Sea’s MariBank Targets Singapore SMEs With Zero-Fee Accounts, Plans Regional Digital Banking Group

One in three Singaporean business owners still use their personal bank accounts for company banking, according to a survey from MariBank, the digital bank owned by Southeast Asian tech giant Sea. The practice, driven by a desire to escape high transaction fees at traditional institutions, creates tax and legal headaches when owners try to separate legitimate profit from personal spending at tax time. Natalia Goh, MariBank’s CEO, told Fortune that while local and international banks maintain a strong presence in the city-state, certain banking needs remain underserved.

The problem isn't unique to Singapore. Across ASEAN, a young, tech-savvy population is driving rapid adoption of digital banking services, with more than 25 digital banks now operating in the region, according to HSBC analysis. Fewer than half of these are backed by traditional financial institutions. The rest originate from fintechs, e-commerce platforms, and super-app consortia, reflecting demand for alternatives to legacy banking.

MariBank’s solution is a business account with zero transaction fees and a single app that lets customers toggle between personal and business banking. The product targets the friction that pushes small business owners toward personal accounts, which are not designed for commercial use and create compliance risks. Goh frames the offering as filling a gap between what established banks provide and what micro and small enterprises actually need.

The broader ambition goes beyond one product in one market. MariBank is positioning itself to build what Fortune describes as a regional digital banking group out of Singapore. The company launched in 2023 as a wholly owned subsidiary of Sea, which ranks number 12 on the Fortune Southeast Asia 500 and is the parent of e-commerce platform Shopee. That ecosystem connection provides a built-in customer base and data advantages that pure-play neobanks lack.

The regulatory environment across Southeast Asia has been unusually welcoming to digital bank entrants. The Monetary Authority of Singapore awarded four digital banking licenses in 2020, with MariBank and GXS receiving the two full digital bank licenses that allow them to serve retail customers. Malaysia’s central bank followed with plans for up to five new online bank licenses in December 2019, and the Philippine central bank published its digital banking framework in September 2020, according to Pismo.

Demand-side factors are equally important. An Atos survey cited by HSBC found that Southeast Asian customers were the most receptive in the Asia Pacific region to banking services offered by fintechs and challenger entrants. Regional super apps like Grab, GoTo, and MoMo are reshaping consumer expectations about how financial services should integrate with daily life. Statista data points to millennials and Gen Z as the primary adopters, drawn to mobile-first interfaces and lower fees that digital banks can offer because they avoid the overhead of physical branch networks.

Despite the licensing excitement, the results have been mixed. The Diplomat reports that with several years of data now available, digital banking in Southeast Asia has not developed quite as expected. The Philippines, Singapore, Indonesia, and Thailand show a great deal of divergence in outcomes. Early optimism from the 2020 licensing rounds has collided with the operational reality of building profitable digital banking businesses in markets where incumbents still hold significant trust and distribution advantages.

Backbase, a banking platform vendor, highlights one success story: a leading Southeast Asian bank that used its Engagement Banking Platform to overhaul digital business banking achieved a 40 percent improvement in process efficiency and 246 percent growth in digital engagement. The case study suggests that traditional banks are not standing still, and they are investing in the same omnichannel capabilities that neobanks use as their primary selling point. MariBank’s zero-fee strategy is one way to compete against both incumbent modernization and other digital challengers.

For Singapore SME owners, Mari's entry means a concrete alternative to the status quo. The zero transaction fee model directly addresses the cost complaint that drives business owners to misuse personal accounts. The single-app toggle between personal and business banking solves a user experience problem that traditional banks rarely address, since retail and business banking typically sit in separate organizational silos with separate apps and login credentials.

The tax and legal implications are equally significant. Using personal accounts for business transactions creates audit risk and makes bookkeeping unnecessarily complex. By offering a properly structured business account at no transaction cost, Mari removes the financial incentive for bad banking hygiene. Whether small business owners trust a digital-only bank with their company finances remains an open question, but the product design targets the precise pain point that the market research identified.

MariBank's parentage gives it capabilities that standalone digital banks cannot easily replicate. Sea operates Shopee, one of Southeast Asia's dominant e-commerce platforms, along with gaming and fintech businesses. The ecosystem provides transaction data, customer acquisition channels, and a brand that millions of regional consumers already recognize. A Shopee merchant who already uses Sea's payment infrastructure is a natural candidate for a Mari business account.

This is the same playbook that Chinese tech giants Alibaba and Tencent used to build Ant Group and WeBank, respectively. The Diplomat notes that the 2020 licensing round seemed like it might open an exciting new chapter in digital finance, and the ecosystem model is the reason. Standalone neobanks must spend heavily on customer acquisition. Ecosystem banks can offer financial services as a natural extension of platforms where users already spend their time and money.

Mari's regional ambitions will face regulatory complexity as it expands beyond Singapore. Each ASEAN market has its own licensing regime, capital requirements, and consumer protection rules. The Philippines, Indonesia, Malaysia, and Thailand all have digital banking frameworks, but they differ in their openness to foreign-controlled digital banks. Sea's existing presence in many of these markets through Shopee gives it a foothold, but banking is a different regulatory animal than e-commerce.

The competitive landscape will also intensify. Traditional banks are investing in their own digital transformation, as the Backbase case study illustrates. Other digital license holders like GXS, backed by Grab and Singtel, are pursuing similar strategies. The question is whether Mari's zero-fee model can sustain profitability long enough to build a lending book and generate net interest income, which Statista identifies as the primary growth metric for the region's digital banks. The early signs suggest a market that is expanding fast but rewarding only the operators that can convert user growth into sustainable economics.
