Detecting Co-Selling Signals

3 min read

Co-selling — when two vendors jointly pursue customer deals — is one of the strongest partnership signals because it involves shared revenue and shared reputation. Co-selling signals are detectable before public announcements: joint webinars, co-branded content, shared booth presence at events, and cross-referencing on each other's websites. The progression from general partnership announcement to active co-selling typically follows a predictable pattern: announcement, integration development, co-branded content, joint events, and finally, joint customer engagements.

Do This

  • Track the co-selling progression signals: joint content, shared events, customer reference sharing — each stage indicates deepening commitment
  • Monitor for exclusive vs. non-exclusive co-selling arrangements — exclusive arrangements signal strategic partnership; non-exclusive arrangements signal channel strategy
  • Watch for co-selling in your customer accounts — a competitor partnering with a vendor your customer uses creates a threat you need to address

Avoid This

  • Treat every partnership announcement as a co-selling arrangement — most partnerships never progress to active co-selling
  • Ignore co-selling signals from vendors in adjacent markets — co-selling partners in adjacent markets often expand into your market together
  • Assume co-selling arrangements are permanent — they dissolve when the partnership dissolves or when one partner develops competing capabilities

The intelligence value of co-selling detection is highest when it involves your customers or your market segment. If two ecosystem players begin co-selling a joint solution that competes with your offering, you need to know before they approach your accounts. Your CRM data can help: cross-reference your customer list with both partners' customer bases to identify the accounts most likely to be targeted by the co-selling arrangement.
