How do I prove a repeatable sourcing edge?

Network against edge, stated precisely

A network produces deals when you work it. An edge produces deals because of a structural position that exists whether or not you are working it that week. Allocators test which one you have by asking what happens to your deal flow in a quarter when you are distracted.

• A network is people you know. An edge is a reason people you do not yet know are sent to you.
• A network scales with your calendar. An edge scales with a community, a product, a programme, or a role you hold.
• A network is hard to describe to a stranger. An edge can be named in one sentence and checked by calling somebody in it.
• A network dies when a partner leaves. An edge that also dies when a partner leaves is a key-person risk an allocator will price, and saying so yourself is better than being told.

The ten kinds of evidence, in the order they persuade

Each line is something you can produce from records you already have, and each is stronger than the sentence most decks use in its place.

• Channel mix. Every deal in your history tagged to the channel that produced it, with the share each channel represents.
• Named referral sources. The specific people or organisations that repeat, rather than the count of introductions received.
• Founder relationships. Portfolio and non-portfolio founders who send you companies, which is the highest-quality channel in venture and the most credible to verify.
• Community position. A programme, event, publication, or group you run rather than attend, with its size and cadence.
• Conversion rates. Companies seen, companies taken to diligence, companies invested, per channel. The GoingVC piece on the questions limited partners ask, a practitioner blog from September 2025, uses a worked illustration of exactly this shape, six hundred companies reviewed and twelve investments. That is that article's example rather than a benchmark, and the point it makes is structural: measurable funnel data is what the answer to where do your deals come from is supposed to look like.
• Proprietary access. Something you can see that others cannot, which is rarer than the phrase suggests and should be dropped unless it is literally true.
• Repeat introductions. The same source producing more than once, which is the single cleanest signal of repeatability.
• Sourcing geography. Where the deals physically come from, and whether that matches the fund you are raising.
• Stage-specific access. Whether you see companies before an institutional round, which is the access that actually determines entry price.
• Decision history. The deals you saw and declined, with reasoning recorded at the time, which is what turns a funnel into evidence of judgment rather than of volume.

The sourcing funnel template

One row per channel, one column per stage. Blueprint's own template, and the discipline is that every cell comes from a record rather than an estimate.

• Channel. Named specifically: this operator community, this accelerator, these four founders, this publication, this programme.
• Companies seen. The count over a defined period, with the period stated.
• Qualified. Those that passed your first screen, with the screen written down.
• Diligence. Those you did real work on.
• Invested. Those you funded, with dates.
• Repeat rate. Whether the channel has produced more than once, and over what span.
• Dependency. Whether the channel works because of one person, and if so, who.
• Cost. What the channel takes to maintain in time or money, which is what makes it a strategy rather than luck.

Two rules keep the template honest. Count companies seen consistently, since a manager who counts every inbound email produces a conversion rate that means nothing. And show the channels that produced nothing, because a funnel with no failed channels has been curated rather than recorded.

What an allocator may reasonably expect to see

The expectation scales with what you have, and honesty about the sample matters more than its size.

• From a manager with an investing history: the full funnel above, at deal level, for a defined period, including passes.
• From an operator moving into investing: the channel map and the relationships, with an explicit statement that the investment conversion history is short, plus founders who will confirm the access is real.
• From a spinout: the funnel from the prior seat, with attribution settled and permission documented, which is its own page in this library.
• From everyone: a plausible answer to what happens to sourcing when the fund is deploying and you are also running an investment process, since sourcing that only works when you have spare time is not a plan.
• From nobody: a claim of proprietary deal flow with nothing behind it. It is the most common unsupported claim in venture fundraising and the cheapest for an allocator to test.

What limited partners are testing

Sourcing is where an allocator decides whether your returns could be repeatable rather than fortunate.

• Does the deal flow come from a mechanism, or from the manager's personal energy?
• Would the channels survive one partner leaving, or a year of the manager being unavailable?
• Do the conversion numbers reconcile with the number of positions the fund plans to build at the pace it plans to build them?
• Are the sources verifiable, meaning would the named people describe the relationship the same way?
• Does the funnel include the failures, or only the channels that worked?

What the funnel does not prove

Deal flow is not selection. A manager who sees the best companies in a market and chooses badly has an excellent funnel and a poor record, and allocators evaluate the two separately. The decision history column is what connects them, which is why it belongs in the funnel rather than beside it.

A funnel from a prior seat also does not travel automatically. Whether the channels come with you depends on whether they were yours or the firm's, and that is a question of attribution and, sometimes, of permission.
