I posted Open Exchange Rates[0] as a Show HN 1,534 days ago. It had just moved away from publishing free currency data into a GitHub repository, to its own website. In fact, they had just asked me politely to take it down due to the high traffic.<p>Open Exchange Rates was initially a portfolio piece (a labour of love that I hoped would land me a job at Stripe!) I launched it as an adjunct to money.js[1], a minimal JavaScript currency conversion library. The latter is still popular, but Open Exchange Rates has since organically grown on its own merits into a community of over 50,000 developers, with hundreds of tutorials and open source integrations. It's my full-time job, and there are seven of us on board.<p>We've since grown to be the industry-leader in our niche, loved and relied upon by Booking.com, SkyScanner, Etsy, KickStarter, WordPress.com, BrainTree, Coursera, Fab.com, Wego, Lonely Planet, Stripe, SoundHound, Vice.com - and thousands more of the world's most trafficked websites and brands.<p>This week, over four years later, I've just returned to Hong Kong - the project's birthplace - to work with our team here. We're about to switch on a platform that will open up true real-time data for our clients in high-risk financial environments, and allow us to scale to the next 500,000 clients and beyond.<p>I never liked where the industry is heading - towards competitive, closed, stingy business - so we've chosen to move further towards transparency, sharing and collaboration. The next steps in our journey are where we open more and more to our community and marketplace, meanwhile tailoring our higher-ticket service to those who need it.<p>(Thanks for posting this Ask HN!)<p>[0] <a href="https://openexchangerates.org" rel="nofollow">https://openexchangerates.org</a><p>[1] <a href="https://github.com/openexchangerates/money.js" rel="nofollow">https://github.com/openexchangerates/money.js</a>
