Loved by the teams we build with
The people who signed off on the work, in their own words.
Sample quotes shown. Replace them with real client feedback before launch.Promettis rebuilt our platform from the ground up and cut page loads by 70%. They felt like an extension of our own team.
Their pentest team found critical issues two prior vendors missed. The report was clear enough that our devs fixed everything in a week.
From discovery to launch in 11 weeks. The product strategy work alone saved us months of building the wrong features.
Zero-downtime migration to Kubernetes, exactly as promised. Our deploy time went from hours to minutes.
The mobile app they shipped has a 4.8 rating and our retention doubled. Genuinely world-class engineering.
Responsive, transparent, and technically excellent. They are now our default partner for anything that matters.
Questions, answered
The things clients ask before they sign. If yours is not here, just ask us.
Everything from greenfield MVPs to scaling and securing established platforms — web apps, mobile apps, cloud infrastructure, and AI features. If it involves shipping quality software, we can help.
With a free 30-minute call to understand your goals. If there is a fit, we run a short discovery phase and give you a written scope, timeline and fixed estimate before any development begins.
Yes. Many clients come to us only for VAPT. We test web apps, APIs, mobile apps and cloud setups, deliver a prioritised report and retest your fixes at no extra cost.
Fixed price for well-defined scopes, and monthly retainers or time-and-materials for ongoing product work. Every proposal shows exactly what is included, so there are no surprise invoices.
Yes. Once invoices are paid, all source code, designs and documentation belong to you. We work in your repositories from day one, so you always have full access.
Yes. Our maintenance plans cover monitoring, security patching, bug fixes and a monthly block of hours for improvements, with response times written into an SLA.
Absolutely. We often embed engineers or designers into in-house teams, follow your processes and tools, and hand over cleanly when the work is done.
A focused MVP usually takes 8–12 weeks. Larger platforms run in phases of 3–6 months. A security assessment is typically 5–10 working days.
