From integration partner to ecosystem steward

Client:Mollie
Partnered:2018
Industry:FinTech / Payments

When Mollie was in its earlier growth phase, they made a strategic decision: to outsource their integrations so their internal engineering teams could stay laser-focused on their core product. What began with PHP integration work quickly evolved into a long-term, multi-dimensional collaboration spanning architecture, strategy, ecosystem leadership, and developer marketing.

Key Contributions

Core Integration Development

  • Maintaining and evolving Mollie's most widely used PHP libraries, including mollie-api-php, laravel-mollie, and laravel-cashier-mollie
  • Maintaining oauth2-mollie-php, which underpins Mollie's Marketplace features

Ecosystem Stewardship

Beyond PHP, we support third-party developers building Mollie integrations across ecosystems like Node.js, WooCommerce, and Shopware. We assess technical architecture, review community contributions, and help ensure a high-quality, well-aligned ecosystem.

Community & Developer Marketing

  • Representing Mollie in PHP and Laravel communities
  • Leading launch strategies for Laravel integrations
  • Facilitating relationships with framework maintainers

Technical Leadership

  • Consulting on architecture, API design, and developer experience
  • Supporting sales teams with technical evaluations
  • Maintaining security and code quality standards

Sandorian is our one-stop shop specialist for many different integrations and packages. Their expertise, creativity and clear communication make them an incredible partner of Mollie.

Outcome

By outsourcing their integrations to Sandorian, Mollie was able to double down on its core product while still delivering an outstanding developer experience across multiple ecosystems.

This depth and consistency of contribution led Mollie to award us their first-ever officially preferred integration partner status, recognizing our unique role at the intersection of code, community, and collaboration.
