Top Optimizely Partners And Development Companies In 2026

Compare the top Optimizely partners in 2026: 12 verified Optimizely solution partners and development companies, with partner tier, certifications and focus.
Optimizely, the platform formerly known as Episerver, sits at the enterprise end of the CMS market, and the Optimizely partner you hire to implement it matters as much as the licence itself.
Optimizely runs a structured solution partner programme with published tiers, and its top tier is not handed out lightly. To reach Platinum, a partner has to hold at least ten Optimizely developer certifications, keep twenty sales enabled staff, earn product specialisations and hit an annual new sales revenue threshold. A small group above that holds Premier Platinum status. Tiers are also assigned per country, so the same agency can sit at Platinum in one market and Silver in another.
The twelve Optimizely partners below are all verified solution partners, checked against Optimizely’s own partner listings and their published work in October 2026. Each entry shows the partner’s current tier. They range from consultancies that build on nothing but Optimizely to global agencies where it is one platform among many, and that distinction is called out for each one. Several began as Episerver agencies and carried that platform history through the rebrand, which is why long partnership tenures show up so often below.

Best Optimizely Partners And Development Companies In 2026
1. Netcel — The UK’s First Optimizely Only Platinum Partner
Netcel has held Platinum status since 2007 and works with Optimizely exclusively, which makes it unusual among top tier partners. Its partner listing shows 42 global certifications and three product specialisations across CMS, Commerce Connect and Configured Commerce, and the team claims the largest group of Optimizely Most Valuable Professionals of any UK partner.
The award record is unusually dense for a specialist: UK Solution Partner of the Year in 2024, Customer Choice awards in 2022 and 2023, DXP Partner of the Year in 2021, and AI Innovator of the Year in 2025 for its work with Opal, Optimizely’s AI layer. Because its entire customer base runs on Optimizely, there is no competing platform in the room when it recommends an approach.
Services and expertise: Optimizely CMS builds, Commerce Connect and Configured Commerce, experimentation, Opal AI adoption, optimisation and support
Tech stack: Optimizely CMS, Optimizely Commerce, Web Experimentation, Opal
Industries: Construction and property, plus the largest base of Optimizely clients of any UK partner
2. Verndale — Premier Platinum And Twice North American Partner Of The Year
Verndale is one of a handful of Premier Platinum partners in North America and was named Optimizely’s North American Solution Partner of the Year in both 2021 and 2023. Headquartered in Boston, it holds specialisations in CMS, Configured Commerce and Customized Commerce, and reports seven agency MVP awards.
Its commerce depth predates Optimizely’s B2B product: Verndale was a Platinum partner to Insite Software before Optimizely acquired it in 2019 and renamed it Configured Commerce. Named clients include Johnson Financial Group, Manhattan Associates, IEWC and Quinnipiac University, a mix that leans toward B2B distributors and regulated finance.
Services and expertise: Strategy, experience design, CMS implementation, B2B and B2C commerce, Opal and agentic AI, content migrations, personalisation
Industries: Manufacturing and distribution, financial services, higher education, technology
3. 26 DX — An 18 Year Platinum Partnership Inside The MSQ Group
26 DX, part of the MSQ agency group, is one of Optimizely’s longest standing Platinum partners, with an 18 year relationship behind it. It took Optimizely’s UK Solution Partner of the Year in 2022, Digital Experience Partner of the Year in 2023 and the UK Customer Choice award in 2024, the last of those voted for by clients rather than by Optimizely.
The wider group runs to around 400 people, which gives it the creative, data and performance teams to run a full Optimizely One programme rather than a build alone. It names Opal AI as a specialism and holds ISO 27001 and Cyber Essentials Plus, which matters for regulated procurement in the UK.
Services and expertise: Digital product strategy, experience design, Optimizely implementation, Opal AI enablement, performance marketing, support
Tech stack: Optimizely CMS, the wider Optimizely One suite, Opal
Industries: Enterprise organisations across the UK, DACH and North America
4. Valtech — All Four Product Specialisations And Twelve OMVPs
Valtech has worked with Optimizely for more than 23 years and holds Premier Platinum status. It is one of very few partners to hold all four Optimizely product specialisations, and it reports more than 75 global certifications, over 350 engagements and twelve Optimizely MVPs.
