Additional is a design studio built on collaboration — founded by design director Jeff McWeeney after nearly two decades helping global brands imagine, design, and market experiences that added millions in value, and delivered significant impact to the communities they served.
We partner with early-stage companies, small businesses, and enterprise platforms to define a modern vision, architect the system, shape the experience, and rally cross-functional teams behind the stories that must be told.
Partner with organizations to uncover what truly matters to the people they serve — and bring that value into focus through strategy, research, and design systems that reflect how people think, feel, and connect.
Build teams and processes that cut through complexity — turning insight into clarity, and clarity into products people trust and understand.
Work with leadership to define meaningful change — grounded in culture, tested in the real world, and scaled when it’s time.
Guide bold ideas from spark to launch — faster, clearer, and in tune with how people live and work.
Support internal teams with flexible design leadership that balances creativity, business needs, and cultural understanding.
JPMorganChase, AstraZeneca, TD Bank, Mondeléz International, Salesforce, Target, Walmart — plus startups and nonprofits that believe design can move people, not just metrics.
If the status quo isn’t challenged, how can there be change?
What if all businesses prioritized the planet over profit?
What’s preventing inclusion from operating as the norm?
Can ethics make culture more resilient, and future proof?
What if joy was a feature, and became a leading KPI?
Is beauty missing, or is it compromised by technology?
When has a purchase made you feel something genuine?
Why isn’t imagination at the center of every business model?
The studio launched in 2014 with Jeff McWeeney as a design collaborator supporting teams at Accenture Federal, Salesforce, U.S. Postal Service, Department of Defense, and AT&T Digital Life.
Relationships quickly grew to include collaborations with Sam Adam's, Gannett, Nuvei, Truist, J.P. Morgan, AstraZeneca, Novartis, and Takeda Pharmaceuticals supporting digital strategy, product design, and connected systems.
Jeff's work continues in collaboration with startups and early-stage companies to design, and deliver human-centered experiences built on advanced technology.
I’m a designer first-and-foremost, passionate about modern, functional design, with a strong bias toward storytelling.
Over the last 20 years, I’ve focused on creating experiences for emerging platforms, advanced technology, and connected systems.
Design isn’t just about how something looks — it’s a way of thinking, and working that move things forward. For me, that means creating experiences that are thoughtful, human, and built to make the digital world feel a little more natural.
I’ve created pioneering experiences and digital firsts during Yahoo!'s global dominance, and recently, alongside executive teams at JPMorganChase, Adobe, Salesforce, Accenture Federal, the U.S. Department of Defense, AT&T, AstraZeneca, and Intel.
And, in 2021, I founded ZeroNow, and designed the Path to Safer Schools — a set of national standards born from Zero's design lab focused on creating what school safety needs next.
I also mentor students through the Young Entrepreneurs Academy, and support inspiring entrepreneurs through Sam Adam's Brewing the American Dream program.
It's been a privilege to guide, contribute, and collaborate with some of the world's most pioneering organizations, and their leadership teams.
Product archive is in the works to showcase a selection of experiences for Salesforce, McDonald's, AT&T, and a few others.
