GeoIP Services Ensure Fomo’s Customers Don’t Miss Out on Sales

Every year, more than a billion consumers shop on e-commerce websites. And in 2016, a new startup called Fomo set out to help merchants reach that audience. To do that, Fomo first needed to find a service partner with expertise in geolocation. They chose MaxMind. “We’re a relatively new company, but our growth has been phenomenal since we added MaxMind’s GeoIP2 Precision services,” said Fomo’s co-founder Ryan Kulp.

Where in the World?


Santa had a problem, and the problem was kids. Not that he didn’t love the children – far from it, their happiness was why he did what he did after all – but now there were more than ever of them. World population had grown to the point where there were 2.2 billion children that potentially wanted a gift, and that was a lot of mince pies to get through in one night!

To ensure that he’d have time to make all the deliveries, he’d taken the unprecedented step of installing agents in homes around the world – elves that sat on shelves – who were able to report on any problem, from waking children to adverse weather conditions, that might slow him down. Traditionally, a Shelf Elf would report by flying home each night leading up to Christmas, but on the big night itself the elf would have to report back in real time. Luckily for Santa, so many houses had internet connections that the Elf could use to report issues via a simple web form the Wise Old Elf had set up on the North Pole extranet. Continue reading

Building Your Own MMDB Database for Fun and Profit

If you use a GeoIP database, you’re probably familiar with MaxMind’s MMDB format.

At MaxMind, we created the MMDB format because we needed a format that was very fast and highly portable. MMDB comes with supported readers in many languages. In this blog post, we’ll create an MMDB file which contains an access list of IP addresses. This kind of database could be used when allowing access to a VPN or a hosted application.

Tools You’ll Need

The code samples I include here use the Perl MMDB database writer and the Perl MMDB database reader. You’ll need to use Perl to write your own MMDB files, but you can read the files with the officially supported .NET, PHP, Java and Python readers in addition to unsupported third party MMDB readers. Many are listed on the GeoIP2 download page. So, as far as deployments go, you’re not constrained to any one language when you want to read from the database.

Following Along

Use our GitHub repository to follow along with the actual scripts. Fire up a pre-configured Vagrant VM or just install the required modules manually.

MaxMind Announces Corporate Giving Program

MaxMind is pleased to announce our corporate giving program – we plan to give away over 50% of our profits to charity.

Since its inception, MaxMind has focused on creating value for our customers, especially where the ratio of value to effort is high. It is exciting how technology enables us to write code once and deploy it to thousands of customers to solve problems. For marketing, we focus on strategies that have high impact per dollar invested, including detailed, transparent information about our products on our website and our freemium model for geolocation databases.

Similarly, with charitable giving, we look for opportunities to apply research to find how our funding can have high impact per dollar invested. Sometimes the most cost-effective program can be surprising. For example, according to MIT’s Abdul Latif Jameel Poverty Action Lab, deworming may be one of the most effective ways to increase student participation in school.

The for-profit space seems more and more crowded with great companies pursuing great ideas. There appears to be no shortage of angel and venture capital for technology startups, and competition is intense. On the other hand, the non-profit space appears a lot less crowded, as there are fewer funders pursuing innovative solutions.

We would like to thank our customers for making this possible!
