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 can either submit your change as a pull request on Github, or contact the NHibernate developers mailing list.

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.

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.

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.

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.

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.
