Seaborn Software Ltd secures £45.6k in pre-seed funding to digitalise maritime supply chains

London based B2B SaaS startup Seaborn Software Ltd has secured £45.6k in a pre-seed funding round. The investment values the maritime technology company at a post-money valuation of £2.8m.

Incorporated in March 2023, Seaborn Software focuses on modernising the ship supply industry. The maritime supply sector has traditionally relied on paper based, manual processes that are cost ineffective, heavily dependent on staff, and prone to long processing times. These inefficiencies frequently result in lost opportunities and reduced profit margins for ship suppliers.

To address these challenges, the company developed its flagship product: Supplier Assistant Software. The B2B SaaS platform digitalises the entire workflow for ship suppliers. It handles everything from requisition and inventory management to sub-supplier communication, invoicing, and final delivery. By automating these manual tasks, the software aims to accelerate processes, reduce staff dependency, cut operational costs, and create a permanent digital corporate memory for its users. The company currently operates from its London headquarters with a team of up to ten employees.

The latest pre-seed round, filed on 10 March 2026, involves an estimated £45.6k investment following an allotment of shares on 23 December 2025. This capital injection follows closely on the heels of a previous pre-seed tranche filed just weeks prior on 26 February 2026, which saw the company raise £22.8k. Both tranches were raised at the exact same £2.8m post-money valuation, indicating a structured rollout of early stage capital. The names of the investors participating in this round have not been disclosed.

Seaborn Software's funding arrives at a transitional time for the UK maritime technology sector. According to recent industry data, venture capital investment in UK and Irish maritime tech experienced a significant contraction in 2025, dropping by over 65 percent year on year to roughly £5m across just six rounds.

Despite this dip in private venture volume, the broader sector is receiving substantial structural support. In September 2025, the UK government announced a £1.1bn joint investment package for the maritime industry, aimed at modernising ports, supporting green technology, and driving digital innovation across coastal supply chains.

Furthermore, there is a growing appetite for software solutions that streamline legacy maritime operations. In January 2026, fellow London based maritime tech startup Spot Ship raised £1m to modernise global ship chartering using cloud based SaaS. Seaborn Software's successful pre-seed raise demonstrates that while overall sector funding may have cooled, investors remain willing to back targeted B2B platforms that offer clear efficiency gains and cost reductions in traditional, paper heavy industries.
