Our story
More Than Just a Development Company
2006 founded35+ certified specialists6 years average tenure
ZestIQ was founded in 2006 and did business as Zest Logic until 2026, building and supporting online stores for US and European brands on Magento, Shopify and BigCommerce. In March 2026 the company became ZestIQ. The team, the clients and the work carried over; the name changed to match what we build now: AI products for ecommerce alongside the store engineering we have always done.
We are a community of engineers who teach each other. With an average tenure of six years, and many specialists past a decade in the field, the knowledge stays in the team and ends up in your store. The same people stay with a store after it launches, so the reasons behind a decision are still in the room when it needs changing. The engineer who writes the code is the one you talk to, which keeps a question and its answer in the same conversation.

as their sole technical partner
They designed for where the product was going, not just what we asked for. Early on we described a single-company setup; they built the data model and permission layer so multi-tenancy wouldn’t require a rewrite later.

Partners on the Platforms We Build On
Adobe Silver Partner
Adobe's partner badge covers Adobe Commerce and Magento Open Source. The certifications behind it are held by the developers, architects and business practitioners who do the work, not by the company in the abstract.
Hyvä Partner
Hyvä is the frontend we move a Luma storefront onto when Core Web Vitals will not come right any other way. Being a partner is why our builds follow its releases instead of drifting into a private fork.
BigCommerce Partner
We build, migrate and support BigCommerce stores, including the custom apps a catalogue needs when the app store runs out. The partnership is where that work gets a support path when a problem turns out to be the platform's.

What makes ZestIQ stand out from other ecommerce development agencies?
A track record going back to 2006, and a focus on complex, high-demand projects for established ecommerce businesses, set us apart. We deliver robust, scalable solutions and build long-term partnerships.
Is ZestIQ the same company as Zest Logic?
Yes. ZestIQ was founded in 2006 and did business as Zest Logic until 2026, when it took the ZestIQ name. The team, the clients and the work carried over; the name changed to match what we build now, AI products for ecommerce alongside store engineering.
How does ZestIQ ensure that its solutions align with my business objectives?
We tailor solutions to your specific needs and goals. We build precisely what your business requires to drive sales, without overestimating the work or adding features nobody asked for.
Can you explain your approach to long-term client collaboration?
Our team combines deep expertise with an average tenure of six years, and many members have over a decade of experience. We use that knowledge to deliver current solutions and to stay ahead of changes in the field.
Where can I meet you in person?
We have offices in the USA and the EU, so you can visit us there. Our representatives also travel often, so we might be near you. Contact us to arrange a meeting, drinks are on us.
What is your pricing structure and how flexible are you?
We offer middle-market pricing thanks to our team's mix of American and relocated Ukrainian professionals. That lets us keep rates competitive while holding quality, and we are flexible enough to fit different project needs and budgets.
Let’s build something great together!
