We build [proprietary] software, from first line of code to global scale.
Solidblank is an independent digital product studio based in the UK. We design, build and ship AI-powered mobile and web products from the ground up, driven by modern engineering practice, intuitive design, and our own portfolio of products like Zakkum and Orin.
The complete lifecycle of product development.
Product Engineering
End-to-end software development, from architecture and infrastructure to production-grade applications, built to scale.
Platform Architecture
Robust technical foundations designed for growth: system design, data modelling, and infrastructure that holds under real-world load.
Product Design
Intuitive, considered interfaces. We design the experience alongside the engineering, not after it.
Own Products
Beyond client work, we build and operate our own portfolio of digital products. It is proof that we hold ourselves to the same bar.
Our approach.
Independent by design
We operate independently, which means the solutions we build answer to the problem, not to a client roster or a shareholder deck.
Concept to global scale
We stay involved across the full lifecycle: from the first architectural decision to the systems that carry millions of users.
Engineering-first
Modern engineering practice is not a checkbox for us. It is the discipline that makes everything else durable.
A portfolio of our own.
Alongside our client work, we build and operate our own digital products. It is direct proof of the standard we hold every engagement to.
Zakkum
Turns a chat screenshot into reply suggestions using OCR and an LLM. Available in 22 languages with subscriptions and a referral system, backed by a serverless API.
