About Portify

Over 90% of new jobs are 'contingent work'. Think gig-economy, zero-hour contracts, and hourly pay often across multiple employers. Workers often choose this work to maximise their flexibility.

Portify offers a simple suite of products that help these workers maximise take home pay, to make sure this freedom comes with financial security. Our vision is to build a world where everyone can pursue their dreams without economic concerns.

Since our founding in May 2017, Portify has raised over £6m and helped tens of thousands of workers with the thing that matters to them most: money.
