESG and thematic investing, across 1,200+ ETFs and indexes, ensuring advisors can tailor portfolios to diverse client needs. Smartleaf provides limited customization options (typically 2-3), with a primary focus on ESG factors.
3.Household Support with Virtual Sleeves
Alphathena features built-in household support with virtual sleeves, enabling advisors to allocate securities within sleeves for precise rebalancing, transitioning, and tax-loss harvesting—eliminating the need for new accounts or cash movement. Smartleaf manages portfolios holistically but lacks designated sleeves for enhanced workflow control.
4.Multi-Scenario Transitions
Alphathena provides the most advanced transition module available, allowing advisors to analyze entire portfolios, model multiple scenarios, and optimize across all cases with detailed reporting. Smartleaf typically limits transitions to the security level, offering less flexibility in managing complex transitions.
5.Security and Account-Level Tax-Loss Harvesting
Alphathena performs tax-loss harvesting across entire households and identifies tax-efficient replacement securities at both security and account levels. Smartleaf provides automated year-round tax-loss harvesting but does not specify household-level optimization.
6.Advanced Optimization
Alphathena uses a sophisticated optimization engine that allows financial professionals to optimize index weights and allocations at scale, targeting multiple benchmarks and objectives. Smartleaf provides automated portfolio management but does not detail advanced optimization features.
7.API-First Scalability
Alphathena is built as an API-first platform, allowing seamless integration with inbound and outbound systems—critical for large institutions embedding direct indexing into their applications. Smartleaf lacks publicly available API capabilities.
8.Parallel and Batch Processing
Alphathena can rebalance and tax-loss harvest multiple accounts in real-time and offline, dramatically improving efficiency. Smartleaf focuses on automated rebalancing but does not specify parallel processing capabilities.
9.Integrated AI for Workflow Efficiency
Alphathena’s deep AI integration streamlines processes, enhancing usability and reducing manual workload. Smartleaf has no known AI integration.
10.White-Labeling Capabilities
Alphathena is the only platform that fully white-labels its web experience, allowing firms to customize the interface to match their brand. Smartleaf does not emphasize white-labeling as a core feature.
