GTM Strategy Spectrum
GTM Strategy Spectrum
Software businesses distribute their products across a spectrum of go-to-market models. Each position on the spectrum trades off different things: reach vs. revenue, scale vs. margins, speed vs. stickiness.
The Spectrum
FREE/OSS ←——————————————————————————————————————————————→ BESPOKE │ │ │ │ │ │Open Source SaaS/Self-Serve Custom BuildFreemium Sales-Led SaaS ConsultingDeveloper Tools PLG → Sales System Integrator Usage-Based Agency Model1. Open Source / Freemium (Left End)
Model: Give away the core product. Monetise through:
- Hosted/managed versions (GitLab, Elastic)
- Enterprise features (Redis, MongoDB)
- Support and services (Red Hat)
- Complementary products (Vercel/Next.js)
Tradeoffs:
| Advantage | Disadvantage |
|---|---|
| Maximum distribution | Zero direct revenue from most users |
| Community contributions | Support burden without payment |
| Developer trust | Competitors can fork your work |
| Hiring pipeline | Must find adjacent monetisation |
Tends to work when: Strong network effects, developer-first product, complementary revenue streams exist, category creation needed.
Historical examples:
- MySQL (1995) → Acquired by Sun for $1B, then Oracle
- Linux (1991) → Red Hat IPO’d at $3.6B (1999), acquired by IBM for $34B (2019)
- MongoDB (2007) → IPO at $1.2B (2017), peaked at $40B (2021)

2. Product-Led Growth / Self-Serve SaaS (Middle-Left)
Model: Free tier or trial, self-serve upgrade, expand within accounts.
Tradeoffs:
| Advantage | Disadvantage |
|---|---|
| Low CAC through virality | High churn on low tiers |
| Scales without sales team | Revenue per user is low |
| Usage data informs product | Support costs at scale |
| Fast iteration cycles | Hard to move upmarket |
Tends to work when: Product is simple enough to try alone, value is obvious quickly, natural expansion within teams/companies.
The PLG playbook:
- Land: Free tier or trial, no sales touch
- Expand: Usage grows, team invites, features gate
- Monetise: Convert to paid when value proven
- Enterprise: Sales assists large deals
Historical evolution:
- 1999-2005: SaaS emerges (Salesforce). Still sales-led.
- 2006-2012: Freemium rises (Dropbox, Slack). “Try before buy.”
- 2013-2018: PLG formalised (Atlassian, Zoom). Sales-assisted at scale.
- 2019-present: PLG expected for developer tools. Enterprise adds sales layer.

3. Sales-Led SaaS (Middle)
Model: Marketing generates leads, sales closes deals, success retains.
Tradeoffs:
| Advantage | Disadvantage |
|---|---|
| Higher ACV | High CAC (sales cost) |
| Multi-year contracts | Long sales cycles |
| Predictable revenue | Harder to iterate quickly |
| Deep customer relationships | Scales linearly with headcount |
Tends to work when: Complex products needing explanation, high ACV justifies sales cost, buyers aren’t users (procurement), compliance/security requirements.
The traditional SaaS metrics:
- CAC Payback: Months to recover customer acquisition cost
- LTV:CAC: Lifetime value vs. acquisition cost (target: 3:1+)
- Magic Number: Revenue growth efficiency
- Net Revenue Retention: Expansion - Churn (target: >100%)
Historical context:
- Salesforce (1999) launched “No Software” - the original SaaS positioning
- Workday (2005) proved enterprise SaaS works for mission-critical systems
- ServiceNow (2003) showed IT buyers would adopt cloud
- By 2020, SaaS became the default; on-premise is now the exception

4. Usage-Based Pricing (Middle-Right)
Model: Charge based on consumption rather than seats or features.
Tradeoffs:
| Advantage | Disadvantage |
|---|---|
| Aligns price with value | Revenue is variable/unpredictable |
| Land easily, expand naturally | Customers optimise usage down |
| Fair for small/large customers | Harder to forecast |
| Transparent pricing | Billing complexity |
Tends to work when: Usage correlates with value, customers vary widely in scale, API/infrastructure products, metering is straightforward.
The usage-based wave:
- AWS (2006) proved consumption pricing at scale
- Twilio (2008) brought it to APIs
- Stripe (2010) applied it to payments
- Snowflake (2012) used it for data warehousing
- OpenAI (2022) made it standard for AI APIs

