Decision-makers to target at architecture firms in St. Louis
When selling into architecture firms, three titles consistently convert better than broad departmental targeting:
- Managing Principal — typically owns budget approval for vendor selection in this space.
- Head of BD — typically owns budget approval for vendor selection in this space.
- COO — 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.
