Is Plotbook a Windfall alternative?

Only if what you want from Windfall is wealth figures on a small number of people you are researching individually. As a data layer for valuing a file at scale, Plotbook is not an alternative: there is no upload, no batch scoring, no weekly refresh, and no data delivery into your systems beyond CSV export on Professional and Enterprise.

Why does Plotbook show ranges when Windfall shows exact figures?

Because both are estimates, and a range says so. A single figure sorts more cleanly, which is a real advantage for screening a large file, but it carries no signal about how confident the model was. Plotbook shows four ranges, net worth, income, investible assets, and total assets, plus a separate confidence score about the identification and the tier the research run reached. The design goal is that a weak answer looks weak rather than looking like a number.

Which set of wealth figures is more accurate?

They are not measured against the same thing, so nobody can answer that honestly, including us. Windfall models a population continuously with weekly refresh, which gives it coverage and currency we do not have. Plotbook reasons over what one specific research run found about one person, including the parcel, other recorded properties, employer and role, and residential records, which gives it a visible trail we can open and they cannot. If accuracy at file scale is the question, their method is built for it. If you want to check a single answer, ours is.

Can Plotbook enrich a list of households I already have?

Not as a batch. There is no upload. You would be researching each one individually at 25 credits a run, which is the wrong economics for a list of any size. Plotbook is built to produce records from geography rather than to improve records you already hold.

Does Plotbook refresh its data automatically?

No, and this is a genuine limitation against Windfall's weekly cadence. A Plotbook profile is a snapshot of what a research run found at the time it ran. Re-running research on the same property returns the saved profile instantly rather than redoing the work, and there is a flag to force a fresh run when you want current information. Parcel data itself follows county publication cadence, which is weeks after a closing rather than minutes.

What does Windfall cost compared to Plotbook?

Windfall prices by quote and does not publish a rate card, so we will not print a figure for them. Plotbook publishes its own: $79 per month for Starter, $199 for Professional, $499 for Enterprise, with 750, 2,500, and 8,000 credits, and roughly 20% off billed annually. The meaningful difference is shape rather than number, since one is a data subscription sized to your file and the other is a seat with credits.

Plotbook vs Windfall

Windfall gives you a number. You still need the name

Windfall models household net worth as a precise figure rather than a band and refreshes its data weekly. That is a serious data operation and their presentation is cleaner than ours: a single number is easier to sort a file by than a range. But every one of those numbers is attached to a household you have to bring them. If your problem is that you do not have the households yet, a better estimate does not help. That is the gap Plotbook is built for.

The short answer

Enrichment, or discovery

Windfall is an enrichment and screening layer: it makes records you already hold more useful, at population scale and on a weekly cadence. Plotbook is a discovery tool: it produces records that do not exist yet, one property at a time. Neither substitutes for the other, and the honest test is which end of the pipeline is currently your constraint. If you have plenty of names and poor information about them, Windfall. If you have good information about too few people, Plotbook.

Plotbook

Pick Plotbook if you need new names

You have a territory rather than a file, and no records to enrich yet.
You want to see wealth geographically, parcel by parcel, rather than as a scored column.
You need the person behind an LLC or trust-held deed, which is an identity problem rather than a scoring one.
You want to see how an estimate was reached, source by source, before you act on it.
You are an individual or a small team buying on a card, not negotiating a data contract.

Windfall

Pick Windfall if you already have the records

You hold a substantial file of households and need every one valued.
A precise sortable figure suits your workflow better than a range.
Weekly refresh across the population matters to how you operate.
You want net worth delivered into your CRM or data warehouse rather than read in an app.
You are screening at a scale where per-prospect research is not a sensible unit of work.

Neutral ground

What each product actually is

Both get called wealth intelligence. One is a data product, the other is a research tool, and that distinction explains almost every difference below.

Wealth output: Four ranges, net worth, income, investible assets, and total assets, with a confidence score
Refresh: Per research run. Nothing updates on its own.
Scale: One prospect per run, at 25 credits
Pricing: $79 to $499 per month, published, self-serve

Windfall

A people intelligence data provider modeling precise household net worth, refreshed weekly and delivered into customer systems.

Precision and honesty

A precise figure is still an estimate

Windfall's presentation is genuinely better for sorting: a column of single numbers ranks cleanly and a column of ranges does not. If your workflow is ordering ten thousand households by wealth, that difference is real and it is in their favour.

