Growth and monetization
Product-led vs sales-led growth
When self-serve wins, when you need a sales team, and how hybrids work.
Go-to-market (GTM) is how you take a product to customers: who finds it, who buys it, and whose labor sits between interest and revenue. Two poles dominate software debates: product-led growth (PLG), where the product is the primary driver of acquisition, conversion, and expansion, and sales-led growth, where humans (AEs, SEs, outbound) drive those motions.
Most successful companies eventually sit somewhere in between. The mistake is copying Slack's self-serve motion onto a $200k/year workflow that needs security review — or hiring a field sales team for a $12/month consumer utility.
This pairs with pricing and packaging and broader GTM strategy. Early on, many startups start with founder-led sales even if the long-term motion is PLG.
The deciding variable is ACV plus buying complexity. Low ACV cannot fund humans. High ACV rarely closes on a self-serve checkout alone. A widely used heuristic: under ~$5k/year is self-serve; ~$5–25k is inside sales or sales-assist; ~$25–100k is mid-market; $100k+ is field / enterprise. Default for ambiguous mid-market is PLG plus sales-assist on usage signals, not a field team first and not a forever ban on sales.
A practical sequence for startups: founder-led conversations to learn the job and price, remove friction until a segment can self-serve to value, add checkout, introduce sales-assist on product-qualified accounts, then hire specialized enterprise sellers only when ACV and win rates pay for them.
Concepts in this section
| Step | Concept | What it answers |
|---|---|---|
| 1 | Product-led growth | When the product can acquire, convert and expand on its own |
| 2 | Sales-led growth | When ACV and committees justify human time |
| 3 | Product-qualified leads | How usage, not form fills, hands work to sales |
| 4 | GTM and the roadmap | Which features "done" must include for this motion |
| 5 | GTM failure modes | Two funnels, bad comp, and enterprise features too early |
In interviews, when asked "should this product be PLG?", answer with ACV, buyer complexity, time-to-value, and whether usage creates distribution — then propose a hybrid if the answer is "both over time." Sketch the PQL definition in one sentence to show you know how sales and product share a funnel.
Common mistakes
- Copying another company's GTM without looking at ACV and time-to-value.
- Two funnels that do not talk. MQLs, signups and outbound lists in parallel.
- Sales-led habits in a PLG product (demo-gated trials, hidden pricing).
- PLG dogma in an $80k+ market that needs security review.
Key takeaways
- PLG uses the product to acquire, convert and expand; sales-led uses humans as the primary driver.
- ACV and buying complexity decide how much human labor you can afford.
- Hybrids and PQLs are the common end state: product creates pull, sales amplifies it.
- Roadmaps must match motion. Copying GTM from a company with different ACV is a common failure.
