Episode 113: Rainbow Crops: Giacomo Bastianelli on Treating Every Investor as "One Shot," Selling Without Selling, and Fundraising as a Probability Matrix

In this episode, I welcome back Giacomo Bastianelli, Co-Founder & CEO of Rainbow Crops — and one of the first founders to return to the podcast, because eighteen months ago we were talking about his pre-seed, and today he's just closed a €9.7M seed round plus a $7M grant from the Gates Foundation. Rainbow Crops is a VIB spin-off out of Ghent developing next-generation crop genetics, combining precision breeding, multiplex genome editing, and AI to tackle the complex, multi-gene traits — yield, stress resilience — that a single-gene approach can't touch. Giacomo walks us through how he ran the raise like a disciplined operator: preparing the seed materials before the pre-seed even closed, building a manually curated 60-name investor funnel in Trello, and treating every first interaction as a single shot he couldn't waste. He explains why his lead investor, Turin-based LIFTT, was nowhere on that list — and why doing the work is exactly what opens you up to that kind of serendipity. Along the way we get into a genuinely different take on persuasion for deep tech: honesty as a sales strategy, presenting risk as a probability matrix, and why the best salespeople never actually sell.

🎧 Listen to the full episode to hear why Giacomo built his own pitch deck instead of hiring an agency (and when a "polisher" makes sense), how he structured a results deck that lands for both non-technical investors and PhD experts, why you should pitch your tier-two and tier-three investors first, how he used a probabilistic model to talk investors through regulatory and patent risk, and the "tip of the iceberg" principle behind a deck that could survive real due diligence.

RAINBOW CROPS is built on a hard genetic truth: the traits that matter most in agriculture — yield, drought tolerance, climate resilience — are almost never controlled by a single gene. They emerge from networks of genes interacting at once, which is precisely why they've resisted decades of conventional breeding and single-edit biotech. Rainbow Crops attacks that complexity head-on with its Trait Foundry™ platform, pairing multiplex genome editing with AI and automated phenotyping to search enormous combinatorial spaces and engineer the multi-gene traits that older tools simply can't reach.
