Why Diligence Takes Longer Than It Did in 2021
Diligence got slower in a year when venture deployment hit a record. Global startup investment reached roughly $510 billion in the first half of 2026 (Crunchbase News), yet by most founders' accounts the time from first meeting to closed round is longer than it was in 2021.
The usual explanation is caution. The better explanation is throughput - and it points at a fixable problem rather than a market mood.
Key takeaways
- Diligence lengthened while deployment rose. Caution alone does not explain that combination.
- In our view, partners are reading more companies per decision than they were in 2021.
- Most of the reading cost is reassembly, not analysis: finding the number, checking it is current, working out what it was measured against.
- Cross-border deals amplify the effect: no shared network, no shared legal defaults, no shared format.
- This is an infrastructure problem. It does not resolve when rates fall.
The numbers
A seed round in 2026 runs roughly three to six months end to end. Within it:
| Phase | 2021 (typical) | 2026 (typical) |
|---|---|---|
| First meeting to term sheet | 3-6 weeks | 6-10 weeks |
| Formal diligence on a priced round | 1-2 weeks | 2-4 weeks |
| Term sheet to wire | 2-3 weeks | 3-4 weeks |
Meanwhile, per Carta, the seed-to-Series A gap stretched past two years and the graduation rate roughly halved. Detail in the graduation problem.
The caution explanation, and its limits
The standard story: after 2021, investors got burned, LPs demanded discipline, and diligence tightened accordingly.
There is real truth here. Diligence standards genuinely rose. Reference checks that were skipped are now taken. Metrics that were accepted are now verified.
But caution alone predicts lower deployment, and deployment hit a record. Much of that record sits in a small number of very large AI rounds, so it is more dollars rather than more deals. Even so, an early-stage market that is both well funded and slow needs more than caution to explain it.
The throughput explanation
Consider what an early-stage partner's week actually looks like now.
Deal volume rose. Capital formation globalised, so companies arrive from more geographies. Remote-first means more of the process happens without a meeting that would have compressed six questions into one conversation. And the graduation squeeze means more companies are in market for longer, so the same company appears in the funnel repeatedly across an extended period.
Net effect, in our judgement: a partner is evaluating more companies per investment decision than a few years ago.
Every additional company costs reading time. And here is the part that matters: most of that time is not analysis.
Reassembly is the real cost
Break down the twenty minutes a partner spends on an unstructured company:
| Activity | Share of time |
|---|---|
| Finding where the information is | ~30% |
| Working out whether it is current | ~15% |
| Normalising metrics into comparable units | ~25% |
| Actually forming a view | ~30% |
Seventy per cent of the reading cost is reassembly - reconstructing a comparable picture from an idiosyncratic artefact. The deck is in one format, the model in another, the metrics defined differently from the last company, the traction slide three months out of date.
None of that is diligence. It is data entry performed by an expensive person.
Multiply across a funnel of several hundred companies a year and the throughput ceiling is obvious. When a partner is at capacity, every company waits longer, and the founder experiences that as "diligence is slow".
Cross-border amplifies everything
The regional shift makes this materially worse. The US share of global venture fell from roughly 83% in Q1 2026 to about two thirds in Q2, with Europe posting its strongest quarter in four years and Asian markets accelerating (Crunchbase News, H1 2026).
More deals now cross a border, and cross-border deals lose every shortcut at once:
- No shared network, so reference checks take a week instead of a day
- No shared legal defaults, so document review is real work rather than a template check
- No shared timezone, so each round trip costs a day
- No shared format, so the reassembly cost applies with nothing familiar to anchor on
An investor three time zones away in a different legal regime is entirely dependent on the quality of your record. They will not chase you for what is missing. They will deprioritise.
What actually shortens it
For founders, in order of impact:
- A complete record before you start. Every question answered by the record instead of by email removes a two-to-four day round trip. Thirty of those, even with many running in parallel, add up to weeks.
- Same-day responses. During diligence this is the standard, and it is only achievable if the data is already retrievable.
- Pre-empt the standard requests. Cap table reconciliation, IP assignments, metric definitions, references. All of them are asked for every time.
- Land a lead early. The lead creates the deadline that makes everyone else move.
For investors:
- Structured intake, so screening costs ninety seconds rather than twenty minutes.
- A proportionate diligence list, sized to the cheque. The pre-seed version is a week, not a month.
- Verify one metric, not all of them. Pick the one the thesis depends on.
The part that will not fix itself
Rates will move. Sentiment will shift. Neither changes the fact that a partner reading several hundred companies a year, each in its own format, has a hard throughput ceiling.
That ceiling is set by the absence of a standard for how a private company presents itself. Public markets solved this decades ago by mandating standardised filings, which is why any analyst can compare any two listed companies in minutes. Private early-stage markets accept a PDF and a spreadsheet, and then treat the resulting slowness as a feature of the asset class.
It is not a feature. It is a missing standard, and it is the thing worth building.

Frequently Asked Questions
Two to four weeks of formal diligence on a priced seed round, inside a three-to-six-month end-to-end process.
Investors are reading more companies per decision, in more formats, from more geographies. Most of the added time is reassembly rather than analysis.
Yes, by removing round trips. Each unanswered question costs two to four days of calendar time.
Partially. The throughput constraint is structural and does not resolve with sentiment.
