An executive guide for growth leaders building revenue engines that scale
Why Most Startups Overestimate Their Market and Underestimate Their Focus
Most startups spend months calculating their Total Addressable Market (TAM) for investor decks but can't tell you how many accounts they can realistically close this quarter. That gap is where GTM strategies collapse.
The Total Relevant Market (TRM) changes that. Instead of chasing everyone, TRM defines who you should pursue right now. At Phi Consulting, companies that define their TRM early scale faster and hit numbers more predictably through GTM consulting.
The test: Can you answer "how many accounts can realistically get us to our next ARR milestone" in under 60 seconds?
What Happens When You Sell to Everyone
When everyone is your buyer, no one becomes your priority.
The reality:
Your sales team chases dead ends
Your marketing scatters across segments that don't convert
Your product roadmap gets pulled in every direction
Take TruckX as an example. When Phi helped them focus their GTM execution, they scaled from $2M to $16M ARR in 18 months. That's TRM precision creating leverage.
TRM vs TAM vs ICP: Understanding the Hierarchy
Most executives confuse these. Here's how they work:
Concept | What It Means | What It Does |
TAM (Total Addressable Market) | Everyone who could theoretically buy | Funds your pitch deck |
TRM (Total Relevant Market) | Accounts you should pursue now | Funds your GTM strategy |
ICP (Ideal Customer Profile) | Highest-converting subset | Funds your quota |
Think of it this way:
TAM says "the freight industry is worth $800 billion"
TRM says "here are 500 fleets we can win this year"
ICP says "these 100 accounts close fastest"

How Do You Define Your Total Relevant Market?
Start with boundaries. Every boundary should be binary: yes or no, in or out.
The Five Critical Boundaries:
Boundary | What It Defines |
Geographic | Where you can sell and support |
Vertical | Industries with your workflow pain |
Firmographic | Size, revenue, structure |
Technographic | Required integrations |
Trigger-based | Budget cycles, leadership changes |
Clear boundaries create focused outbound GTM strategies.
Sizing Your TRM Like an Operator
Translate boundaries into an account universe using LinkedIn Sales Navigator, ZoomInfo, or your CRM.
Build three scenarios:
Scenario | What It Measures |
Conservative | Bottom quartile conversion |
Base case | Median performance |
Aggressive | Top quartile execution |
Map each to headcount, CAC, and runway.
Prioritizing TRM Segments: Speed, Size, and Story
Not every segment deserves equal attention.
Dimension | What It Measures |
Speed | How fast accounts convert |
Size | Initial ACV and expansion potential |
Story | Will they become reference accounts? |
Focus on segments scoring highest across all three.
Turning Your TRM Into Daily Execution
A TRM document in a strategy deck is worthless. It needs to shape your GTM motion:
Sales: Map territories and quotas to TRM segments Marketing: Build campaigns matched to buying stages Product: Prioritize features for high-value segments Customer Success: Tailor customer experience playbooks by segment RevOps: Track penetration and conversion across revenue operations
Measuring What Matters: TRM Health Metrics
Track these in weekly leadership meetings:
Metric | What It Tells You |
Engagement | % of TRM contacted |
Pipeline | Which segments generate opportunities |
CAC/LTV | Economic viability |
Sales cycle | Where deals stall |
Penetration | % of TRM won |
TRM health is a leading indicator of revenue health.
The Quarterly Shrink Rule
The best GTM strategies get sharper over time.
Every quarter:
Remove segments that didn't convert
Tighten qualifying criteria
Reallocate to winning segments
Add new segments only when current ones are exhausted
Why Do Startups Skip This Step?
Because TRM work feels like constraint.
Founders resist narrowing focus after building for massive markets. Investors push back on targeting 500 accounts instead of 50,000. But from scaling logistics and freight tech startups: constraint creates clarity, and clarity creates conversion.
Companies that figure this out early raise Series B on traction, not TAM promises.

Frequently Asked Questions
What is Total Relevant Market (TRM)?
TRM is the subset of your total addressable market you should actively pursue right now based on product fit, buying triggers, and capacity to win.
How is TRM different from TAM?
TAM measures everyone who could buy your category. TRM identifies who you should target today based on realistic conversion probability.
When should startups define their TRM?
As early as possible, ideally before scaling sales. Companies defining TRM at Seed or Series A avoid spreading resources across too many segments.
How do we prioritize segments within our TRM?
Score on Speed (time to close), Size (ACV and expansion), and Story (reference value). Focus on segments scoring highest across all three.
How often should we update our TRM?
Quarterly at minimum. Fast-moving startups review TRM monthly to incorporate learnings from wins and losses.
Who should own the TRM process?
RevOps and GTM leadership together. TRM requires both strategic thinking and operational execution.
Can our TRM grow over time?
Yes, but it usually shrinks first. The best startups narrow TRM to dominate segments before expanding geographies or verticals.
Should we share our TRM with investors?
Absolutely. Sophisticated investors appreciate precision over inflated TAM. A well-defined TRM with penetration metrics demonstrates strategic discipline.
What if our TRM is too small to hit our revenue goals?
Either expand TRM by loosening one boundary, improve conversion rates, or recalibrate growth expectations to match market reality.
How do we know if a segment should stay in our TRM?
Track engagement, pipeline, and conversion by segment. If a segment consistently underperforms despite adequate outreach, remove it and reallocate resources.
