A joint GTM (go-to-market) proposal is a document prepared by two partner companies that outlines how their combined solutions solve a specific problem for a shared prospect, why they are pursuing the account together, and what the recommended next steps are. It is different from a standard sales proposal in that it must articulate the joint value — what the two products deliver together that neither delivers alone — and it is typically co-branded, giving both companies equal visibility. For alliances managers, writing a strong joint proposal from scratch for each co-sell opportunity takes two to three hours and is one of the biggest bottlenecks in the co-sell workflow. PartnerMesh generates the first draft automatically from CRM and partner program data.

What Makes a Joint GTM Proposal Different

A standard sales proposal is a one-company document: here is our product, here is our pricing, here is why you should buy it. A joint GTM proposal has a different job. It must communicate who each company is and what they do independently, what the two solutions deliver together that is better than either alone, why this joint solution is the right fit for this specific account's situation, how the partnership is structured, and what the recommended next step is.

The joint value statement is the hardest part to write and the most important part to get right. "Company A does X and Company B does Y and they work great together" is not a joint value statement. A joint value statement is specific to the prospect: "For a mid-market SaaS company managing partner relationships at scale, the combination of PartnerMesh's overlap detection and [Partner's] CRM attribution eliminates the manual process of account mapping and makes partner-sourced revenue visible in the same system where deals are managed."

The Five Sections of a Strong Joint GTM Proposal

Section 1: Executive Summary (100-150 words). State the purpose of the proposal — "We are reaching out jointly because both of our teams have been working with [Prospect] and believe there is a significant opportunity to deliver value through a coordinated approach." Name both companies, name the prospect, and give one sentence on the specific problem being addressed. Keep this tight.

Section 2: About Each Company (100 words each). Brief, factual description of each company — who they are, what they do, and the customer profile they serve. Avoid marketing language. The prospect is reading to understand whether these are credible companies with relevant experience, not to absorb brand messaging.

Section 3: Joint Value Statement (200-300 words). This is the core of the proposal. Describe the problem the prospect is facing, how each company addresses part of that problem independently, and how the combined solution addresses it more completely. Use language that is specific to the prospect's situation, their industry, or the specific use case that created the co-sell opportunity.

Section 4: Partnership Structure (100-150 words). Clarify how the commercial relationship works — does the prospect buy from each company separately? Is there a bundled pricing option? Who is the primary point of contact for each product? This section prevents the most common co-sell confusion: the prospect trying to figure out "who do I call if something goes wrong?"

Section 5: Recommended Next Steps (50-75 words). One clear next step with a timeline. "We'd like to schedule a 45-minute call in the next two weeks to walk through how the integrated solution applies to [Prospect's specific situation]." Specificity prevents the proposal from ending in vague "look forward to connecting."

What to Avoid in Joint Proposals

Generic joint value. If you could remove the prospect's name and send the same proposal to 20 other companies, it is not specific enough.

Two-company brochures. A common failure mode is two separate "About Us" sections with no joint content in between. This is two brochures stapled together, not a proposal.

Unclear ownership. If the prospect is confused about who is responsible for what — who sells them the product, who implements it, who supports it — the proposal creates anxiety rather than confidence.

Jargon. Both companies' inside language, technical terms, and category buzzwords need to be translated for the prospect. Write to the prospect's vocabulary, not yours.

Generating Joint Proposals with PartnerMesh

Writing a strong joint proposal from scratch takes two to three hours of focused work. For alliances teams co-selling across five or ten partners with multiple active deals each, that time accumulates quickly.

PartnerMesh generates joint GTM proposals automatically from the data already in the system: company and industry data from the CRM account record, partner program information (what the partner does, joint value statement template), account context from the overlap detection (deal stage, existing relationships), and account-specific framing based on the overlap type and deal trigger.

The output is a first-draft joint proposal that covers all five sections. Alliances managers review, add account-specific context, adjust the joint value statement to match the specific deal, and send. Total time: 10 to 20 minutes instead of two to three hours.

Frequently Asked Questions

What is a joint GTM proposal?

A joint GTM (go-to-market) proposal is a co-branded document that two partner companies send to a shared prospect to outline how their combined solutions address the prospect's specific problem. It covers who each company is, what the joint value is, how the partnership is structured, and what the recommended next step is.

Who owns the joint GTM proposal — the vendor or the partner?

Ownership depends on who initiated the co-sell motion. Typically, the company with the closer relationship to the prospect takes the lead on drafting and sending the proposal, with the other company reviewing and approving before it goes out. In PartnerMesh, the proposal is generated collaboratively and both reps review in the co-sell room before it is finalized.

How long should a joint GTM proposal be?

A joint GTM proposal should be concise — one to two pages in most cases. The goal is to communicate the joint value and the next step clearly, not to be comprehensive. Longer proposals create more reading friction and often obscure the joint value statement in supporting material. Keep it tight.

How is a joint GTM proposal different from a standard sales proposal?

A standard sales proposal focuses on one company's product, pricing, and value proposition. A joint GTM proposal centers on the combined value of two companies' solutions for a specific shared prospect. The joint value statement — what the two products deliver together that neither delivers alone — is the core content of a joint proposal and does not appear in a standard single-vendor proposal.
