Reviews for OSMOSVerified

Aaron Aryeh at Conin

OSMOS built our entire website, The design, UI/UX, CMS, and all the functionality behind it. The team was incredibly communicative throughout and really understood not just what I wanted, but what my clients would need from the experience. That level of attention made a huge difference. Since launching, the site has helped me land new partnerships and grow the business in ways I didn't expect.

Wenian Guo at Toughtalk

OSMOS handled our app development from start to finish and stuck with us well beyond launch. They managed our app store optimization, ran our organic social strategy, and delivered the design work that tied everything together. Having one team from build to growth made a real difference in how quickly we were able to gain traction.

Caroline Sebastian at Sebastian Media

OSMOS came in as a strategic partner and helped me grow Sebastian Media through consultancy and business development support. They helped me refine my positioning and played a direct role in acquiring new clients. Having their guidance and expertise behind me gave me the push I needed to take my company to the next level.

Mordy Dachs, CEO at Jumpseat

OSMOS helped me build Jumpseat from the ground up. They developed our branding, defined our brand pillars, and handled the full web app design and development. Having that foundation in place early on gave me the confidence and credibility to go out and grow the business.

Samuel Vulakh, CTO at Appstackx

We partner with OSMOS on the branding and design side of our client projects. As a dev agency, we handle the build, Eli and his team handle the creative. They've delivered brand identities, UI/UX, and creative strategy across multiple engagements for us.

Chanoch Rabinowitz, CEO at Crawler

OSMOS helped us build everything from scratch — our business model, our brand, our app, and our go-to-market strategy. As a nightlife mobile app, we needed a partner who could think like a co-founder, not just a vendor, and that's exactly what we got. They developed our brand identity, then moved into full mobile app development across iOS and Android, including building a custom AI model that became a real differentiator for our product. The creative work was so dialed in that we barely needed design revisions, which saved us serious time and money. Once the product was live, OSMOS shifted gears into marketing and helped us prepare for our Series A — which we successfully closed. They were always accessible, whether in person or on a call, and responded fast no matter what we needed. Working with OSMOS genuinely felt like having another founder on the team who happened to bring an entire agency behind them.

Matan Magril, CEO at Jetpack

OSMOS has been our go-to partner for development and marketing across both our own business and our client projects. As a consulting firm that helps startups raise capital, we needed a team that could take a business strategy and execute it end-to-end — branding, web and mobile development, and performance marketing. That's exactly what OSMOS has done. They've built apps, websites, and platforms that tens of thousands of consumers and businesses use daily, and the quality has been consistently strong with minimal bugs thanks to their thorough QA process. On the marketing side, their campaigns have driven meaningful lifts in downloads and purchases, and their branding work always speaks directly to the audience it's meant for. What sets them apart is that they don't just take a brief and run — they bring real research and subject matter expertise to every project. Over the course of our partnership, we've invested close to $1 million across multiple engagements, and they've exceeded expectations on every one. They've become an extension of how we serve our clients.

Moshe Weitzner, Buisness Development at XSHACK

OSMOS came in and built everything from the ground up - our brand, our app, our website, and our entire digital marketing engine. For a cannabis company trying to establish credibility and stand out in an oversaturated market, having a team that understood both the creative and technical side was critical. They developed a brand identity that actually resonated with our audience, built a mobile app that our customers love using, and launched an award-winning landing page that immediately boosted our visibility. Beyond the build, they've stayed on as a true partner- managing our SEO, running social campaigns, and continuously refining our strategy. Communication has been seamless, deadlines have been met, and the team has consistently shown up with the same energy they brought on day one. OSMOS didn't just help us launch — they helped us compete.

Arsh Tawlar, CTO at TRNDZY

OSMOS partnered with us on UX strategy, journey mapping, and web development — handling the full design-to-build pipeline so we could stay focused on what we do best. Communication was streamlined from the start; nothing got lost in translation, and turnaround was fast. They quickly embedded themselves into our workflow and essentially became part of our team, understanding our clients' goals as if they were their own. Beyond launch, OSMOS stuck around to support post-launch efforts including marketing and app store optimization, which is rare to find in a design and dev partner. For a startup like ours, having that kind of reliability and range in one team made a real difference in how we were able to scale and deliver for our clients.
