Built for people who need to know the market and specific transactions better than anyone else in the room.

Agents, brokerages, investors, developers, lenders, and appraisers use CURVE when knowing your market's data matters makes a difference.

Agents & Brokers

Build real transaction expertise before the client conversation starts.

CURVE helps agents and brokers understand the transaction record behind the market, not just pull a few surface comps. Use it to sharpen your own read, prepare listing strategy, support buyer conversations, explain pricing, and show clients the sales history that actually matters: developer sales, resales, combo sales, appreciation, layouts, price per foot, and comparable activity across the market.

Know the transactions. Explain the market. Earn the trust.
Brokerages

Raise the market standard across the whole firm.

CURVE gives brokerage leadership a shared intelligence layer for the transaction data, neighborhoods, and assets where the firm competes. Agents walk into buyer consults, seller meetings, pricing reviews, and follow-ups with the same verified sale history, analytics, and client-ready reporting. The value is consistency: better-prepared agents, stronger advice, and a brokerage brand that feels more informed than everyone else in the room.

Make better preparation part of the brokerage brand.
Investors

Underwrite the transaction history, not the brochure.

Investors need to know how a unit has actually traded, appreciated, and performed against the surrounding market. CURVE shows sale history, prior basis, appreciation, hold periods, gain/loss outcomes, unit mix, and price-per-foot movement so you can compare opportunities with discipline. Use it before buying, before selling, and while tracking where value is moving.

See the basis. Understand the upside. Avoid the guesswork.
Developers

Understand where your assets sit in the market now.

Developers need more than launch pricing. CURVE shows how comparable transaction sets have absorbed, resold, appreciated, and held value across cycles, price bands, bedroom mixes, and unit sizes. Use it to understand current resale performance, buyer demand, competitive positioning, and where the market is moving before the next pricing, acquisition, financing, or asset-management decision.

Read the market clearly, even when new supply is quiet.
Lenders

Validate collateral with the transaction history behind the asset.

Neighborhood comps miss the transaction-level value drivers inside luxury condo assets. CURVE gives lenders unit-level sale history, prior-sale context, appreciation, financing signals, price-per-foot movement, and resale performance so collateral review is grounded in the exact market the borrower is entering. It helps credit teams understand support, risk, and liquidity before the questions start.

Sharper collateral review. Fewer blind spots.
Appraisers

Build valuations from transaction evidence, not guesswork.

Appraisers need defensible support when asset premiums, floor position, layout, and unit size matter. CURVE surfaces the closed sale history, unit characteristics, prior-sale basis, appreciation, and comparable transaction activity needed to explain adjustments with less guesswork. It is built for valuation work where the wrong comp set can distort the entire conclusion.

Defend the value with better underlying evidence.

The premier data, analytics, and reporting platform every professional needs

CURVE shows what actually happened in the market, cleans the fragmented and scattered transaction context, and turns verified data into analysis you can leverage with clients.

Full-market coverage
×MLS sold data

MLS only shows what was listed there. Many luxury condos, developer closings, private resales, off-market trades, package deals, and high-end transfers never hit the MLS.

CURVE

CURVE pulls every sale, deed event, unit record, and source-backed transaction from the Registry of Deeds, assessor database, and other verified sources to show the full market, not just the MLS-visible slice.

Comp-quality sale context
×MLS sold data

MLS can tell you when some units are sold. It cannot tell you whether the sale was developer inventory, a true resale, a combo residence, a restricted transfer, or a deed event that should not be treated as a normal comp.

CURVE

CURVE classifies the sale before you use it: developer sale vs resale, combo-sale logic and history, deed context, prior-sale basis, appreciation metrics, and transfer quality so the wrong record does not distort your analysis.

Unit lineage over time
×MLS sold data

MLS shows you basic information and listing remarks, but it is still a point-in-time listing record. MLS does not show how the unit has traded over time or whether its last sale actually supports today’s value.

CURVE

CURVE connects the unit’s sale lineage: prior prices, hold period, appreciation, gain/loss, cash vs mortgage, resale order, and comparable activity across the sales data so you can explain why the unit should command its number.

Defensible market logic
×MLS sold data

MLS forces agents to improvise the market read: download comps, copy screenshots, build a CMA, remember property quirks, and manually explain why one sale matters more than another.

CURVE

CURVE turns cleaned records into market logic: appreciation, gain vs loss, bedroom mix, sqft bands, price ranges, sale cycles, and transaction performance that make pricing, buyer advice, and seller conversations actually defensible.

Client-ready output
×MLS sold data

MLS gives you raw records. You then spend hours piecing together comps, screenshots, notes, and proposals that may still be based on an incomplete view of the transaction history and market.

CURVE

CURVE turns in-depth data analysis into client-ready assets: interactive reports, unit sale histories, custom data feeds, tracking updates, and shareable links that make your expertise visible before you even start explaining.

The point is simple: CURVE gives you the data, analysis, and reports that MLS cannot.
