Following Mobile 2.0 in San Francisco last week, a few people have asked us to share the slides from our CTO Stef’s presentation. So by popular demand, you can now view them here. Attended Mobile 2.0 and have feedback or questions for us? Get in touch, we’d love to hear from you.

The Mobile 2.0 Conference is being held in San Francisco on Monday, 3rd November and everything points to it being an excellent event. Excellent because we’ll be there of course! (Just kidding)

On Monday afternoon, our CTO Stef will be presenting as part of the Builder Track, on “Building, dynamic, compelling, ad-funded, off-deck mobile web content”. Many more great presentations on the schedule by Brian Fling, Kelly Goto and the likes of Nokia, AdMob and Facebook Mobile.

Steve (our CEO), Bob (our biz dev guy) and Stef will all be there, looking forward to meeting existing and new partners, and meeting you too. So don’t hesitate to come say hi if you see any of them!

Big excitement here at Taptu yesterday evening. After 8 months of design and engineering we went live with the first of our private beta invites. We’re keeping it to a very small early group for the first couple of weeks. Then we’ll be opening it up to a larger private beta before we launch at the Mobile 2.0 conference in San Francisco in the middle of October. Very promising early feedback so far, and now we’re just itching to take it public. (By the way, you can join the beta mailing list here)

Very nice of Rudy de Waele to praise our “super-simple design interface”. You can’t imagine how much effort has gone into getting this right. Since January we’ve run 7 studies in our new user experience lab testing different aspects of the UI, that’s 70 users giving us their candid opinion from hands-on use and abuse of our prototypes.

Our engineering team have done a pretty amazing job since we started in January. We took the decision to use open source infrastructure components wherever we could, but this still left a lot of gaps to fill if we were going to deliver on our goal of a fully-clustered, triple-redundant, fault-tolerant architecture running on commodity 1U servers, scaleable to millions of users. An architecture which also has to serve results pages in an optimised and reliable way to hundreds of different handsets across a multiplicity of GSM and CDMA mobile networks. Now we’ve taken a very big step closer towards this goal.

Our novel social-assisted search (SAS) approach means that we also have to write custom crawlers and parsers for each content category (music, movies, sports, etc) which we point at our selected social Web source sites. Now we have the basic infrastructure for all this in place we can begin to add additional content categories at a much faster pace. So expect to see a rapid expansion of the scope of our system over the next 6 months.

Today, Taptu is a universal mobile search engine, but the SAS optimization approach is only applied to music. With SAS switched on, we can give you useful results almost all the time in 10 clicks or less. Without it, we fall back to the 25 or more clicks that you normally see in today’s mobile search engines. So for searches outside music, Taptu doesn’t perform any better today than the big 3 mobile search engines (for us, the big 3 means Google, Yahoo and Microsoft) . This will change as we switch on SAS for other big categories like movies, travel, sport, games, and mobile web. Then you’ll really see what SAS can do.