5. Enterprise / Custom / Bespoke (Right End)
Model: Build specifically for one customer’s needs. High-touch, high-margin.
Tradeoffs:
| Advantage | Disadvantage |
|---|---|
| Very high revenue per customer | Doesn’t scale |
| Deep product insight | Risk of building wrong things |
| Strong relationships | Customer concentration risk |
| High margins per deal | Opportunity cost of time |
Tends to work when: Early stage needing revenue, complex integration requirements, learning what to build, establishing reference customers.
The “do things that don’t scale” argument:
Paul Graham’s famous essay argues startups should start with bespoke, manual, high-touch approaches before scaling. Applied to GTM:
- Find one customer who desperately needs you
- Build exactly what they need, even manually
- Extract the pattern that generalises
- Then automate and scale
Historical patterns:
- Palantir started with bespoke government contracts, later productised
- Stripe did custom integrations for YC startups before self-serve
- Slack was built as internal tool for one company (Tiny Speck)

A Brief History of SaaS
The Pre-SaaS Era (1960s-1999)
Mainframe timesharing (1960s): Multiple users shared expensive mainframe resources. Arguably the first “cloud” model.
ASPs (1990s): Application Service Providers hosted software for customers. Failed due to:
- Single-tenant architecture (expensive)
- Slow internet (poor UX)
- No self-service (high touch)
SaaS 1.0: The Salesforce Era (1999-2010)
Salesforce launched in 1999 with “No Software” positioning:
- Multi-tenant architecture
- Subscription billing
- Delivered via browser
- Still sales-led, but simpler procurement
Key innovations:
- Multi-tenancy reduced hosting costs
- AppExchange created ecosystem (2005)
- Force.com enabled platform extensibility (2007)
SaaS 2.0: Freemium & Consumerisation (2006-2015)
Dropbox (2007) proved consumer-grade UX sells enterprise:
- Viral growth via referrals
- IT departments bought what employees already used
- “Shadow IT” became a feature, not a bug
Slack (2013) perfected bottom-up adoption:
- Free tier for teams
- Self-serve upgrade
- Enterprise sales layer added later
SaaS 3.0: Product-Led Everything (2015-2022)
Atlassian IPO’d (2015) with no sales team, proving PLG at scale.
Zoom (2011-2020) showed PLG works for video too:
- Free tier sufficient for most users
- Quality differentiation drove word-of-mouth
- Enterprise features justified premium pricing
SaaS 4.0: AI-Native (2022-Present)
OpenAI and Anthropic introduced new patterns:
- Usage-based pricing by tokens/compute
- API-first with consumer wrappers
- Model improvements as product updates
- Inference costs as primary COGS
Emerging questions:
- How do AI wrappers differentiate?
- Does usage-based work when costs drop exponentially?
- What’s the moat when the model isn’t yours?
Where We Sit
Captain App’s products span the spectrum:
| Product | GTM Model | Why |
|---|---|---|
| SmartBoxes | PLG → Sales | Self-serve for individuals, sales for teams |
| P4gent | Freemium/PLG | Consumer product, low ACV, viral potential |
| Murphy | Sales-assisted PLG | Agency deals need relationships |
| Nomos Cloud | Usage-based + Enterprise | API product with enterprise overlay |
Our Bet
We’re betting on “land with PLG, expand with sales”:
- Products must be usable without talking to anyone
- Free tier proves value before payment
- Sales engages for team/enterprise expansion
- Usage-based pricing aligns costs with value
This is the Atlassian model, updated for AI infrastructure.
What We’re Not Doing
Not pure OSS: We don’t have the runway to give everything away and hope for monetisation later.
Not bespoke consulting: We don’t have the team to do custom builds for individual customers (though we will do “design partner” work to learn).
Not pure enterprise sales: We don’t have 12-month sales cycles worth of runway.
