Today, we are excited to announce that Thoma Bravo has acquired a majority stake in Mailgun, with Turn/River retaining a minority position. We’re thrilled about what this strategic growth investment means for our customers and the platform in general.

Where we’ve been

In 2010, when we were first starting Mailgun, we saw developers struggle to integrate email into their applications. The process involved a lot of time, a lot of code, and a lot of infrastructure maintenance. Our team set out to develop an easier, more reliable way to send, receive, and track emails via API, and that’s precisely what we’ve done. 

Now, over 150,000 companies trust Mailgun to deliver their transactional and marketing emails to the inbox. Our workforce has quadrupled in size since we spun out from Rackspace two years ago, and we’ve been able to support this growth profitably and sustainably. 

Each step along the way has helped us get where we are today – from Y-Combinator, which strengthened our early technology; to Rackspace, which taught us about the power of support; and to Turn/River, which enabled us to achieve rapid growth. 

But it’s because of our customers that we’ve reached this point. Without the support we’ve received from the developer community, we would not be in this position. Our entire team works constantly to ensure the APIs and developer tools we build are worthy of that support. We couldn’t be more excited about what this investment means for our community.

Where we’re going

Most people expect there to be some changes when there’s a transition of ownership. In our case, the investors hate everything we’ve built and have asked that we radically change direction. As of today, we’re changing our name to Meowgun and focusing entirely on streamlining communication between cats and their owners.

Just kidding. Turns out, Thoma Bravo loves our developer-centric approach and believes there’s tremendous growth potential in the email infrastructure market Mailgun serves. 

We are continuing on our mission to build the most comprehensive API-first email delivery solution. With this investment, we’re able to accelerate our roadmap and provide customers with the next generation of developer-first communication tools.

We will be investing millions in the development of products you can use to enhance your deliverability, gain more insights into your emails, and deliver an unparalleled experience for your customers. We’re also doubling down on customer success and enablement to ensure our customers have exactly what they need to scale their communications.

Thoma Bravo has a proven track record of helping software companies achieve exceptional results with over $30 billion in assets under management and relevant past and present investments in companies like SolarWinds, SailPoint, and Blue Point Systems. We look forward to leveraging their experience as we begin the next chapter of the Mailgun story.

I can’t wait to share more details about what we’re working on next. Stay tuned!
