Quick answer
The fastest way to find adtech companies in Chicago is to run a natural-language search on ProLeads: describe the role, industry, and city in a sentence and export verified contacts to your CRM. Expect 50–500+ matches for most mid-to-large metros, with 97% data accuracy on emails and direct dials.
Why Chicago matters for adtech sales
Chicago is known for derivatives trading, industrial headquarters, and food & beverage CPG. For sales teams selling into adtech companies, that mix creates a concentrated buyer base — and a signal-rich environment for account prioritization.
DSPs, SSPs, measurement, and identity vendors. In Chicago specifically, adtech companies tend to over-index on signal loss and margin, which is the angle your outreach should lead with.
Decision-makers to target at adtech companies in Chicago
When selling into adtech companies, three titles consistently convert better than broad departmental targeting:
- VP Sales — typically owns budget approval for vendor selection in this space.
- Head of Platform — typically owns budget approval for vendor selection in this space.
- CRO — typically owns budget approval for vendor selection in this space.
Layer seniority filters on top of the role — Director-level and above for platform buys, individual-contributor level for bottoms-up PLG motions.
