VC deal sourcing is how investors find the startups they end up funding, and most of it runs through people. In [a survey of 885 VCs](https://www.nber.org/system/files/working_papers/w22587/w22587.pdf), over 30% of deals came through professional networks and 20% through other investors. Only 10% arrived inbound from founders. Below are the channels behind those deals, how data tools change the mix, and how to measure each channel. ## Where VC Deals Come From The survey, by Paul Gompers, Will Gornall, Steven Kaplan and Ilya Strebulaev, asked 885 institutional VCs at 681 firms how they work. Over 30% of their deals came through professional networks. Another 20% were referred by other investors, and 8% by portfolio companies. Almost 30% were proactively self-generated, meaning the investor went looking. Only 10% came inbound from company management. So close to six in ten deals started with an introduction, and the cold pitch was the smallest source. The survey dates from 2016, before most data tools for sourcing existed. Our reading is that the proactive share has grown since. We found no newer survey of the same size to confirm it. ## The Main VC Deal Sourcing Channels Each channel below feeds one of those sources. Firms weight them by stage, sector and how much time partners can give. - **Professional networks.** Former colleagues, operators and advisers who know your thesis pass on founders they rate. - **Co-investors.** Other VCs and angels share rounds too large or too early for them alone. - **Portfolio founders.** Founders you backed know other founders, and their referral carries a view on the person. - **Accelerators and demo days.** Y Combinator, Techstars and 500 Global run batches that end with founders pitching investors. - **Angel networks and syndicates.** Angels often see a company a round earlier and flag it when the next round needs a lead. - **Events.** TechCrunch Disrupt, Web Summit and sector conferences put founders and investors in the same room. - **Data platforms.** PitchBook, Crunchbase and CB Insights track rounds, while Product Hunt, GitHub and hiring pages show early activity. - **Inbound.** A clear thesis page and useful writing bring founders to you, mostly already filtered by fit. The first three are relationship channels, and they account for most closed deals in the survey. The rest widen the top of the funnel. Proactive sourcing usually ends in a direct message or [a cold email a founder will answer](https://qubit.capital/blog/investor-outreach-email-template). The note works when it names the company’s recent progress and why it fits your thesis. ## Data-Led Sourcing: Hiring, Code and Product Signals Data tools find companies before anyone introduces them. They read signals such as hiring, team size, web traffic, app downloads and developer activity. Vertex Ventures South-east Asia and India built one of these systems. Its aim was to look past its network’s leads, partner Genping Liu wrote in [The Business Times](https://www.businesstimes.com.sg/wealth/wealth-investing/what-does-ai-mean-us-venture-capital-deal-sourcing-case-study). The system scans thousands of companies from LinkedIn and other sources and hands the team a list to review each week. Liu says it has not yet found the next unicorn, and that it was never meant to replace human analysts. The working rule: let data build the long list, and let a person judge the founder. ## How Do VCs Find Startups That Come to Them? Inbound is the smallest source in the survey, and its quality depends on how plainly a firm says what it funds. Carter Williams described the effect of a thesis page in [a LinkedIn discussion](https://www.linkedin.com/advice/3/what-strategies-can-you-use-stand-out-crowded-deal-bx4uc) on deal sourcing: > “We have created a webpage that explains what we invest in, what we do not invest in, and areas to change our mind.” The result, in his words, is that “we see fewer irrelevant deals and more good deals.” A page like that also cuts the time partners spend saying no to companies outside the thesis. Recurring formats give founders a reason to come to you. [Virtual office hours](https://qubit.capital/blog/investor-virtual-office-hours) let one partner meet several early founders in an afternoon. Partners who post useful analysis draw founders who already know the thesis. The same platform works in reverse, and [investors search LinkedIn for startups](https://qubit.capital/blog/investors-find-startups-linkedin) by role, company and recent posts. ![The image outlines which social platforms (LinkedIn, X, niche forums) are most effective for different startup types.](https://qubit.capital/wp-content/uploads/2025/08/Social-Platform-for-startup-discovery_11zon.webp) ## Tracking Deal Flow Sourcing by Channel For each deal a firm closes, it considers roughly 100 potential opportunities, the same survey found. More sourcing only helps when you know which channel sends the companies you fund. Danielle Morrill, then CEO of Mattermark, which sold data tools to investors, made the point in [TechCrunch in 2015](https://techcrunch.com/2015/03/08/what-ive-learned-about-deal-sourcing/): > “Few investors view the deal pipeline like a sales process, measuring conversion from one step to the next and iterating constantly to make it better.” Log the source of every company in your CRM, from first meeting to term sheet. After two quarters, compare each channel’s share of meetings with its share of investments. Fund or cut channels on that ratio, not on volume. Software can do the counting for you. Tools for [deal sourcing and pipeline management](https://qubit.capital/blog/deal-sourcing-pipeline-management) tag each company with its source as it enters the pipeline. ## Building Your Pipeline Start with the channels that close deals: networks, co-investors and portfolio founders. Then add data tools and a public thesis page to widen what reaches them, and track every source.
