Proprietary deal flow is earned through a deep understanding of markets and exposure to talent. Funds that generate DPI at scale know which founding teams have the technical depth to win their category and which markets are at an inflection point before the round is priced. 

Harmonic gives investment teams the data and research infrastructure to form their understanding of markets and talent flows: proprietary coverage of more than 35 million venture-backable companies and over 195 million people across the full organizational chart, with Scout, an AI research agent that turns that data into structured analysis on demand.

The sourcing problem in venture capital

Venture capital firms must understand which founding teams have the right skills and background for their journey, and which markets are worth backing before others. The databases and sourcing tools VCs historically relied on were built for tracking deals, not for forming conviction. These platforms index companies after a round closes and refresh on a quarterly cycle. By the time a company appears, the round has closed, and the valuation has changed. Plus, people data stops at the executive layer. So, teams end up working with a funding history and an executive contact list, which is enough to confirm a company exists, but it’s too thin to evaluate it.

These limitations apply at every stage. Whether evaluating a seed-stage founding team or a growth company's ability to scale, the questions that drive conviction (e.g., Who is building the product? How has the team evolved? Does the market trajectory justify the price?) are rarely answered by a funding history and a contact list.

How Harmonic supports VC work

Harmonic is a startup intelligence platform that combines proprietary data on venture-backable companies with profiles spanning every level of the organizational chart, giving investment teams a more complete and granular view of the market than traditional databases can provide. Scout, Harmonic's AI research agent trained on proprietary private market data, handles everything from market mapping to IC preparation, all from the same data that powers sourcing and diligence.

Discover companies and founders across the full market

The signal that a company is worth backing often appears before any database has indexed it. A principal researcher leaves a foundation model lab. A repeat founder goes quiet after an acquisition. Two engineers with complementary backgrounds stop updating their LinkedIn. 

Harmonic’s data surfaces talent movement, company formation activity drawn from legal filings, accelerator feeds, and direct founder submissions. Harmonic also highlights hiring patterns that indicate a team is assembling around a new idea before any announcement has been made.

An Earlybird VC benchmark of 1,000 companies spanning stealth founders through growth stage found that legacy platforms tracked around 75% of the relevant signals. Harmonic tracked 98%. That 23-point gap is the difference between a complete view of a market and one built from companies that have already made themselves visible.

On Harmonic, priority companies refresh daily on a cohort-based cycle, so the intelligence on a company reflects what is happening now. Harmonic also takes in data directly from venture firms and all major accelerators, and receives constant portfolio updates from the world's leading investors, giving it earlier and more accurate coverage than databases that depend on public announcements.

Research markets and build theses with Scout

The process of forming a thesis is slow by design, involving sector deep dives and the generation of structured market maps. Given the heavy time investment, the information collected is often already partially stale by the partner meeting.

Harmonic's AI agent, Scout, compresses that thesis-forming work into a single query. Scout pulls from its proprietary data to surface the founders, companies, and market patterns that define a sector. Ask Scout to map the AI infrastructure landscape, and it returns a structured view of the players, their funding stages, and how the market is moving, which is the kind of output that previously took weeks of analyst time to produce.

Evaluate companies and build conviction before investing

Conviction is what gets a deal to IC. The work between a first signal and an investment memo typically involves several tools and takes up associate time. Mapping the competitive field and stress-testing the team's ability to execute requires information from separate sources. 

Harmonic’s Scout handles the research that teams need to evaluate companies and build conviction, enabling informed decision-making. Describe the investment criteria in natural language, and Scout will return a structured analysis grounded in Harmonic's proprietary data. Ask it to evaluate a company's likelihood of winning a specific vertical, and it reasons from what Harmonic knows about the founders and the competitive field, alongside the traction signals visible in the data.

When that evaluation points to a team worth pursuing, a VC firm would typically have to turn to a separate enrichment vendor to get a contact detail. Harmonic's wide-spanning people database provides email addresses for most contacts, so the outreach can begin without switching tools or exporting data.

‍

Centralize sourcing, research, and decision workflows

Investment teams often run their workflow across disconnected systems. A company surfaces in a sourcing tool, and notes get added in the CRM, while the warm intro path lives in a partner's email inbox. When the same company resurfaces six months later through a different channel, the whole team doesn’t have the full context.

Harmonic centralizes the full sourcing-to-decision workflow in one place. The proprietary data that powers discovery also powers Scout's evaluation layer and a firm's pipeline management. Scout searches across the firm's own network, including LinkedIn and calendar connections, to surface who already has a relationship with a target company before the team sends a cold email. Harmonic integrates natively with Affinity and provides API and MCP access for firms that want Harmonic's data to flow into their existing infrastructure. As a result, the firm doesn’t have to rebuild context every time a company resurfaces. Instead, it can work from a complete, continuous record.

This same infrastructure extends to portfolio support. VC firms can use Scout to find talent and vendors for portfolio companies, running natural-language searches across Harmonic's people data to surface candidates matching specific technical or functional criteria.
