Unlock actionable insights from NYC's public building data. Track permits and filings, follow property values and sales, and see the housing and landmark record behind every address, across the architects, engineers, contractors and owners who shape the city.
Dashboards
Each dashboard answers a question your team asks every week: who is building, what is being filed, which buildings need attention. Every record is tied to its building, so any answer opens into the full story in Building Profile.
Building profile
BetaSearch any NYC address and get one page that tells you what the building is, what it is worth, what is happening there and what needs attention. Records from across city agencies come together on the building, so you can size up a property in minutes instead of hours in agency portals.

Compliance & sustainability
Facade inspection (FISP) reports by cycle and status, next to every graded building's ENERGY STAR score and letter grade. See which facades are unsafe and which buildings score low, and act before a violation or a failing grade turns into a costly repair or a fine.

Vela Analyst
BetaAsk about NYC buildings, permits and licenses in plain English. Vela queries Velabyte's datasets for you and shows its work:
Answers, not spreadsheets
A plain-language summary that names the datasets behind it, so you know what to trust.
Dig deeper on demand
Open a chart or the full table when you need it, and skip it when you don't.
See the building, not just the number
Every building and license in the answer is identified, and any building opens in 3D for free.
Keep the thread going
Vela suggests the next question, so one answer leads to the next insight.

Data quality
Public records are messy. Every source is collected daily and passes through three layers, each with one job, before a number reaches you.
Layer 1
Every source is typed, cleaned and normalized into one galaxy schema: shared dimensions for buildings, lots and licenses, and a fact table for each kind of record, from permits and violations to sales and complaints. History is kept, so any record can be seen as it was.
26 fact · 77 dimension tables
Layer 2
Summaries by building, contractor, neighborhood, year and month are computed ahead of time, so questions are answered in seconds instead of rescanning millions of records.
44 summary tables
Layer 3
Tables shaped for each dashboard's trends, maps and drill-downs, and the governed ground truth behind Vela Analyst's plain-English answers.

Data engineering & architecture
We design and build custom data platforms for complex operations, with deep expertise in the built world: pipelines that integrate every source, a governed warehouse you can trust, and data ready for business intelligence and AI.
Transactional and analytical systems designed around your business and built to scale: normalized operational databases that stay fast and consistent, and a galaxy schema for analytics whose dimensions time-travel by design, with no extra servers.
Production pipelines connect every API, database and file over the protocol that fits, from REST to gRPC and server-sent events. Data moves in batch, incrementally or in real time, orchestrated and monitored end to end. Transformations are written in portable ANSI SQL, extended where it adds value, with Python and Rust for procedural logic.
Quality built in, not bolted on. Normalization is embedded in your operational processes, so data is validated at the point of entry, duplicates and entities resolve to a single record, and governance comes by default: every number traces back to its source.
Ask your data anything. Clean, modeled and documented tables give AI analysts the context to answer accurately, with sources you can check, and the same data powers your dashboards and self-serve BI. It is the foundation behind Vela Analyst.
Data quality and database design, transactional and analytical, are what we do every day. The same discipline runs every Velabyte dashboard: decades of messy public filings typed, merged across systems and linked to the buildings they describe. We bring it to your data.
Custom applications
We build the web applications your teams and clients work in, from client portals and operational tools to interactive 3D maps: fast, secure, and built on the same platform as your data.
Purpose-built render engines, from hybrid GPU/CPU 2D to full 3D on the GPU, compiled to WebAssembly. Maps, models and charts run at near-native speed in any modern browser and stay smooth on large datasets. Nothing to install.
Every exchange between browser and server is end-to-end encrypted with the Olm ratchet protocol, the cryptography behind secure messaging, on top of HTTPS. Data is sent only as it is needed, in compressed columnar form, so large datasets stay light on your mobile plan.
Rust on the server and in the browser: one type-safe codebase, so features ship faster and whole classes of bugs never reach production. It runs as serverless microservices that scale with demand and down to zero when idle, so no servers sit waiting on traffic: one of the ways we keep costs low.
Every chart follows Edward Tufte's principles of data visualization: high data-ink, no chartjunk and honest scales, so the data speaks for itself. Interfaces are styled with Tailwind CSS, the best-in-class utility-first framework, compiled ahead of time into one lean stylesheet: little overhead, and no Node.js servers to run.
Fast by design, secure by default, and built to grow with you.
