The Early Innings, with Mark Boggett (CEO of Seraphim)

In this episode of Valley of Depth, we sit down with Mark Boggett, CEO of Seraphim Space, to break down one of the biggest questions in the industry right now: are we still early in the space economy, or has the easy money already been made?

Mark has built one of the first dedicated space-focused venture firms, before the category became institutional. We discuss how the market has evolved from uncertain capital availability to a more mature ecosystem where large-scale funding is now expected and why that shift is unlocking a new phase of growth.

We cover:

• Why the space economy is still in its early innings of value creation
• How capital availability has transformed space investing over the last decade
• Seraphim’s strategy and why they avoid launch, space travel, and lunar markets
• The rise of European defense demand and the emergence of “neo-primes”
• How space companies are becoming real, profitable businesses
• Where the market may be overbuilt vs. underinvested
• Why vertically integrated constellations remain the core opportunity
• What the next phase of the space economy looks like
