Methodology

How we collect, validate, and present startup data on Startup360.

Data Sources

All data on Startup360 is sourced from publicly available information, including:

  • Official company press releases and blog posts
  • SEC filings, EDGAR disclosures, and regulatory documents
  • Verified funding announcements (Crunchbase, PitchBook, Bloomberg)
  • Founder and executive interviews in major publications
  • Community-submitted corrections reviewed by our team

We do not publish data obtained through NDAs, confidential sources, or unofficial sites.

ARR & Valuation Figures

Annual Recurring Revenue (ARR) figures are sourced from company disclosures or credible third-party reporting. Where exact figures are unavailable, we use the most recent disclosed range and note any estimation.

Valuations reflect the post-money valuation at the time of the most recent disclosed funding round. Valuations are not updated in real time and may lag the current market value.

Val/ARR multiples are computed as Valuation ÷ ARR and rounded to one decimal place.

AI Top 10 Selection Criteria

The AI Top 10 list is published quarterly and reflects our editorial judgment on the most promising US-headquartered generative AI companies. Selection weighs four primary factors:

Growth Trajectory
YoY ARR growth rate and recent acceleration or deceleration trends.
Capital Efficiency
Revenue per employee and ARR relative to total funding raised.
Product Differentiation
Defensibility of technology, moat depth, and competitive positioning.
Market Timing
Alignment between product and a large, fast-growing addressable market.

Rankings are not investment advice. Companies are not paid to appear on the list.

Update Cadence

The company database is updated on a rolling basis as new information becomes available. The AI Top 10 list is refreshed every quarter (Q1, Q2, Q3, Q4). ARR history data points are added when companies publicly disclose new figures.

Last dataset update: March 2026
