Sources

The secondary sources we cross-check against

Founder Pulse is primary-source first. But we cross-check every claim against the best available aggregators, government data, and academic research. Here is the full list.

02 Why we still use primary sources

Aggregators have a 6-18 month lag on what founders are actually doing. By the time a trend shows up in PitchBook, it's been the talk of the founder Slack groups for a year. Founder Pulse exists to close that gap.
