Specter vs CB Insights

Over 400 VC funds run their sourcing on Specter: 55M+ companies, 550M+ people, 330K+ investors and 1M+ transactions, with new signals arriving daily.

A score tells you what a company is. A signal tells you what just happened. Specter is built around the signal: the moment revenue moves, a founder goes stealth or a tier-1 investor starts circling, you know, and you can be first to the conversation.

These are the main reasons investment teams choose Specter over CB Insights as their private market data platform:

Data coverage

CB Insights

Private-company coverage passing 11 million, per its January 2026 product launch, with particular depth on venture-backed and emerging tech.

Specter

55M+ companies and 550M+ people, roughly 5× the company coverage, plus 330K+ investors and 1M+ transactions. Most of the extra 44 million sits outside any research index: bootstrapped, stealth and just-founded companies that no score has reached yet, which is where you find deals before other funds do.

Depth per record

CB Insights

Company profiles built for assessment: funding history, scores, business relationships and market context.

Specter

250+ data points per company, 60+ per person: firmographics and funding history, hiring velocity, web and app traffic, app-store downloads and reviews, social reach, G2 and Trustpilot scores, plus news distilled from 60,000+ sources.

People & Talent

Only on Specter
CB Insights

Tracks companies, business relationships and alumni-founded startups; people data is not a standalone product.

Specter

550M+ people with 60+ data points each: verified role history, education, prior-employer pedigree, VC-backed and serial-founder flags, and verified email retrieval. On top of the graph, 1,000+ talent signals a day: stealth founders, unicorn and Fortune-500 spinouts, and fresh YC founders, flagged the day they surface.

Revenue Signals

Only on Specter
CB Insights

Shows estimated revenue on company profiles, alongside funding data.

Specter

Reported revenue whenever a company has disclosed it, plus 500+ verified revenue and profitability data points a day, checked by AI and humans, sourced from news, social, podcasts, press releases and filings. Every private company also gets a modeled monthly revenue estimate, anchored to verified disclosures with a P10/P90 confidence band.

Live valuations

Only on Specter
CB Insights

Shows estimated private valuations on company profiles, updated as rounds are disclosed.

Specter

Reported valuations whenever they're public, and a valuation that keeps moving between rounds: modeled monthly from revenue, funding history, investor quality and stage, re-anchored to every priced round, always with a confidence band that shows how reliable the number is.

Predictions

CB Insights

Mosaic scores 230,000+ companies from 0 to 1,000 across four factors, which CB Insights describes as covering more than 75% of venture-funded startups, with published methodology and validation. Commercial Maturity and Exit Probability scores sit alongside it.

Specter

Investor Interest Signals predict a specific near-term event: who is about to back or acquire whom, drawn from observed engagement between partners and founders. 7,000+ a week, each confidence-scored. A different kind of prediction: not how strong a company looks, but whether a deal is forming right now.

Freshness

CB Insights

Daily intel briefings, analyst reports across 1,500+ markets, and periodic score and dataset refreshes.

Specter

Specter updates continuously: 500+ revenue signals and 1,000+ talent signals land every day, with 7,000+ investor-interest signals arriving weekly, plus news from 60,000+ verified sources, all structured and company-linked. An event shows up in your feed the day it's detected.

AI Search & Agents

CB Insights

ChatCBI answers natural-language questions over its Business Graph, AI Agents handle scouting and diligence research, a Browser Analyst extension works alongside the browser, and an MCP integration shipped in January 2026.

Specter

Agents, Specter's agentic AI chat, are native to the product: quick to pick up, tunable with skills, and wired to the full Specter database plus web search. Natural-language and semantic search spans all 55M+ companies beside them. And Specter MCP plugs the dataset into Claude, Cursor, OpenAI, or any agent you already run, carrying 250+ data points per company, all four live signal feeds, and modeled revenue and valuation.

Delivery surface

CB Insights

Web platform and a broad enterprise surface: Salesforce, Snowflake, an Excel add-in, a Microsoft 365 Copilot connector, Affinity, Zapier and a mobile app, with an API on higher tiers (per third-party reporting).

Specter

Web app, the most complete and best priced API on the market, warehouse drops to AWS, GCP and Snowflake, a Chrome extension, CRM sync for Salesforce, Affinity, Attio and Airtable, and Specter MCP. The same dataset in every tool your team already uses.

What the API exposes

CB Insights

An API is available on higher-tier plans (per third-party reporting), alongside Snowflake delivery and the Excel add-in. Page sizes, rate limits and endpoint details aren't published.

Specter

Every signal feed is a first-class API resource: Revenue, Talent, Investor-Interest and News endpoints sit next to companies, people, investors and transactions. Anything your analysts watch in the app, your pipelines can query.

Specter has data CB Insights doesn't.

What CB Insights doesn't cover:

  • 44M more companies
  • A 550M+ person graph with verified emails
  • Stealth-founder detection, ~136K tracked
  • Live revenue signals, 500+ a day
  • Predictive investor-interest signals
  • A live valuation between rounds
  • Saved searches as live API feeds
  • And more

The most complete and best priced API on the market.

One REST API, built on OpenAPI 3.0, covers the whole platform: company, people, investor and transaction data, the four live signal feeds, and your team's network graph. A saved search in the app becomes a feed on the API, and plain-English queries run through a single AI-search endpoint across every product.

The best-priced API on the market

One Specter API reaches the entire platform: companies, people, investors, transactions, all four signal feeds and enrichment, the job most teams put it to first, with no web-app seat required. CB Insights gates API access to higher tiers, per third-party reporting.

Live signals, first-class endpoints

Revenue, Talent, Investor-Interest and News signals each get dedicated endpoints, carrying confidence scores, source attribution and dates. A score field tells you where a company stands today; a signal endpoint streams what changed this morning.

Estimates ship in the payload

The estimates endpoint returns modeled revenue and valuation with the median, the P10/P90 band, a confidence tier and the anchoring disclosures. The model's uncertainty travels with the number rather than hiding in a methodology page.

Ask in plain English

A single AI-search endpoint covers eight products: companies, people, investors, talent signals, interest signals, funding rounds, acquisitions and IPOs. Describe the target in a sentence and Specter converts it into filters and returns full record objects.

Searches double as live feeds

Any search or list saved in the app is readable over the API, with subscriptions for new matches as they land. Analysts and pipelines watch one surface. Creating and managing searches costs no credits; you pay only when data moves.

The team network, over the wire

Network endpoints return everyone your team collectively knows on LinkedIn, deduplicated across teammates: who holds a warm path into a target company, in what role, and which teammate should send the note.

Unmatched lookups cost nothing

Enrichment resolves companies, people and investors from a domain, LinkedIn URL or email, and credits are spent only on matches. A record Specter hasn't gathered yet gets queued on demand, so the retry can hit.

Throughput for warehouse-scale pulls

Pagination runs to 5,000 records per page at 15 requests a second, with bulk by-id endpoints on top. Rate and credit limits surface in X-RateLimit and X-CreditLimit headers, so pipelines back off cleanly instead of guessing.

Specter API vs CB Insights API
