Specter vs Dealroom
Over 400 VC funds run their sourcing on Specter: 50M+ companies, 700M+ people and 1M+ transactions, with thousands of fresh signals arriving every day.
Dealroom is the source of record for European ecosystem data, and it earned that standing. Specter does a different job: it watches what happens inside companies in real time, so you know the moment a founder goes stealth, revenue moves, or a tier-1 partner starts circling. A map shows you the market. A signal shows you the moment.

Here are the main reasons VCs pick Specter over Dealroom when the job is finding deals, not mapping markets:
Data coverage
A curated, precisely tagged global tech database with the best European depth on the market. Third-party write-ups report coverage of roughly 4M+ companies (Ellty, 2026); Dealroom itself doesn't headline a count.
50M+ companies and 700M+ people, from garage-stage and stealth through decacorn and public, plus 350K+ investors and 1M+ transactions. Most early deals come out of that long tail, and whole-market coverage decides what you can find at all.
Depth per record
Profiles carry funding history, headcount growth, valuation and revenue estimates with EV/ARR multiples, cap-table and ownership breakdowns, and research notes.
250+ data points on every company and 60+ on every person: firmographics and funding, hiring, web and app traffic, app reviews, social reach, G2 and Trustpilot scores, and news distilled from 60,000+ verified sources.
People & founders
Key people and talent scores on company profiles, plus alumni and spinout research. Reviewers describe it as a market-mapping tool rather than a contact database (Tomba, 2026).
A 700M+ person graph with 60+ data points each: verified role history, education, prior-employer pedigree, VC-backed and serial-founder flags. Verified emails come back per person or in bulk, so you can start outreach the same day you find someone.
Stealth & pre-company
Only on SpecterA "Just founded" feed surfaces pre-funding companies once a founder and an entity become visible.
Specter goes a step earlier: ~136K stealth founders tracked, plus new YC founders and applicants, and spinouts from unicorns and the Fortune 500. You hear about it the moment someone leaves, not the moment they incorporate.
Predictive intent
Only on SpecterSignal scores and a real-time newsfeed report what has become visible: funding events, growth, news.
Investor Interest Signals read observed engagement between partners, founders and C-suites: 7,000+ a week, confidence-scored, flagging who is likely to lead a round or make an approach before the headline exists.
Revenue & valuation
Valuation and revenue estimates with EV/ARR multiples on company profiles, alongside cap-table and ownership data.
Reported revenue and valuations whenever they're public, and modeled monthly revenue and valuation for every private company, each with a P10/P90 confidence band and the verified disclosures it's anchored to, re-rated every month instead of freezing between rounds. Both platforms model estimates; Specter publishes how each number was built.
Signal volume
A live newsfeed, company signal scores and continuously updated data, with flagged errors fixed quickly.
500+ revenue signals and 1,000+ talent signals every day, plus 7,000+ investor-interest signals a week, with news distilled from 60,000+ verified sources. Enough new signal that teams review it daily rather than weekly.
AI Search & Agents
An agentic REST API and a hosted MCP server bring Dealroom's data into AI tools and agents.
Agents, Specter's agentic AI chat, are built into the platform: simple to use, tunable through skills, and grounded in the full Specter database plus web search. Natural-language and semantic search covers all 50M+ companies. And Specter MCP puts the dataset inside Claude, Cursor, OpenAI, or any agent, with all four signal feeds included.
Delivery surface
Web platform, connectors for HubSpot, Salesforce, Slack, Zapier, n8n and Affinity, data rooms bundled into higher tiers, and custom datasets on request.
Web app, the best-priced API on the market, bulk delivery to AWS, GCP and Snowflake in CSV or Parquet, a Chrome extension, CRM sync for Salesforce, HubSpot, Attio and Airtable, and Specter MCP. The same dataset in each of those tools.
What the API exposes
An agentic REST API over Dealroom's data. Endpoint counts, page sizes and rate limits aren't published (per Dealroom's public materials, August 2026).
Around 64 endpoint paths behind one key: companies, people, investors with funds and portfolios, transactions, estimates, network and verified emails. Signal feeds are first-class endpoints, and pages return up to 5,000 records.
Specter has data Dealroom doesn't.
A short list of what lives on Specter and not on Dealroom. The full inventory is on the platform page.
Things Dealroom doesn't carry:
- A 700M+ person graph, 60+ points per profile
- Verified emails, per person and in bulk
- Predictive investor-interest signals
- 500+ live revenue signals a day
- ~136K stealth founders tracked
- New YC founders and applicants
- Confidence bands and anchors on every estimate
- And more
The API private-markets teams build on.
One REST API, built on OpenAPI 3.0, covers everything Specter tracks: company, people, investor and transaction databases in full, all four signal feeds, modeled estimates and the team network graph. Lists and saved searches from the app double as live feeds, and a plain-English AI-search endpoint spans every product. It's the most complete and best priced API on the market.
The best-priced API in private markets
One Specter API carries the whole platform: full company, people, investor and transaction data, all four signal feeds, and enrichment, the job most teams put it to first. Enrichment work doesn't require a web-app seat, and it's the best priced API on the market for what it returns.
Signal feeds as endpoints
Revenue, Talent, Investor-Interest and News signals each have their own endpoints, carrying confidence scores, source attribution and dates. The proprietary feeds you watch in the app are addressable in code.
