Every organization that operates in a community accumulates two kinds of information about the people in it: the records its own systems collect, and the public-record information that lives elsewhere — registry of deeds, assessor databases, voter files, obituary feeds, charitable-trust filings. The friction between these two worlds is where decisions go wrong. Duplicates get mailed twice. Letters arrive addressed to people who have died. Prospects sitting in plain sight in property records never reach the database. Tax classifications get set to last year's number because nobody had time to model the alternatives.
Parcenomics builds the analytical layer that connects the two. Same methodology. Same data infrastructure. Different configurations for the questions different organizations need to answer. Today, two: Donor Intelligence for nonprofits and development offices; Municipal Property Analytics for cities and towns. Built in Massachusetts; the methods travel.
"If your property taxes are too high, this is the tool that finds the new revenue."
The inaugural Parcenomics Fiscal & Civic Profile identifies $1.37 million per year in available revenue for one Berkshire town — backed by parcel-level outreach lists across four compliance streams, the §5C residential exemption, and unused Proposition 2½ capacity. Every finding traces to a specific query against the underlying database. The methodology is portable. Subsequent profiles can be generated in days.
"Your CRM holds what you already know. We build the layer that tells you what's missing."
Every appeal a nonprofit sends begins with a list that isn't quite ready. Active donors live in the CRM. Lapsed donors sit in old exports. Prospects arrive from wealth screens in one format and board referrals in another. And the public-record information that would actually finish the picture — who has died, who has moved, who is sitting on $4M of real estate two towns over — never reaches the database. Preparing each campaign means reconciling these sources by hand, which is why duplicates get mailed twice, widows receive letters addressed to their late spouses, and high-capacity prospects in your service area are never identified at all.
For organizations that have outgrown doing this by hand but haven't reached the scale where an enterprise data platform makes sense, the gap is real and expensive. A single bad send costs more in wasted postage, donor relationship damage, and development-officer time than most boards have ever quantified. Parcenomics closes that gap with the same entity-resolution and public-records infrastructure we apply to municipal work — configured for the questions a development office actually asks.
What we deliver per engagement: a resolved donor universe, a prioritized prospect list drawn from public records in your service area, and a categorized accounting of everything that's broken in your contact data. Three spreadsheets your team can act on the day they arrive.
Records resolved to households in a recent engagement. 548 duplicate records merged. 26 individuals reclassified as the entities they actually represent. 985 couples reordered to modern mail conventions. The list your team thought it had — actually ready.
Prospects sitting in plain sight in property and ownership records — high-capacity households in your service area who never made it to your prospect list. Cross-referenced against your existing universe so you only see who's new.
Deceased-donor matches identified via regional obituary cross-reference in a single engagement. 21 auto-applied at high confidence; 4 surfaced for operator review. Each one was a family that would have received a letter addressed to their late spouse.
CRM data quality findings — every one documented with the specific reason it would not deliver. 1,280 records missing ZIP5. 474 with no usable address at all. The cleanup the development office has been meaning to do, ready to execute.
"We don't need a new tax. We need to collect the ones we already have the right to collect."
Every municipal budget cycle in Massachusetts produces the same conversation. Services cost more. State aid formulas haven't kept pace. Infrastructure is aging. And the one lever that's always available — the residential property tax rate — has been pulled so many times that constituent tolerance is gone.
State aid has not kept pace with municipal costs for a generation. The people who run for Select Board and City Council do so because they believe local government can make a genuine difference — and they are right. The tools to fund that government, without going back to the same overburdened residential taxpayer base, exist right now in your own data.
What has been missing is the analytical infrastructure to use them. Revenue legally owed from non-resident property owners who aren't paying what they owe. A rate structure that may have quietly shifted burden onto working families as commercial values stayed flat. Assessment patterns that ask modest homeowners to carry a disproportionate share. None of this requires new legislation. All of it is addressable with the right analysis.
That is what Parcenomics provides.
Estimated personal property compliance gap in communities with significant non-resident ownership — revenue legally owed, not yet collected.
Assessment drift disproportionately burdens lower-value properties. Quantifying it is the first step to correcting it — before it becomes an abatement problem.
Tax classification and strategic goals are sometimes misaligned. Does your downtown need revitalization? Is the burden on residents sustainable? Do you want to grow your industrial base? We will provide you with detailed scenarios that align your tax levers to the challenges you face.
Massachusetts allows a dizzying array of options for local policy makers. There are exemptions, amounts, splits between classes, and splits like the residential exemption that are within classes. We analyze your specific data and give you real-world options to help you identify what is fair and what best protects your residents.
Every municipal engagement begins with a data access agreement and your assessor's database, your clerk's voter file, or your published recap data — built once, used across all six products. Start with whichever question is most urgent. Nonprofit configurations →
Models every permissible configuration across all five property classes and shows what each means for residential tax burden, commercial taxpayers, and total revenue. When market values shift unevenly — as they have across Massachusetts — the rate structure needs to respond. Your Select Board or City Council votes with data, not last year's number.
Explore Rate ClassificationIdentifies property owners who may be underpaying — or not paying — personal property, and applicable excise obligations taxes. Produces named, ready-to-act deliverables: demand packages, evidence files, and enforcement toolkits your assessor can use immediately.
Explore Compliance ReviewCompares sale prices against assessed values to calculate how the tax burden is actually distributed across property value tiers and neighborhoods. Identifies systematic patterns — modest homes carrying more than their share, high-value properties less — before they compound into abatement waves or DOR compliance problems.
Explore Equity AnalysisModels the RTE under MGL c.59 §5C at every percentage from 5% to 35% — or up to 50% in qualifying seasonal communities. In active use in ~24 municipalities including Boston, Cambridge, Nantucket, and Provincetown. Shows exactly who benefits, who bears increased burden, and how all Massachusetts personal exemptions interact with the levy structure.
