Transactions

Funding rounds, acquisitions and IPOs each with a stable ID and both sides of the deal resolvable

Funding rounds, acquisitions, and IPOs across 1M+ global transactions. Specter’s transactions dataset captures deal activity across private and public markets. Each transaction has a stable ID (fnr_, acq_, ipo_) and links directly to the companies and investors involved.

Data categories

• Funding rounds — investment_type (Seed through Series J, plus Undisclosed), raised_amount_usd, announced_on, pre- and post-money valuations, and the full investors list with an is_lead_investor flag.
• Acquisitions — both sides of the deal (acquirer_company_id / acquiree_company_id with names and domains), acquisition_type (acquisition, merge, lbo, acquihire, management_buyout), price_usd, acquisition_date.
• IPOs — issuing company, exchange, ticker, pricing, and capital raised.
• Participants — investors and companies, resolvable to full profiles via their IDs.

How to use the API

Start with what you have

• A company → Get company funding rounds, Get company acquisitions, or Get company IPOs.
• An investor → Get investor funding rounds.
• A transaction ID → Get funding round by ID (fnr_), Get acquisition by ID (acq_), or Get IPO by ID (ipo_).

Expand from a transaction

• Funding round → each investor’s investor_id → Get investor by ID.
• Acquisition → acquirer_company_id or acquiree_company_id → Get company by ID.
• IPO → issuing company → Get company by ID.

Notes

• Transaction data is usually reached via a company or an investor, then drilled into by transaction ID.
• Deal terms (amount, valuation) are null when undisclosed — never 0.
• Funding rounds carry the full investor list with a lead flag (is_lead_investor); acquisitions carry both the acquirer and acquiree company IDs.
• Transaction IDs are prefixed (fnr_, acq_, ipo_); the company and investor IDs inside them chain to the Companies and Investors APIs.
