Key takeaway

The Bank joined a Temasek-led round using pension capital, its fourth British Growth Partnership position.

The British Business Bank put $25m into PhysicsX on 30 July, the fourth investment from British Growth Partnership Fund I since its £200m first close ¹. Temasek, Singapore's state investment company, led the round, with M&G Investments also participating. PhysicsX builds simulation software for engineers designing physical products, and has doubled recognised revenue and passed 300 staff.

PhysicsX has appeared in this topic before. Temasek led a $300m Series C at a $2.4bn valuation in June , with no UK state vehicle contributing a pound. This time the Bank joined through the British Growth Partnership, which pools pension money and invests it alongside the Bank's own balance sheet. The partnership's other three positions are Wayve, Elliptic and Draig Therapeutics, and none has appeared in this topic before. Ian Connatty, the partnership's managing partner and the Bank's deputy chief investment officer, describes the fund as "created to connect pension funds with the UK's fastest growing companies".

That description names a real constraint rather than a slogan. A pension scheme cannot underwrite a single venture position on its own, because the diligence cost per pound invested is prohibitive and the trustees end up carrying exposure they have no way to price. Buying into a pooled vehicle that does the diligence once, across a portfolio, converts an unmanageable risk into a line item a trustee board can sign off. Whether British schemes take that conversion at scale is the question this cheque tests; PhysicsX would have priced with or without a British name on the round.

Deep Analysis

In plain English

PhysicsX is a British engineering-software company. It just raised money in a round led by Temasek, the Singaporean government's investment arm, with the asset manager M&G also taking part. The interesting part is where a small piece of that money came from: the British Business Bank's British Growth Partnership, a fund built specifically to let British pension schemes put money into fast-growing UK companies without each pension fund having to do that difficult, expensive work itself. This is only the fourth company the Partnership has backed since it started with £200m. In effect, ordinary British pension savings went into a British company, in a funding round mostly priced by Singaporean state money, through a vehicle designed to make that kind of investment simpler for pension trustees.

What could happen next?

Meaning
The British Growth Partnership's co-investment model lets pension capital reach a $25m slice of a venture round it could not underwrite alone.
Risk
Four positions since a £200m first close is a slow deployment pace for a fund meant to demonstrate pension co-investment at scale.

Source Landscape

This story draws on neutral-leaning sources

PhysicsX's Series C itself was covered in this briefing series in June ; what changed in this window is the pipe the British Business Bank used to join it, not the underlying deal.

A pension scheme cannot underwrite a single venture position directly, the diligence cost per pound invested is prohibitive and trustees would carry concentrated risk they cannot price, so the Partnership takes a limited-partner slot in a pooled vehicle that performs that diligence once and spreads it across several positions.

PhysicsX had already doubled recognised revenue and passed 300 staff before this round closed, meaning the $25m from the Partnership was not needed to make the round happen; it tests the co-investment mechanism rather than fills a funding gap.

Consensus view: Ian Connatty, managing partner of the British Growth Partnership and deputy chief investment officer of the British Business Bank, describes the fund as built to 'connect pension funds with the UK's fastest growing companies', and PhysicsX, its fourth position since a £200m first close, fits that stated mandate: Temasek led the round, with British public money co-investing alongside Singaporean state capital rather than replacing it.

Counter-view: No published critic has assessed whether the fund-of-funds model actually reaches pension savers at scale, rather than a small number of large institutional schemes able to commit to a pooled vehicle. The unattributed case for caution: four positions since a £200m first close, Wayve, Elliptic, Draig Therapeutics and now PhysicsX, is a slow deployment pace for a vehicle meant to prove a model other pension funds might replicate.

Key tension: Whether the British Growth Partnership's structure genuinely lowers the barrier for pension capital to reach venture-stage companies, or whether it mainly gives the Bank co-investment access to rounds it could not otherwise join.

This Event

Pension cash goes into PhysicsX round

The British Growth Partnership is the mechanism by which UK pension schemes can hold venture positions they could never underwrite alone, and this cheque is its fourth live test.

Different Perspectives

Nscale and Open Cosmos

Nscale chose the New York Stock Exchange for its listing on 18 September, putting Britain's largest AI infrastructure bet to American public investors rather than British ones. Open Cosmos took the opposite route four days earlier, raising nine figures from an all-domestic syndicate on five years of profit, evidence that staying is possible when the balance sheet allows it.

Dame Chi Onwurah and the Science, Innovation and Technology Committee

Committee chair Dame Chi Onwurah wrote to government on 7 September asking how Matt Clifford's conflict at ARIA arose and what safeguards protect its governance, and expects a detailed response. Her question has not yet been put to the Sovereign AI Unit, whose own chair sits at a venture capital firm while overseeing state AI equity.

The Entrepreneurs Network

The Entrepreneurs Network's founder survey found 65% say Britain is easy to start a business in but only 14% say it is easy to scale one, with 82% negative on tax and 74% finding investment hard to access. On this reading the constraint is regulation and tax, not the capital-vehicle design the state keeps adjusting.

New Economics Foundation

The New Economics Foundation argues fiscal accounting rules, not political will, cap what Britain's state capital vehicles can do. Matching the KfW and Bpifrance benchmark of 1% of GDP would need the National Wealth Fund to deploy roughly GBP21bn a year by 2028-29, about four times its current capacity.

Competition and Markets Authority

The CMA's 8 September report on public procurement asked whether Britain's roughly GBP400bn state-spending system is built to grow high-potential firms rather than simply widen SME participation. Its Recommendation 5 calls for a dedicated frontier-technology procurement framework, an official acknowledgement that today's design may serve the wrong target.

Highland Europe

Highland Europe, the growth-equity firm behind a €1bn-plus fund, took €65m from the British Business Bank into its Technology Growth Fund VI on 30 July via British Patient Capital. For a Geneva-based growth investor, the Bank's cheque is routine cornerstone capital, unrelated to which Whitehall department currently claims to sponsor UKRI.
