Alex Malyshev’s SDK.finance is disrupting traditional fintech development by offering a flexible, API-driven platform that supports rapid deployment and AI-readiness, expanding into non-financial sectors as demand for embedded financial services accelerates.
Alex Malyshev has built his reputation on a simple but demanding idea: financial technology should reduce complexity, not add to it. As co-founder and chief executive of SDK.finance, he has positioned the company around a platform model that lets banks, payment providers and fintech firms launch and scale products without rebuilding core infrastructure each time. SDK.finance says its approach is designed for digital wallets, neobanks, payment ecosystems and embedded finance, with the company operating from Lithuania and serving clients across Europe, North America, the Middle East, Africa and Central Asia. According to the company, it also holds PCI DSS Level 1 and ISO 27001 credentials, and it was shortlisted in major industry awards in 2026.
The thinking behind that strategy came from experience rather than theory. Malyshev and his co-founder, Pavlo Sidelov, had already launched fintech ventures before deciding that the real opportunity lay not in building yet another financial product, but in building the infrastructure that products depend on. SDK.finance traces that decision back to 2013, when the pair recognised that account management, transaction processing, integrations and back-office operations were consuming too much time and capital for new entrants. Their answer was to create a modular, API-led platform that could be adapted to different business models, regulatory settings and growth plans. The company later said that the same approach had evolved into a wider infrastructure strategy, including a real-time general ledger intended to sit inside existing systems and provide audit-ready records.
That emphasis on reuse has been central to SDK.finance’s product philosophy. Rather than treating every deployment as a bespoke rebuild, the company argues that most financial institutions rely on the same foundation blocks: account services, transaction processing, reconciliation, fee management and compliance. Its pitch is to standardise that base layer while leaving room for differentiation in customer experience, workflows and market-specific features. In 2017, the company said it had expanded from zero to 246 APIs in a year, and that the move to an API-first architecture cut development costs sharply while reducing launch times to around three months. More recently, SDK.finance said it now offers more than 650 APIs and can be deployed either as software as a service or through
Malyshev has also argued that control over infrastructure is becoming more important as artificial intelligence reshapes software development. In the company’s telling, organisations that own and understand their core systems will be better placed to adapt as AI alters product design, automation and decision-making. He has said that financial services are becoming “more interconnected, regulations more demanding, customer expectations higher, and AI is beginning to reshape how software is developed.” SDK.finance’s response has been to focus on what it calls AI-ready foundations: structured data, event-driven architecture, deterministic transaction processing and full auditability. The company’s view is that AI should act as an intelligence layer, while the transaction platform remains the trusted execution layer beneath it.
That same logic now extends beyond traditional banks and fintech start-ups. In September 2026, SDK.finance said it was broadening its platform strategy to help retailers, marketplaces and telecom operators build native financial services into their own customer journeys. The company said those brands can use its infrastructure to embed payments, wallets and other financial workflows inside existing products, rather than launching separate financial operations from scratch. The expansion reflects a wider market trend: as more non-financial companies move into payments and embedded finance, demand is rising for modular systems that can support multiple products, currencies and regulatory regimes without increasing operational risk at the same pace.
For Malyshev, the commercial lesson is inseparable from the technical one. He has repeatedly described validation as the starting point for any serious product effort, saying founders should test assumptions early and be willing to change course if the market does not respond. That outlook, shaped by earlier ventures that stalled at prototype stage or failed to gain traction, has helped define SDK.finance’s long-term discipline. The company’s broader ambition is not simply to launch products, but to provide financial infrastructure that can evolve continuously, integrate cleanly with other systems and support future technologies without forcing customers into repeated reinvention. In a sector where trust, resilience and adaptability matter as much as speed, that may be the most important part of the strategy.
