Top Banking and Fintech Software Companies in Bangladesh (2026)
Published by Kaz Software. Last reviewed November 11, 2026.
Banking software is the part of the Bangladesh market where the right vendor matters most and the wrong one costs most. A core banking system, a card platform and a microfinance ledger are different products from different specialists. This guide picks six companies from our Top 25 Software Companies in Bangladesh (2026 Guide) that work in banking and fintech, says what each is best at, and sets out what Bangladesh Bank's 2026 cybersecurity framework means when you choose a vendor.
Editor's note: Kaz Software publishes this guide and lists itself where its work fits. The order follows our Top 25 Software Companies in Bangladesh (2026 Guide) and is editorial judgment, not a scored or audited ranking. Figures marked “self-reported” come from each company's own website and have not been independently verified.

What the 2026 rules mean for choosing a vendor
Bangladesh Bank issued its Cybersecurity Framework, Version 1.0 (2026) on 29 March 2026, according to The Business Standard. Scheduled banks, finance companies, mobile financial service providers, payment service providers and payment system operators must implement it fully by 31 December 2026. It is organised around six functions (identify, protect, detect, respond, recover and reporting), and it covers third-party and outsourcing risk and security across the system development lifecycle.
The framework applies to the institutions, not to their vendors. In practice, though, an institution that must manage outsourcing risk will ask its software supplier how it builds, tests and secures code. A vendor that can answer in writing makes that job easier. This is our reading, not legal advice.
Data law also matters. The government gazetted the Personal Data Protection Ordinance, 2025 on 6 November 2025, as The Business Standard reported on 9 November 2025. It treats financial, health, genetic and biometric information as sensitive data with enhanced protection. The Daily Star's summary of the cabinet-approved draft in October 2025 said that some sections would take effect 18 months after gazette publication, that breaches must be reported to the new data authority, and that transfers of personal data abroad need equivalent protection in the destination. Check the gazetted text with a lawyer before you rely on any of this.
The six companies
Kaz Software
Kaz lists fintech among the sectors it has built for (self-reported) and staffs full project teams of engineers, QA, designers and project managers. It is not a core banking vendor. If you need to replace a core banking system, start with LeadSoft. If you need custom digital products around your core, such as customer apps, internal tools or AI features, we would like to talk.
SELISE Digital Platforms
SELISE was founded in Zurich in 2011 and runs its main engineering hub in Dhaka. It builds and operates enterprise platforms for retail, insurance and banking, manufacturing and telecom clients, and reports ISO 27001 and ISO 9001 certification and 700+ staff across eight locations. BASIS named it a top-10 IT/ITES exporter for FY2024-25.
Brain Station 23
Brain Station 23, founded in 2006, works across fintech, telecom, pharma and retail, and reports 900+ staff plus ISO 27001 and CMMI Level 3 certification (self-reported). BASIS named it a top-10 IT/ITES exporter for FY2024-25. It fits large programmes that need many engineers across several technologies at once.
LeadSoft Bangladesh
LeadSoft, founded in 1999, is a subsidiary of LEADS Corporation and developed BankUltimus, a core banking system for retail, SME and corporate banking. According to The Financial Express (August 2026), 13 Bangladeshi banks run LEADS' core banking software, and Western Group bought LEADS in July 2024. LeadSoft also takes outsourced development work, including for Japanese clients (self-reported).
Southtech Group
Southtech, founded in 1996, sells Ascend Financials for microfinance institutions, plus HR, retail and POS, ERP, VAT and insurance systems. It reports offices in Bhutan and Myanmar and CMMI Level 5 certification (self-reported). It suits microfinance institutions, banks and retailers in South Asia.
KONA Software Lab
KONA Software Lab began in 2012 as the Dhaka R&D centre of South Korea's KONA I and now builds payment technology: card operating systems, card personalisation, digital wallets and e-KYC. The Daily Star reported in August 2025 that it launched a locally built card personalisation system for Islami Bank Bangladesh. It reports Visa Ready and FIPS 140-2 status, and clients including Dutch-Bangla Bank's NexusPay and Nagad (self-reported).

What to ask before you sign
Cybersecurity framework: ask which parts of Bangladesh Bank's 2026 framework the vendor's practices support, and how it can show that in writing.
Data: ask where data and backups are stored, who can reach production, how access is logged, and how it is removed when someone leaves the project.
Certificates: ask for the ISO 27001 certificate number and issuing body, and look up any CMMI appraisal in the CMMI Institute's published results. Appraisals expire, so check the date.
Payments: for card or wallet work, ask which scheme or standards certifications the product has actually completed, and ask to see the documents.
References: call two banks or financial institutions with a similar scope.
Pilot: run a paid pilot of two to four weeks on one module, in your own repository, before you commit.
