Tech and product

We believe in building something useful!

We believe that a small team filled with smart and passionate people can accomplish anything they set their minds too. Great people make the difference. We value teamwork and clean code, we get excited about the challenges and opportunities of a web startup, and we constantly strive to improve every aspect of what we do. Building a great application that creates value for our customers, is easy to use, functions as a business, solves people’s problems, scales well and is easy to maintain is a huge challenge, but that’s what gets us out of bed in the morning.

Perfecting our craft

As software craftsmen, we know that we can never perfect our craft. There is always something more to learn, something that can be improved upon. We regularly attend London meetups, watch videos and add to our collection of books on programming, UX, design and databases. We eagerly share the knowledge we gain, with the rest of the team.

It’s all about our customers!

This concept permeates our culture, and the interface is the most visible example. We try to understand the people that use MyBuilder in every possible way. We talk to them on a daily basis, and invite them into the office to test new interfaces and features. We often take the testing to potential customers, doing guerrilla usability testing in local shops. We a/b test frequently, and strive to do more. We constantly improve our understanding of both the business priorities and the needs of our customers.

Lean & agile

Over the past few years, our development methodology has evolved into a system that works well for us. Since no system is perfect, we are committed to constant re-evaluation and improvement of the way we work. Honed from exploring various flavours of agile and lean, we believe that our way of working helps us get the right things done at the right time.

Object orientation

We believe that object oriented programming is the natural way to build our system - it allows us to model the real world in our code. We design our core libraries, data and model structures using appropriate design practices which helps us to rapidly evolve the website with minimal complications or bugs. We strive to keep a high level of code quality and cleanliness, which not only keeps us happy and productive, but also helps the business to succeed.

Symfony, a PHP framework

Symfony rocks! In our opinion, Symfony is by far the best implementation of an OO framework in PHP, making it a natural environment for us to work in. Mature, stable and well documented, it allows us to develop our system super fast while maintaining terrific quality code. It is the perfect match for us. It takes care of the CRUD, allowing us to put our heads together to solve the complex problems. We migrated our main website from Symfony 1 to Symfony 2 in 2013, and have started to use Symfony 3 on more recent projects. To help the Symfony community in London to grow we sponsored the Symfony Live London conference in 2012, 2013 and 2014, as well as give talks at the regular Symfony London meetups.


We don’t believe that testing is throwing a page at someone and asking them to have a look. Instead we believe that for you to be finished with a project that you need to have adequate unit and functional test coverage. We use PHPUnit, Symfony’s functional testing system and Jest. We have over 4,500 automated tests, with over 15,000 assertions, and a continuous integration system that screams when someone breaks it.


PostgreSQL was the best match for our needs, offering advanced features coupled with a high level of data integrity. To ensure data integrity, we take advantage of PostgreSQL’s triggers and functions by pushing some of our business logic into the database. For example: we use triggers to log data changes, which makes things more consistent and reliable. Postgres has allowed us to make the site faster by taking advantage of query optimisation features such as geospatial functions and partial indexes.
