Christina Qi on LinkedIn: “Risk is randomness that you can parameterize. Uncertainty is randomness… | 11 comments (2024)

What are some common misconceptions in your industry? Below are some irrelevant sentences that we hear often: 1. "I'm excited to apply my data science skills to Databento." - job candidate 2. "Market data is too small. I'll only invest if you gather the world's data, like satellite data, social media, and healthcare data." - investor 3. "Databento could use our AI services to enhance your offering." - startup 1 doesn't bother us, as it's exhausting applying to job after job, so candidates deserve leniency for not grasping what every company does. 2 indicates a lack of knowledge about market data vs. alternative data, the different audiences they appeal to, and the extreme differences in product, costs, and regulations between the two. 3 just no. The only AI startup I support is the one that eliminates all of the AI spam in my inbox every morning.

Sharing my thoughts on data startups since we're quoted in this front-page article today. - It sucks that startups are pitted as rivals when we try our best NOT to compete against each other. If we did, we would all die. Most users switch to Databento from a $10B incumbent. We rarely hear startup names during sales calls - it would suck (& be an omen for all) if we stole significant business away from any startup. - Believe it or not, Databento's enterprise customers don't switch over because of the price (despite having fair pricing: https://lnkd.in/gVMjvZvC). They switch over because our API and web experience are superior to the incumbent vendors. We consistently improve our uptime, latency, and technical support. - I cannot stress enough that targeting retail customers is a formula for failure, unless you get enough user data to sell it to HFT firms, as Robinhood does. That doesn't mean that we should shun retail folks, but rather that startups should think about how to scale from Day 1. Is the answer PLG? Scalable pricing? Better APIs? Better analytics? Cloud or on-prem delivery? - Whatever the innovation is, the answer should NEVER be "cheaper prices." "We're Bloomberg but cheaper," is a formula for failure UNLESS you offer a true technological innovation outside of price.

Random: Someone asked what celebrities I enjoyed meeting, so here's goes nothing. Some are awful, racist crazies, while others are normal and kind. Normal and kind: - Kim Kardashian: Met in Boston. Modest, understanding, low maintenance. (Who would've thought! Ye on the other hand...) - Natalie Portman: Met in Cayman at CAIS. So easy to talk to, was kind enough to say hi to my mom who is a huge Star Wars fan, was introverted on stage, was looking at the floor almost in embarrassment, 100% relatable and real. - David Blaine: Crazy but in a good way. Also met in Cayman at CAIS. Invited me on stage to sew his mouth shut Nightmare Before Christmas style if you know what I mean. There's no "trick" - it was him mutilating himself the entire evening. I almost threw up seeing the blood and guts on the string as he pulled the needle back and forth through his lips. He stayed afterwards and mingled with everyone, even though he could've flown away. He had punctured his hand with an ice pick for a "trick" so it swelled up like a balloon and an EMT had to take a look. I snuck a photo of him getting stopped by Cayman's TSA at the airport. Inspecting his magic up his sleeves? 🤣 One of my core life memories thanks to Anthony Cowell! It's inspiring and refreshing to meet someone down to earth who has every reason not to be. :)
