Segmentation
Segmentation is the practice of dividing your market or customer base into distinct groups based on shared characteristics for more targeted GTM efforts.
Segmentation is the practice of dividing your total addressable market or existing customer base into distinct groups that share common characteristics. The purpose is to tailor your messaging, pricing, sales approach, and product experience to each group rather than treating everyone the same.
The most common segmentation approaches in B2B include: firmographic (company size, industry, geography), behavioral (product usage patterns, engagement level, purchase history), technographic (technology stack, tools in use), and needs-based (specific problems or use cases they care about). Most effective GTM strategies use a combination.
Segmentation directly impacts nearly every GTM decision. Your marketing messages should speak to the specific challenges of each segment. Your sales process should match the buying behavior of each segment — enterprise deals need multi-threaded selling while SMB deals need speed and self-service. Your pricing should reflect the value each segment receives. Your customer success approach should scale differently for high-touch enterprise versus tech-touch SMB.
A practical starting point: segment your existing customers by revenue contribution and analyze what they have in common. You will often find that 80% of your revenue comes from a few distinct profiles. Those profiles become your primary segments for targeting, and everything from ad spend to sales hiring should align with where those segments are.
The mistake most teams make is over-segmenting. Having 20 micro-segments sounds precise but creates operational chaos — you cannot build separate playbooks, content, and campaigns for that many groups. Start with 3-5 segments and refine from there. Using analytics to validate that your segments actually behave differently is essential before building distinct strategies around them.
