Foundations

Go-to-market strategy is the set of decisions that determine who you sell to, what you say, what you charge, and how you reach them — made before tactics, because every tactic inherits from them. Foundations is where those decisions get made and written down.

8 topics · each ships a deliverable and a way to run it

What Foundations covers

Foundations is the pillar of decisions you make once and everything else inherits from. Before you pick a channel, hire a rep, or write a landing page, you answer four questions: who is this for, what market are they in, what do we say to them, and what do we charge. Get these right and execution has a target. Get them wrong and competent execution just reaches the wrong people faster.

This is why Foundations sits above the funnel, not inside it. A go-to-market strategy is not a marketing plan — it is the set of upstream choices a marketing plan executes.

The decisions in this pillar

Each topic here produces a concrete artifact, not an essay. That is the test every GTM Institute topic passes: if you cannot name what it produces, it is not a library entry.

Decision The question it answers What it produces
Ideal customer profile Who is most worth selling to? An ICP doc, battlecard, and anti-ICP
Customer interviews What do those customers actually need? An interview guide and synthesis
Competitive analysis Who else are they choosing between? Battlecards and a landscape 2×2
Market sizing Is the segment big enough to matter? A TAM/SAM/SOM model
Strategic messaging What do we say, everywhere? Positioning, a value map, and headlines
Pricing & business model What do we charge, and on what metric? A pricing metric, tiers, and unit economics
GTM metrics How do we know it is working? A north-star metric and stage metrics

Why the order matters

The topics are sequenced because their outputs hand off. Your ICP is built from customer interviews. Your messaging is built from your ICP — the same nine elements that define your ideal customer define what you say to them. Your market sizing reads from the ICP too: you cannot size a market until you have defined whose market it is.

This hand-off is not just pedagogical. It is why the Positioning Chain exists as an agent flow: Customer Interviews → ICP → Strategic Messaging is three topics whose artifacts feed each other in order.

How to use this pillar

If you are taking a product to market for the first time, work the topics top to bottom — the sequence is the founder path through Foundations. If you are a GTM professional, treat each topic as a reference: jump to the one you need, use its workflow to produce the deliverable, and cite the framework.

Every topic gives you two routes to the same artifact. The workflow is you producing it by hand; the skill is the AI producing it from your inputs. Same deliverable, different means — that parity is the point.

How to build a competitive analysis framework

A competitive analysis framework is a repeatable way to map who you win and lose against, and why — not a one-time slide deck. The output is battlecards your reps use on live calls plus a landscape 2×2 that shows where you actually sit. Built from win/loss evidence, it tells sales what to say and product what to build.

What you'll produceBattlecards + landscape 2×2

How to run customer interviews that produce decisions

Customer interviews are structured conversations that surface why people buy, switch, or churn — in their words, not yours. Done right, ten of them tell you more than a thousand survey rows. The output is an interview guide plus a synthesis that turns transcripts into the patterns every downstream go-to-market decision inherits from.

Foundations

How to build an ideal customer profile (ICP)

An ideal customer profile (ICP) is the description of the company most likely to buy fast, stay, and refer — defined by nine concrete attributes, not a vague persona. It is the single decision every other go-to-market choice inherits from. Get it wrong and every downstream dollar targets the wrong buyer.

How to size a market with TAM, SAM, and SOM

TAM, SAM, and SOM are three nested estimates of a market: everyone who has the problem, the slice you can actually sell to, and the slice you can realistically win. Sized bottom-up from real unit counts and prices, they answer whether an opportunity is worth building for. Sized top-down from a report, they are theatre.

How to write a strategic narrative for your company

A strategic narrative is the story of a change happening in the world, why it makes the old way untenable, and why your company is the answer to the new one. It is not an origin story or a mission statement. Done right, it reframes the buyer's problem so your product becomes the obvious response — the frame every message, deck, and campaign hangs on.

How to build a messaging framework that sells

A messaging framework is the ordered set of claims that turns your product into words a buyer believes — a positioning statement, a value map linking features to the pains they solve, and the headlines that carry it. Built from your ICP and the customer's own language, it is what makes every page, ad, and pitch say the same true thing.

How to set a SaaS pricing strategy that scales

A SaaS pricing strategy is three decisions, in order: the metric you charge on, the tiers you package, and the unit economics that prove it pays. Get the metric right — the thing that grows as the customer gets more value — and pricing scales with the account on its own. Get it wrong and no amount of tier-tuning fixes it.

How to choose the SaaS metrics that actually run a business

The SaaS metrics that run a business are a single north star that captures delivered value, plus one metric per funnel stage that explains it. Most dashboards track the opposite — vanity numbers that rise while the business stalls. The output is a north star and a stage map: the few numbers a decision actually turns on, and nothing else.

What you'll produceNorth star + stage metrics

How AI changes foundations

AI compresses the research under every foundational decision — clustering customers, drafting positioning options, modeling a market. It does not make the decision. Foundations is the pillar where judgment matters most and automation helps least, because the output is a choice, not a document.

FAQ

What belongs in a go-to-market strategy?

A go-to-market strategy names the target customer (ICP), the market it sits in, the positioning and messaging, the pricing model, and the metrics that say whether it is working. Everything downstream — channels, sales motion, content — is an execution of these choices, not a substitute for them.

Where should a founder start in Foundations?

Start with the ideal customer profile. It is the decision every other go-to-market choice inherits from, and it is built from evidence you likely already have — your ten best customers. Market sizing and messaging both read from the ICP, so building it first makes the rest faster.