What a point figure does not carry is uncertainty. An $11.8M and an $11.8M that the model is far less sure about look identical in a spreadsheet. Plotbook goes the other way on purpose. Every wealth figure is a range, there are four of them, net worth, income, investible assets, and total assets, and each profile carries a separate confidence score about the identification itself, plus the tier the research run actually reached. A thin answer is meant to look thin.

The other difference is that ours is checkable. Every run keeps its timeline: which registries were queried, which county records were read, which contact databases returned what, and which sources corroborated the identity. If a range looks wrong, you can open the trail and see why the model thought otherwise. That is a different kind of trust from a well-built proprietary model, and for a fiduciary putting a number in front of a client, we would argue it is the more useful kind.

The upstream problem

Enrichment cannot fix an empty list

Windfall's model needs a household to value. That is not a criticism, it is what an enrichment layer is, and it works extremely well when records exist. But it makes the product useless for the specific problem of not having any records, which is the position most independent advisors and small development shops are actually in.

Plotbook starts one step earlier. Nationwide parcel data from Regrid, covering 150M+ parcels, colored across six assessed-value bands, with deed owner names printed on parcels once you zoom past 16. You are looking at households before anyone has put them in a file, sorted by the most visible durable wealth signal in the country. Reading the map costs no credits on any plan, including the trial.

From there the research agent converts a parcel into a person: deterministic classification of the owner entity first, then reverse address lookups, then registry, county record, and contact database work as the entity type demands. What comes out is a named person with contacts, four wealth ranges, and the trail that produced them. That record is the thing Windfall would have needed you to already have.

The other side

What Windfall does better than us

On the data itself, Windfall is operating at a scale and a cadence we are not, and pretending otherwise would be silly.

Population coverage

A household-level dataset refreshed weekly and designed for screening at scale. Plotbook knows nothing about a household until you pay for a research run on one, and then it knows about exactly that one.

Weekly refresh

Their figures are maintained on a weekly cadence. Ours are a snapshot of the moment a run finished, and nothing updates on its own afterwards. For any use where currency matters, that is a decisive difference.

A single sortable figure

Ranking a large file by a precise number is straightforward. Ranking it by four ranges is not. If your workflow is sorting at scale, their presentation is the better one and we would not argue.

Unlimited screening

Their model lets customers screen records without paying per lookup. Plotbook charges 25 credits per research run, which is a poor fit for volume work and a fine fit for considered work.

Delivery into your stack

CRM integrations and data-platform delivery mean the figure lands where your systems already read from. Plotbook has CSV export, on Professional and Enterprise only.

Data science maturity

A well-funded team building wealth models at population scale, with the validation work that implies. Our estimates come from a language model reasoning over what one research run found, which is a narrower and less battle-tested method.

If you have a file and need it valued, Windfall is the better instrument by a clear margin. Plotbook is for the step before that file exists, and for the cases where you want to see the reasoning rather than trust the model.

Running both

Find, then value

The composition is straightforward, because they sit at different points in the pipeline. Plotbook manufactures records from geography. Windfall values records at scale. A team running both would prospect the territory in Plotbook and pipe the resulting households into whatever they already screen with.

The seam is CSV export, which carries the parcel, the four wealth ranges, the confidence score, and the research summary. There is no direct integration with Windfall or with any CRM, and export requires Professional or Enterprise. On the $79 Starter plan you can research and keep profiles but not export them, which is worth knowing before you build a process around it.

One genuine benefit of running both: two independent estimates of the same household, produced by different methods from different inputs. When they agree, that is a stronger signal than either alone. When they disagree, Plotbook's research trail is the one you can open to find out why.

What it costs

Priced per answer

Plotbook bills a subscription plus credits, and credits are spent only when a paid source is called for you. That is a different economic shape from a data subscription, and it suits considered work rather than volume.

Browsing the map and filtering by value band: included
Opening a parcel Plotbook has not seen before: 1 credits
Instant owner lookup on a residential address: 15 credits
Full research run on an entity-held deed: 25 credits
Keeping the result as a profile: 10 credits
Exporting to CSV: 5 credits

Professional is $199 per month for 2,500 credits, or $159 per month billed annually, covering roughly 60 full research runs plus the map work around them. New subscribers get 7 days and 100 credits. The trial takes a card and converts on day 8, and we email you before it does.
