From Runa to Zolo Labs in 54 months

I’ve been at Runa for about four and a half years: I was there from pretty much from the beginning, and for the past couple of years, I ran the tech team as the CTO and VP of Engineering. We’ve built an amazing product, with quite a small team of engineers. We picked tools that gave us leverage, and I think to a large part, these choices let us stay small and lean.

We were among the first companies in the world to push a Clojure service into production… it was the fall of 2008, and Clojure was still pre-version-1.0. In those days, it still used Subversion for version control… and I remember having to tag commit #783 or something… so we’d be sure some unknown incompatibility wouldn’t derail us. We finally did an official release of that in Jan of 2009. Fun times :-)

Since then, we’ve grown our code-base to tens of thousands of lines of Clojure code, and have worked with HBase + Hive + MapReduce, Cascalog, RabbitMQ, Redis, MonetDB, Hazelcast, and loads of AWS services. We coded several state of the art machine-learning algorithms for predictive modeling. Rapunzel, our Clojure DSL, is used by several non-technical folks every day to support our merchants. It’s really neat stuff.

And the code is blazingly fast. For instance, we’re one of the only 3rd party services deployed inside eBay’s data-centers, and are called in real-time for their live pages. To be specific, we’re called about 100 to 200 millions times a day, with spikes of over a billion, and have an average response times of 640 micro-seconds. This service makes statistical predictions about [redacted], and runs over 800,000 models concurrently. Like I said – fun times…

More than anything, I worked with some incredibly talented people over these past few years… not just here in the Bay Area, but also in Bangalore, India. I think the work we pulled together as a team, and the relationships I’ve made with these people are what I’m most proud of…

This past month, though, was my last as Runa’s CTO. I’m still engaged as the chief technologist, but no I’m longer a full-time employee. Why did I leave? Well… it’s been a long time, and I’ve been itching to do this Zolodeck thing for a while. And I see good things in the future for Runa, and I’m certain these things will happen without me as well… the team is rock solid… which gives me confidence to start my own adventure!

Some of you know what we’re building – our first product is called Zolodeck – but there’s a deeper philosophy behind that choice. I’ll delve into that in another post soon, but for now I’ll just say we want to improve how people collaborate and converse with each other, whether with their friends and family, or when they’re at work.

And for the techie readers of this blog, yes, we’re using a lot of cutting-edge technology to build out this product including Clojure, Datomic, Storm, and ClojureScript. Here’s a link to a talk I did at Strange Loop last year, discussing some elements of our stack.

It’s an exciting time for me… I’ve been waiting to be an entrepreneur for nearly 12 years… and it’s finally here! Boy, do I feel anxious and excited. Anxcited?
