About this entry

Parts of this entry are out of date. It is published anyway, because an incomplete record that invites correction is more useful than no record at all.

Person

Who this is

Co-founder and general partner of Technology Venture Investors, later founder of August Capital, and for many years the only outside venture investor on Microsoft's board.

The class project Jonathan Hare did for him — a study of TGV Software, a cross-platform networking company on whose board he sat — is the hinge of the whole early record. It put Hare into Microsoft, and it is why he bought every book on networking he could find.

S-100 dates the mentorship's sharpest exchange: a pivotal 1992 lunch at which Marquardt asked Hare who the big winner of his GSB class would be — noting that Scott McNealy had been the undisputed big winner of the classes of '79–'80 — and the 2003 D1 corridor where Marquardt, spotting Hare with McNealy and Meg Whitman, completed the three-billionaire circle himself.

The record

Where this intersects the work

Each entry below carries its own provenance — the source, and how it was processed. That is the condition on which this graph can be extended by anyone without degrading.

The trail exists so that people who were there can reconstruct their own memories, recognize what they helped incubate, and add to or correct the record — or forward the few pages that belong to someone they know.

1990–92

What the study produced

TGV Software built TCP/IP networking bridging Macintosh, PC, Unix and VMS systems, and Marquardt sat on its board through Technology Venture Investors. Hare already knew something about networking, having taken a course on IBM's Systems Network Architecture — what he had used on IBM machines in the seventies and eighties. The study led to a summer placement in Building 1 at Microsoft, and to a standing relationship.
