There's roughly $631,800 of expansion ARR sitting in your existing base — cheaper to win than any new logo. A targeted cross-sell play against the 585 single-product accounts is usually the highest-ROI pipeline you have.

Expansion converts best when tied to usage signals — prioritise accounts already bumping the limits of their first product.
