What is the Harmonic API?

Harmonic provides an AI-first startup intelligence and private market database platform. Its developer-friendly API allows teams to programmatically discover early-stage firms, run automated background research, and enrich internal customer relationship management databases with real-time market signals.

Pricing-wise, Harmonic operates on custom enterprise agreements with pricing available only upon request via demos (reported at $10,000-$30,000 a year). Users choose plans based on deployment depth, ranging from programmatic data enrichment via API, no-code syncing options, to full data warehouse bulk integration.

Harmonic's primary client base consists of prominent VC firms, growth equity funds, and M&A teams who rely on the platform for proactive deal sourcing. Common use cases: automated inbound dealflow filtering, mapping founder/people movement, syncing private company insights into internal software/workflows.

Overview of Harmonic API alternatives

ProductOverviewPricingStrengthsLimitations
Multiples

Investment-grade financial data API provider. Complete coverage across both private and public comps. Public markets licensed from FactSet and Morningstar. Deal dataset includes data points across 500K+ transactions (M&A and funding rounds, minority and majority deals). Deeper actual data insights vs. Harmonic, valuation multiples and information on deal terms. Multiples can be the API complement to Harmonic, rather than the full substitute (use Harmonic for signals, Multiples for high-quality valuation data). Pricing starts at $1,499 a month.

  • Pro: $239/mo (billed annually) or $299 (monthly)
  • Pro Max: $399/mo (billed annually) or $499 (monthly)
  • API: from $1,499/mo
  • Free 3-day trial
  • Enterprise-grade API for both public comps and precedent transactions
  • Highest quality data (licensed from FactSet and Morningstar)
  • Affordable pricing vs. enterprise providers
  • No FX, fixed income or news
  • No real-time prices
Crunchbase

Crunchbase API provides programmatic access to startup profiles, funding rounds, amounts raised and investor data over a REST v4 interface. It records events after they are announced, whereas Harmonic tries to flag companies before a round is public through hiring and founder signals. Crunchbase carries almost no valuations or deal terms, the free tier was withdrawn, and API access is sold on enterprise plans (reported from $30,000 a year).

  • Pro: $49/user/mo (billed annually) or $99 (monthly)
  • Business: $199/user/mo, billed annually
  • API: custom quote, reported $30K+/yr
  • Widest net on companies and funding rounds
  • Simple, documented REST API
  • No valuation multiples or deal terms
  • Very limited M&A data
  • No financials or estimates
  • No public comps data
PitchBook

PitchBook API delivers the deepest private markets dataset - deals, deal terms, funds, fund returns, LP commitments and people. Compared to Harmonic, PitchBook is built around confirmed transactions and fund data rather than early sourcing signals. It is also far more expensive: a platform license plus a standalone API agreement, reported from $70,000 a year.

  • Custom quote
  • Reported $25k-$40k+/yr for a base license
  • $70k+ for API
  • Great across private data
  • Decent insights of fund returns and LP commitments
  • Programmatic email/contact data
  • Various delivery sources (API, bulk delivery, feed)
  • Platform license needed to access the API
  • Very expensive - reported from $70,000 a year
  • Public company data is thinner than FactSet, Multiples or Capital IQ
Grata

Grata API exposes a proprietary US-centric dataset of 21M+ private companies and 8M+ executive contacts through Search, Similar and Enrichment endpoints. It focuses on the US mid-market, including bootstrapped and founder-owned companies that never raised VC money (which Harmonic-style signal tracking tends to miss). Neither Grata nor Harmonic provides much financial data, deal terms or public comps.

  • Custom quote
  • Reported $15k-$40k/yr depending on number of seats
  • API pricing quoted separately
  • Great for programmatic access of bootstrapped companies data
  • Executive contacts directory
  • Very US-centric
  • No financials or company valuations
CB Insights

CB Insights API returns company profiles, funding data, market maps and its proprietary Mosaic scores. It is a research product first, sold to platform customers rather than as a standalone feed, and reported at $40,000-$100,000 a year. Harmonic is the more API-native option and stronger on early signals, whereas CB Insights is better for packaged sector research and curated trend data.

  • Custom quote
  • Reported $40k-$100k/yr
  • Proprietary data on emerging tech markets
  • Various delivery sources (API, bulk delivery, feed)
  • Analyst research accessible alongside the data
  • Enterprise pricing on top of a premium platform
  • Limited valuation data or deal terms
  • No enterprise-grade public comps data

Should you choose Harmonic or look for an alternative?

Harmonic strengths

  • API-native product, wide company and people graph aimed at early stage and stealth discovery
  • Signals from hiring, web, and talent activity that e.g. Crunchbase often misses
  • Deep integration / delivery - S3, BigQuery or Snowflake on a weekly refresh, native Salesforce, HubSpot and Affinity integrations

Harmonic trade-offs

  • Harmonic is a company intelligence product, does not have investment-grade financials, public comps data, etc.
  • Contact data is thin; teams usually pair it with a separate enrichment vendor
  • Coverage is broad, but not audited PE/VC deal terms like Multiples or PitchBook

Why Harmonic API might not be the best choice for your team

No deal terms or valuations

Harmonic tracks company and people activity. It does not carry round valuations, deal terms or exit multiples, so it is not the best source if you require IB-style transaction feed or valuation multiples.

Sourcing tool, not a research database

Harmonic is built to find early-stage and stealth companies from hiring and web signals. It is not PitchBook - you do not get cap tables, deal terms, fund performance or anything similar. Choose other providers if you look more for a database product.

No public markets data

Harmonic API does not include any data on public comps. For that, consider Multiples, FactSet, Capital IQ or LSEG.

Limited use case outside of tech

Harmonic API performs strongest when you are a VC looking for early-stage opportunities. It is weaker for traditional PE, strategic M&A, and generally non-tech segments.
