›How strength and recency are read

Venture relationships are not scored. Each line names its claim: a round led or joined, a board seat or a filing that names the firm, a listing on a portfolio page (dated by when DFX saw it, never by when the investment was made), a disclosed LP commitment, or a co-investor pair counted from observed participations. Observed means a named source says so; Derived means DFX counted it from observed rows; Inferred means a match that may be wrong.

Darker lines were active in the last 24 months or are current; lighter lines are older or undated.

Documented career timeline

0 entries

No SEC officer change or named transaction is linked to this record yet. A filing is linked only when its employer matches one on this record, never on a name alone.

Influence, as documented: four separate measures

Each measure is a count of rows you can open, with its sources. They are never added together and never ranked. A relationship or a role is evidence of a connection, not of wrongdoing.

Documented decision authority

Officer and director appointments in the registrant's own 8-K, board seats, and executive or managing roles a filing or the firm's record names.

Expressable, Inc.: Board seat (Director) venture capital record

What it cannot see: Investment committee seats and votes in pension minutes are rarely documented, so they are not counted.

Roles on this record

Transaction involvement

Deals whose announcement names this person in a role.

None documented on this record yet.

What it cannot see: Bankers, lawyers and lender deal teams are rarely named in announcements, and capital per person is almost never attributable.

Transactions naming this person

Network position, documented lines only

2 institutions and 0 people on documented lines. A count, not a rank.

Expressable, Inc.: Director venture capital record
HarbourVest: Principal venture capital record

What it cannot see: Duplicate records split one person's lines across two or more profiles until they are merged.

Patterns DFX reads from the rows above. They are DFX's reading, not a filing's statement, and imply nothing about conduct.

None documented on this record yet.

What it cannot see: Needs at least two documented rows to read a pattern; one row is never a pattern.
