Our Story

Building software since 1993, Zysco shipped one of the App Store's first 3,000 apps and 30+ since. We build our own products too, so we bring product-owner instincts, not just code. Our vision: great software for every business, not just big budgets. Our values: craft over volume — senior-only teams, no handoffs; apps built to last a decade; honest estimates and straight talk; and a bilingual US–France team that builds for global markets natively.

Commonly Asked Questions

Discovery Session: We start with why the app exists, then look outward: the competing apps, their features, and — most usefully — their one-star reviews. Out of that come the MVP pillars, the handful of things version one must do to be worth shipping at all.

Immediate, once we are engaged, we act like we are part of the team.

We keep collaboration simple, transparent, and direct — you work with the people building your app, never through account managers or project-coordinator layers. Kickoff and discovery. Every engagement starts with a working session to align on goals, users, and scope. We turn that into a clear backlog with priorities you control — not a rigid spec that's outdated by week three. Agile rhythm. We work in short iterations (typically 1–2 weeks), each ending with working software you can actually tap through — a TestFlight or internal build on your own device, not screenshots or slideware. You see progress continuously, and course corrections happen early, when they're cheap. Direct communication. Clients get a dedicated channel (Slack, Teams, or email — your preference) with direct access to the developers on their project. We schedule a standing check-in call at a cadence that fits you: weekly for most projects, more often during crunch phases. Our US-based leadership operates on Pacific time, and our distributed team across the US and Europe means questions rarely wait overnight. Transparency by default. You have access to the live backlog, build pipeline, and repository from day one. Estimates are honest, trade-offs are explained in plain language, and if something threatens timeline or budget, you hear about it immediately — not at the invoice. Your tools or ours. We adapt to your stack — Jira, Linear, Trello, Notion — or provide our own lightweight setup if you'd rather not think about it. After launch. We don't disappear at v1.0. Most of our client relationships span years: App Store submissions, OS-update maintenance, feature roadmaps, and ASO are part of how we work, not an upsell. Apps we shipped a decade ago are still running — because we're still here maintaining them. The result: no surprises, early feedback, and an app that ships faster because decisions never sit in a queue.

We measure success the way our clients do: by outcomes in the real world, not hours billed or features shipped. Live in the store, on time. The first milestone that matters is a working app approved and live. With 30+ apps shipped since 2008, we know how to navigate App Store and Google Play review — including the edge cases that stall other teams. On-time, first-pass approval is a metric we track and take pride in. User adoption and retention. Downloads are vanity; retention is truth. We track activation rates, session frequency, and churn to confirm people don't just install the app — they keep using it. As product owners of our own apps, we watch these numbers daily and bring the same discipline to client products. Store performance. Ratings, review sentiment, and keyword rankings tell us how an app competes in the market. Our ASO practice means we measure visibility across localizations — an app that can't be found doesn't succeed, no matter how well it's built. Stability and quality. Crash-free session rates, load times, and OS-update readiness. An app that breaks with every iOS release costs its owner twice — we build and measure for durability, which is why apps we shipped a decade ago are still running. Business impact. Ultimately, an app exists to serve a goal: revenue, leads, compliance, efficiency, customer loyalty. At kickoff we define what success means for your business — subscriptions sold, forms completed, hours saved — and we report against those numbers, not just development velocity. Client relationships that last. Our most honest metric is repeat business. Most of our client relationships span years and multiple projects, because trust compounds. When a client hands us their second app without shopping around, that's success. The pattern behind all of it: we define measurable goals before writing code, instrument the app to track them, and review the data together — so success is a fact we can show, not a feeling.

The most honest measure of our success rate is this: 30+ apps shipped to the App Store and Google Play since 2008, and apps we launched over a decade ago are still live, maintained, and serving users today. In an industry where most apps are abandoned within two years, longevity is our track record. Delivery success. Virtually all our projects reach the store — including apps that other teams struggled to get through review. Our first-pass App Store approval experience spans every major iOS era since 2008, so review rejections and resubmission cycles rarely burn our clients' time. [Optional: add a real % if you can — e.g., "X of our last Y submissions approved first-pass."] ROI drivers. ROI varies by app type, so we define it with each client at kickoff. Typical outcomes we've delivered: Compliance apps: replacing consultant-driven processes costing thousands per year with a subscription app — our own compliance products turn work that takes days into guided workflows completed in hours. Event and productivity apps: measurable time savings per user, driving retention and subscription conversion. Nearshore cost structure: our distributed senior team typically delivers at [X–Y%] below comparable US agency rates, without offshore quality risk — savings that go straight to your ROI baseline. Repeat business as proof. Most of our revenue comes from clients returning for second and third projects or multi-year maintenance relationships. Nobody re-hires a team that didn't deliver value the first time.