This is the option for an organisation running Optimizely across several countries and products at once. The trade off is that Valtech is a large global consultancy with many platform practices, so it suits buyers with the budget and governance to work at that scale rather than teams wanting a small dedicated crew.
Services and expertise: Enterprise transformation, DXP implementation, commerce, experimentation, AI powered integrations, marketing performance
Industries: Global enterprises running Optimizely across several markets
5. Perficient — Premier Platinum With A Banking Specialism
Perficient is a Premier Platinum partner whose Optimizely practice is built around complex enterprise integration. It says it works with 18 of the 20 largest US commercial banks, and its stated strengths are custom middleware, headless architectures and integrating Optimizely with ERP and PIM systems.
That integration focus also shows up in B2B, where Perficient handles customer specific pricing, multi warehouse inventory and complicated purchasing flows for manufacturers and distributors. Its coverage spans CMS and SaaS CMS, Configured Commerce, experimentation and the Optimizely Data Platform.
Services and expertise: Optimizely One implementation, headless and composable architecture, ERP and PIM integration, data activation, experimentation
Tech stack: Optimizely CMS and SaaS CMS, Configured Commerce, Optimizely Data Platform
Industries: Banking and financial services, manufacturing, distribution
6. Rightpoint — More Than 75 Certified Developers And A Seat On The Advisory Board
Rightpoint has partnered with Optimizely for close to a decade and holds Platinum status with 48 global certifications and three product specialisations. It reports more than 75 Optimizely certified developers on staff and sits on Optimizely’s Partner Advisory Board, which gives it an early view of the product roadmap.
Its differentiator is that the build is led by customer experience strategy and design rather than engineering alone, with marketing and analytics teams attached to get value out of the platform after launch. It has been recognised as a specialist in both content management and commerce, and has won Partner of the Year more than once.
Services and expertise: CX strategy, experience design, CMS and commerce implementation, personalisation, marketing and analytics
Tech stack: Optimizely CMS, Optimizely Commerce, Optimizely One
Industries: Large enterprise brands across B2B and B2C
7. UNRVLD — European DXP Partner Of The Year, Built For Ecommerce Growth
UNRVLD holds Platinum status, which it gained through acquiring Optimizely partner Made to Engage, and specialises in CMS, Commerce Connect and Web Experimentation. It was named European DXP Partner of the Year in 2022, UK and Ireland Solution Partner of the Year, and Optimizer of the Year for its work with New Era Cap.
Roughly half its clients run on Optimizely, and its published roster is strong on consumer and commercial brands: New Era Cap, SMEG, Permanent TSB, Lloyd’s Register, LIV Golf, NTT and Manpower. Two OMVPs lead the technical team, and its pitch centres on ecommerce metrics rather than platform features.
Services and expertise: Digital experience strategy, Optimizely CMS and commerce builds, experimentation, ecommerce growth, creative and performance marketing
Tech stack: Optimizely CMS, Commerce Connect, Web Experimentation
Industries: Retail, manufacturing and distribution, commercial services, technology, financial services
8. Niteco — The Largest Bench Of Certified Optimizely Developers
Niteco is a Gold solution partner rather than a Platinum one, but it describes itself as Optimizely’s largest global partner, and its numbers support that: more than 150 certified developers, over 2,000 Optimizely projects delivered, 73 Opal certified experts and four product specialisations. It also has four Platinum level OMVPs on staff.
The tier difference reflects how Optimizely weighs sales revenue alongside technical capability, so it is a useful reminder that tier alone does not measure delivery capacity. With offices across Europe, North America and Asia Pacific, Niteco suits organisations that need a large team or around the clock coverage, and it has won Commerce Partner of the Year.
Services and expertise: Strategy, UX and UI design, Optimizely development, ecommerce, Opal AI, experimentation, SEO and analytics, ongoing support
Industries: Legal, financial services, real estate, technology, healthcare, retail
9. ACTUM Digital — Platinum Partner For Multi Country European Rollouts
ACTUM Digital is one of Europe’s larger independent digital agencies and an Optimizely Platinum solution partner, with more than 400 people across Prague, Düsseldorf, Zürich and the Netherlands. It has delivered rollouts spanning more than 40 sites and languages on Optimizely.
What sets it apart is the integration practice around the platform. ACTUM runs dedicated AI, CRM, PIM and ERP teams, so Optimizely can be connected to Salesforce, Microsoft, SAP and Google from the start of a project instead of in a second phase.
