Company structure and ownership

Understand how new companies are set up, so you can make informed decisions as your spinout ​or startup takes shape.

Laying the foundations

How your company is structured matters. It shapes everything that follows: who owns the company, how decisions are made, and how future growth is supported.  

We work with you to make sure your foundations are clear, fair, and aligned with University policy, while remaining attractive to investors and future team members.

Shareholding models

Companies from the University of Oxford are typically formed using one of two legal structures. The right choice depends on your goals, funding plans and whether the company is primarily commercial or mission-led.  

Companies Limited by Shares (CLS)

This is the model followed by most Oxford spinouts. In a CLS: 

  • The company is owned by shareholders 
  • Financial returns are linked to shareholding size 
  • Shareholders appoint a board of directors 
  • Directors have legal responsibility and personal liability 
  • Day-to-day operations are led by a management team, typically headed by a CEO 

CLS structures are well understood by investors and are used for the vast majority of commercial spinouts. 

Companies Limited by Guarantee (CLG)

CLGs are not attractive to traditional venture investors, but can be a good fit where impact, rather than financial return, is the primary goal. In a CLG: 

  • The company is owned by members, not shareholders 
  • Members have equal voting rights 
  • Members appoint a board of directors 
  • The directors and management team have similar responsibilities to those in a CLS  
  • The company cannot be sold and has no equity 
  • Profits are typically reinvested into the mission 

The University becomes a member of CLG spinouts, and at least four additional members are required at formation. 

Founding agreements and equity 

Spinouts

Oxford University has a standardised ​Spinout Equity Policy, designed to: 

  • Provide upfront clarity for Founders and investors 
  • Reduce time-consuming negotiations 
  • Support Founder-led, investable companies 

In most cases, founding equity is split (before any investment) as 80% founding team / 20% University.

In some specific cases, the founding equity is split 90% founding team / 10% University. This is only for spinouts with no patented or patentable IP, who are either qualifying software companies or have had no University support. 

If the company secures investment, the investor’s shares reduce the fraction owned by the original shareholders - this is called ‘dilution’. University shares are not protected from dilution, and will be affected in the same way as Founders and management. 

For spinouts from the Mathematical, Physical and Life Sciences Division (MPLS) or Medical Sciences Divisions (MSD), the University’s founding equity is shared with Oxford Science Enterprises (OSE) under an existing agreement. 

Dividing equity within the Founding team

Founders also need to agree how their share of equity is divided between themselves and any external managers who join early. 

While there’s no single formula, equity allocation should reflect: 

  • Contribution to creating the idea and business opportunity 
  • Ongoing roles and responsibilities 
  • Time commitment  
  • Personal risk, especially for Founders joining the company full-time 

Shares in the company are often used to incentivise management teams and early hires. If you want to create an option pool from which to draw these shares then this allocation will need to be agreed too.   

We can help you think through these decisions and align them with best practice and investor expectations. 

Startups

As startups don’t use University-owned research, you can build and run the company just like any other private company. But if you’re part of the Incubator, we’ll take a 5% equity stake once the company joins the Phase 2 programme – typically (but not always) at the first round of investment. This allows us to support you with anything from product development to building connections and helping you find your own offices as your company matures.  

Board structure and leadership

Strong governance is essential as your company grows. Understanding the roles of the board, directors and management helps ensure clear accountability, effective decision-making and investor confidence from the outset. 

In a CLS company, the board of directors is responsible for: 

  • Governance and oversight
  • Strategic direction
  • Appointing and supporting senior management 

A typical board may include: 

  • Academic Founders
  • An external or Founder CEO
  • University representatives
  • Investor-appointed directors
  • Independent non-executive directors 

While not all Founders need to stop their University work, investors will usually expect at least one Founder to join the company full-time to manage day-to-day operations. 

In CLG companies, directors are appointed by the members, but board responsibilities are broadly similar.

Supporting the next generation of innovation

When Oxford University companies succeed, the benefits extend beyond financial returns. Revenue from licensing, consultancy and company exits is shared with researchers, the departments, and the broader University. 

This helps support future research, innovation and the creation of new companies – creating a cycle in which today’s successful ventures help fund the next generation of Oxford University breakthroughs.
