Most AWS partners know the phrase "co-sell." Far fewer understand what it requires week to week, or why their pipeline sits in ACE with zero movement. I spent over a decade inside the federal channel carrying a $28M annual partner quota and driving $48M in attributed pipeline. Co-sell was a daily operating motion, not a switch you flip. This post covers the real mechanics, the specific failure points, and what running it right looks like.

What AWS Co-Sell Really Is

Co-sell is a coordinated selling motion where an AWS partner and an AWS field seller pursue a customer opportunity together. The partner brings the solution, the customer relationship, or both. AWS brings its account team, its credibility with the customer, and in many cases, active deal support including funding. When it works, both sides close faster and the customer gets a more integrated outcome.

The infrastructure for this is ACE, the APN Customer Engagements platform. ACE is the system of record for every co-sell opportunity. Partners submit opportunities, track their status, and receive AWS seller referrals through ACE. It is not a CRM replacement. It is a co-sell coordination layer, and it only produces results when it is actively managed.

The core transaction in ACE is the opportunity. You create a record, attach it to a specific AWS account team, and request co-sell support. The AWS seller on that account either accepts, declines, or goes silent. What happens after that submission is where most partners lose the thread entirely.

ISV Accelerate vs. Standard Co-Sell: The Distinction That Matters

Partners who conflate ISV Accelerate with standard co-sell misread their own leverage.

Standard co-sell is available to any registered AWS partner in good standing. You submit opportunities in ACE, AWS sellers can choose to engage, and you work deals together. The seller's incentive is limited unless your solution maps to something they are already pursuing.

ISV Accelerate is a separate designation for independent software vendors whose products run on AWS and meet specific qualification criteria. Partners in ISV Accelerate receive a structured co-sell engagement model, dedicated co-sell resources, and AWS sellers have a stronger internal incentive to engage with those opportunities because of how deals are tracked and credited inside AWS. The deal acceleration funding and committed co-sell support available under ISV Accelerate is materially different from what a standard Registered partner gets. If you are a software company and you have not pursued ISV Accelerate qualification, you are operating the co-sell motion at a significant disadvantage.

The Week-Over-Week Co-Sell Motion

Co-sell is not a submission exercise. It is a relationship and cadence exercise that uses ACE as its record-keeping layer:

  • Build the AWS seller relationship before you need it. The most effective co-sell partners have established contact with AWS account executives, ISV PDMs, and local field teams before any specific opportunity exists. That relationship is what causes an AWS seller to take your ACE submission seriously.
  • Submit qualified pipeline, not exploratory contacts. Opportunities in ACE should have a real customer, a defined use case, an identified AWS service footprint, and an estimated close date. Submitting thin pipeline to hit a volume metric is one of the fastest ways to lose seller credibility.
  • Follow up within 48 hours of submission. The AWS seller has dozens of partners and hundreds of accounts. If you are not following up, you are not top of mind.
  • Use the opportunity update fields consistently. Partners who keep ACE fields current signal that the deal is real and progressing. Partners who leave fields stale signal the opposite.
  • Run a weekly pipeline review against your ACE board. Know which opportunities are aging, which need escalation to a PDM, and which are close enough to warrant AWS deal support or funding conversations.

Where Partners Actually Stall

After a decade inside and alongside the AWS partner ecosystem, the failure modes are consistent. They are operational gaps that compound over time.

No Qualified Pipeline in ACE

The most common pattern: a partner activates ACE, submits a few deals, gets no response, and stops. Those early submissions were not qualified. AWS sellers are measured on revenue. If your pipeline does not have a plausible path to AWS consumption, you will not get traction.

No Real AWS Seller Relationships

ACE is a tool. The relationships are what drive it. We consistently see partners in the APN for two or three years who have never had a real conversation with the AWS account executive covering their top three target accounts. The AWS seller did not decline because your solution is weak. They declined because you are a stranger submitting a deal on their account. The fix requires proactive outreach to AWS PDMs and field teams, participation in AWS events, and building a reputation as a partner that shows up with real deals and follows through. That takes months of consistent work.

Opportunities That Sit "Submitted" Forever

ACE has a status called "Submitted" that, for many partners, becomes a graveyard. Opportunities are submitted and never advance because neither the partner nor the AWS seller is actively driving them. The partner assumes submission equals action. It does not. Submission opens a door. The partner has to walk through it with follow-up, context, and urgency.

When we audit partner ACE accounts, we routinely see 60 to 90 day old opportunities still in "Submitted" status. At that point, the deal has closed without AWS involvement, died, or moved to a competitor.

MDF and Co-Sell Funding Left on the Table

Market Development Funds are available to partners who have active co-sell engagement and can demonstrate pipeline generation activity. Most partners either do not know what MDF they are eligible for, do not submit claims on time, or submit claims for activities that do not qualify. We see Select and Advanced tier partners leave tens of thousands of dollars in MDF unclaimed every quarter because no one owns the process.

Co-sell investment funding, available for deals in active co-sell with AWS, has similar issues. Partners do not ask for it because they do not know it exists or because their ACE pipeline is not healthy enough to trigger the conversation. A funded co-sell deal has materially better economics than one you run on your own resources. Leaving that on the table is a direct cost.

How to Run Co-Sell So It Produces

  • Assign a dedicated co-sell owner internally. This person owns the ACE board, manages the AWS seller relationships, tracks MDF cycles, and runs the weekly pipeline review. It cannot be a side responsibility of your sales leader who is also closing deals.
  • Build an ICP that maps to active AWS service areas. Know which AWS service areas have active go-to-market push in your target verticals and build your co-sell story around those. Your pitch is easier when your ideal customer is buying exactly what AWS is actively pushing.
  • Request referrals, not just co-sell support. AWS sellers can originate referrals to partners when they are working an account that needs a capability you provide. Most partners never ask. It is one of the highest-conversion pipeline sources in the APN.
  • Treat ACE hygiene like you treat your own CRM. Fields current, close dates realistic, stage accurate. Your ACE record is your credibility with the AWS field team.
  • Close the loop on every deal, win or loss. Update ACE, communicate the outcome to the AWS seller, and work toward a customer reference where appropriate. That reference strengthens your standing for the next co-sell cycle, tier reviews, and competency applications.

The Bottom Line on AWS Co-Sell

AWS co-sell is a real revenue lever for partners who operate it deliberately. The ACE platform, the ISV Accelerate designation, the MDF cycle, and the co-sell investment funding are genuine resources that can accelerate growth. But none of them are passive. They require relationship capital with the AWS field, qualified pipeline discipline, and someone inside your organization whose job is to manage the motion continuously.

Most of the partners we engage with have the right product and the right customers. What they are missing is the operational discipline to run the co-sell motion AWS sellers actually want to engage with. That is a fixable problem. If your co-sell motion is stalled, your ACE pipeline is aging, or you are not sure how to approach ISV Accelerate qualification, book a discovery call. We will tell you plainly where the gaps are and what it takes to close them.
