    *petition agents cloud seeding*
    *Mass poisoning isn’t a solution for humanity*
    *It’s designed to poison our species*

    *Nothing You make will better our future*

    *To convince the next generation this is all for the best of us all is just a continued dismissal of our rights* .

    *This spokesperson looks like a robot made 20 years ago* .

    Nice and sounds good if everyone is perfect and rainbows and unicorns exist. In reality, the major top issue is with very advanced technology getting in the hands of the corrupt and misinformed to cause non-repairable damage to the future of the planet.

      its not individuals, its individuals taking advantage of a poorly —-designed— system. A more intentional design to public space, work, food, ect can lead to mass results. We have to put in hard work to make living sustainably effortless.

    I know it’s hard to go deep in less than 10 minutes, but this is a very shallow video, full of marketing-style buzzwords that don’t mean anything without context or details.
    I’m honestly unsure what the point of this video is, other than “Modern problems need modern solutions! My team exists to explore these solutions!”. It feels like a sales pitch for investors.

      Except society mandates function for people to live. Humans have to work in numerous disciplines to sustain this system. That’s why lockdowns have had catastrophic effects on world economies & caused mass unemployment due to reduced productivity.

      You cannot just print endless money. Problems must be solved instead of being exaggerated & delayed. People have to return to normal quickly.

There is no such thing as the perfect pitch. But you can get close by implementing a few research-backed methods to your delivery, deck, and message.

In this episode of Build Mode, host Isabelle Johannesen sits down with Dr. Eike Gerhardt, who has aPhD in pitching and spent nearly a decade studying the science of startup pitching before starting Autopoiesis Sciences. And he’s joined by Demetri Maxim, co-founder and CEO of Nephrogen, who came in second at TechCrunch Startup Battlefield 2025.

Together, they break down Demetri’s actual Startup Battlefield pitch to unpack what worked, what could be improved, and what research tells us about how investors respond to founders. Eike explains why credibility signals matter, how technical founders can simplify without oversimplifying, and why Q&A should be treated as a second pitch. Demetri shares how he learned to explain complex biotech to generalist investors, how redesigning his deck changed his confidence onstage, and what he would do differently today.
They also explore how body language and authenticity affect a pitch, how investor questions can reveal bias, and how founders can use AI to prepare for difficult Q&A.
