NYC Startup Funding Index — Methodology

What This Dataset Is

The AlleyWatch NYC Startup Funding Index is a structured database of individual equity funding rounds raised by New York City-based technology-enabled startups. The dataset spans 2010 through the present and is updated on a continuous basis as new rounds are identified and verified.

The Index is designed to serve as the canonical reference for NYC startup funding activity — supporting journalism, investor research, founder benchmarking, and academic study. Every round in the dataset has been individually reviewed and classified by the AlleyWatch Data Team.

Geographic Scope

The dataset covers companies that were headquartered in New York City at the time of their funding round. This includes all five boroughs: Manhattan, Brooklyn, Queens, the Bronx, and Staten Island. Companies that subsequently relocated outside of NYC may still appear in the dataset for rounds that occurred while they were NYC-based.

Geographic classification is based on the company's primary operating address at the time of the announcement. Remote-first companies with nominal NYC addresses are evaluated on a case-by-case basis and are generally excluded unless the company has a meaningful operational presence in the city.

Industry Scope

The dataset focuses on technology-enabled companies. This includes software, fintech, healthtech, AI, enterprise, e-commerce, media technology, clean energy technology, and other sectors where technology is a core component of the business model. Traditional businesses that happen to use technology are generally excluded.

The AlleyWatch Data Team applies consistent editorial judgment to industry classification. Edge cases are reviewed individually. The goal is to capture the NYC innovation economy accurately rather than maximize count.

Round Classification

Each funding round is assigned a normalized stage classification based on the round type reported and the amount raised. The classification system uses the following hierarchy:

What Is Excluded

The following round types are excluded from all aggregations and public-facing totals:

• –Debt rounds — venture debt, convertible notes held as debt instruments, revenue-based financing, and credit facilities are excluded. Only equity and equity-equivalent instruments are included.
• –Grants — government grants, non-dilutive awards, and prize money are excluded.
• –Non-technology companies — traditional businesses, real estate operating companies, and businesses without a technology component are excluded.
• –Non-NYC companies — companies headquartered outside NYC at the time of the round are excluded even if the founders are based in the city.
• –Duplicate rounds — when the same round is reported by multiple sources with different dates or amounts, the AlleyWatch Data Team reconciles these into a single canonical record.

Data Sources

The dataset is compiled from multiple sources and reconciled into a single canonical record per funding event. Primary sources include AlleyWatch monthly funding reports (published since 2013), company press releases, SEC filings, and direct company outreach.

The AlleyWatch monthly funding report — published each month since 2013 — serves as the authoritative reconciliation layer. Daily updates are added as rounds are identified throughout the month and then reconciled against the monthly report upon publication.

Reconciliation Process

When a funding round appears in multiple sources with conflicting data — different announced amounts, different dates, or different stage labels — the AlleyWatch Data Team applies a structured reconciliation process. The authoritative monthly AlleyWatch report takes precedence over daily imports. Manually reviewed and verified records take precedence over automated ingestion.

Potential duplicate rounds are detected using a weighted scoring system that considers company name similarity, round amount, announcement date proximity, stage label alignment, and investor overlap. Likely duplicates are flagged for human review before being merged into a single canonical record.

Coverage and Limitations

The dataset is comprehensive but not exhaustive. Not all funding rounds are publicly announced, and some announced rounds may not include full details such as exact amounts or investor names. Rounds where the amount was not publicly disclosed are excluded from dollar-denominated aggregations but may appear in deal count totals.

Coverage depth varies by year. Data from 2010–2014 is less complete than data from 2015 onward, reflecting the maturation of startup data infrastructure during that period. Data from 2018 onward is considered highly comprehensive for the NYC market.

Investor data is based on public announcements and may not reflect the complete investor syndicate for every round. Lead investor designation is included where available but is not always disclosed publicly.
