What to look for if coalition-building is the priority

When evaluating firms, ask whether they have:

• Demonstrated coalition wins across nonprofits, business groups, labor, or public agencies
• Community organizer-style capabilities rather than only media relations
• Local partner networks and bilingual/culturally competent outreach
• Facilitation experience for convenings, listening sessions, and alliance management
• Field outreach capacity: canvassing, phone/text banks, events, ambassador programs
• Issue credibility in your sector (energy, infrastructure, health, housing, etc.)