Services and expertise: Consulting, design, Optimizely build, composable architecture, CRM, PIM and ERP integration, long term optimisation
Tech stack: Optimizely, Salesforce, Microsoft, SAP, Google
10. The C2 Group — The Agency That Builds Optimizely’s Own Website
The C2 Group is a family owned agency in Grand Rapids, Michigan, and one of very few Platinum partners with fewer than 200 employees. Its most checkable credential is its client: C2 is the chosen development partner for Optimizely’s own marketing team and supports optimizely.com, including a design system it built for the company.
It holds specialisations in Content Cloud and Commerce Cloud, has more than fifteen years of Optimizely partnership, and sits on the Partner Advisory Board. For a mid market buyer, it offers top tier credentials without the overhead of a global consultancy.
Services and expertise: Strategy, design systems, Optimizely CMS and commerce development, experimentation, support
Tech stack: Optimizely CMS, Optimizely Commerce, Web Experimentation, Optimizely Data Platform
Industries: B2B and B2C brands
11. Velir — Promoted To Platinum In 2025 With An Experimentation Specialism
Velir was certified as an Optimizely Platinum solution partner in September 2025, having added new product specialisations including experimentation and completed Optimizely’s advanced training to get there. It describes itself as a data driven experience agency, and its Optimizely work reflects that, with testing and personalisation treated as part of the build rather than a later add on.
As a recent Platinum arrival, Velir has fewer partner awards than older names on this list, so ask for reference projects that match your scale. The upside is a team that has just been through Optimizely’s full assessment process.
Services and expertise: Digital strategy, experience design, Optimizely implementation, experimentation, personalisation, analytics
Tech stack: Optimizely CMS, Web Experimentation, Optimizely One
Industries: Mid size and enterprise organisations; ask for references in your sector
12. Mando Group — A B Corp Consultancy Built Entirely Around Optimizely
Mando Group is a Liverpool consultancy of around 40 people and an Optimizely Platinum partner. It describes itself as the only B Corp consultancy in the UK built entirely around Optimizely, and it has been delivering digital work for more than 25 years.
Its emphasis is on what happens after launch: 24/7 support, maintenance and continuous product optimisation, with client relationships that typically run for years. Coverage spans the Optimizely CMS, Content Marketing Platform, personalisation and commerce.
Services and expertise: Optimizely implementation, support and maintenance, optimisation, content marketing platform, personalisation, commerce
Industries: Clients across the UK and internationally, typically on multi year engagements
How To Choose An Optimizely Partner
Is The Tier Current, And In Your Country?
Optimizely assigns tiers per country, so an agency can be Platinum in the UK and Silver in the United States. Check the tier listed for the office that will actually deliver your project, and confirm it on Optimizely’s partner directory rather than on the agency’s own website.
Does The Tier Tell You What You Need To Know?
Tier combines certifications with sales enabled staff and annual new licence revenue. That is why a partner with a very large certified team, such as Niteco, can sit at Gold while smaller firms hold Platinum. If delivery capacity is your main concern, ask for the number of certified developers who would work on your account, not the badge.
Which Optimizely Products Are You Actually Buying?
Optimizely now spans CMS and SaaS CMS, Configured Commerce, Customized Commerce, Web and Feature Experimentation, the Content Marketing Platform, the Data Platform and Opal AI. Product specialisations are published per partner. Match them to your roadmap, especially for B2B commerce, which is a distinct skill set from content builds.
Specialist Or Multi Platform Consultancy?
Netcel and Mando Group build on Optimizely alone. Valtech, Perficient and Rightpoint run many platform practices. A specialist has deeper bench strength on the platform you have already chosen, while a multi platform consultancy can be more useful if you are still deciding, or plan to connect Optimizely to a wide enterprise stack.
Who Owns The Platform After Launch?
Some partners lead with builds and others with long term support and optimisation. If your internal team is small, prioritise a partner with published support arrangements and a history of multi year client relationships, and agree upgrade responsibilities before signing.
Conclusion
Optimizely’s partner programme makes the shortlist easier to verify than most enterprise CMS categories, because tiers, certifications and specialisations are published by Optimizely rather than self declared. The real decision is fit: a specialist or a multi platform consultancy, a build partner or a long term operator, and a team with specialisations in the Optimizely products you will actually run. Settle those questions first, then use tier, certification depth and sector experience to narrow the field.
