The median venture capital firm looks at about 100 companies for every one it invests in. In information technology the figure is 151 (Gompers, Gornall, Kaplan and Strebulaev, survey of 885 venture capitalists, NBER Working Paper 22587, 2016). The ratio illustrates how selective the process is. For an event organiser, the practical question is how many participating startups fit each investor’s criteria.
Investors call that stream of opportunities deal flow. It also provides a way to assess which opportunities came from a conference, demo day or pitch night. This guide explains what the term means, how the funnel behind it works, why 2026 makes filtering more valuable than volume, and what your event has to deliver to count as a deal flow channel.
Help investors judge the event by showing them relevant startup profiles and opportunities for prepared conversations. Overall attendance alone gives them little basis for that decision.
What is deal flow?
Deal flow is the stream of investment opportunities a venture capital (VC) firm or business angel receives and reviews over a period, from the first contact through screening to an investment decision. A fund with strong deal flow sees enough relevant companies, early enough, to choose the best of them. Less relevant deal flow limits that choice and increases the work needed to find suitable companies.
The term is used in private equity, mergers and acquisitions and commercial real estate as well. This guide stays with startups and venture investors, because that is where events play their biggest role.
Three neighbouring terms are often mixed up:
- Deal sourcing: the activity of finding opportunities, from outbound research to referrals and events. Sourcing fills the top of the deal flow.
- Pipeline: the companies currently moving through a fund’s evaluation stages. The pipeline is a snapshot; deal flow is the stream over time.
- Deal flow management: the tools and routines a fund uses to log, tag and track opportunities, often in a customer relationship management (CRM) system built for investors.
Both spellings are in use. “Deal flow” as two words is the more common form in English, while “dealflow” appears in brand names and in German.
Where deal flow comes from
Knowing the sources tells you which role an event can realistically play. In the same survey of 885 investors, only 10 per cent of deals came inbound from the startup’s own management team. Over 30 per cent came through professional networks, roughly 30 per cent were proactively generated by the investors themselves, 20 per cent were referred by other investors and 8 per cent came from portfolio companies (NBER Digest, December 2016). Why this makes investors treat a conference as a network accelerator rather than an inbox, and what that means for recruiting them, is the argument of our guide on why investors attend startup conferences.
An event can bring several of these sources together through introductions, co-investor conversations and direct contact with startup teams. Profiles shared in advance and time for relevant conversations help investors use that access.
The deal flow funnel: from 100 opportunities to one deal
Deal flow becomes useful once you see it as a funnel. The survey paper describes the stages as ratios: one in four opportunities leads to a meeting with management, a third of those are reviewed at a partner meeting, about half of those move on to due diligence, and roughly a third of the companies in due diligence receive a term sheet.
The venture capital deal funnel
What happens to 100 opportunities at the median VC firm
Events act on the first two bars. The first look and the first meeting with a founding team are exactly what a demo day, a pitch session or a scheduled 1:1 produces. The later stages happen in the fund’s office, weeks after your venue has been cleared.
Design selection and scheduling to help investors identify which companies they want to meet.
Picture the associate a fund sends to your conference. On Monday she has to tell the partner meeting what she brought back. If she saw 60 pitches and four fit the fund’s stage and sector, her report is short. If she had eight scheduled conversations and six fit, she brings back six names and a reason to return next year. The survey is ten years old. Use its ratios to illustrate the selection process rather than forecast results for your event.
Why filtering matters more in 2026
Recent market reports show capital becoming concentrated in fewer deals.
Venture market 2026
More money, fewer deals
According to KPMG, investors “continued to concentrate their capital on either AI companies, or mature companies with proven value” (Venture Pulse press release, July 2026). For Europe, the same release notes a preference for “a small number of high-quality transactions”.
For your event, the relevant question is still which companies fit each fund’s thesis. Collect those criteria before promoting the startup list, so investors can assess whether the programme is useful to them.
Which startup events produce deal flow
If filtering is the job, the formats on your agenda do it very differently. They differ in how much filtering happens before the investor arrives, and in what she can take home.
| Format | What the investor sees | Filtering before the event | Typical output for the investor |
|---|---|---|---|
| Demo day | A curated cohort pitching on stage | High: the accelerator selected the batch | A shortlist from one cohort, follow-up requests |
| Pitch competition | Finalists pitching to a jury | Medium: selected for the contest, not for her thesis | Visibility of a few companies, rarely a fit |
| Conference with 1:1 matchmaking | Scheduled meetings she accepted in advance | High, if profiles and rules are good | First meetings with founding teams, notes for the partner meeting |
| Office hours | Founders who booked her slots | Low to medium: founders choose her | Many short conversations, mixed relevance |
| Side events | Small dinners or breakfasts by theme | Varies with the host | Relationships and referrals from co-investors |
| Investor day | Other investors, sometimes limited partners | High: investors only | Co-investor contacts, referrals |
Two lessons follow from the table. Formats that filter against the investor’s own criteria produce first meetings; formats that filter for the audience produce visibility. Decide whether each format is intended to create visibility or prepare specific investment conversations.
