Our Philosophy
Hacking To Win
Most startups don’t fail for lack of ambition, they fail because they run out of time and money. Venture timelines move too slow. Traditional capex is too heavy. R&D loops spiral endlessly. At CiRi Ventures, we believe survival demands urgency. Thriving means building like it’s life or death. Hacking isn’t chaos. It’s precision under pressure.
Deployment Beats Theory
We back what is real. EBITDA-positive deployment comes first, driven by actual traction.
Capital is Scarce
We compress years into months by aggressive financial recycling and capex hacks.
We encourage founders to embrace failure, pivot fast, and think ecosystem-first.
Precision Under Pressure
Hacking is not “do more”—it’s doing the one thing that unlocks the 10x.

From The Founders We Back
Don't just take our word for it. Here's what our portfolio founders say about building with CIRI Ventures.

"'Hacking to Win' is real. We compressed a two-year roadmap into nine months because they helped us focus on the one thing that mattered: deployment."
CEO

"They don't just open doors; they walk through them with you. The intros to their network of family offices and corporate partners were key to securing our first major contracts."
Founder

FAQ
Frequently Asked Questions
Here are the top questions our clients ask before getting started.
What makes CIRI Ventures different from a typical VC?
We are operators first. Unlike traditional VCs, we provide "embedded execution," not just advice from the sidelines. Our "Hacking to Win" philosophy means we get deeply involved in your operations—from capex hacking to supply chain strategy—to accelerate your path to real-world deployment and EBITDA in months, not years.
What do you look for in a founding team?
We back doers, not just dreamers. We look for founders who thrive on intensity, data, and discipline. The ideal team is deeply technical, customer-obsessed, and has a relentless drive to build and deploy. Founders who have "spent 50,000 hours with zero in the bank" understand our approach instinctively.
What does "hands-on support" actually mean?
It means we're in the trenches with you. This can range from helping you reduce opex and extend your runway, to fast-tracking B-sample delivery to top-tier customers, to advising on global manufacturing strategy. With our portfolio company Natrion, for example, we conducted 39 targeted interventions to help them scale production from 100k to over 2M sqm/month.
What is your typical investment process?
Our process is built for speed and clarity. It starts with your pitch, followed by an initial screening call. If there's a fit, we move quickly into deep diligence where our operational team engages with yours to understand the technology and business. We pride ourselves on a transparent and fast-moving process, because we know that for a startup, time is the most valuable resource.
Do you lead investment rounds?
We are flexible and can lead, co-lead, or participate in rounds from pre-seed to Series A+. Our primary goal is to ensure the round is structured for the long-term success of the company. We often leverage our network to bring in strategic corporates, family offices, and other VCs to create a capital stack that is aligned with your mission.
