IIT, chalkboard, zero slides
A 22-year-old at IMC gets paid $500,000 in year one for exactly one skill. Not picking winners. Seeing every trade as a full spread of outcomes, each one with its own odds attached.
Her name is Prabha Sharma. She teaches this exact skill on a bare chalkboard, for free, in a lecture almost nobody outside that room has ever watched.
Most people see a trade as a coin flip. Win or lose. Nothing else.
You already think this way about your own trades, don't you.
That's the mistake. A trade is never just win or lose. It's a spread of outcomes, each with its own odds and its own payoff attached before a single dollar moves. The formula for this is called the binomial distribution, and it's far simpler than it sounds.
Here it is:
P(X = k) = C(n,k) × p^k × (1-p)^(n-k)
n = how many bets you take
p = your real win probability on each one
k = how many of them you actually want to win
Try it yourself right now. Say you have a genuine 55% edge (p = 0.55) and you take 10 trades (n = 10). What's the actual chance you win at least 6 of them?
Plug in k = 6: P(X=6) = C(10,6) × 0.55^6 × 0.45^4 ≈ 23.8%
Add that up across every value of k from 6 to 10, and your real odds of winning at least 6 out of 10 land around 47%. Just under a coin flip, with a genuine edge in your favor.
Sit with that for a second. A 55% edge does not feel like 55% once you actually run the math over a small number of trades.
This is the exact formula that decides how much to risk on any single bet, once you actually know your edge. Sharma builds the whole thing from zero, in notation simple enough for a complete beginner to follow every step.
Wall Street pays $500,000 a year for this one skill. An IIT professor already gave the entire thing away, for free, on a blackboard nobody bothered to watch.IIT, chalkboard, zero slides

CRM has always been weird.
Humans do the work → then manually update the CRM about the work.
Lightfield is flipping that model.
Instead of asking reps to keep the CRM updated, it builds the customer context from calls, emails, Slack, LinkedIn, etc.
Then agents can actually work from that context.
This feels much closer to what an AI-native CRM should be.
$47M Series A led by a16z is a pretty strong signal too.
