Visual TL;DR
The company’s API-first platform is designed to enable banks, fintechs, and other institutions to launch and scale financial products. This includes core components like a general ledger, databases, and software for cards, loans, and bank accounts. A workflow builder with a marketplace for integrations is also part of the offering.
The investment comes as legacy systems create significant infrastructure debt, hindering AI adoption. Intelligent agents require clean APIs and accessible data, which older core banking systems often lack.
Stitch is capitalizing on a unique opportunity in the Middle East, where a regional push to diversify economies beyond oil is fueling rapid growth in financial services. The industry is expanding at 10% year-over-year, with Saudi Arabia alone anticipating hundreds of new financial institutions needing core banking software.
The platform has seen substantial traction, processing over $5 billion in transactions in the last six months. Customer numbers grew tenfold in 2025, while revenue increased twentyfold. Stitch’s reach extends beyond the GCC to Africa and Southeast Asia.
Regional clients like Lulu Exchange and Raya Financing have reportedly launched products up to 80% faster using Stitch’s flexible infrastructure. This modernization is seen as crucial for financial institutions looking to embrace AI transformation, enabling features like AI-powered customer support and automated loan origination.
Mohamed, Stitch’s founder, possesses a rare blend of industry relationships, sales acumen, and determination. He has assembled a team with experience from major players like FIS and Barclays. This round marks a16z’s first investment in Saudi Arabia.
The firm believes Stitch represents the next generation of global fintech infrastructure, built for a market with strong tailwinds and led by a founder knowledgeable in both technology and regulation. By providing a modern system of record, Stitch aims to unlock broader AI capabilities for financial services.
