About Us

Hibernating Rhinos, a global provider of database infrastructure solutions, empowers Fortune 500 companies and enterprises across the globe to process online transactions through an open source platform. RavenDB is the industry’s first fully-transactional, NoSQL ACID database that combines scalability, high-availability, speed and performance. The company produces two ORM tools, NHibernate and Entity Framework Profilers, that inspect, analyze and suggest improvements to database access patterns in applications. Hibernating Rhinos is headquartered in Hadera, Israel with offices in the U.S. and Poland and extends its reach through over 1500+ customers worldwide.

Our Story

Hibernating Rhinos was founded in 2008 by superstar developer Oren Eini. Many of you may know him by his handle, Ayende Rahien. Oren built a career going from company to company fixing bugs and performance issues inside their databases. From the beginning, Oren’s focus was the customer and anticipating their needs.

Based on his experiences, he developed a set of visual debuggers & profilers, Entity Framework Profiler and NHibernate Profiler that worked in real time to allow a development team to find out what was going on while they coded. He saw common problems occurring in the development of databases and wanted to prevent bottlenecks and fatal flaws early on in the release cycle that could save businesses time and money.

As he traveled the world fixing a wide variety of database challenges, he saw the same problems arising time and again. That’s where RavenDB was born, a database that solves the biggest problems enterprises and small businesses encounter before they even encounter them. Oren set out to answer the most challenging issues: Creating an easy to install, easy to use database that used the best that NoSQL database could offer, but was fully transactional so you didn’t lose this critical element an SQL solution gives you.

With high availability, high performance, zero administration, and self-optimization, RavenDB is trusted and employed by a global client base including Fortune 500 companies spanning several continents. The Hibernating Rhinos team is a leading global authority in open source NoSQL and document database architecture and design, and in the C# and .NET global open source programming communities.

Our Core Values

Improving Your Database Experience

RavenDB is easy to install, implement, and use. We want you to work with what you currently know about database management to utilize our new technologies to conquer the unprecedented challenges of Big Data coming in from mobile, the cloud, and IoT.

Zero Administration

We automate many of the things database administrators are expected to do manually. This expands the productivity of your IT staff, enabling you to deploy resources to other areas of your application development.

High Speed Database Performance

Your users have one demand of your database: To process their queries and transactions as fast as possible so your application can deliver the best user experience on the market. Lightning speed performance along with nonexistent time outs, freezes, or crashes makes your application the one users in your market want to use.

Enjoy the Best of Both Worlds

Whether using your first NoSQL solution, or combining RavenDB with a legacy SQL database, we want you to get the most out of NoSQL without having to sacrifice anything the relational world gives you. That is why we are fully transactional.

Solving Your Future Problems

With clients across so many platforms, countries, and industries, we are the first to see the latest problems users and developers encounter as they adapt their databases to a constantly evolving business environment. It is our top priority to solve the problems that are most likely to cause developers to hit a wall, and turn them into new features and fixes to make better use of your database.

We Invest in Your Success

It’s free to start. You can take a community license at no cost and begin using RavenDB with 3 cores, 6 gigabytes of RAM, and a 3-node cluster to see if it’s a good fit for your next project. We don’t profit off of tech support, making it as painless as possible to set up and use RavenDB. You only scale up to the professional and enterprise versions once your database is a stunning success.
