Jaiku

Jaiku was a Finnish microblogging service that launched alongside Twitter in 2006 and, on mobile, was arguably better. Google bought it in 2007, then did almost nothing with it for years while Twitter ran away with the market, before shutting it down in 2012.

Narrative

The story

The ambition

Jaiku was one of the two services that invented microblogging. Founded in Helsinki in February 2006 by Jyri Engeström and Petteri Koponen and launched that summer, the same season as Twitter, it let people broadcast short status updates and "presence" from their phones. Its mobile apps for Symbian and Nokia devices were sophisticated for the time, and it allowed threaded commenting that Twitter's simple "@" replies lacked. To many early enthusiasts, Jaiku was the better product.

The rise

That reputation attracted Google. In October 2007 Google acquired Jaiku, and the founders wrote that they looked forward to working with their "new friends at Google" to expand in interesting ways. On paper it was a formidable pairing: a well-regarded mobile-first microblogging service backed by Google's scale and marketing, aimed squarely at a Twitter that had only just raised its first $5 million.

The cracks

Instead, almost nothing happened. Google closed new registrations after the acquisition and then left Jaiku to stagnate. Over the next two years the company, as one account put it, "somehow managed to do absolutely nothing with it, even as rival Twitter rose in popularity." Twitter kept shipping, kept growing, and became the default, while Jaiku sat inside Google, starved of development.

The collapse

In January 2009, amid Google's first round of layoffs, the company announced it would no longer actively develop Jaiku. Rather than kill it outright, Google ported it to App Engine and open-sourced the code as JaikuEngine, leaving it online but abandoned. In October 2009 co-founder Jyri Engeström left Google to work on something that "makes meaning."

The aftermath

Jaiku limped on as an open-source curiosity until Google announced in October 2011 that it would shut the service down, which it did on 15 January 2012, the same wave of closures that took Google Buzz and iGoogle's social features. Jaiku became a standard cautionary tale about Google acquiring startups in a hot space and running them into the ground.

The lessons

An acquisition is a decision to invest, not a place to park a product. Jaiku had the earlier mobile lead and arguably the better technology, but a great service inside an owner that won't develop it will lose to a worse service that ships every week. Buying a promising competitor does nothing if you then neglect it, the market is won by whoever keeps building, and Twitter did.

Causal timeline

Failure Anatomy

  1. 2006

    One of microblogging's inventors

    Founded in Helsinki in February 2006 by Jyri Engeström and Petteri Koponen, Jaiku launched in 2006 alongside Twitter as a mobile-first microblogging and presence service, admired for its Symbian/Nokia apps. [1]

  2. 2007-10

    Google acquires Jaiku

    In October 2007 Google bought Jaiku, positioning a well-regarded mobile microblogging service against a Twitter that had just raised its first $5M; Google then closed new registrations. [2]

    Two years of neglect

    Google did almost nothing to develop Jaiku while Twitter grew rapidly and became the default microblogging platform. [3]

    Development ends, open-sourced

    In January 2009, amid Google's first layoffs, the company stopped developing Jaiku, ported it to App Engine and open-sourced it as JaikuEngine; co-founder Engeström left in October 2009. [5] [6]

Structured analysis

What Went Wrong

Root causes

Neglected after acquisition. After buying Jaiku in 2007, Google did almost nothing to develop it for two years while Twitter iterated rapidly and took the market. [3]

Twitter ran away with the space. Twitter kept shipping and growing to become the default microblogging platform, while a stagnant Jaiku fell behind. [3] [4]

Contributing factors

No clear plan for the acquisition. Google closed new registrations and never articulated or executed a strategy to grow Jaiku, treating it as a low-priority holding. [2] [3]

Immediate trigger

Google ends active development. In January 2009 Google announced it would no longer develop Jaiku, porting it to App Engine and open-sourcing it, which sealed its decline before the 2012 shutdown. [5]

Visible symptoms

Stagnation while Twitter grew. For roughly two years after the acquisition Jaiku saw little development as Twitter's popularity climbed. [3]

Warning signs

Registrations closed, momentum lost. Google closing new sign-ups after the 2007 acquisition, with no growth push, signaled the service was not a priority. [2]
