Why Choose Plotbook?

Property-Cluster Donor Discovery

Plotbook's map reveals clusters of high-value homeowners near your institution. Discover potential donors by neighborhood instead of screening only your existing database.

Wealth Estimation with Property Evidence

Plotbook anchors wealth estimates in real property data — assessed values, parcel size, neighborhood context. iWave's capacity ratings are modeled without property-level transparency.

Verified Business Contacts

Plotbook delivers verified business emails and phone numbers via Apollo and RocketReach. iWave's contact data is limited and designed for screening, not direct outreach.

iWave provides donor propensity scores, giving history from IRS 990s and SEC filings, philanthropic affinity ratings, and deep CRM integrations with Blackbaud and Raiser's Edge. It's purpose-built for nonprofit wealth screening at scale.
Plotbook offers an interactive property map for visual discovery, AI-powered live owner research, property-to-owner linkage from a single click, and verified business contacts from Apollo and RocketReach. It finds prospects iWave can't — because iWave only screens people already in your database.
Absolutely. Development officers use Plotbook to identify high-value homeowners near their campus or event venues, research their wealth profiles with AI, and get verified contact details — all before the first outreach.
Plotbook starts at $79/month with no annual contract. iWave uses enterprise pricing with custom quotes, typically requiring annual commitments. Plotbook is accessible to smaller nonprofits and individual fundraisers who can't justify enterprise wealth screening costs.
