Maximize Your Impact At DSEI 2025
DSEI 2025, scheduled for September 9–12 at ExCeL London, is one of the most powerful gatherings for global defense and security professionals. Bringing together government officials, military leaders, prime and subcontractors, and advanced tech suppliers, DSEI serves as a strategic cornerstone for defense procurement, policy discussions, and international partnerships.
The event is especially relevant for companies focused on innovation in defense systems, cybersecurity, aerospace, and communications. Attendees typically include senior procurement officials, program managers, CTOs, defense attachés, and private-sector executives with direct purchasing authority. Long procurement cycles make early engagement essential—decisions on future supplier relationships, strategic collaborations, and technology evaluations start well before the event begins.
Using Vendelux’s enriched attendee list, sales and partnerships teams gain visibility into which organizations are on-site, which programs are active, and who within those organizations holds buying power. This positions vendors to connect with relevant stakeholders ahead of time and shape conversations when it matters most.
How Sales, Marketing and Revops Teams Can Use This Attendee List
DSEI 2025 connects organizations working on complex, long-term strategic objectives within defense and security. Accurate targeting is key. With the Vendelux attendee data, your teams can segment contacts by military branch, contractor type, government sector, or company size to prioritize outreach based on relevance.
Identify key roles like defense program managers, procurement leads, and R&D officers with authority to begin new supplier dialogues. Align messaging to reflect current geopolitical challenges, modernization efforts, or specific defense capabilities, increasing the likelihood of securing meetings on-site. For those involved in defense technology or mission-critical systems, engaging with attendees ahead of the event helps unlock partnership discussions and vendor briefings while buyers are shaping budgets and evaluating tech stacks.
Use the enriched conference attendee list to track post-event engagement—whether through customer briefings, follow-up demos, or integrated proposals tied to programs discussed at DSEI. This is how to get more meetings and convert defense conference attendees into long-term contracts or project collaborators.
