WHY PLUSUM

Close the gap.
Keep the value.

Most marketplaces leave a deal to die when buyer and seller disagree. Plusum gives the transaction one intelligent chance to converge.

01 / NEGOTIATE

Every counteroffer has a strategy.

The agent reads intent, offer history, urgency, and market context—then chooses the smallest useful concession.

02 / CONTROL

Give it goals.
Never your judgment.

Floors, term limits, inventory rules, and escalation paths stay deterministic.

03 / LEARN

A better agent after every deal.

Turn outcomes into measurable strategy—not another unread chat transcript.

BUILT TO BE TESTED

Performance,
not personality.

Each release is evaluated against adversarial negotiation scenarios: hidden customer profiles, changing market conditions, and hard policy constraints.
