In an effort to show developers that their work matters to Twitter, the company has announced it will be traveling to nine cities around the world starting in February. This event is part of chief executive Jack Dorsey’s #HelloWorld campaign to demonstrate that the company is listening to developers’ feedback and concerns.

The #HelloWorld developer world tour kicks off in Los Angeles from February 1 to 5 and travels around the United States before heading overseas to the United Kingdom, India, Japan, and finally Brazil. Each stop features a “main flagship event” hosted by Twitter and additional days where the developer relations team will meet with the community and organize office hours.

Here are the dates and locations:

  • Los Angeles: February 1-5
  • Seattle: February 8-12
  • Denver: February 15-19
  • Boston: February 22-27
  • New York: February 29-March 4
  • London: April 4-9
  • Bangalore: April 11-15
  • Tokyo: April 18-22
  • Sao Paulo: May 9-14

It was nearly three months ago at Twitter’s Flight conference where Dorsey stood on stage and publicly apologized to developers over the strained relationship between the two parties. “Somewhere along the line, our relationship with developers got confusing, unpredictable,” he said at the time. “We want to come to you today and apologize for the confusion. We want to reset our relationship and make sure that we’re learning, listening, and that we are rebooting.”

It’s there where he asked developers to submit ideas and requests to Twitter using the hashtag #HelloWorld. The company has been trying to make inroads with the developer community and plead for a second chance. Since Flight, it has held office hours using Periscope and launched a blog series it calls its Mobile app playbook, among other initiatives.

Twitter has done world tours before for developers, bringing its Flock developer conference to many of the above-mentioned cities. However, this time around, the messaging appears to be different: Not only does it appear that the company is spending more time at each stop (previously it was only a day), but the tone is less about telling developers what Twitter has to offer and is more about reconciliation.

The reason these nine cities were selected hasn’t been disclosed, but since many match up with stops Twitter made with Flock, it’s likely because there may be a large developer following in each location.
