      Diffco built a complex, production-grade AI agentic system and backend for our client's fintech platform owning architecture, AI/ML components, and AI agents in a security- and compliance-sensitive environment. They delivered on time and within budget, communicated proactively, and operated like part of our own team, taking ownership and suggesting better solutions throughout. Deep AI/ML and senior backend expertise. We'd happily work with them again.

They handled everything: UI/UX design, backend architecture, API integration, and deployment. After the launch, they continued to support us with maintenance and performance optimization.

While there is some room for improvement in developer vetting and quality assurance, their overall service was excellent. For companies looking to scale their development teams efficiently, Simform is a reliable partner. Their structured approach, responsiveness, and commitment to client satisfaction make them a great choice. We would recommend them without hesitation.

      Branding Review from Anonymous

      I'm a department director at a consumer technology protection company, overseeing our website and Amazon channels. We engaged Netalico Commerce to implement our rebrand and completely overhaul our website's frontend. Netalico successfully implemented our new design and developed custom features for our e-commerce platform. They've become our web development partners, continuously adding integrations and improvements. Using Magento, PHP, and SQL, they built custom features including product registration for lifetime warranties and insurance claim management directly through our site. In 2021, they executed a complex multi-company project integrating our insurance plan data into POS systems across North America, enabling virtual insurance sales at retail locations. I work directly with Mark (CTO & Founder), Emily (E-Commerce Solutions Specialist), Bianca (Project Manager), and Lisa (Chief Design Officer). We've been working together since May 2020 on a monthly retainer basis. Netalico has executed all projects exceptionally well, consistently meeting deadlines and launch dates with accurate quotes. We communicate through weekly meetings, Slack, chat, and email. What impresses me most is their outstanding team structure. They have talented, highly skilled members organized efficiently for optimal project delivery. They make the client experience seamless.

      Beauty Marketing Review from Anonymous

      I manage a beauty brand, and we engaged Netalico Commerce to handle our web development and email marketing needs. After an initial strategy call to understand our priorities, Netalico Commerce developed a comprehensive plan to address our requirements. They now maintain our Shopify e-commerce platform and implement ongoing updates. The site features shopping capabilities, a blog, and class registration. Katherine, our Director of Operations and primary contact, leads the engagement with support from her design team. The results have been impressive - our conversion rate has increased, and they've outperformed previous developers in efficiency, response time, and organization. They consistently deliver on schedule and within budget, using Trello, email, and Zoom for seamless communication. Their standout quality is their ability to efficiently manage multiple projects simultaneously while maintaining high standards across all deliverables. Katherine excels at prioritizing our needs and finding effective solutions. Their onboarding process for new clients is excellent - I highly recommend utilizing Trello for optimal collaboration.

      Website Redesign Review from Anonymous

      I hired Netalico to redesign and develop our e-commerce site for our historic lighting and home decor business. We needed to modernize our outdated WordPress platform and handle our highly customizable products. Netalico rebuilt our site from scratch, creating a beautiful platform that seamlessly manages our complex product customization and integrates with external apps. They developed an efficient product page system and added content capabilities we previously lacked. We worked primarily with Bianca (project manager), a developer, and Lisa (designer). The site launched successfully and maintains our steady revenue stream while delivering the exact customer experience we envisioned. What distinguishes Netalico is their willingness to understand our unique needs rather than forcing us into a template. They listened carefully and tailored their approach accordingly.

      Web Development Review from AJ Canty

      We’ve been working with Vention for quite some time and consider them an extension of our team, rather than an offshore vendor. We needed solid mobile developers to work with our in-house engineers to build our Primer SDKs on both mobile platforms. This was not a trivial thing as it required a lot of cross-functional communication, but the Vention team was up to the challenge. They quickly adopted the best practices we follow at Primer and proved to be effective and proactive.
