Co-selling is a vendor and a partner working the same opportunity together, each contributing what they have: the partner brings the relationship and the account context, the vendor brings the product expertise and usually the commercial terms.
Also called: co-sell, collaborative selling, joint selling.
It sits between referral and reselling. In a referral the partner introduces and leaves. In a resale the partner owns the transaction and you may never meet the buyer. In a co-sell both sides are in the room, which is why it produces the largest deals and the most administration.
The reason it works is that neither side can close the deal alone. The partner has the trust and cannot answer the technical questions. You can answer them and would not have got the meeting. Buyers can tell the difference between that and a vendor being introduced by someone who wants a fee.
A shared view of the opportunity, and agreement on who does what before the first call. Most co-sells fail on the second one. Both sides think they own the pricing conversation, or neither does, and the buyer gets two answers.
It also needs the deal to be visible to both teams without either exposing its whole pipeline. That is a permissions problem before it is a process problem, and it is the reason co-selling over email tends to collapse into one person forwarding updates to everybody.
Usually a commission on the closed value, at a rate set by the partner's tier rather than negotiated per deal. Per-deal negotiation is common early on and does not survive scale: once several partners are co-selling, a rate agreed in a Slack thread is a dispute waiting for quarter end.
The other model is a margin split where the partner invoices the customer, which changes who carries the payment risk and usually who owns support.
How Airstride does it
Airstride gives both sides one view of a shared deal, scoped so a partner sees their own opportunities and nobody else's.
