Please note that due to political reasons, not all companies wish to disclose details of their usage of NHibernate. However we are still trying to gather success stories for NHibernate.
If you wish to add you own, you are more than welcome to do so.

Hibernate and NHibernate are recommended technologies for all new software we build. We have developed a framework using C#, and this framework uses NHibernate as the default technology for its Data Access Layer.
We have been using NHibernate, with great success, to develop medium and large software projects.

Hi, I'm from Latvia and the company i work for, uses NHibernate with cuyahoga-project for intranet systems and some other projects(for customers) like web shops and intra-extranets.
I used Nhibernate for a small credit app, which allowed sending credit in xml to a credit register. Numuri.lv runs on Nhibernate. Numuri.lv allowes latvian phone companies to exchange phone numbers when a user is switching to another.
Ebay reported by Steve Bohlen
EBay has built their entire auction-handling infrastructure atop Hibernate for Java, and since NHibernate offers the same capabilities in the .NET world, it is valid aswell.

Hi all, we are using NHibernate, Windsor, NQuery in a lot of big projects (including but not limited to EFT, Cash Flow etc) at Turkey branch of one of the biggest banks of the USA. Those projects manage a lot of transactions per day and we are very satisfied with it.
I´m from Peru, we are using NHibernate to develop the project SIGMA PORTAL, this is a tool for the management of human resources; it allows managing personal, financial and job information in an efficently way. currently SIGMA-PORTAL is used in many big companies in our country, Peru also Spain and Portugal
We are using NHibernate in the products we develop for the medical research industry. By using NHibernate, our development and maintenance costs have been reduce and we are easily able to support database independence for our products. Thanks NHibernate!

We use NHibernate on a number of N-Tier web applications for an intermediated general insurer in Australia ranging from small quotation sites to a large full lifecycle policy administration system. The largest has over 400,000 lines of executable code (1.5 Million raw lines) and uses NHibernate to persist to a schema with over 150 tables - we did this without a single stored proc. This site supports over 500 concurrent users and 15000 registered users. NHibernate was a key enabler to the sucess of this project and other projects within the organisation.

We are an American company, that develops its own products since 1994 in USA, India, Argentina, Turkey, and other countries. Nowadays we are releasing the second version of a brand new product, built using NHibernate, ASP.NET and Windows Forms, with really great performance results.
Integro reported by Diego Jancic
It's an Argentinian company that provides benefit to the employees of different worldwide companies (commonly only in Argentina, Uruguay and Chile), including Coca-Cola, Santander Group, and others. The system had a very big load considering the low hardware used and performed well, even the developers were starting with NHibernate.

It's a Spanish company that provides software for sysadmins that want to control remotely the entire life-cycle of their fleets of PCs. There were some parts of it's server side software that started to use NHibernate, but there's a lot of legacy code and not all has been migrated.
Pronet-ISE reported by Sergio Castillo
We are a Spanish IT Consulting company, specialized in advanced tech solutions about management, logistics and production control.
Now we use NHibernate and some contrib projects (NHibernate.Burrow, NHibernate.Validator) to implement a new architecture for the next release of our products. We consider that using NHibernate allow us to make maintainable and high quality software agilely.
I am the COO at a Boise, ID based mobility company. Whenever possible (approx 10-15 applications) we use NHibernate in the server side component of our mobility solutions. I've used this product for many years and am constantly amazed by both the ever improving functionality and the incredible support of the community. If you have concerns about bringing an OSS product into your tool stack then I urge you to take this one for a spin. I am certain if you are prepared to invest some time into learning the paradigm that you will quickly wish that you had taken the plunge years ago.
We are Senior Developers at a large format print company, Hudson's also a developer on the Fluent NHibernate project. We use NHibernate exclusively on an EAV greenfield project that allows our clients to manage their proprietary data. It's been an absolute dream, especially coming from a pure ADO/Dataset world where Stored Procedures drove much of the data access, to using a near seamless ORM like NHibernate. We weighted NHibernate against the Entity Framework, and a few other ORMs (such as ORMapper) and NH came up well ahead of the rest as the leader of the pack. It's a very mature framework, and we have nothing but appreciation and respect for the community that continues to improve this OSS product.
Prior to actually using NHibernate, I had heard rumors from other developers that NHibernate had a really steep learning curve, and had been a stumbling block for certain, well... 5:01 developers. We are using Castle ActiveRecord (layered on top of NHibernate) at HSI for a couple of our new LOB products, and it couldn't have been easier to get it set up and start being productive. It was just as easy to set up and use as other ActiveRecord OR/Ms I have used in the past like SubSonic and Linq2Sql, and from my perspective there is a lot more flexibility in terms of modeling entity graphs whose structure varies from the underlying database schema. (Castle ActiveRecord actually supports much more than just the "Active Record" pattern of one object per table.) It has been relatively easy to configure one class that corresponds to several tables, as well as several classes that correspond to a single table, and any sort of sane mapping of an inheritance hierarchy to a DB schema seems to be supported as well, so you really get the best of both worlds IMO with Castle ActiveRecord (all the ease-of-use of an "Active Record" type OR/M, coupled with the flexibility of NHibernate- since if necessary it seems that you can mix-and-match Castle ActiveRecord with 'plain vanilla NHibernate' in the same app). I would highly recommend Castle ActiveRecord (and thus NHibernate) to anyone that is trying to select an OR/M for their .NET application. If you don't like putting persistence information in your entities, you can use Fluent NHibernate, which I have heard provides equivelent functionality to Castle ActiveRecord, but it supports POCOs, although I have not used Fluent NH.
Undisclosed company reported by DuvallBuck
We have been developing solutions for world-class companies using NHibernate since 2006. Among the several solutions we built, there are internet-faced applications with more than 60.000 users and online transactional systems. The use of Nhibernate allow us to reduce the time spend on writing code for persistence and at the same time concentrate more on other concerns like business logic and user experience.
BP (British Petroleum) & Loomis reported by Scott White
Used NHibernate as ORM of choice at several companies. It is the most capable and pure ORM, there is little to no performance implications for using NHibernate due to it's flexibility.
