Deal Flow

What is a deal flow?

Deal flow is the stream of investment opportunities a firm sees, measured as a pipeline rather than a list. Practitioners use it both for volume, how many opportunities arrive, and for quality, whether the good companies in a category reach the firm early enough to act. The usual phrasing is deal flow, not a deal flow.

Why it decides returns

Venture outcomes are concentrated, and the firms capturing them are not a fixed roster. Cambridge Associates, studying US venture returns, found that an average of 61 firms account for value creation in the top 100 investments in venture capital per year, and that after 1999, investments ranked 11 through 100 accounted for an average of 60 percent of the total gains generated by the top 100 investments per investment year, more than the top 10 produced. It also reported that for the last 10 years of its study period, 40 to 70 percent of total gains were claimed by new and emerging managers.

Read those findings together and the practical conclusion is specific. Access is not a permanent asset held by a handful of brands, and no firm sees everything. What a fund needs is reliable early sight of a defined slice of the market, plus a decision process that does not waste the sight it has.

The denominator is large. NVCA's 2026 Yearbook counts 2025 US activity as 5,049 pre-seed and seed deals worth $22.3 billion, 5,166 early venture deals worth $70.1 billion, 4,167 later venture deals worth $126.9 billion, and 937 venture growth deals worth $100.6 billion. That is more than 15,000 financings that closed, before counting the companies that raised nothing. A seed fund making five investments a year is choosing from a market of roughly ten thousand funded early-stage rounds, and its whole job is to make that selection non-random.

Where deal flow comes from

• Portfolio founders, who refer people they respect and who have first-hand evidence about whether the firm is useful.
• Co-investors and leads, who share rounds they cannot fill or cannot lead.
• Operators and domain experts inside a thesis area, including researchers, buyers and former employees of incumbents.
• Angels and scouts, who are usually earlier than institutional capital.
• Outbound sourcing against a market map, which is the only source a new firm fully controls.
• Accelerators and demo days, high in volume and low in exclusivity.
• Inbound from the website and cold email, which is where most firms spend the least attention and where the occasional outlier hides.

The distinction that matters is not inbound versus outbound. It is whether the firm sees a company before the round is competitive. Sight three weeks before a process starts is worth more than the same company arriving with a deck and a Friday deadline.

Worked example

The figures below are hypothetical and chosen so the arithmetic can be checked.

A seed fund tracks its funnel for a year: 1,800 opportunities logged, 400 first meetings, 90 second meetings, 30 companies into diligence, 12 term sheets issued, 8 closed.

Step one, the conversion rates. First meetings are 400 divided by 1,800, which is 22 percent. Diligence is 30 divided by 1,800, which is 1.7 percent. Closed deals are 8 divided by 1,800, which is 0.44 percent.

Step two, the term sheet win rate. Eight closed out of 12 issued is 67 percent, meaning a third of the fund's offers lose. That number, not the top of the funnel, tells the partnership whether it is competitive at its chosen price and stage.

Step three, sizing the pipeline against the portfolio plan. A fund that must make five new investments a year at a 0.44 percent conversion rate needs 5 divided by 0.0044 opportunities, which is about 1,136 a year, or roughly 22 a week. If the actual flow is 8 a week, the portfolio plan is not fundable from the current pipeline and either the sourcing has to change or the check size and position count do.

Step four, the capacity check. Four hundred first meetings across two investing partners is 200 each, or about four a week each, before diligence, board work and fundraising. Pipeline growth without a filter is a staffing problem, not an advantage.

How firms actually manage it

The instrument is a deal-flow CRM, and the fields that earn their keep are few: source, date first seen, stage at first contact, owner, decision, decision date, and reason. With those, a firm can answer the questions that change behavior. Which sources produced the companies that raised a strong next round? Where in the funnel do the best companies leave? How long after first contact does a decision get made, and does that number differ for the deals that were won and lost?

At the bottom of the funnel sits the written record. Bessemer Venture Partners publishes its historical memos as the early analysis behind its investment decisions, describing them as the due diligence documented before anyone knew how the story would end. That is the artifact that makes a pipeline reviewable years later: not the count of companies seen, but a record of what the firm believed at the moment of decision.

Passes deserve the same discipline. A logged pass with a stated reason and a revisit trigger converts a rejection into a sourcing asset, because the reason is testable later.

How a new firm builds flow from zero

A first-time manager has no portfolio founders to refer anyone and no exits to point at, so the only sources available are the ones that can be manufactured.

• Pick a narrow area and publish in it. Written work on a specific category reaches the founders in that category and costs nothing but time.
• Build the map before the fund closes. A list of every company working against a stated thesis is a sourcing asset that exists independently of reputation.
• Trade with people at the same stage. Other emerging managers share rounds because they need co-investors as much as the new firm does, and Cambridge Associates' finding that new and emerging managers claimed 40 to 70 percent of total gains over the ten years it studied is the argument for taking those introductions seriously.
• Go to the buyers, not the conferences. The procurement teams and practitioners inside the target customer set know which vendors are winning before any funding is announced.
• Answer everything for the first two years. Response discipline is the only reputation asset a Fund I manager can build immediately, and founders remember who replied.

Common mistakes

• Counting volume as quality. Ten thousand decks reviewed is a cost, not a moat.
• Measuring only the top of the funnel. Win rate on issued term sheets and loss reasons are the diagnostic numbers.
• Tracking sources without tracking outcomes. Attribution is only useful if it is joined to what happened next.
• Letting speed substitute for sight. Deciding in 48 hours on a competitive round is a symptom of arriving late, not of being decisive.
• Building the pipeline entirely on referrals from other investors, which guarantees the firm sees deals at the same time as everyone else and prices accordingly.
• Never revisiting passes. In a market where value creation spreads across dozens of firms a year, the companies a fund declined are a better hunting ground than its inbox.

Deal sourcing is the active work that produces flow, and a deal-flow CRM is the system of record for it. A pipeline is the same funnel viewed as stages, while deal velocity describes how fast opportunities move through it. An investment memo is what the surviving opportunities become, and pattern recognition is the judgment layer that makes a large funnel navigable without turning it into noise.
