From financing rounds and every investor named in them, Form ADV and Form D filings, the firm's funds and team, and disclosed LP commitments in the venture capital graph. A round's amount is the size of the round, not money that moved between two investors.
Some relationships on this record are counted rather than named here. They open with the full profile.

›How strength and recency are read
Co-investors are read from the rounds: three or more shared rounds is a strong observed relationship, two a repeat co-investor, one a single round. Funds and people are structural. Nothing is scored that a reader cannot check.
Darker lines were active in the last 24 months or are current; lighter lines are older or undated.
How am I connected?
Name your firm, a company or a person, and DFX finds the published routes to Abingworth LLP: a shared portfolio company or board, a prior employer, a co-investor, a shared LP or service provider. Every step is a filed or published record with its source; none is a guess about who knows whom.

What these amounts mean“This investor” is the amount disclosed for this investor alone; it is unknown unless a source said it. The round size is the whole round.Acquired, Public, Exited and Active are what the firm’s own portfolio card says, read on the date shown when you hover the chip; they are not deal dates. A company with no chip is one whose card states no outcome: DFX does not assume it is active.| Company | Round | Role | Partner | Round size | This investor | Date | Source |

Team
11 current, 2 departed
Decision makers
Ranked by the role the firm or its filing states, a route on file and deals led. Every reason is read from the record, never inferred. Routes are published by the person or the firm (their bio, the team page or a filing) and are revealed on a plan; data bought from a provider is never shown, and a route printed at a firm the person has since left is held back.
Investment team
How the team is orderedPartners who lead rounds first (rounds led, then deals attributed, then seniority), then the rest of the investment team, then investor relations, finance and operations. A person named by two sources under two spellings is shown once.- Owner · 3 deals attributed
- Owner · 2 deals attributed
Contacts

Funds and LPs
1 vehicle, 0 LPs disclosed
Funds and vehicles
What these amounts meanGAV is the gross asset value the adviser reported on Form ADV for the vehicle, never the fund’s committed size and never dry powder. Form D sold is the amount sold as of the latest filing, never a final close.| Vehicle | Type | Vintage | Lifecycle | Reported GAV | Owners | Form D sold | Latest Form D |

Limited partners
Known LPs and allocators
What these amounts and dates areEach commitment is counted once across the pension tape and the allocator graph. A commitment date prints only when the source printed one; otherwise the row carries the report date. A foundation’s 990-PF line is a holding at fair value, never a commitment. Rows without a fund on the venture graph are commitments to this manager.Relationships across DFX
