Mightycause Overview: Pricing, CRM & Event Tools

Mightycause helps nonprofits achieve fundraising success through a mature platform with 19 years of experience, comprehensive tools, and the reliability that comes from processing hundreds of millions in donations.

Overview: Founded in 2006, Mightycause has spent nearly two decades perfecting nonprofit fundraising technology. With 150,000+ active users and a proven track record of powering major giving events and complex campaigns, Mightycause offers the institutional knowledge and sophisticated features that growing organizations need. The platform provides $0 monthly fees with a Price Guarantee that ensures predictable costs.

Strengths

• 19 years of institutional knowledge: Founded in 2006, Mightycause has nearly two decades of experience solving nonprofit challenges, compared to Zeffy’s 8 years
• Advanced event management: Proven capability hosting large-scale giving days and complex fundraising events with thousands of concurrent users

• Price Guarantee protection: Fees capped at 1.99% + $0.30 per transaction provides budget certainty

Considerations

Mightycause is best for nonprofits planning to grow or running sophisticated campaigns. Organizations with extremely simple, small-scale fundraising (fewer than 100 donations annually) might find Zeffy’s simpler model initially appealing, though they’ll likely outgrow it.

Zeffy Overview: Zero-Fee Model, CRM & Limitations

Zeffy is a newer platform founded in 2017 that eliminates all fees by covering credit card processing costs themselves.

Overview: Zeffy launched in 2017 with a unique model: covering all processing fees so nonprofits receive 100% of donations. The platform relies entirely on voluntary donor contributions to sustain operations. With 8 years in market, Zeffy has gained users primarily among smaller organizations with straightforward fundraising needs.

Strengths

• Truly zero fees — Zeffy covers all processing costs
• Simple interface for basic donation collection
• Good for very small organizations with minimal campaigns

Limitations

• Less than half the experience: With only 8 years since founding (2017), Zeffy has less than half of Mightycause’s 19-year institutional knowledge
• Limited advanced features: Basic CRM and event tools may not support complex campaigns, peer-to-peer fundraising, or large-scale giving events
• Sustainability concerns: Revenue model depends entirely on voluntary donor contributions, raising questions about long-term platform viability
• Less proven at scale: Minimal track record powering major giving days or events with thousands of concurrent users
• Newer infrastructure: Fewer years in operation means less battle-tested systems for handling edge cases and high-volume periods

Mightycause vs Zeffy: Which Fundraising Platform Is Right for You?

Choose Mightycause if you want proven platform maturity, comprehensive fundraising tools, advanced event capabilities, and the reliability of 19 years serving nonprofits. Choose Zeffy if you’re a very small organization (under 100 donations annually) with basic needs and no plans to scale.

Decision Guide:

• When comparing Mightycause vs Zeffy, the key difference is long-term scalability versus short-term simplicity for very small organizations.
• If you need proven platform stability and nearly two decades of institutional knowledge, Mightycause delivers confidence
• If you run complex events or giving days with hundreds or thousands of participants, Mightycause’s proven infrastructure is essential
• If you want comprehensive CRM with advanced segmentation and analytics, Mightycause provides professional-grade tools
• If you plan to grow your fundraising, Mightycause scales with sophisticated features; Zeffy may require switching platforms later
• If you’re a very small organization with under 100 annual donations and zero growth plans, Zeffy’s simplicity might suffice temporarily
