Wearable computing hardware company Jawbone has acquired Portland-based digital design firm Visere, a startup that already played an important role in designing Jawbone’s UP wristband fitness app.

“Many thanks to those who got to this point, and just as many to those who we’ll be working with in the future,” Visere’s home page now reads. “We’re thrilled with the opportunities and challenges this new development brings, and excited to work with such an incredible family of products.”

GigaOM first reported on the deal, which also included Jawbone’s acquisition of MassiveHealth. About 25 people between the two companies will continue on with Jawbone, a San Francisco-based company that first made headsets for mobile phones and recently expanded to wearable computing devices.

“We share Jawbone’s passion for creating delightful experiences that people want to engage with every day,” Visere founder Roberto Tagliabue said in a press release. “And together, we’ll be able to add a new level of digital experience expertise to Jawbone’s category-defining products.”

Interesting to point out that Portland, home to Nike+, Nike Fuel and the Nike+ Accelerator, is kind of becoming a hub for wearable computing devices, as Silicon Forest notes.
