Why Illinois Sales Events Matter for Shoppers and Businesses
Illinois sits at a commercial crossroads in the Midwest. Chicago's McCormick Place ranks among the largest convention centers in North America, hosting industry-defining trade shows. Meanwhile, suburban and rural communities maintain traditions of monthly flea markets and annual craft fairs that draw regional crowds.
For consumers, these events offer access to antiques, handmade goods, vintage items, and deep discounts outside traditional retail channels. For businesses, they represent concentrated opportunities to meet buyers, showcase products, and build relationships face-to-face.
The challenge for exhibitors is execution. Collecting business cards is easy. Converting those contacts into qualified opportunities requires systematic follow-up that most sales teams struggle to execute manually. This is where AI SDR platforms become valuable, automating personalized outreach to event contacts while sales teams focus on closing deals.

Maximizing Event ROI with 11x: AI-Powered Pipeline Generation
For businesses exhibiting at Illinois trade shows and expos, the real challenge is not generating interest on the show floor. It is converting that interest into qualified opportunities after the event ends.
Most exhibitors collect hundreds of contacts but struggle with systematic follow-up. The typical result is contacts go cold, promising conversations never materialize into meetings, and the event investment underdelivers on ROI.
11x is an AI-powered digital worker platform that transforms how businesses execute go-to-market strategies and generate pipeline from events. Instead of relying on sales reps to manually email each contact, 11x's digital workers automate the entire post-event workflow.
How 11x Works for Event Follow-Up
11x deploys two specialized AI workers for event pipeline generation:
Alice (AI SDR) handles outbound follow-up after the event. Alice can research each prospect, personalize outreach based on their company context, and follow up across email, LinkedIn, and phone until they book a meeting or opt out. This eliminates the manual work that causes most event contacts to go cold.
Julian (AI Sales Agent) handles inbound inquiries from event attendees who visit your website or fill out forms. Julian AI Sales Agent qualifies leads in real-time through conversational voice and chat interactions, books meetings directly into rep calendars, and ensures no hot lead waits for follow-up.
The platform uses signals and triggers to identify which contacts show buying intent, prioritizing follow-up with prospects demonstrating recent funding rounds, technology adoption, job changes, or other indicators of purchase readiness.
Real Results from Event-Driven Pipeline
The combination of face-to-face relationship building with AI-powered follow-up execution creates a pipeline generation system that scales without proportional headcount increases:
- BuildWitt sources over 40% of meetings through 11x in under 3 months, while recovering 50% of SDR time previously spent on research and sequencing.
- Questex created $1M+ in pipeline in their first three months, automating roughly 2,000 hours of manual work per month.
- Checkr scaled outbound motion without adding headcount, using Alice to handle high-volume prospecting while reps focus on closing.
For businesses attending IHCC Business Expo, PACK EXPO, or other Illinois trade events, this approach turns event investments into predictable pipeline.
Pricing
11x publishes clear starting prices, making it easier to evaluate than quote-only AI SDR platforms.
- Alice, 11x's outbound AI SDR, starts at $3,750/month, billed annually, with pricing based on leads rather than sends.
- Julian, 11x's inbound AI sales agent, starts at $5,333/month for Voice and $2,417/month for Chat, billed annually.
The structure is simple: Growth plans publish starting prices, while Pro and Enterprise plans scale based on volume, users, channels, integrations, and support needs. 11x also bundles core infrastructure into its pricing, including CRM sync, onboarding, deliverability support, mailbox setup for Alice, and phone/chat infrastructure for Julian. This makes 11x's pricing easier to model against SDR headcount, outsourced appointment setting, and fragmented outbound or inbound tooling.
