Agency

Diligence

The biggest under-priced risk in 2026 digital deals

Most diligence reports still treat AI search exposure as a footnote. For a meaningful share of digital businesses being bought today, it's the most important number on the page.

What an angel actually offers (and why most don't)

Most angel money is smart money in name only. Founders raising at pre-seed should know what to ask for — and what to walk away from.

Four-day week

Why the 100-day plan is more important than the diligence itself
