CityFibre has $3.1B on record. The latest round is a $3.1B Growth (July 2025). Size your own round against the evidence it must buy, not against the stage letter.
Key takeaways
- Round size should be derived from the evidence the next investor needs, not from the stage label.
- Named participants on a record tell you which funds write at this size and stage.
- Plan the raise timeline backwards from your cash-out date, with a third added for slippage.
Not every round gets a letter. Growth capital is negotiated against different evidence: retention, unit economics and a credible path to funding operations without the next round.
The record here belongs to Greg Mesch, founder of CityFibre (London, United Kingdom).
| | | |---|---| | Founder | Greg Mesch | | Company | CityFibre (London, United Kingdom) | | Total raised | $3.1B | | Latest round | Growth — $3.1B | | Round date | July 2025 | | Named participants on record | Infrastructure at Goldman Sachs Alternatives, Antin Infrastructure Partners, Mubadala Investment Company, Interogo Holding |
Lifetime capital equals this round. Anything earlier was small, undisclosed or non-dilutive.
The round size sets the next evidence bar. Investors size the following round against what this one was expected to buy. Write that expectation down before you sign.
Named participants signal the buyer pool. Infrastructure at Goldman Sachs Alternatives, Antin Infrastructure Partners, Mubadala Investment Company, Interogo Holding are on record here. Funds with that profile are the realistic audience for a comparable raise.
Timing is data. The round closed in July 2025. Fundraises take longer than founders plan; count backwards from the date you need cash, not from the date you want a term sheet.
1. Write the two or three pieces of evidence your next round must show. 2. Cost out the months and headcount required to produce that evidence, then add a third for slippage. 3. Build the investor list from funds that have written cheques of this size at this stage, not from brand preference. 4. Ask each lead what they expect to see at the next round, and hold them to it in writing.
The letter on the round matters far less than whether the money buys the evidence the next buyer needs.
