Hi, we are Tangelo.

We help you take full control of your corporate reporting process.

Our story

Our story

Since 2010, we’ve been dedicated to transforming the way companies around the world create and deliver their corporate reports—from annual and sustainability reports to impact statements and beyond.

For years, corporate reporting was a fragmented and frustrating process. Teams across finance, sustainability, and communications worked in silos, juggling spreadsheets, documents, and design files. Version control was a nightmare. Formatting edits came in at the eleventh hour. And with every new stakeholder or regulatory change, the pressure mounted.

It wasn’t just inefficient—it was unsustainable.

We believed there had to be a better way. Not just a tool, but a smarter, more connected way of working. That’s why we built Tangelo: a single-source, multi-channel platform with automated typesetting—eliminating the desktop publishing bottleneck and giving organizations the structure, flexibility, and efficiency they need to produce corporate reports with confidence.

The result? A reporting process that empowers teams to work faster, smarter, and more in sync—delivering reports that are accurate, on-brand, and always on time, with less stress.

We call this: Corporate reporting, transformed.

Corporate Reporting in the Digital Era

Built for native digital reporting

Corporate reporting is evolving, with electronic (digital) reporting in XBRL format, such as ESEF and UKSEF, introducing structured data requirements in many regions. While traditional tools struggle to adapt, Tangelo was built natively for digital reporting, seamlessly handling these formats without workarounds.

Sustainabilty & ESG reporting

At the same time, sustainability and ESG reporting have expanded the audience for corporate reports, increasing expectations for interactive, digital-first online reports that engage investors, employees, customers, suppliers, and civil society. With its single-source, multi-channel approach, Tangelo has long supported this shift, enabling companies to publish reports across formats with ease.
