Trusted by teams at
QuadCore is a small company of product designers, engineers and growth operators. We build scalable websites, admin platforms, AI-powered systems and the automation rails underneath — for founders and teams who want the real thing, not a template.
Scalable applications built with modern frameworks designed for performance and long-term maintainability.
Intelligent features, LLM integrations, workflow automation, and AI-powered systems that transform how businesses operate.
Custom storefronts, checkout flows, inventory systems, and the backend infrastructure that powers online commerce.
Purpose-built control panels and CMS platforms that give businesses real operational control over their digital assets.
A complete rebuild of a legacy patient portal serving 500k+ users, delivered in 4 months.
A real-time investment tracking dashboard for a venture capital firm managing $200M in assets.
Migration of 15 services from Heroku to AWS with zero downtime and 40% cost reduction.
QuadCore rebuilt our patient portal in 4 months. The new system handles 3x the traffic with half the infrastructure cost. Their team felt like an extension of ours — same Slack channels, same standups, same commitment to quality.
We have recommended QuadCore to five of our portfolio companies. They consistently deliver on time, communicate proactively, and their code quality is among the best we have seen. A rare find in the agency world.
QuadCore took our idea from a napkin sketch to a top-10 finance app in under 6 months. Their mobile team is exceptional — they not only built the app but helped us define the product strategy.
Two weeks with your team, your data and your customers. We leave with a written plan, not a pitch deck.
Systems, flows and a reviewable prototype. You see real screens by week three, not a mood board.
Weekly shipping cadence. Code, infra, evals and rollout plan written by the people who designed it.
A clean handover, or an ongoing retainer if you want us to keep the lights on and the roadmap moving.
Send us a short note — a Loom, a Notion doc, or two sentences is plenty. If it's a fit, we'll set up a 30-minute call with a partner. No sales funnel, no SDR, no drip sequence.
