I have no plans of participating in a Twitter pitch event. That said, I'm curious in anyone knows, how many of the writers who get interest actually get a publishing deal out of it? Whether x out of y who get offers or x% who get offers evenutally get published. There might not be numbers. If there are numbers, there might not be an AW member who knows that.
I'd assume the agents and/or publishers don't sign a contract based on a pitch, any more than an agent signs a manuscript based on a query letter alone.
If we ever got any significant data on any topic out of the industry, it would be quite shocking. The only time we even got a glimpse was during a merger trial.
The Manuscript Academy podcast featured a feminist horror author named Rachel Harrison, who found her agent that way. She prefaced her publishing story with "everyone is going to hate me." She made a tweet, went for a walk, and landed an agent days later. I also believe her deal with Berkley Publishing, a subsidiary of Penguin Books, came rather quickly.
I know an un-agented author through my old writing circle who had a heavy interest during a couple of pitch contests and is still looking.
I got three likes during the last two contests I did. One was from a scammer, and two were from agents who never replied to my query.
In the future, I will likely only participate in Unhinged Pit on BlueSky because it's a fun way to meet other aspiring authors when it was on the other place. Also, Dark Pit if it ever moves. The big ones seem to be falling by the wayside. But if they picked up again, I would participate in them.
Like everything else in publishing, it's part of the constellation of high-effort poker games (contests, querying, submissions.) A select few get deals through effort, talent, and luck, but most don't.
