How to Prospect Any Event with One GPT Workflow

Use AI to research attendees, identify prospects, and prep your outreach.

In case you missed it, I’ll be releasing a new course, “Prompts to Revenue: An Actionable Guide for B2B Sellers to Sell with AI” on Thursday June 26th, 2025.

I recently returned from Cannes, a week long, MASSIVE creative event. I was fortunate to meet a lot of interesting people and prospects (because of work, duh). Needless to say, there’s A LOT of sessions and events, happening day and night. To help me approach this efficiently, I asked myself:

Who can I connect with in target accounts?
What prospects from existing sales cycles are currently there?
Which sessions would be relevant to attend to get in front of relevant personas?

So today, I wanted to share a how I set up a custom GPT to efficiently sort through everything and answer the questions I had.

In some cases, say a smaller one or two day, niche event - a custom GPT might be overkill. But nevertheless, I wanted to share since the application might be helpful.

Here’s what we’ll cover:

• Custom GPT vs GPT workspace
• Prompting for Boolean searches —» Feed into Custom GPT
• Creating the Custom GPT

Custom GPT vs GPT workspace?

As I was writing this I realized that this may be a question that pops up. Quick breakdown:

• Custom GPT’s are great for specific tasks (ie help me find people at an event or help me write outbound emails templates).

• GPT workspaces are great for free flowing dialogues or ad hoc brainstorming (ie unique messaging across personas at various accounts)

I dive into more into how my workflows are set up in my course.

Prompting for Boolean searches —» Feed into Custom GPT

With all the talk around AI, it’s easy to over-engineer. Sometimes, it’s better to just do the regular human stuff like search on LinkedIn the good ol’ fashioned way: manually.

I’m not great at boolean searches but that’s what AI is for. In most cases you can ask how to boolean search with GPT. Here I just used the “event'“ keyword and filtered by the following:

1. Use outlined filters below
2. Filter by account and/or persona list
3. Input “event” keyword
4. optional: you can filter more with who’s following your company or recent job changes and/or use Clay to further enrich.

From there, upload those contacts into a CSV, along with event URL(s)/CSV(s) from the event and any other info you’ve received from your event/marketing team.

Creating the Custom GPT

After getting the CSV, you can then start building your customer GPT. Compile all the info above ie: list of accounts, relevant csv’s, and links/files to any sessions, agendas, dates, so that the custom gpt has all the info it needs to help.

Then prompt:

If this prompt doesn’t suit your needs - just ask to clarify or refine what matches best for you.

We’ll cover this in depth when Prompts to Revenue: An Actionable Guide for B2B Sellers to Sell with AI is released on June 26th.
