AVANTIS MARINE LIMITED
Company number 11496188 · Monitor this company
Executive summary
Avantis Marine Limited presents a medium-risk profile characterised by exceptional revenue growth but thin liquidity. The company has successfully transitioned from technical insolvency in 2019 to net assets of £5M by 2023, operating in a sector with strong regulatory tailwinds. However, cash reserves of approximately 2% of turnover, an anomalous PSC register showing two individuals each owning over 75% of shares, and the inherent risks of hyper-growth scaling require careful investigation before institutional commitment. The relationship with Avantis Group Investments Holdco Ltd and the composition of £5.9M in liabilities are particularly critical areas for due diligence.
