The problem

Your largest operating cost is still bought by phone and email

Today, every inquiry is spread across phone calls, emails, texts and manual entry into your ERP. Offers arrive in different formats, on different devices. The best one is easy to miss, and the record of why you chose it lives in someone's inbox.

Five channels. No single record.

Trusted by industry leaders

One platform, three pillars

One platform runs the entire procurement workflow

01 Market Research

Know the market

Know the port before you send the inquiry. Market research, weather conditions, bunker delays, port restrictions and fuel quality history across 450+ ports. Compare on cost and energy content, because the cheapest tonne isn't always the cheapest fuel. Indication prices are also available via API.
