"We're doing GTM now." That's a sentence I hear inside companies — usually about two weeks before the planned product launch. What follows is a scramble of press releases, sales briefings, and marketing materials. What doesn't follow is an actual plan that ensures the product succeeds in the market.
Go-to-market isn't an event. It isn't a checklist. And it certainly isn't something someone can handle in three weeks on top of their regular job.
What go-to-market actually means
Go-to-market is the structured plan that defines:
- Who buys the product: ideal customer profile (ICP), buyer personas, decision-making units
- What the product solves for that customer: value proposition, differentiated positioning
- How the product reaches those customers: channels, sales model, messaging
- At what price and under what terms: pricing model, discount logic, packaging
- In what order: pilot market, rollout sequence, geographic expansion
A GTM plan without these five dimensions isn't a GTM plan. It's a wish list.
Who on the team is actually responsible?
This is where the most common mistake happens. In most companies, GTM is treated as either a marketing responsibility or a sales responsibility — but rarely both, and rarely with clear ownership.
A GTM team that works effectively includes:
- Commercial Lead / Product Marketing: Owns positioning, messaging, pricing, and packaging. Acts as the link between product and market.
- Sales Lead: Defines the sales model, target customer segmentation, and sales process. Brings real-world market insight into the planning.
- Product Management: Makes sure the product delivers what was promised at launch. Defines feature sequencing and rollout scope.
- Marketing: Demand generation, content, events, campaigns — but only after positioning and messaging are clear.
- Customer Success / Support: Needs to know what's coming before launch. Lack of CS involvement is one of the most common reasons for customer disappointment in the first 90 days.
GTM without cross-functional alignment is marketing activism. It creates noise, but no impact.
The four phases of go-to-market
How to define milestones that actually mean something
The most common mistake in GTM plans: milestones describe activities, not outcomes.
Weak milestone: "Sales training completed."
Strong milestone: "8 out of 10 sales reps can answer the top 3 objections without assistance (measured in a role-play assessment, score ≥ 4/5)."
Weak milestone: "Product page live."
Strong milestone: "Product page generates ≥ 50 qualified inquiries in the first 30 days."
The difference isn't trivial. Activity milestones are always achievable — you simply complete the activity. Outcome milestones force an honest look at the actual goal: did it work?
For every GTM milestone, answer these four questions:
1. What's the desired outcome? (Not: what are we doing? But: what are we trying to achieve?)
2. How will we measure it? (Concrete metric, source, time frame.)
3. Who owns it? (One person, not a team.)
4. What's the fallback if we miss the target? (No milestone without a contingency.)
The five most common GTM mistakes
1. GTM starts too late
GTM isn't a launch event. It starts the moment a product decision is made — not two weeks before launch. Positioning, pricing, and defining the target customer take time, market validation, and iteration.
2. The ICP is too broad
"All midsize companies in the DACH region" is not an ICP. The more precisely the ideal customer profile is defined, the more efficient the go-to-market effort becomes. An overly broad ICP leads to wasted spend, low conversion rates, and sales burnout.
3. No clear pricing model before launch
"Price on request" is not a pricing model. It's a signal that you don't know what your own product is worth. Pricing needs to be defined and communicated internally before the first customer conversation.
4. Sales isn't prepared
If sales can't explain the value proposition, if there's no ROI calculator, if nobody knows the most common objections, the launch will fall flat. Sales enablement isn't an add-on to GTM. It's a core part of it.
5. No feedback loop after launch
The launch isn't the end of GTM. It's the beginning of learning. What are the first customers saying? What surprises sales, positively or negatively? Which features never get used? Without systematic post-launch feedback, you're optimizing in the dark.
What good GTM costs — and what it delivers
A structured GTM project for a B2B product typically takes 6 to 12 weeks and requires 2 to 3 people working on it part-time. That sounds like a lot. But an unplanned launch tends to cost 3 to 5 times more — in rework, repositioning, sales friction, and missed market windows.
The question isn't whether you can afford GTM. It's whether you can afford to launch without it.
