Ask your agent how the last quarter went and it calls win_loss: counts, values, win rate, average cycle length, and the loss reasons your reps recorded. Ask about one account and account_lookup returns the people, deals, subscriptions, and live MRR in one view.
Deal reviews stall when nobody can see the whole account: who is involved, what else is open, and whether they are already paying.
