What we are solving

Industry Pain Points

We know that 80% of vessels have inaccurate inventory data, costing the shipping industry over $2 billion dollars every year.
This inaccuracy makes it hard for seafarers and engineers to carry out their day-to-day work onboard the vessels, wasting thousands of hours per year – time that could be freed up to conduct more value-added work.

80% inaccurate inventory data

including spares not on board but in the ERP system, and vice-versa

100+ days per year wasted per vessel

due to inefficient processes, looking for lost spares and doing manual reconciliations

30% excess spares held on board

due to a lack of understanding of safety levels for each spare part onboard, vessels are overstocked

$50K+ yearly in missed procurement opportunities per vessel

due to urgent orders surcharges and inability to procure proactively or in bulk without accurate data

Our solution

Designed for seafarers by seafarers after spending over 1000+ hours onboard vessels
