The deal caught our eye because StarVest was also an early investor in NetSuite, owning 5% of the company according to the S-1 filed ahead of NetSuite’s IPO in 2007. (StarVest’s other SaaS exit came when Dell paid $155m in cash for portfolio company MessageOne, an on-demand email archiving company run by Michael Dell’s brother.)

StarVest’s interest in NetSuite dates back to May 2000, when it led a Series C investment in the SaaS applications suite vendor together with Oracle head honcho Larry Ellison. (Ellison, of course, is the co-founder and majority owner of NetSuite.) Iron Solutions and NetSuite teamed up in October 2007 to provide industry-specific applications for agricultural equipment dealerships, and the on-demand player often uses that example to illustrate how its software can be tailored to a specific industry.

Does StarVest’s simplification of the capital structure at Iron Solutions make a sale more likely, perhaps making the firm a broker in a deal between a pair of portfolio companies? (We would note that Oak Investment Partners recently played matchmaker in an inter-portfolio marriage of two SaaS companies.)

Speculation about a possible purchase of Iron Solutions by NetSuite may be a bit of a stretch. However, it’s worth noting that NetSuite’s only acquisition so far has been a vertical deal: the $31m purchase of OpenAir, which helped boost NetSuite’s services industry expertise.

Perhaps NetSuite could broaden the focus of Iron Solutions’ online marketplace, appraisal and valuation services to a much wider market. The applications vendor has already begun to offer applications tailored for light manufacturing and has voiced a desire to add in heavy manufacturing in the future. If it’s serious about those moves, NetSuite may well find that Iron Solutions’ equipment marketplace and other know-how come in handy. The two sides, and their backers, certainly know each other well enough.
