Specter vs Harmonic

Yes, and more. Harmonic is a strong startup-discovery engine, and Specter is an excellent place to discover the next breakout too, thanks to the most exhaustive coverage in private markets and the richest industry taxonomy anywhere. Where Specter pulls ahead is everything that happens after the find: modeled revenue and valuation for every company, predictive investor-interest signals, and delivery on any AI agent. One platform carries you from sourcing through pricing to prediction, across the whole investment lifecycle.

Specter covers more of the market: 50M+ companies and 700M+ people, including the small bootstrapped companies that never show up anywhere else. It also has data nobody else sells. Every company gets a revenue estimate and a live valuation, and interest signals show which investors are circling a deal before it happens. The data stays fresh and clean, too. Signals arrive daily, revenue figures come from verified sources, and predictions carry confidence scores. And teams keep working the way they already do, in the browser, over the API, in a warehouse or CRM, or through the Chrome extension and Specter MCP.

Two-thirds more companies (50M+ vs Harmonic's published 30M+) and more than 3.5× the people (700M+ vs 190M+), alongside 350K+ investors, 1M+ transactions and 250+ data points per company. But raw size is only half of it: the coverage reaches deep into the long tail of bootstrapped and emerging companies that never make a list, and the richest industry taxonomy in private markets means you can actually surface them, sector by sector and niche by niche, instead of just storing them.

Fresher than anything else in private markets. The data is real-time: daily incrementals run across every dataset, company, people, investor, news, revenue, talent, transactions and funding signals. The API serves the live record, so what you pull is what's true right now. Some competitors serve snapshots that can run two weeks behind.

Specter cleans data before you ever see it. News comes from 60,000+ verified sources, and every story is scored for significance so noise stays out of your feed. Revenue figures are normalized to USD, with context and profitability flags attached. Predictive signals carry confidence scores. Every company, person, investor and transaction has a stable ID that links cleanly across the platform. That's a bar competitors don't hold, and it's why funds run their models on Specter data.

Yes, for every company, with confidence bands attached. It's a category Harmonic doesn't offer at all. Revenue is modeled monthly and anchored to every verified disclosure, and a live Revenue Signals feed adds 500+ verified data points a day from news, social, podcasts and filings. Valuation stacks on top, re-anchored to each priced round and re-rated monthly in between, so you always have a defensible, current number rather than a figure frozen at the last raise.

Yes. Agents, Specter's agentic AI chat, live natively in the platform. They're easy to use, adjustable through skills, and they pull from the entire Specter database plus web search to build context around whatever you're working on. Most clients pair Agents with the natural-language AI search across all 50M+ companies and the in-app AI competitor tooling. And through Specter MCP, Specter's tooling also runs inside Claude, Cursor, OpenAI, or any agent you already use.

Almost certainly. Specter ships as a web app, a best-priced REST API, bulk warehouse delivery (AWS, Google Cloud and Snowflake, in CSV or Parquet), a Chrome extension, CRM sync (Salesforce, Affinity, Attio and Airtable) and Specter MCP. It's the same data delivered where your team already works, with no migration project required.

Yes. Network tracking maps who across your team already knows a given founder or operator, so the warmest path to an intro surfaces right next to the data. No more guessing who can make the connection. The Chrome extension makes it a daily driver: open any company's site or LinkedIn page and your team's warmest paths appear right there. It's the same relationship mapping you'd expect from Harmonic, layered on top of Specter's exclusive revenue, valuation and predictive signals.
