I've worked in Battery621 for over 3 years and this place is the absolute best!! The owners and manger are super friendly. They love supporting the community and there are always fun events going on, including free breakfast at Waffle Wednesdays! It's a dog friendly office and overall a great community.

When you first explore the place, the mix of companies is a little hard to mentally organize. Outdoor and lifestyle brands next to a consulting firm, a construction company, fabrication, plus technology, creative, media, nonprofits, oh… a custom cabinetry shop, and of course, a pool builder. But everybody here is chasing something they actually care about. They’re passionate about what they’re making, selling, marketing. They are passionate about their customers, their industries. It’s a building full of makers, doers and entrepreneurs rolling up their sleeves, working for their passion and not just a paycheck (but hopefully a paycheck). You don’t find that everywhere, and man, it’s something when you do. The social side is awesome too. Bands on the rooftop, celebrity and pro athlete panels, ski movie screenings, adventure parties, coffee meetups, social hours and Waffle Wednesdays (if you don’t know Waffle Wednesdays, now you know). I didn’t come here to make friends, but you try coming here and see what happens. The production facilities are the cherry on top for me. For a company like mine that creates content for brands, having a professional grade sound stage and studio in the building is a force multiplier.

Battery is easily hands-down one of the best shared office spaces I’ve worked out of. The space itself is fantastic, but what really sets it apart is the energy and the team behind it. The operations team consistently goes above and beyond to build a genuine community, and the events they host are next-level. Case in point: they recently threw a “Woofle Wednesday” dog-friendly breakfast that completely made my week. Pulling off creative, high-energy events like that takes serious behind-the-scenes effort, and the folks that run this place makes it look effortless. I find myself bragging to friends all the time about coming into the office here. If you’re looking for a vibrant, welcoming, and well-run workspace, Battery is it. Couldn’t recommend them more!

Great workspace, amazing amenities, excellent customer service. The only draw back is parking but thats navigable. I will use this space exclusively from now on when I need it.