Explore Exemption AnalysisAnalyzes your registered voter file and annual street listing to produce a demographic portrait of the people who vote in your community — age distribution, party mix, household density, and registration tenure — benchmarked against Massachusetts and U.S. adult population baselines. The lightest-weight municipal engagement and often the right place to start. Grounds every subsequent policy question in the actual community it will affect.
Explore Voter Profile View Sample →Reconstructs fifteen-plus years of your town's fiscal history from MA Department of Revenue Tax Rate Recapitulations, LA-13 new-growth certifications, and Equalized Valuation data. Quantifies what portion of recent tax-base growth came from new construction versus renovation-and-rebuild of existing properties, tracks tax-rate and levy trajectory in both nominal and inflation-adjusted terms, and places your municipality in peer context. Closes by naming the specific policy decisions under MA General Laws — rate structure, the Residential Tax Exemption, local option revenue mechanisms — that the data informs.
Read the Stockbridge ProfileEvery Parcenomics engagement begins with a modest project launch fee that covers data access setup and delivery of your Revenue Opportunity Assessment — the first and most important document we produce.
The ROA maps your community's probable compliance gap by revenue area, identifies which analytical products apply to your situation, and outlines the specific named deliverables — and the fees tied to each — that make up the rest of the engagement. You see exactly what you're buying before committing to the full scope.
Most clients find that the ROA alone justifies the engagement: it quantifies what's at stake, provides the internal business case for Select Board or City Council approval, and gives your assessor a preview of the findings that are coming. The remaining deliverable fees correspond directly to the recovery roadmap the ROA lays out.
The tools are the same. The data infrastructure is the same. What changes is which question is most urgent — and which combination of products addresses it.
A community of roughly 2,000 parcels where more than half of residential properties are owned by non-residents who spend summers and weekends — but not winters — in town. Personal property tax is self-reported and largely unenforced. The compliance gap across personal property and applicable local excise obligations is invisible to standard assessor workflows — until now.
A city of 25,000+ parcels. A substantial residential base — triple-deckers, modest single-families — that has appreciated sharply since 2020. Commercial and industrial assessed values have not kept pace. The city adopted classification years ago but has not revisited the residential factor with modeled analysis. The median homeowner's effective burden has quietly grown while the rate has nominally stayed flat.
A small city where the budget conversation happens in round numbers and every department has already been cut. The residential tax burden has increased in four of the last five years. Significant industrial property sits on aging assessments. Commercial personal property compliance — equipment, fixtures, inventory — is on the honor system and has never been systematically reviewed.
The first engagement builds your data infrastructure and delivers the baseline findings. The annual review is where sustained value accumulates — new ownership, new non-compliance, market shifts, rate decisions. All of it caught before it compounds.
We operate as an authorized municipal vendor under a standard data access and confidentiality agreement. Your town controls the data. We access what you authorize, handle it under formal confidentiality protections, and return or destroy it at engagement close. Town counsel is welcome to review the agreement before you sign anything.
The first deliverable in every engagement is your Revenue Opportunity Assessment — a scoped projection of what each product will find, tied to the specific deliverable fees that follow. You see the full roadmap before committing to the full engagement.
Standard vendor confidentiality agreement executed at project launch. Your town controls what we access. Town counsel reviews before signing.
First deliverable. Maps your community's probable gap by revenue area, outlines the specific deliverables that follow, and ties each to its corresponding fee. You see the roadmap before committing to the journey.
Each product produces specific named documents — demand packages, evidence files, scenario matrices, board presentations — delivered and billed as completed. No open-ended consulting hours.
Your assessor receives a complete package ready to act on. Optional presentation to your Select Board or City Council. Legal briefing for town counsel at no additional charge.

What makes this different isn't the data. It's what we do with it.
Municipal property data has always existed. Voter rolls, assessor databases, commitment lists, registry of deeds — your community generates all of it. The gap has never been the raw material. The gap has been the analytical infrastructure to turn it into findings that are specific, documented, defensible, and actionable.
Parcenomics draws on advanced data analytics — ratio analysis, regression modeling, geographic disaggregation, statistical outlier detection — applied specifically to the parcel-level data Massachusetts municipalities already collect. That analytical rigor is combined with foundational subject matter expertise in property tax law, municipal finance, and the political realities of local government.
The mission is specific. There is revenue in your tax base that does not come from working-class homeowners, middle-class families, or fixed-income retirees who have lived in their homes for decades and cannot absorb more. It comes from non-resident and seasonal property owners who aren't paying what they owe. From commercial and industrial property that benefits from assessment drift and underenforced classification. From a rate structure that may have shifted burden onto your most vulnerable residential taxpayers without anyone voting for it.
You can fund the government your community needs. You don't have to take it from the people who are already at their limit. That is what Parcenomics is for.
That mission is personal. Parcenomics was founded by Patrick White — an economist, former venture startup CEO, and longtime elected municipal leader whose experience sits at an intersection that essentially doesn't exist elsewhere in this market. His economic training gave him the analytical tools. His time in office gave him the governing reality — sitting in rooms where budget decisions were made under genuine constituent pressure, without adequate data to make them well. He built Parcenomics because those two things together told him exactly what municipalities were missing, and exactly how to package it. These solutions treat compliance, equity, and rate structure not as three separate consulting engagements, but as three dimensions of the same problem — because that's what they are.
We begin with a conversation about your community — its size, its tax base, its budget pressure, and which question is most urgent. No data required on your end to start. A legal and methodological briefing for your governing body or city/town counsel is available before you engage — at no charge.
