Choosing your motion: product-led versus sales-led growth

Most real companies blend the two. But you almost always have a *dominant* motion, and picking the wrong one wastes money and time.

Three Diagnostic Questions

Forget ideology. Diagnose your motion using three variables.

1. ACV (Annual Contract Value)

ACV is the average yearly revenue from one customer. It is the single biggest predictor of your motion.

• Low ACV (roughly under a few thousand dollars per year): PLG territory. You cannot afford a salesperson spending hours on a deal worth a few hundred dollars. The math does not work.
• High ACV (tens of thousands to millions per year): SLG territory. A human sales cycle is expensive, but a large contract pays for it many times over.

The logic is unit economics. If it costs you, say, an estimated few thousand dollars in salary and time for a rep to close one deal, that deal has to be big enough to justify it. Cheap products must sell themselves.

2. Deal Complexity

Ask: can one person understand and adopt this alone?

• Low complexity: A single user gets value immediately. Calendly schedules a meeting. Loom records a video. No committee needed. PLG works.
• High complexity: The purchase touches multiple departments, requires integration with existing systems, or needs IT and security sign-off. Think of software that manages payroll across a global workforce. That needs SLG because buying it is a group decision.

A useful signal: if your product requires a security review (a formal check of how you protect data, common in enterprise deals), you are probably in sales-led land.

3. Time-to-Value (TTV)

Time-to-value is how long from signup until the user feels a real benefit.

• Short TTV (minutes to hours): Perfect for PLG. The free trial or free tier proves value before anyone asks for a credit card.
• Long TTV (weeks to months): Needs SLG. If value only appears after data migration, configuration, and training, a free trial will not convince anyone. A salesperson and an onboarding team must carry the customer to the payoff.

The Slack Playbook: PLG in Action

Slack's growth came from a viral loop: a mechanism where using the product naturally recruits new users. One person adds Slack, invites teammates, those teammates invite others. The product spreads inside the company on its own.

Key PLG ingredients Slack got right:

• A genuinely free tier that delivers value, not a crippled demo.
• Fast time-to-value: you are messaging within minutes.
• Bottom-up adoption: individual teams adopt before management formalizes it.
• Expansion built in: more users and more usage naturally push the account toward paid plans.

The marketing implication: in PLG, your product experience *is* your marketing budget. You invest in onboarding, in-product prompts, and reducing friction rather than in a large outboundoutboundProactive outreach that pushes your message to targeted audiences through advertising, email, or direct prospecting, initiated by the seller rather than the buyer.Voir la définition complète → sales force.

The Salesforce Playbook: SLG in Action

For a large enterprise, adopting it means migrating data, retraining staff, and reshaping workflows. No individual can just swipe a card and roll it out.

So Salesforce built a sales machine:

• Account executives who own relationships and negotiate deals.
• Sales engineers who handle technical questions and custom demos.
• A defined pipeline with stages from lead to closed deal.
• Customer success teams who drive adoption after the sale so the customer renews.

The marketing implication: in SLG, marketing exists to *feed the pipelinepipelineAll active sales opportunities across the stages of the sales process, together with their combined potential value and probability of closing.Voir la définition complète →*. You generate leads through content, events, and campaigns, then hand qualified prospects to sales. Marketing and sales alignment is everything.

Why "Product-Led Sales" Is the 2026 Norm

The clean split is fading. Many successful companies now run a hybrid called product-led sales (PLS): users adopt via a free product, and sales steps in only when data shows an account is ready to expand.

Here is the pattern. A few employees at a large company start using your free tier. Your data shows the account now has fifty active users. That is a signal. A salesperson reaches out, not cold, but armed with proof the product already works inside that organization.

This is the best of both worlds:

• PLG lowers acquisition costacquisition costCustomer Acquisition Cost (CAC) is the total sales and marketing spend divided by the number of new customers gained in a period. It measures how efficiently you grow.Voir la définition complète → and builds internal champions.
• SLG captures the large enterprise contract when the moment is right.

Figma, Notion, and many others grew this way: bottom-up adoption first, enterprise sales layered on top once usage justified it.

The key enabler is product usage data. You need to track which accounts are growing so sales knows where to focus. This is why marketing, product, and sales increasingly share the same data.

How to Diagnose Your Own Motion

Run your product through a quick scorecard. Lean PLG if most answers are "yes":

• Can a single user get value without help?
• Is time-to-value under an hour?
• Is your ACV too low to fund a sales team per deal?
• Does usage naturally spread to other people?

Lean SLG if most answers are "yes":

• Does buying require multiple stakeholders or IT approval?
• Is your ACV high enough to fund human selling?
• Does value only appear after setup, integration, or training?
• Do prospects need customization to say yes?

A Common Trap

Do not copy the motion of a company you admire if your fundamentals differ. Plenty of teams try to force PLG onto a complex, high-ACV product and watch free signups churn because the value was never self-evident. Others hire expensive sales reps to sell a cheap, simple product and bleed money on unit economics.

Your motion should follow your ACV, complexity, and time-to-value, not your aspiration.

Marketing Metrics Shift with Motion

Your motion changes what you measure.

• PLG metrics: signups, activation rate (percentage of users who reachreachThe number of unique people exposed to your message in a given period.

Reporting the wrong metrics to leadership signals you have not clarified your motion.

Key Takeaways

• Your growth motion is a diagnosis, not a preference. Base it on ACV, deal complexity, and time-to-value, not on which company you want to imitate.
• Low ACV, simple product, fast time-to-value points to PLG. The product sells itself; invest in onboarding and in-product experience instead of a large sales force.
• High ACV, multi-stakeholder purchases, and long setup point to SLG. A human sales team and customer success are worth the cost when contracts are large.
• Product-led sales is the 2026 default for many. Acquire bottom-up through a free product, then let usage data trigger sales outreach for enterprise expansion.
• Match your metrics to your motion.
