Most professionals have contacts scattered across LinkedIn, their phone, email threads, and a stack of business cards they'll never look at again. The first step in building a personal CRM isn't choosing software — it's designing your contact architecture: the information you capture about each person and how you organize it.
The TIER System for Contact Classification
Not every contact deserves the same attention. The TIER system ranks your contacts by strategic value:
Tier 1 — Inner Circle (10-15 people): Decision-makers who directly influence your career trajectory. Your current boss's boss, a former mentor at a target company, two or three industry connectors who know everyone. These contacts get monthly touchpoints and real relationship investment.
Tier 2 — Active Network (40-60 people): People in adjacent roles, hiring managers at companies you'd consider, former colleagues doing interesting work. Quarterly touchpoints. You should be able to name their current role and one recent project.
Tier 3 — Extended Web (150+ people): Conference connections, former classmates, LinkedIn contacts with potential value. Semi-annual check-ins. You need enough context to make each interaction feel personal, not transactional.
According to sociologist Mark Granovetter's research, it's actually these "weak ties" — your Tier 3 — that most often surface new job opportunities. The person you met once at a conference in 2019 works at a company that just posted your dream role. But only if you've maintained enough connection that they'll take your call.
What Data to Capture (and What to Skip)
For each contact, you need exactly seven fields: name, company, role, how you met, date of last contact, one personal detail, and one professional detail. That's it. More than that and you'll never maintain it. Less than that and you can't personalize your outreach.
The personal detail is critical. "Has two kids" or "runs marathons" or "lives in Austin" gives you a hook that makes reconnection feel natural. Without it, your messages read like cold outreach — even to people you've known for years.
Tools That Actually Work
You don't need Salesforce. For most professionals, a well-structured spreadsheet with 7 columns outperforms expensive CRM tools. Column headers: Name | Company | Role | Met Via | Last Contact | Personal Note | Professional Note. Sort by "Last Contact" weekly to see who's going cold. That single workflow will transform your networking within 30 days.
If you want something more robust, Notion databases or the free tier of HubSpot CRM work well. The tool matters far less than the discipline of capturing data within 24 hours of every meaningful interaction.
