First I was interested in the most recently active investors - for this I only included investors with at least 3 investments (MinLink =3) in the Biotech and Medicine sectors over the past year.  I then dropped pendants to only show the connections between these investors.  

1st Round SV Health-Tech Companies Recent Activity Investment Map (Pendants dropped, MinLink=3).  Large blue boxes indicate Health-Tech companies that were funded in March, 2007.  Small blue boxes indicate Health-Tech companies that were funded from 3/06-2/07.  Source: LinkSV.com 

Network Commentary:

• On average, these companies were on Round 3.1, raised $20.5M in latest round funding, and had 6.89 investors

• These companies had no investment relations in Health-Tech over the past year
• On average, these companies were on Round 2.0, raised $10.0M in latest round funding, and had 3.14 investors

• The most active investors were Alta Partners (9), Morgenthaler Ventures (6), and Asset Management Company (5)
• Alta Partners invested in 6 Health-Tech start-ups in March, 2007 (Aerovance, Coapt Systems, PneumRx, ChemoCentrix, DiscoveRx, and Intarcia Thera) 

Next I examined recent board interlocks of Health-tech companies.  For this, I clicked on the People Map for the aforementioned search criteria.  The goal of this map is to indicate recent board member activity in the SV Medicine & Biotech Sectors.

Network Commentary:

In summary, the purpose of this post was to identify the companies, investors, and board members in recently funded Biotech and Medical sector fundings.  While the majority of these funding were for later round companies, the recent key players were evident from the network analyses: People: Guy Nohra (Alta), Kathy LaPorte (New Leaf), John Walker (Novacea); VCs: Alta, NEA, and OrbiMed as central hubs; St. Paul & Morgenthaler as co-investors.  Of course, there are several other ways to examine recent activity such as: (1) only looking at the Biotech Sector or Medical sector; (2) Company filters for rounds of capital, Recent round $, total funding $, or start year; (3) Changing the dates of what defines recent activity (to, say, the past 6 months only); and (4) Using keywords to further identify specific company products.  Registered LinkSViewer users are encouraged to tinker with the maps using the above criteria. 

1st Round SV Internet Companies Recent Activity Relational Map.  Large blue boxes indicate Internet start-up (1st round) companies that were funded in March, 2007.  Small blue boxes indicate all Internet companies that were funded in March, 2006 or later.  The goal is to map recent activity in the SV Internet Sector.

Network Commentary:

• 14 Internet-Sector 1st Round SV companies were funded in March, 2007 (Industrious Kid, Wesabe, Outspark.com, Scribd, Xobni, kwiry, Fliptrack, Teracent, Popular Media, Oodle, Rock You, Kongregate, Flixster, & cFares) - Source: LinkSV.com
• David Sze (Greylock: Marquee, LinkedIn, & Digg) has the most board ties (3) for Internet companies that received funding over the past year
• Peter Sonsini (NEA: Compiere & Teracent) and Ravi Mhatre (Lightspeed: Flixster & Kosmix) both have 2 board ties on the map - one 1st round company funded in March, 2007 and one over the past year

Honing in on the investor relations from the above map, I dropped pendants and for the below Investment Map:

Network Commentary:

• 9 Internet-Sector 1st Round companies funded in March, 2007 have investment ties over the past year (Scribd, Xobni, Teracent, Popular Media, Oodle, Industrious Kid, Rock You, Kongregate, & cFares)

• Y Combinator (Scribd & Xobni) Steamboat Ventures (Popular Media & Industrious Kid) both have 2 Internet-sector investments in the past month

Practical Uses (Whys)

The above map and analysis can be used to see who has been active in the Internet Sector over the past month and year.  It is meant to save users time by illustrating funding activity in one map with one-click summary information (in the Information Window or to LinkSV Company Summaries or People Profiles).  This information can be used by companies seeking funding, VC firms or angels surveying the investment space, or anyone looking for latest trends.  Some potential specific questions:

• Who are the recently active investors?
• What companies are they co-investing in?
• How are these companies related to each other? 
• How are these companies related to my company?
• What are the capital-based ties for collaboration?

Of course, LinkSViewer 1.2 can generate similar activity maps for different sectors, datelines, keywords, rounds, capital $, etc.  It can also be used to find board member and/or management team relations in addition to investments.  Registered users are encouraged to play around with either of the above maps (e.g., filter, node or link alteration).  We plan on integrating this festure into our front page as a way to help registered users quickly discover recent funding activity and relationships (Thanks to Paul Sherer at PodTech for this suggestion).  Contact us if you have any suggestions or specific requests for activity maps.
