Software-as-a-service provider Model Metrics announced today that it took $2.5 million in first-round funding from undisclosed investors. The money will go toward development of iPhone apps and software tailored specifically for Salesforce.com.

The Chicago-based company supplies others with the mobile and computer software they need to eliminate pain-points in everyday business. For example, its Expense2GO product lets employees manage their company expenses remotely from their iPhones. Any changes made on the handset are automatically synced with expense histories stored with Salesforce.

Founded in 2003, the firm is now 60-employees strong and has offices in five cities across the midwest.
