The VC Intake Stack in 2026 — How Top Funds Actually Process Deal Flow
Seven layers from sourcing to close — where applications die, why, and what to do about it.
Most founders treat fundraising as a black box. You send a deck. Something happens on the other side. Eventually you either get a meeting or you don't.
Understanding what actually happens between submission and decision — the VC intake stack — makes you dramatically better at fundraising. It tells you where applications die, why, and what you can do about it.
Layer 1: Sourcing
Before any evaluation happens, a fund has to find you. Funds source deals from four primary channels:
1. Warm referrals. The highest-quality channel. Intros from portfolio founders, co-investors, lawyers, and bankers carry implicit pre-screening. A partner's trusted network vouching for a company is worth 10x a cold application.
2. Inbound applications. Funds receive hundreds to thousands of cold inbound applications per year. These go through the highest attrition in the funnel — most are filtered by an associate or analyst before any partner sees them.
3. Proprietary sourcing. Top funds proactively hunt for companies using databases (Harmonic, Crustdata, Specter), LinkedIn signals (founding-engineer hires, ex-FAANG founder title changes), GitHub star velocity, and scout networks. These companies often get contacted before they're officially fundraising.
4. Event-based sourcing. Demo days, conferences, and hackathons surface companies in concentrated form. YC Demo Day, a16z Speedrun Demo Day, and Techstars Demo Days are the highest-signal events.
PitchProtocol's position in this layer: Structured applications submitted via PitchProtocol are routed directly to partner-level evaluation at thesis-matched funds — bypassing the inbound triage filter.
Layer 2: First-Pass Filtering
Once a company enters a fund's pipeline, the first pass is almost always mechanical:
- Stage: Is this the right stage for our fund? (Pre-seed when we only do Series A = instant pass)
- Sector: Is this in a category we invest in?
- Geography: Is this in a market we cover?
- Check size: Does the round size match our typical check?
At larger funds, this first pass is done by analysts or, increasingly, by AI tooling. At smaller funds, it's often the partner opening email.
Attrition at this layer: Very high. A significant portion of inbound applications are filtered here — not because the company isn't good, but because the fit criteria don't match. The problem: filtering is often done with incomplete information because the application doesn't clearly communicate stage, sector, and metrics.
Layer 3: Partner Review
Companies that pass the first filter reach a partner's desk. This is where genuine evaluation begins.
What a partner looks for in 3–5 minutes:
- What does this company do? (Is the description clear?)
- Why is this market large? (Do I believe in the size?)
- Who is the team? (Any signals I recognize?)
- What are the metrics? (Any headline number that creates urgency?)
- Why now? (What has changed that makes this timely?)
If the partner can't answer these questions from the initial material in 3–5 minutes, the company usually doesn't advance. Not because the company is bad — because the material didn't communicate clearly enough.
Attrition at this layer: High. Most companies that pass the mechanical filter still don't get first meetings.
Layer 4: First Meeting
First meetings are typically 30–60 minutes. The goal from the partner's perspective: validate the initial hypothesis and decide whether to go deeper. The questions they're answering:
- Is this team credible and coachable?
- Is the insight genuine, or is this a trend-chaser?
- Do the metrics hold up under questioning?
- Can I see a path to conviction, or does this have too many unknowns?
What kills deals at first meeting:
- Founders who can't answer basic questions about their metrics
- Market sizing that falls apart under scrutiny
- Team gaps with no plan to address them
- Defensive responses to hard questions
What advances deals:
- A founder who knows their business better than the VC
- Specific insight about the market that shifts how the partner thinks
- Traction that creates urgency on both sides
Layer 5: Diligence
Diligence is the structured process of validating everything that was claimed in the first meeting. The sub-layers:
Customer references: 6–12 calls asking about product quality, expansion intent, and founder character
Financial review: Detailed model review, cohort analysis, burn validation
Technical diligence: (For AI, deep tech, infrastructure) Code review, architecture review, IP assessment
Competitive analysis: How does the fund see the competitive landscape vs. how the founder sees it?
Partnership alignment: Can the lead partner get the rest of the partnership aligned? This is often the hidden bottleneck.
Attrition at this layer: Moderate. Companies that enter diligence close 40–60% of the time, depending on the fund.
Layer 6: Investment Decision
At most funds, investment decisions require partnership consensus — all partners voting on a deal (Benchmark model) or a majority (most other funds). The lead partner has to convince colleagues who haven't spent time with the company.
This is the stage where the investment memo matters most. It needs to answer:
- Why this company?
- Why now?
- Why us (as investors)?
- What does success look like in 5 years?
- What are the key risks and how do we mitigate them?
The hidden bottleneck: Partner champion vs. partner skeptic. Every company that gets killed at partnership has a champion who believed and a skeptic who prevailed. Understanding this dynamic helps founders: make sure more than one partner is engaged with your company before the partnership meeting.
Layer 7: Term Sheet to Close
Once the partnership approves, a term sheet is issued. Then:
- Negotiation on terms (valuation, pro-rata rights, board composition)
- Legal close (subscription agreements, side letters)
- Wire
This layer typically takes 3–6 weeks and is mostly lawyer-driven once the business terms are agreed.
Where Most Applications Die (And How to Fix It)
| Layer | Where applications die | Fix |
|---|---|---|
| Sourcing | Not reaching the right fund | Thesis-match before outreach |
| First-pass filter | Stage/sector mismatch | Communicate clearly in the first line |
| Partner review | Unclear value prop in 3 minutes | Sharpen the one-liner and headline metrics |
| First meeting | Can't answer hard questions | Know your numbers cold |
| Diligence | References don't convert | Pre-brief references; clean data room |
| Partnership | Champion can't convince others | Get multiple partners engaged early |
How PitchProtocol Changes the Stack
PitchProtocol is built to compress layers 1–3 and give founders a clear path to layer 4 (the first meeting) faster.
- Layer 1: Your application routes directly to thesis-matched funds — no cold inbound filter
- Layer 2: Mechanical filtering is handled by the platform before your application reaches any partner
- Layer 3: Your application arrives with independent research already completed, and fund-specific questions pre-answered — partners spend time on judgment, not information gathering
The result: less time in the funnel before the first meaningful conversation. Apply to the First 100 Founders Cohort →
Frequently Asked Questions
How many funds should I pitch simultaneously?
For Series A: 15–25 funds in simultaneous process is typical. For seed: 10–15. Fewer than 10 creates concentration risk; more than 30 is hard to manage.
What's the average conversion rate from inbound to investment?
At top-tier funds: roughly 0.5–1% of cold inbound reaches an investment. The rate for warm intros is dramatically higher — typically 5–15%.
How do VCs decide who to meet from inbound?
Primarily on two signals: clarity of communication (can I understand what this company does in 30 seconds?) and headline traction (is there a number that creates urgency?). Everything else is secondary at the first-pass stage.
Does it help to follow up on a cold application?
One follow-up after 1–2 weeks is acceptable. More than that crosses into being pushy and can damage the relationship before it starts.
