What is product-led sales? PLS vs PLG, signals and an example

What is product-led sales?

Product-led sales (PLS) is a go-to-market model that combines a self-serve product with a sales team. Customers start on their own, through a free plan or trial, and salespeople reach out to the accounts whose product usage shows they are ready for more: a larger plan, more seats, a company-wide rollout. Usage data, not form fills, decides who sales talks to.

It grew out of product-led growth as companies found that pure self-serve leaves money on the table with larger customers, who need help with procurement, security review and rollout.

PQLs and PQAs

A product-qualified lead (PQL) is a user whose behaviour shows buying intent. In B2B, buying decisions are made by organisations, so PLS usually scores product-qualified accounts (PQAs): all users from one company together. Five active users at one company is a stronger signal than one very active user.

Usage signals and a sample score

Sample scoring for a B2B SaaS. An account with 60 or more points is a PQA.

Weights should come from your own data: compare how often each signal appears in accounts that later upgraded versus those that did not, and adjust each quarter.

A worked example

Sample data for one quarter: 2,000 free workspaces.

Sales worked 140 accounts instead of 2,000 and produced 31 of the 68 conversions. Two cautions: PQAs would have converted at a higher rate even without sales, so measure the uplift by holding back a random 10–20% of PQAs that sales does not contact; and track deal size, because the point of PLS is usually larger contracts, not more of them.

When product-led sales fits

• A self-serve product that delivers value without a salesperson.
• Customers ranging from individuals to large companies.
• Larger deals that justify a salesperson's time and need help (security review, invoicing, onboarding many users).
• Usage data at account level that sales can actually see.

Pitfalls

• Calling every sign-up. It annoys self-serve users and wastes sales time.
• Vanity signals. Logins are weak; signals tied to value and expansion are strong.
• User-level data only. Without accounts you cannot see a company adopting the product.
• No holdout, so nobody knows whether sales added anything.
• Exposing personal browsing to reps. Share account-level signals; keep individual behaviour to what your privacy notice covers.

Product-led sales data in TapCub

• Accounts. Call tapcub.group('company', 'acme', { name: 'Acme' }) after login and events roll up to the account in All-platform analytics › Users › Accounts, with members, 30-day activity, top events and a 0–100 health score (40 points for the share of members active in 30 days, 30 for active days, 30 for recency). See analyze accounts with groups.
• Account identity in funnels and retention answers organisation-level questions, such as how many accounts reach "3 active users".
• Segments turn the PQA rules into a reusable list, refreshed daily.
• Proactive chat on the pricing or security page gives high-intent accounts a human without a cold email.
