Intervention is an awesome 3 day conference for people who enjoy learning amazing things and collaborating with other motivated people on a wide variety of projects targeted at the Internet generation.

Our name is the combination of the words “Internet” and “Convention” but the significance is deeper than that. The entire idea of this event is to Intervene and Inspire everyone to live a more creative, geeky, and fun life.

Run by the same people who brought you the critically-acclaimed (Re)Generation Who Doctor Who Convention, Intervention has a similar fun scope to a comicon. This means we have video gaming, performances, board gaming, a Film Festival, and a full Children’s Department.

Past participants in Intervention have gone on to achieve prestigious jobs, higher salaries, and formed successful full time small businesses of their own. Our community is made of intelligent self-starters who are looking for people to collaborate with them on the next big thing.

“It’s the best con I know of that’s geared toward independent creators and helping people get their work out there, among other things (there are plenty of nerd culture cons, but this one is the most con-goer friendly if that makes sense) And there’s no air of superiority/holier-than-thou-ness from the staff of the con.”

- Phil Gorski, Intervention attendee

What is Onezumi Events?

Onezumi Events was founded in 2010 by Oni Hartstein and James Harknell. Onezumi Events immediately became synonymous with running events that are higher quality, welcoming to all people, and based in positive community.

Our experienced staff really cares that you have a great time and it shows. We believe in not just running events, but providing positive things for families to do together. Positive community changes lives.

We were one of the first major organizations to roll out an anti-harassment policy and to provide a safe space for all families, all genders. We’ve simplified and raised the bar on customer service at events.

Examples of what happens at our event:

I’ll let our track record speak for itself. Scroll back up and click the buttons on the right nav bar to get more information on what we do.

The best part? What we do changes and gets better every year. If you have something to contribute, you could be presenting. We are about the community – never about elitism. Elitism is for people who aren’t good at what they do.

This is how the next generation of Geeks get their party on.

    is there a minimum age for entry to intervention?

    • Harknell says:

      Hi Ben,
      Children under the age of 12 need to be with their parents at all times, so that would be considered the minimum age limit. 13 and above (with parental permission to be at the event) can do the events by themselves if they wish. We are a family friendly event (with a small number of 18+ events that will be clearly marked and restricted)

  3. [...] you are unfamiliar with our brand of geekery, look no further than our About Page, and the Archive on the top navigation bar for examples of what we did and will continue to build [...]

    Noob question
    how is thid convention different from other
    conventions and is there gonna be people cosplaying
    sori for the noob questions

    • onezumi says:

      Many people will be cosplaying, but we don’t have formal events for it yet. We are focused on educating people about how to put their stuff (comics, art, podcasts, videos, blogs) up online and monetize it.

      The other half of the con is a festival of indie geek artists, board and video gaming, fan geekery, and crazy performances like Harry Potter belly dance and Cosplay Burlesque. So if you are a creator looking for help or just a fan who wants a most excellent party, there is plenty to see and do.

    hey so cosplay is big! what are your rules for props (weapon props?)

  6. Lee says:

    Hi, there,

    I love the idea of your convention! I only wish that I can go, but I’m too far away and my time is sadly very limited. I see that you have some video up… will you post more video of the panels and events? Is there anything like what you do in the NYC/NY state area? Please let me know.



    • onezumi says:

      We intend to post more video – unfortunately last year a lot of the video did not come out. Hopefully it will be better this year.

      I don’t know of anything like us in NYC. We actually live in NYC/NJ but drive to MD to do this event because the costs are so high up there. If you decide to come one year, it’s really easy to get to us via Amtrak and BOLT Bus from NYC. :)

  7. Isabella says:

    do people cosplay, and if so what kinda of cosplays are there, can you wear any cosplay like from naruto to sailormoon?

    • harknell says:

      Hi Isabella,
      Yes, we do have Cosplayers at the event, and any of those outfits are fine. We have a few panels on cosplay design, so you might be interested in those. We may even have a small cosplay hallway contest happening this year, so look for that on Saturday.
