Cybersecurity specialist Ploy raises £2.5m led by Osney Capital with Superseed
This article covers a funding round on 15 October 2025 for Ploy, a UK cybersecurity startup tackling identity-related breaches, founded by Jacob Prime. The company raised £2.5m in a round led by Osney Capital with participation from Superseed.
What does Ploy do?
Ploy is a cloud-based identity and access platform that manages user accounts across business applications. It makes access temporary by default and shows centralised visibility of who has access to which applications.
Why is Ploy useful?
Problem
Businesses face widespread identity sprawl across hundreds of SaaS apps, causing fragmented access and poor visibility. Spreadsheet-based tracking creates legal and security liabilities that leave gaps for attackers.
Solution
Ploy explains that it enforces just-in-time access, making permissions temporary by default to reduce risk and exposure. It provides centralised, real-time visibility and risk detection across SaaS apps, replacing spreadsheet-based access tracking.
How much did Ploy raise?
Ploy has raised £2.5m in a funding round led by Osney Capital, alongside existing backers. This makes it the 25th largest funding round in October 2025 (42 recorded). It ranks 326th of the year (514 recorded) in the Startupmag database, as of 15 October 2025.

In the funding announcement, Joshua Walter from Osney Capital said:
Identity sprawl has become a significant issue for organisations of all shapes and sizes, but particularly those with modern technology stacks; which often comprise hundreds, or even thousands, of SaaS applications. This breadth causes fragmented and distributed access and ownership of identity, without unified visibility or control, and is typically enabled using role-base access controls.

Who founded Ploy?
Jacob Prime is the founder of Ploy.
In the funding announcement, Jacob Prime explained:
With 80% of breaches now stemming from identity, boards are realising it’s the biggest area they need to prioritise in their security strategy. Spreadsheet-based access tracking is now a legal and security liability.
The company continued that organisations need real-time visibility into who has access to what to prevent attackers or regulators finding the gaps, and that Ploy addresses that problem.
Where is Ploy based?
Ploy is based in London, UK.
What sector is Ploy in?
Ploy operates in the cyber security sector. The sector protects computers, networks and data from unauthorised access and online attacks. In plain terms, it helps keep businesses and people safe online.
Key trends and challenges in Cyber security:
Identity-centred breaches
Identity related attacks cause most breaches, about 80% according to recent industry figures, so controlling access matters.
Identity sprawl from many SaaS apps
Organisations often use hundreds of SaaS apps, which fragments access and makes control hard.
Outdated access processes and regulatory risk
Manual tracking, like spreadsheets, increases breach risk and can create legal compliance problems with regulators.
