Investment in the first quarter of 2007 was down 27.5% to $100.4m, resulting in an overall decline in open source funding in the first half of the year of 6.4% to $198.85m, compared to $212.30m in 2006.

Of a total of 15 investment deals in the second quarter 12 had disclosed investment value, giving an average deal size of $8.20m, compared to $7.36m from 10 deals with disclosed value in the second quarter of last year.

For the first half of the year a total of 27 deals were done, 23 of which had a value disclosed, giving an average deal size of $8.65m, while there were 24 disclosed deals done in the first half of 2006, with an average deal size of $8.85m.

The biggest deal of the quarter was done by real-time Linux specialist Concurrent via its $14m private placement, while open source ESB vendor MuleSource raised $12.5m in May. JasperSoft is meanwhile on its way to closing a $12.27m Series D round, but had only secured $11.0m by the end of quarter.

UPDATE
Matt Asay suggests I keep a note of the running total. I have two figures - one I am confident about: $2.05bn since 2000 and one that probably has some historical gaps:
$2.18bn since 1997.
