Documented cause
Jaiku launched in 2006 as a microblogging and mobile status-sharing service — conceptually similar to Twitter but with richer context (including location, calendar events and mobile presence information). Google acquired Jaiku in October 2007, in what appeared to be a direct competitive response to Twitter's growing momentum. But Google moved Jaiku to Google App Engine, froze new user registrations, and reduced the team to maintenance mode. In 2009, Google open-sourced the Jaiku codebase, effectively signalling it had no further commercial plans. The platform shut down in 2012 while Twitter was approaching 100 million active users.
Lesson
“An acquisition made for defensive reasons must be followed by offensive investment. Buying a competitor and putting it in maintenance mode solves nothing — the threat migrates to a new challenger while your acquisition decays.”

FAQ
What made Jaiku technically different from Twitter?
Jaiku aggregated multiple streams — not just text status updates but also mobile location, calendar events and RSS feeds from other services — into a single activity stream. The concept anticipated the interest-graph approach that Facebook later built with its News Feed and Open Graph. In 2007, Jaiku was arguably more complete as a product than Twitter.
What happened to the Jaiku founders after Google?
Jyri Engestrom became a well-known voice in the tech community, particularly around "object-centred sociality" — the idea that social networks should be built around shared objects (photos, songs, places) rather than just people connections. Petteri Koponen co-founded Lifeline Ventures, a Nordic VC firm. Both remained active in the technology industry.
