Astria Therapeutics has $700M on record. The latest round is a $110M Growth (January 2026). 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 Jill Milne, founder of Astria Therapeutics (Boston, USA).
| | | |---|---| | Founder | Jill Milne | | Company | Astria Therapeutics (Boston, USA) | | Total raised | $700M | | Latest round | Growth — $110M | | Round date | January 2026 | | Named participants on record | BioCryst, HHS, Perceptive Advisors |
This round is 16% of everything raised to date, so earlier rounds still shape the cap table.
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. BioCryst, HHS, Perceptive Advisors are on record here. Funds with that profile are the realistic audience for a comparable raise.
Timing is data. The round closed in January 2026. 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.
