Southeast Asia’s fintech scene has grown far beyond the early days of e-wallets and BNPL. Today, the sector has matured into a sophisticated ecosystem spanning personal finance, digital investing and cross-border payment solutions. Fuelled by a growing middle class, rapid digital adoption and supportive regulatory frameworks, fintech is no longer just about convenience; it is becoming the region’s engine for financial inclusion, wealth building and SME empowerment.

This momentum is also reflected in investor confidence; ASEAN fintech funding has surged more than tenfold since 2015, with over 60% of capital going to early-stage startups through 2024. Backed by this influx of funding, a new wave of innovators is tackling structural gaps in the financial system: lowering the cost of international transfers, opening up investment opportunities to first-time investors giving businesses faster access to global markets. These startups are redefining how Southeast Asia saves, spends and invests.

Below are five that are leading the way in the Southeast Asia fintech scene.

Tazapay (Singapore): B2B cross-border payments made simple

In a region where SMEs often struggle with the complexity and cost of cross-border transactions, Singapore-based Tazapay is making international B2B payments faster, safer and more transparent. The platform supports over 173 markets for collections and 85 markets for payouts, offering escrow services and advanced transaction monitoring to reduce fraud risk.

Recent partnerships with global players have expanded Tazapay’s reach, enabling SMEs to participate more competitively in global trade. As regulators across Southeast Asia push for more secure payment infrastructures, Tazapay’s compliance-focused approach gives it an edge in winning trust from both merchants and financial institutions.

StashAway (Malaysia/Singapore): Pioneering robo-advisory in the region

Launched in 2016, StashAway has become a household name in digital wealth management across Malaysia, Singapore and beyond. Its data-driven investment algorithms allow users to create personalised portfolios with low fees, making professional investment management accessible to everyday consumers.

The platform has expanded into thematic portfolios covering sectors like technology and clean energy while integrating cash management features that rival traditional banks’ offerings. Backed by strong regulatory credentials in multiple markets, StashAway continues to draw investors looking for a blend of automation, diversification and long-term wealth-building strategies.

Flip (Indonesia): Cutting the cost of money transfers

Flip began by tackling a distinctly Indonesian challenge: high domestic bank transfer fees and has since grown into one of the country’s most trusted payment platforms, serving over 10 million users and processing more than US $12 billion in annual transactions. Its appeal lies in making transfers fast, affordable, and transparent, a combination that has won it both mass consumer adoption and the trust of hundreds of companies for payroll, supplier payments, and refunds. Investor confidence has followed suit, with total funding surpassing US $100 million after back-to-back Series B rounds led by Tencent, Block, and other global players.

In February 2025, Flip strengthened its international capabilities through a strategic partnership with Wise Platform, integrating the service into Flip Globe. This has delivered striking results: transfers to destinations like the Philippines now take just 20 seconds, compared to the previous 8.5 hours; failure rates have dropped to 1–2% on key routes; and customer support tickets fell by 40% overall and 60% on Malaysia routes. The partnership has also driven a 5–10% uplift in transaction volumes, while maintaining competitive fees for millions of Indonesians, including migrant workers sending remittances home.

The timing could not be better. Indonesia’s outbound remittance market is projected to hit US $5.63 billion by 2028, reflecting rising cross-border financial flows as Southeast Asia’s economies grow more interconnected. By combining scale, speed, and affordability, Flip is positioning itself as a critical bridge between local banking networks and global remittance corridors—reshaping how money moves in and out of one of the region’s most dynamic markets.

Pluang (Indonesia): Micro-investments for the mobile-first generation

With millions of Gen Z and millennial users in Indonesia, Pluang has tapped into the appetite for accessible investing. The platform lets users start with as little as a few thousand rupiah, offering fractional investments across asset classes, stocks, gold, cryptocurrencies and more.

By integrating with popular “super apps” like Gojek and Tokopedia, Pluang meets young investors where they already spend time online. This embedded approach not only drives adoption but also normalises the idea of investing as part of everyday financial habits.

Ajaib (Indonesia): Fast-tracking digital stock market participation

In just a few years, Ajaib has become one of Indonesia’s fastest-growing investment platforms, thanks to its commission-free trading model and simplified onboarding process. It has been especially successful in attracting first-time investors, offering educational resources and tools designed to build confidence in the capital markets.

By lowering the barriers to entry, Ajaib is helping broaden retail participation in Indonesia’s stock market, a trend with long-term implications for market depth and stability. Its continued growth has also attracted significant investor backing, signalling confidence in the scalability of digital-first brokerage models in Southeast Asia.

Beyond the apps: The rise of embedded finance

The success of these fintech startups reflects a broader shift towards embedded finance, where financial services are integrated directly into non-financial platforms. This trend is blurring the lines between banking and investing, making it easier for consumers to manage money without ever stepping into a bank branch.

For traditional banks, this could be a double-edged sword: partnerships with fintechs can extend reach, but it also means ceding some customer relationships to more agile digital players. Over the next three to five years, expect more collaborations between incumbents and fintechs, as well as regulatory frameworks that balance innovation with consumer protection.

Southeast Asia’s fintech evolution is far from over, but with these five startups leading the charge, the way the region saves and spends is already being rewritten.
