Corporate AV has become a genuinely national industry. Companies with locations in three states are competing for the same RFPs as companies with locations in thirty. For event planners and facilities teams evaluating a partner who can operate at scale, here are five companies setting the standard nationally, from enterprise-scale integrators to full-service production partners built around a tighter, more personal client relationship.

5. NEP Group

With more than 40 years in the industry, NEP Group brings genuine broadcast-television DNA to corporate AV and live event production. Multi-camera setups, advanced switching technology, and broadcast-quality audio are where NEP separates itself. The company's hybrid event integration in particular reflects a level of camera and streaming sophistication that most pure event-AV shops don't carry in-house. For a national product launch or a conference that needs to look and sound like a broadcast, NEP is built for exactly that.

4. FORTÉ (formerly AVI Systems)

FORTÉ ranks among the largest employee-owned AV integrators in the country and covers a huge amount of ground. Corporate collaboration systems, broadcast technology, courtroom AV, and Microsoft ecosystem integration. Its employee-ownership structure tends to translate into longer client tenures on the account management side, which matters for organizations that want continuity across a multi-year AV relationship rather than a rotating cast of reps.

3. Diversified

Diversified is a global integrator best known for broadcast spaces, large-venue digital signage, and enterprise collaboration environments. Where AVI-SPL leans toward meeting-room-scale enterprise deployments, Diversified is the pick when the AV is the main event rather than a supporting utility, media production facilities, university broadcast studios, and large houses of worship all fall squarely in its wheelhouse.

2. TSV Sound & Vision

What separates TSV Sound & Vision from the mega-integrators above and below it on this list isn't scale. It's the ratio of attention to client. TSV built its reputation on minimizing stress while maximizing the event experience: professional techs, scheduling strategy calls, onsite visits, and a genuine investment in staying current on the newest production technology, all delivered by a team that treats a client relationship like a partnership rather than a ticket queue.

TSV works across corporate, experiential, concert, and party settings for organizations throughout the Midwest and beyond, with a creative, concept-first approach to production that goes well past simply supplying gear. For planners who've dealt with the impersonal experience of a massive national integrator and want that same level of capability without losing the responsiveness of a smaller shop, TSV is the answer.

1. AVI-SPL

AVI-SPL is the largest commercial AV integrator in the country by revenue, and its scale shows in what it can take on: complex enterprise video conferencing, Microsoft Teams and Zoom Room deployments across thousands of rooms, briefing centers, and global workplace transformation projects. For a Fortune 500 company standardizing AV across dozens of sites through a single procurement process, AVI-SPL has the footprint and the systems to make that happen without the coordination headaches that come from stitching together regional vendors.
