Membership Opportunities

Programs, Events, and Groups

One of the main reasons people join 1si is the chance to meet other professionals and connect with other businesses.  Our monthly 5 O’clock Networks, each hosted by a different company or organization, give you the chance to meet and mingle with other business people and make new connections.  Our Networking on the Green Golf Scrambles provide a more relaxed way to meet other members.  Events like our Annual Meeting and Once Awards provide another forum to engage with other members over lunch or dinner.  Volunteering on a committee lets you work side by side with other professionals and develop deeper relationships.  And all of the groups and events you’ll find throughout this site offer new opportunities to make the connections you’re looking for to help you and your organization thrive.

Every month, the 1si calendar is filled with events for members to attend, from monthly to quarterly and annual gatherings.  In addition to the advantages of attending, you or your company can also be a sponsor for most of our events, and increase your exposure and name recognition among members and potential members.

The ONE Fund & Other Funding

The ONE Fund and the Small Business Navigator program represent a strategic partnership between One Southern Indiana and the Indiana Small Business Development Center.  The program offers business owners an all-inclusive resource for accessing the capital required for start-up and growth initiatives, as well as the education and advising resources necessary to build a strong, strategic, and sustainable business.
