Who CB Insights is for

I started with the reader, not the data. CB Insights sells to four groups. Each pays for data the others don’t need, and each has a question they keep asking. I wrote the question down first, then went looking for a CB Insights number that answered it.

Investors

“What are the odds, and is the market turning?”

VCs and LPs. They pay for funding rounds, valuations and exits, and they want base rates to argue with.

CHARTS 01 · 02 · 04 · 06 · 07 · 09 · 11 · 14 · 16

Corporate development and M&A

“Who is buying, what does it cost, and how early?”

The people who buy startups. They pay for M&A data, acquirer lists and revenue multiples.

Corporate strategy

“Where is everyone else placing their bets?”

Strategy and innovation teams at big companies. They pay for business relationships, strategy maps and market maps.

Enterprise tech buyers

“Is AI paying off, and which vendors will last?”

The people picking AI vendors. They pay for buyer surveys, Commercial Maturity scores and vendor profiles.

Four rounds of design

Each round fixed what the last one got wrong.

1. A paragraph on the chart. Too much reading.
2. Clean, but in my colours, not theirs.
3. CB Insights’ colours, but one number against one.
4. Peter’s frame and key, many measures per chart.

One I couldn’t get right

Startup exits. The story is good: about 17 acquisitions for every IPO. But every way I drew it ended up as one big number against a tiny one, or a chart that needed explaining. Here are my three tries. I’d love to know how you’d show it.

Why would corporate development care?Most exits are acquisitions, and this quarter there were fewer buyers. Less competition for each deal you want.

– · For corporate development

100% stacks: the world’s exits against Europe’s

142 startups went public in Q3 2026. 2,353 were bought.

Chart below splits every exit into acquisitions, IPOs and SPAC mergers, for the world and for Europe.

Acquisitions: 2,353
IPOs: 142
SPAC mergers: 8
Europe: 988 exits, only 15 of them IPOs

What this means

About 17 acquisitions for every IPO. Founders picture ringing the bell. Most exits are a sale.

And M&A just hit a four-year low, down 22% on Q2. Fewer buyers, so the ones still buying have more choice.

Counts from a news summary of State of Venture Q3’26. The four-year low and the 22% fall are from CB Insights’ own page.

Most founders should plan for a buyer.

Waiting for CB Insights data

Seven ideas that need the CB Insights platform. The question and the chart shape are here, with blanks where the numbers go. I haven’t made any up.

What I cut

Five findings that are only one number against one other. Real, but a chart with two bars isn’t worth posting. Each says what it needs before it earns a chart.

Checked against Peter’s rules

Where I’m following them, and where I’m not yet.

RuleHow I did
More than one against oneThe best five carry four to twelve data points each. Anything with only two bars is parked.
His post structureAll of them: claim, chart below, numbers, what this means, caveats, close.
Sample in the subtitleEvery chart: “Data: N ... | period”.
One frame, annotatedSame header and footer on every chart. Key words boxed instead of a legend. Brackets, boxed notes and side notes point at the thing to see.
Facts vs guessesGuesses are marked. Worked-out numbers say so.
Cohorts and spreadsWeakest area. Only chart 09 is a cohort, and it’s from 2008 to 2010. Spreads need stage-level data.
Primary sourcesMost of the best five lean on one news summary of the Q3’26 report. I checked it wherever I could: its quarterly deal counts add up exactly to CB Insights’ own figure.
Every number and its source

Each chart has a CSV: label, value, unit, source, link, and whether the source is primary (CB Insights published it) or secondary (a news site summarised one of their gated reports). The full list is in SOURCES.md.