Scale alone does not settle it. Slush 2026 advertises more than 25,000 meetings for over 12,000 attendees, with one VC for every two founders (slush.org, accessed October 2026). Slush leads with meetings, not with stage time. Research points the same way. In a 2025 working paper draft covering 30 accelerators and 4,817 investors, Sheryl Winston Smith and Christian Anker (BI Norwegian Business School) found that online demo days brought more investors into each financing round. They describe the result as a paradox of plenty: wider access, and more uncertainty about each company.
If a demo day is on your agenda, the way the cohort is selected decides its deal flow value, which is why our organiser’s guide to what a demo day is starts with selection. A jury looks for different things than a fund does, as our guide on how to run a pitch competition shows. And partner dinners work as referral channels only when they stay out of your meeting hours, the main rule in our guide to side events at startup conferences.
How to make your event a deal flow channel
Back to the 100 to 1 arithmetic. A fund partner who closes two deals a year needs roughly 200 first looks to get there (our own calculation from the survey median). A demo day with 40 startups covers a fifth of that on paper. If only six of them fit her stage and sector, the afternoon delivered six. This is an illustration of why fit matters, not a target conversion rate for an individual fund.
Five decisions do most of the work:
- Collect the thesis, not just the logo: ask every investor for stages, sectors, geographies, ticket size and the number of meetings they want. These fields are your filter.
- Publish startup profiles before the event: give investors a searchable list with round, traction and sector weeks ahead, so the first look happens before they travel.
- Schedule the first meeting: turn interest into confirmed 1:1 slots with double opt-in, so both sides arrive prepared and the meeting counts as the “meeting with management” in the funnel.
- Cap the requests: a limit on how many requests one investor receives protects the people you worked hardest to recruit. Our playbook on preventing investor overload sets out the mechanics.
- Track the next steps: count follow-up meetings and next steps per investor in the weeks after the event, as described in our guide to tracking investor follow-ups after a demo day.
Qualification works in both directions. Not every person with “investor” on the badge is actively deploying capital, which is why we recommend qualifying investors before a 1:1 meeting marathon.
Converve runs these decisions inside a rule-based meeting matrix. You define which groups can meet, which profile fields filter the suggestions and how many requests each investor receives, and every match can be explained by a visible rule. The format itself, from profile data to meeting logistics, is explained in what investor matchmaking is. See how it works for startup and investor events.
Frequently Asked Questions
What does deal flow mean in venture capital?
Deal flow is the stream of investment opportunities a venture capital firm or business angel receives and reviews over a period, from first contact through screening to an investment decision. The more relevant the opportunities and the earlier a fund sees them, the stronger its deal flow.
Is it deal flow or dealflow?
Both spellings mean the same thing. In English, “deal flow” as two words is the more common form; “dealflow” appears in company names and is the usual spelling in German.
How many deals does a VC look at before investing?
In a survey of 885 venture capitalists, the median firm considered about 100 opportunities for every deal it closed, 151 in information technology and 78 in healthcare (Gompers et al., NBER Working Paper 22587, 2016). Roughly one in four opportunities led to a meeting with management.
Where do VCs get their deal flow?
Mostly from relationships. Over 30 per cent of deals came through professional networks, about 30 per cent were generated proactively by the investors, 20 per cent were referred by other investors, 10 per cent arrived inbound from founders and 8 per cent came from portfolio companies (NBER Digest, 2016). Events strengthen the network and outbound channels when they are well curated.
Are demo days a good source of deal flow?
They can be, because an accelerator has already selected the cohort. Their weakness is that the selection was made for the programme, not for an individual investor’s thesis. Demo days produce the most deal flow when investors receive startup profiles in advance and can book follow-up meetings directly.
How do VC firms manage high-volume inbound deal flow?
Most funds log every opportunity in a dedicated system, tag it by stage and sector, and screen it against their thesis before anyone takes a meeting. Event organisers can help by collecting the same structured data at registration, so investors can review profiles against their own criteria before requesting meetings.
Deal flow is the investor’s measure of your event
Collect investor theses, publish startup profiles early and make room for prepared conversations. Afterwards, ask which contacts led to further meetings. That gives you a concrete basis for showing investors what the event contributed to their search.
