leetspeak 2013



Where is it, what’s new, and what remains ever-awesome.


Let’s talk Leetspeak

Leetspeak is a conference born out of the desire to bring inspiring, hardcore technical content to those who need to know.

Launched in 2012 by the dedicated knowledge based firm, tretton37, it’s an event that is aimed at developers who are excited to stay at the forefront of the knowledge game, with a spotlight on the .NET developer who knows there’s honey to be had beyond the domain framework.

Community is a cornerstone of the tretton37 mentality. Leetspeak is another way in which the company is reaching out to fellow developers who want to connect and learn from others in the region and beyond.


Supporters are the ones who bring it – organizations and individuals multiply the goodness to bring an even better experience to attendees. Without these believers, Leetspeak wouldn’t have accelerated at such a fast pace or garnered the attention and praise we are so fortunate to have received.

These are the people who put their money where their mouth is; investing in their community because it’s the best way to give back. We are really happy that they have recognized the unique value in what we are all about.

For this we say to our supporters: Thank you for believing in us – we’re gonna make you proud!

What to expect

Leetspeak is aimed at developers who want to improve their craft. There’s content for web and .NET developers, and for anyone who’s seeking for something new to learn.

Those attending the conference can expect a few things: predominantly, the sessions will provide ideas and tools that can be used in a developer’s daily work.

You will learn from speakers who are masters in their fields, and meet new people who share your passion – all before the backdrop of our beautiful capital city.
