Co-sell has become the corporate growth lever everyone claims to want and few organizations actually run well. At its core, co-sell is a way of selling. Specifically, it’s a coordinated go-to-market approach in which two or more companies actively pursue and close a deal together, combining complementary products, services, or reach to solve a customer problem more completely. Used to accelerate pipeline and open doors into accounts a team might struggle to reach on its own, it has real potential to unlock new revenue streams, deepen customer relationships, and turn one-off wins into scalable growth.
Organic growth alone rarely unlocks the full addressable market, which is where co-sell can help. When done well, it allows companies to extend their reach through trusted partners who already have credibility, relationships, and distribution in target accounts. “Partners can access accounts that you can’t and they can shorten sales cycles by at least 30 to 40%, while increasing deal size through bundling,” says Bryan Lee.
“Co-sell motions fail when they’re designed for executives and not field teams,” he says. What looks coherent can risk collapsing at the “moment of truth,” like when a rep is on a discovery call and has to decide whether pulling in a partner will help or slow everything down. These “motions” simply refer to the repeatable process that guides how that joint selling actually happens in the field.
Bryan Lee, a strategic partnerships and go-to-market leader known for building repeatable partner systems across cloud, SaaS, and public sector environments, argues that if a motion does not hold up at the point of execution, it is not a true motion at all. It is theater.
The Difference Between Partner Strategy and a Usable Motion
Most co-sell programs are built backward, starting with what leadership wants to see instead of what frontline teams need to do. “I had the opportunity to work with and be a part of a lot of brilliant partner strategies that on paper – they look perfect,” he says, pointing to familiar artifacts such as executive sponsorship and strategic alignment. “But when I’d actually dive deep and ride along with the sellers, they had no idea when to actually bring the partner in.”
That’s the critical distinction: a partner strategy can be logically sound and still fail because it is not operationally legible. If a rep cannot recognize the right moment to attach a partner, the motion remains abstract. In practice, the rep defaults to the path of least resistance, even when leadership believes partners are a growth engine. Bryan Lee’s reset is to treat co-sell as a user experience problem as much as a revenue problem. The job is to create an action that feels obvious in the field.
A Three-Question Filter that Prevents Co-sell Shelfware
To close the boardroom-to-field gap, Bryan Lee goes back to basics. “Can your seller explain this in 30 seconds or less? If not, it won’t get used,” he says. The point is not to oversimplify a complex ecosystem but to make the first move frictionless. The second question he poses to address this gap is incentive-driven. “Does attaching the partner make the seller’s quota number bigger or their life easier? If it’s neither, it’s just shelfware.” If co-selling pays the same as a direct sale and requires extra coordination, reps will rationally avoid it.
Lastly, “Can we execute without the seller becoming a project manager? If the handoff requires five emails, it’s dead.” Co-sell that adds administrative load turns a revenue motion into unpaid labor. And once a rep learns the motion creates headaches, they usually do not come back. “The best co-sell motions are invisible to the seller,” he says. “They attach the partner because it’s the obvious path to close, not because leadership said to.”
Where Co-sell Breaks and What It Costs
Bryan Lee sees two failure modes repeating across industries: “misaligned incentives and undefined handoffs.” Each is damaging on its own. Together, they teach the field that co-selling is not worth the effort. On incentives, Bryan Lee calls out a common executive mistake: treating enablement as a substitute for comp design. “I’ve seen orgs try to fix this with awareness campaigns or better enablement,” he says. “But unless comp plans reward partner attachment… you’re literally fighting human nature.” He points to mechanisms such as accelerators, spiffs, and double crediting, because they match the operational reality that partner attachment requires coordination.
When incentives work, co-sell can change the economics of a deal. “Partners can access accounts that you can’t,” Bryan Lee says, and they can “shorten sales cycles by at least 30 to 40%” while increasing deal size through bundling. When reps avoid partner attachment, “you’re literally leaving 20 to 30% of addressable market on the table.”
The second failure mode is handoffs. Even motivated reps stall if the transition from seller to partner delivery is fuzzy. Undocumented handoffs create what Bryan Lee calls “coordination tax.” He’s seen six-figure deals die in month seven “because nobody owned the transition.” The downstream cost is reputational: burned trust with customers, frustrated partners, and a rep who decides, once and for all, not to co-sell again.
The Five Non-Negotiables for a 90-Day Rollout
Ask most leaders how they plan to launch co-sell and you’ll hear about training sessions and partner webinars. Bryan Lee starts with what forces adoption. “If a VP asks me for a 60- to 90-day rollout, here are the five non-negotiables”:
- Clear trigger criteria. Reps need a simple diagnostic for when to attach a partner.
- Single-click deal registration. “The user experience matters.” If the process is not frictionless, adoption stalls.
- Comp alignment. Partner attachment must be financially worthwhile.
- Documented handoffs. Bryan Lee keeps the bar low on purpose: “Three-step playbook. No ambiguity.”
- Executive P&L owner. Without ownership, co-sell remains a side project.
- Validate before you scale. Bryan Lee favors a small beta: “10 reps, 3 partners, 30 days.” If the attach rate is under 40%, he says, “fix the constraint before you scale. You don’t want to scale broken motions.”
AI Will Make Co-sell Faster, and Less Forgiving
Bryan Lee expects AI to reshape co-selling in two ways: “It’ll eliminate coordination tax and it also will expose bad partner strategies faster.” In other words, AI will reduce the operational overhead that kills adoption, while making it harder to hide vague motions behind leadership messaging.
He points to three areas where AI is already showing up: partner matching, pipeline prioritization, and playbook recommendations. AI can analyze a customer’s stack and past wins to suggest which partner to pull in, flag stalled deals that would move faster with partner support, and deliver context-specific battle cards at scale.
But Bryan Lee is as focused on the risks as the upside. “Data sharing without fair attribution poisons trust,” he says, and trust is hard to regain. Over-automation can flatten relationship nuance and black-box recommendations, meaning AI-driven suggestions that lack transparency into how or why they were generated, can backfire because “reps won’t trust what they don’t understand. Use AI to scale what works and not to mask what doesn’t.”
Repeatability is the real competitive advantage
Co-sell is often framed as a partnership initiative. Bryan Lee frames it as a systems discipline. When strategies stay “up top” and are not “battle-testing in the field,” he says, organizations burn “time, dollars and resources.” The leaders who win with co-sell do not merely announce alliances. They engineer repeatable motions that survive real selling conditions: quota pressure, imperfect information, and limited time. That is what turns partnerships from an afterthought into a durable growth engine.
