Glossary
The language of go-to-market
A lot of go-to-market vocabulary gets used loosely. Here is how we define the terms in the C3 Method, so we are all working from the same meaning.
Go-to-Market (GTM)
The complete plan for how a company brings a product or service to its market: who you sell to, what you say, how you reach them, and how you win. Good GTM is not a campaign. It is the strategy the campaigns serve.
The C3 Method
A structured go-to-market framework that aligns sales and marketing around the buyer's real decision process. It moves a company from assumptions about the buyer to tested buyer truth, then to positioning, messaging, and action.
Buyer Truth
What buyers actually think, need, and weigh when deciding, learned from research rather than assumed. Buyer truth is the foundation the rest of a C3 strategy is built on.
Ideal Customer Profile (ICP)
A clear description of the companies and people you are best positioned to win and keep. A strong ICP covers firmographics (industry, size, geography) and the deeper fit signals that predict success.
Firmographics
The descriptive company attributes used to categorize a market: industry, employee count, revenue, geography, ownership structure. Firmographics are what make a market searchable in a prospecting tool, which is why so many ideal customer profiles stop there. On their own they describe who you can find, not why anyone buys.
Anti-ICP
An explicit description of the customers you should not pursue, even when they look qualified on paper. Every company has a deal type that looks strong in a pipeline review and painful six months later. Writing the anti-ICP down gives sales permission to disqualify early and sharpens the ideal customer profile, because defining the edges of something is how you find out what it actually is.
Target Market Segment (TMS)
A defined slice of the market you are going after, specific enough that its buyers share the same problems and buying behavior. Most companies serve more than one segment, and each deserves its own understanding.
Endemic Problem
The root pain that drives a buyer to look for a solution in the first place. In the C3 Method, you identify the core endemic problems for each segment, because they are what your messaging must speak to. A feature answers a question no one asked; an endemic problem is the question.
Compelling Value Proposition (CVP)
How your product or service solves a specific endemic problem, written as a promise: if you do this, it solves that problem and reduces its effect. Each endemic problem gets its own CVP.
Key Decision Maker (KDM)
The person who holds final authority in a purchase. Most B2B decisions involve several people, but the KDM is the one whose yes actually matters, and your strategy should know who that is.
Buying Center
All the roles involved in a purchase decision: the initiator, gatekeeper, controller, influencer, and decision-maker. Selling to a company means understanding the whole group, not just one contact.
Buyer Decision Journey
The stages a buyer moves through as they make a purchase decision. In the C3 Method there are seven: Need (the buyer realizes something is missing or could be better), Motivation (something turns that need into a reason to act now), Search (they start looking for ways to solve it), Evaluation (they compare options against what matters to them), Select Set (they narrow to a short list of real contenders), Decision (they choose, and justify the choice to themselves and others), and Confirmation (they look for reassurance they made the right call).
Positioning
How you want your company or offering to be understood in the buyer's mind relative to the alternatives. Positioning is a decision you make, then everything else expresses.
Messaging
The specific language that communicates your positioning and value to a given audience at a given stage. Messaging is positioning made speakable.
Key Selling Point (KSP)
A crisp statement of what you deliver, how you deliver it, and why you can: the company will deliver this value by this method because of this capability. KSPs turn strategy into things a salesperson can actually say.
Competitive Differentiator
How your approach to solving a problem genuinely differs from competitors solving the same problem. A differentiator is only real if a buyer would notice it.
Competitive Advantage
Why that difference is better and hard to copy, whether because it is exclusive, relatively stronger, or first to market. Differentiators describe difference; advantage explains why it wins.
Critical Success Formula
The repeatable operational method a company uses to deliver each value proposition. It is how the promise actually gets kept.
Core Competency
The underlying capability that makes the formula possible, whether knowledge, experience, partnerships, or resources.
Opportunity Evaluation
The Assembly AI capability that finds and ranks the right prospects against your own C3 strategy and explains the reasoning behind each score. It applies your strategy to real people, rather than handing you a generic list.
Sales and Marketing Alignment
The state in which sales and marketing work from the same understanding of the buyer, the same ideal customer, and the same view of how deals are won. In the C3 Method, alignment is not a standing meeting or a shared spreadsheet; it is the natural result of both teams building on one tested buyer truth.
Marketing Qualified Lead (MQL)
A lead marketing judges ready to hand to sales, usually based on a mix of fit and engagement signals. An MQL is only as good as the buyer understanding behind the criteria that define it, which is why redefining the threshold rarely fixes a lead quality argument on its own.
Sales Qualified Lead (SQL)
A lead sales has accepted as a real opportunity worth pursuing, after applying its own qualification. A persistent gap between MQL and SQL volume is usually a symptom rather than a process flaw: the two teams are working from different pictures of the buyer.
Total Addressable Market (TAM)
The total revenue opportunity available if you sold to every possible buyer of your product or service. TAM sets the outer boundary of ambition, but a go-to-market strategy actually lives in the far smaller slice you can reach and win today.
Product-Market Fit
The point at which a product genuinely satisfies a strong market demand, shown by buyers adopting it, staying, and recommending it. Product-market fit is read in buyer behavior, not declared in a meeting, and it comes far sooner when you understand how your buyers actually decide.