Estimates ship in the payload
The estimates endpoint returns the median alongside p10, p90, a confidence score and the anchor disclosures behind it. Uncertainty is a field in the response, so anything downstream can weight the number instead of guessing at it.
One key, every entity
Around 64 endpoint paths sit behind a single team key: companies, people, investors with funds and portfolios, funding rounds, acquisitions, IPOs, estimates, network, verified emails and logs.
Plain English in, records out
A single AI-search endpoint spans eight products: companies, people, investors, talent signals, interest signals, funding rounds, acquisitions and IPOs. Describe the target in a sentence and Specter builds the filters and answers with complete record objects.
Saved searches turn into pipelines
Any search or list an analyst builds in the app can be read over the API and subscribed to, so new matches flow straight into your tooling. Building searches and lists is free of charge; credits go only to the data you actually pull.
Unmatched lookups cost nothing
Enrichment resolves companies, people and investors from a domain, LinkedIn URL or email, and charges only on a match. A record Specter doesn't hold yet is gathered on demand, so the same call can succeed next time.
Built for warehouse-scale pulls
Pages carry up to 5,000 records at 15 requests per second, with bulk by-id endpoints for companies, people and talent. Full-dataset delivery lands in AWS, Google Cloud or Snowflake as CSV or Parquet, estimates file included, and docs ship as llms.txt, llms-full.txt and Markdown per page.
Specter API vs Dealroom API
Specter's figures come from its API documentation; Dealroom's side reflects its public site as of August 2026. "Not published" means Dealroom doesn't state a figure publicly, not that the capability is missing.

For deal sourcing, yes. Dealroom is the source of record for ecosystem data, especially in Europe, and it's excellent at market-level questions: how a region is performing, how a sector is funded, where a country ranks. Specter is built for company-level and founder-level questions: which startup just hit an inflection, which founder just left a unicorn, which investor is circling a deal. It tracks 50M+ companies and 700M+ people in real time, with signal feeds no mapping platform carries. Plenty of European funds run both; when the job is finding and winning deals, Specter is the layer that does it.
Three reasons come up most. Scale: Specter tracks 50M+ companies and 700M+ people, where third-party write-ups put Dealroom's curated coverage around 4M+ companies (Ellty, 2026). People: a full person graph with verified role history and retrievable emails, where Dealroom offers key people and talent scores on profiles. And timing: predictive investor-interest signals, ~136K tracked stealth founders and 500+ revenue signals a day tell you when to move, not just where to look.
Specter tracks 50M+ companies, 700M+ people, 350K+ investors and 1M+ transactions, with 250+ data points per company and 60+ per person. Dealroom doesn't publish a company count; third-party reviews report roughly 4M+ curated companies (Ellty, 2026). The gap matters most in the long tail: bootstrapped, stealth and just-started companies that a curated tech database hasn't tagged yet are exactly where sourcing edges live.
It does, and they're good: signal scores, a real-time newsfeed and a "Just founded" feed for pre-funding companies. The difference is what the signals see. Dealroom's report what has become visible. Specter's Investor Interest Signals are predictive, reading observed engagement between partners and founders to flag who is likely to lead a round before anything is announced. Its talent feed catches founders at the moment they go stealth, at roughly 30K talent signals a week. Observed tells you what happened; Specter also tells you what's about to.
Both model estimates, and Dealroom pairs theirs with EV/ARR multiples and cap-table data. Specter's difference is transparency and cadence: every estimate ships with a P10/P90 confidence band and the verified disclosures it's anchored to, and it re-rates monthly rather than holding still between rounds. You can see how much to trust the number before you use it, and the band widens honestly when signal is thin.
Specter covers Europe as part of a 50M+ company global index, and European funds are among its heaviest users. That said, Dealroom's European depth is the best in the market, and its ecosystem partnerships with governments and agencies are a franchise Specter doesn't compete for. If the job is publishing a national report, Dealroom is the right tool. If the job is finding the next European breakout before the round happens, funds pair Specter with it, or run Specter alone, for the people graph, the stealth detection and the predictive signals.
The data is real-time. Daily incrementals run across every dataset: company, people, investor, news, revenue, talent, transactions and funding signals. The API always serves the live record, so a pull reflects what's true at that moment rather than a snapshot.
Yes. Agents, Specter's agentic AI chat, run natively in the platform: straightforward to use, extendable with skills, and grounded in the entire Specter database plus web search. Natural-language and semantic search covers all 50M+ companies alongside them. And Specter MCP takes the dataset into Claude, Cursor, OpenAI, or any agent you already work in. Dealroom also offers a hosted MCP server, so on agent access the two are peers; the difference is the data on the other side of the connection.
The API is a paid product, and access is approval-based rather than self-serve: talk to the team and you'll be set up with a key. What you get is the most complete and best priced API on the market: companies, people, investors, transactions, estimates, verified emails, the network graph and all four signal feeds behind one key, with pages up to 5,000 records and docs published in LLM-native formats.
Very likely. It ships as a web app, an API, bulk warehouse delivery to AWS, Google Cloud and Snowflake in CSV or Parquet, a Chrome extension, CRM sync for Salesforce, HubSpot, Attio and Airtable, and Specter MCP for agents. One dataset arriving wherever your team already spends the day, with nothing to migrate.
