FAQ
Straight answers to what founders and product leaders ask us most.
Still curious?
Talk to a solution architect — no sales script, just answers.
Most MVPs launch in 10–16 weeks, while complex platforms typically run 6–12 months. After a short discovery sprint we give you a milestone plan with dates you can hold us to — and we report against it every week.
Everything we ship is custom-engineered around your goals and users. We do reuse our own battle-tested internal modules — authentication, payments, analytics, admin tooling — so you don’t pay to reinvent the plumbing.
Product strategy, UX/UI design, web and mobile development, game development, AI and data engineering, QA automation, cloud and DevOps, plus long-term support and growth engineering after launch.
Discovery → design sprints → two-week build cycles with live demos → hardening and launch → measured iteration. You get a dedicated product lead, a shared roadmap and access to our live delivery dashboard throughout.
Yes. We start with a code, architecture and UX audit, then modernize incrementally so your product keeps running while it becomes faster, safer and easier to change.
Send us a message or book a call. Within one business day you’ll hear from a senior solution architect, and within a week you’ll have a scoped proposal with timeline and budget options.
Constantly. We connect products to CRMs, ERPs, payment gateways, identity providers, data warehouses and legacy APIs — with contract tests and monitoring so integrations stay reliable.
Fixed-scope projects, dedicated product squads and team augmentation. Many clients start with a fixed-scope MVP and move to a dedicated squad once the product finds traction.
Yes. Support plans range from business-hours to 24/7 and cover monitoring, bug fixes, OS and store updates, performance tuning and new roadmap features.
Peer review on every change, automated test suites in CI, security and dependency scanning, accessibility checks and staged rollouts with real-user monitoring before anything reaches 100% of users.
