A build team agencies count on, working exclusively behind the scenes for them.
Every agency eventually gets a request outside its core offer, usually a website. That moment is either a growth opportunity or a liability, depending on who's behind the build.
Opasite Web Design exists to make it the former. Based in Quincy, MA, four-plus years and 50+ recommendations from local business owners back a track record of hitting deadlines and delivering results, now built specifically around agency partnerships.
We give marketing agencies, SEO specialists, and digital consultants a development partner they can hand a project to and trust it comes back right, across WordPress, Shopify, Webflow, and other major platforms. Landing pages, redesigns, ongoing maintenance: it all gets delivered under your brand, at the standard your clients expect.
Long-term partnerships are the goal. If consistent web work is part of your pipeline, let's connect.
From building websites for local businesses to building the web team behind agencies.
It started in 2013, when Sam Sternweiler launched his first business and found an unexpected passion: helping other business owners navigate the parts of running a company that weren't their expertise. That path led into web design, where years of hands-on client work revealed a pattern worth paying attention to.
By 2020, that pattern was showing up somewhere new: on the agency side. Marketing agencies, SEO consultants, and growth marketers were closing website deals confidently, then quietly scrambling to deliver them. The strategy and the sale were never the problem. The build was.
Today, Sam and a team of seasoned designers, developers, and SEO experts have turned that experience into a dedicated white-label practice for agencies who need a build partner they can trust every time.
