Crunchbase Funding Round Search by Investor, Stage and Date

Search company financing rounds using optional company, investor, lead_investor, category and location filters. Company accepts an organization permalink, UUID or Crunchbase organization URL; investor and lead_investor accept company or person identifiers or Crunchbase URLs. Industry and location filters accept a name, permalink or UUID. announced_after and announced_before are inclusive dates in YYYY-MM-DD format. min_amount and max_amount are nonnegative USD thresholds; min_investors must be at least 1. funding_stage describes the company that raised capital, whereas round_type selects the financing event and can contain comma-separated types. equity_only is a string accepting true or false, with true excluding debt and grants. The documented default sort is announced. Both announced and amount return one page; rank supports deeper pagination. page defaults to 1 and accepts 1 through 100, but this range does not guarantee that 100 pages exist or override sort-specific limits. No direct probe is recorded for this operation. The supplied source example is partial and unverified: it shows count, current_page and an items array, but does not establish the complete response envelope. A complete example item includes id, uuid, name, link, round_type, rank, company, company_diversity_spotlights, company_funding_total, investors, investors_count, lead_investors, amount, target_amount, announced_on, closed_on, is_equity, pre_money_valuation, post_money_valuation and short_description. The company reference includes id, uuid, name, link, type and image; lead_investors contains identity references with id, uuid, name, link and type. The investors list is empty in that example, so its member schema is not established. Financial values, dates, is_equity and short_description are null in the example. Preserve unknowns rather than treating them as zero, and do not interpret search results or relationship lists as complete deal-flow coverage.

Use Cases

Build an investment-thesis watchlist for an industry and location using an inclusive announcement window and selected financing round types.
Find recorded financing events involving a target investor, then use lead_investor when a lead role is essential to the research question.
Screen available deal records within a disclosed USD amount band and above a chosen investor-count threshold, without claiming complete market coverage.
Research a named company's financing events by funding stage while keeping undisclosed amounts and valuations distinct from zero.
Prepare a ranked diligence queue with sort=rank instead of expecting additional result pages from announced or amount ordering.

Frequently asked questions

How do funding_stage and round_type differ?

funding_stage describes the company that raised capital and accepts seed, early_stage_venture, late_stage_venture, private_equity, ipo or m_and_a. round_type selects the financing event type and can contain comma-separated values, such as series_a,series_b.

What is the difference between investor and lead_investor?

investor restricts results to rounds backed by a specified investor; lead_investor restricts them to rounds led by that investor. Each accepts a company or person permalink, UUID or Crunchbase URL.

Can I paginate funding rounds with every sort mode?

The documented default is sort=announced. announced and amount return one page, while rank supports deeper pagination. page defaults to 1 and accepts 1 through 100, but the accepted range is not a promise that all those pages are available.

Are the announcement date boundaries inclusive?

Yes. announced_after means announced on or after the supplied date, and announced_before means announced on or before it. Supply YYYY-MM-DD strings. These filters do not establish that every returned financial or date field will be populated.

How do I request equity rounds without debt or grants?

Set equity_only to the string true. The documented accepted values are true and false; the parameter remains a string rather than a Boolean input.

Are round amounts and valuations guaranteed to be present?

No. The unverified source example includes null amount, target_amount, company_funding_total, pre_money_valuation and post_money_valuation values, as well as null dates. No direct probe is recorded for this endpoint. Keep missing values unknown rather than treating them as zero or assuming the filters can recover undisclosed figures.
