iWave Alternative for Billionaire Prospect Research

The best iWave alternative depends on whom you screen. For a broad donor file, compare DonorSearch, WealthEngine and Windfall against iWave. For prospects worth $1B or more, BillionaireList offers every living billionaire ranked with a dated, sourced net worth, filters, XLSX and CSV exports, and alerts on changes. It covers billionaire research alongside your screening platform, with Pro at $49 a month or $24 a month billed yearly.

That distinction matters to university advancement directors, hospital fundraisers and prospect researchers at large nonprofits. Replacing donor screening and finding an affordable way to follow your wealthiest prospects are different purchasing decisions. Wealth advisers face a similar choice when their research concentrates on billionaire clients rather than a broad household file.

Why teams look for an iWave alternative

iWave belongs to Kindsight and provides nonprofit prospect research and wealth screening. Its breadth can be useful, but buyers should match the contract to the work their team actually does. Common reasons to compare vendors include:

• Per-user pricing. G2 lists a starter tier around $4,150 per user per year. iWave does not publish vendor pricing, so treat that listing as a budgeting reference and request a quote for your team.
• Screen and profile caps. The G2 listing includes about 1,500 screens and 750 live profiles. Capterra reviewers mention cost and per-profile limits as pain points. Ask which actions count toward each allowance before estimating your research workload.
• Top-of-pyramid needs. After screening the donor file, a principal gifts officer may concentrate on a handful of billionaires. Following their wealth estimates and changes is a narrower job than repeatedly screening the full database.
• Sources for briefing memos. A capacity score helps prioritize research. A meeting brief also needs the publisher and date behind a wealth estimate, so the gift officer can explain what the figure represents.

iWave alternatives compared

Compare coverage before price. The products below serve overlapping needs, but a billionaire ranking cannot replace a donor screening platform. Quote-only vendors require a direct proposal; the G2 figure is a third-party listing rather than an official iWave price.

DonorSearch for philanthropy research

DonorSearch is a natural shortlist option when giving history matters to your qualification process. Ask for a demonstration using prospects your researchers already know, then compare how easily they can assess philanthropic records. Pricing is quote only. Test the research workflow and requested CRM connection rather than assuming either vendor fits your advancement operation.

WealthEngine for broader wealth screening

WealthEngine belongs on the shortlist when your assignment is screening the donor file or researching a broader client population. It belongs to Altrata and is quote only. Our WealthEngine alternative comparison explains the distinction between broad screening and focused billionaire research. Request terms for your own file size and research team.

Windfall for household wealth research

Windfall is worth evaluating when household wealth is central to identifying prospects in an existing database. It is quote only. During a demo, examine how household matches would fit your donor records and how researchers would resolve uncertain matches. Choose based on the research your file requires, with costs and access allowances confirmed in writing.

Wealth-X for ultra high net worth profiles

Wealth-X suits buyers looking for ultra high net worth profile research beyond billionaires. It is quote only and belongs to Altrata, as do WealthEngine, RelSci and BoardEx. These are distinct products under the same owner. Read our Wealth-X alternative comparison if detailed profiles are part of your vendor brief.

BillionaireList for the billionaire prospects you track

BillionaireList fits a focused research assignment. Filter the ranking, follow changes and export the relevant prospects with dated, sourced net worth figures. Pro includes 2,000 export rows a month. Data costs $199 a month and includes 25,000 rows, history and API access. Enterprise is $499 a month. A confirmed account gets one 25-row sample export.

Coverage stops at billionaires. There are no capacity scores, contact data or CRM screening of a whole database. If you need a list of ultra high net worth individuals, distinguish billionaire coverage from the wider wealth segment before buying. Forbes and Bloomberg rankings are free to read with no export, so they also suit occasional manual lookups.

When iWave is still the right choice

Keep iWave on the shortlist when your main task is bulk screening of a donor file. Its capacity and affinity scores, philanthropic giving records and CRM integrations such as Raiser's Edge and Salesforce serve a broader advancement workflow. Those capabilities matter when researchers must qualify prospects throughout the database, including people below the billionaire threshold.

For a university, hospital or large nonprofit, the value depends on how much of that workflow the team uses. Review the tasks researchers perform, the profiles they need and the role of CRM integration. A lower subscription price does not help if your replacement leaves the central screening assignment unfinished.

A practical way to decide is a short side by side trial. Pick twenty prospects your team already knows well, including a few at the very top of the wealth range, and compare what each tool returns for them: how current the figures are, whether every estimate carries a date and a source, and how long it takes to turn the result into a briefing. Write down which tasks still need the screening platform after the trial. That list, not the price page, tells you whether to replace iWave, keep it, or run both for different jobs.

How a major gifts team uses billionaire data alongside screening

• Screen the donor file. Use iWave or a comparable platform to identify candidates across the database. Review matches and combine screening results with your institution's relationship notes.
• Identify the billionaire prospects. Keep the broad qualification work in your screening workflow. Track the handful of billionaire prospects separately using dated net worth figures, source references and alerts on changes.
• Prepare the briefing memo. Use the billionaires list builder with XLSX and CSV downloads to export the relevant records. Record the estimate date and source in the memo, and explain that net worth does not establish giving intent or available cash.
• Add philanthropic context. Review giving records and your relationship history before suggesting an approach. Our guide to billionaire philanthropy and giving provides context for that research. A wealth alert is a reason to review the brief, not evidence that a gift is imminent.

When a gift officer next needs to reach a foundation's or family office's staff, identify the appropriate role through the organization's public information, then find and verify a work email address. BillionaireList does not provide contact data. Keep the contact research and relationship notes in your existing outreach process.

What is the best alternative to iWave?

For broad donor screening, compare DonorSearch, WealthEngine and Windfall with iWave using your own file and research requirements. For billionaire prospects, BillionaireList provides dated, sourced net worth figures, filters, exports and alerts. The best fit depends on whether you need database screening or focused research on people worth $1B or more.

How much does iWave cost?

iWave does not publish vendor pricing. A starter tier listed on G2 is around $4,150 per user per year, with caps of about 1,500 screens and 750 live profiles. Treat those figures as third-party guidance and ask iWave for a quote confirming seats, allowances and the features your team needs.

Is iWave worth the money?

iWave can be worth the money when your team uses bulk donor screening, capacity and affinity scores, philanthropic records and CRM integrations. If the main task is tracking billionaire prospects, a narrower tool may fit the budget better. Compare the actual research assignment and access limits before deciding on renewal.

What is the difference between iWave and DonorSearch?

Both serve nonprofit prospect research and screening. iWave combines wealth screening, capacity and affinity scores, giving records and CRM integrations. DonorSearch focuses on donor research using philanthropic giving history and wealth indicators. Compare them on your own prospects, research workflow and quoted terms rather than assuming either is a universal replacement.

Can I use billionaire data for major gift prospect research?

Yes. Billionaire data helps researchers identify prospects, cite dated wealth estimates and monitor changes before cultivation meetings. It cannot establish affinity, willingness to give or available cash. Pair it with philanthropic records and your institution's relationship knowledge. BillionaireList covers only billionaires and supplies neither capacity scores nor contact data.

Match the purchase to the prospects you actually research. Compare BillionaireList plans and export allowances, then use the billionaire list builder to check coverage for your shortlist. Confirm an account for the one 25-row sample export and assess whether its dated, sourced figures fit your briefing memos.
