AI made execution free. Knowing first is the whole game now.

The advantage goes to whoever is first into the right conversations, most often. Fundz stacks those odds: more of the moments that create demand than anyone else catches, as they happen, matched to who you sell to, with the decision maker to call. Now it answers in Claude too: ask for today’s leads and who to reach, then write the note in the same window. Not a feed. Not a list you rent. A system for being first.

Description

CSIRO has quadrupled its backing for Main Sequence's Atmosphere pre-seed fund to $20 million. The funding has increased from $5 million allocated in fund 3 to $20 million in fund 4, which Main Sequence is preparing to raise later this year. The Atmosphere fund was launched two years ago as an experiment to turn promising Australian science into venture-backed companies. The model, described as 'venture buildability,' helps scientists who understand their technology develop the commercial machinery around it.
