The funds will develop the Razor Crest Mk-1, targeting orbital transport costs of $500–$1,000 per kg

Ethereal Exploration Guild raised $20.5 million in a Series A round.
The round was co-led by TDK Ventures and BIG Capital.
Other participants included Accel, Prosus, YourNest Venture Capital, BlueHill Capital, Campus Fund, and Riceberg Ventures.
The company will use the proceeds to develop its first fully reusable medium-lift launch vehicle, the Razor Crest Mk-1.
The Razor Crest Mk-1 is a 25-tonne-class launch vehicle.
It can carry up to 24.8 tonnes to low Earth orbit (LEO) and 10.8 tonnes to geostationary transfer orbit (GTO).
The company aims for an orbital transport cost of $500 to $1,000 per kg.

The global space economy is projected to reach $1.8 trillion by 2035.
The company competes with SpaceX in the reusable launch vehicle market.
The startup has collaboration agreements with IN-SPACe, ISRO, and other space agencies.
It has already manufactured an 80 kN upper-stage reusable engine named Pegasus.
