Your stack today
Your tools each see part of the stem. Stemline sees all of it.

Threads hold the RFQ, but the stem lives nowhere — context is lost when the inbox moves on.
Communications sit on the deal and the company — searchable, linked to margin and follow-up.

Built for trust
Your book stays yours.
Brokers live on relationships and margins. Stemline is built so neither leaves your firm.
- Nothing sends without you. The agent drafts; you approve every quote and email.
- Managers stay in control. Multi-seat desks can require approval for pipeline changes.
- Nothing disappears. Records are never hard-deleted.
- Your data is walled off. Each firm’s data is isolated at the database level.
Private to your firm
- Contacts, PICs, and pipeline notes
- Communications and negotiation history
- Supplier relationships and coverage
- Fixtures, margins, and quotes in flight
Shared industry reference
- Ports and UN/LOCODE taxonomy
- Fuel grades (HSFO, VLSFO, MGO, …)
- Public bunker indices and FX
- Vessel registry facts by IMO
