AI-native, so you get results faster.
AI is part of how we design, build and test, with experienced people accountable for every decision.
AI product development
Assistants, retrieval, agents and workflow automation designed for usefulness, control and production operation.
Explore AI Development →AI-assisted engineering
AI speeds up research, prototyping, implementation, testing and documentation. Experienced people stay accountable.
How we build →AI feasibility and discovery
Prove the riskiest part first: a focused prototype tested against agreed acceptance criteria before the MVP.
Ways to start →AI readiness check
Twelve release gates from our AI prototype audit. Answer them and see what to fix before production.
Check your prototype →Delivery approach
A Visible Path from Decision to Working Software.
A shared view of scope, evidence, dependencies and acceptance criteria keeps the next decision visible throughout delivery.
Design the Path
Make scope, experience, architecture, integrations and acceptance criteria visible.
Build in Increments
Deliver reviewable software with automated checks, regular feedback and transparent progress.
Launch and Operate
Plan monitoring, support ownership, rollback and the next product decision before release.
Work with the Team You Already Have
We can own a defined workstream or collaborate with internal product, design and engineering teams.
Keep Product Knowledge Transferable
Architecture, source code, documentation and operating knowledge are structured for client ownership under the agreed contract.
Control Delivery Risk
Scope, dependencies, acceptance criteria, testing and release controls remain visible throughout delivery.
Ways to start
Start small. Decide with evidence.
A focused first step that ends with something you can evaluate, before you commit to a larger build.
Engagement & pricing →Technical assessment
Best when: You have an existing product, codebase or legacy system.
- Codebase and architecture review
- Risks, technical debt and integration map
- Modernization or extension plan
Product discovery
Best when: You have a business problem and need a responsible build decision.
- Problem statement and workflow map
- First-release scope with acceptance criteria
- Architecture direction and delivery plan
Feasibility prototype
Best when: A key technical or AI question must be answered before the MVP.
- A focused prototype of the riskiest part
- Evidence against agreed acceptance criteria
- A go, change or stop recommendation

How much does it cost to work with OpenGeeksLab?
Every project is scoped individually. We estimate by capability and uncertainty, not by counting screens, and stage the budget so each step ends with something you can evaluate. See Engagement & pricing for what influences cost.
How long does it take to build a product?
It depends on scope, integrations and the evidence you need before release. On past projects, a four-person team delivered a beta telemedicine MVP in two weeks, and a five-person team delivered a marketplace web product in six months and its mobile app in four.
What technologies do you work with?
Our case studies include React, Next.js, Angular, React Native, Swift, Kotlin, Node.js, NestJS, Java, PHP, MongoDB, MySQL, Redis, Elasticsearch and AWS. We choose the stack that fits the product, risk and operating reality.
Can you handle AI projects as well as traditional software?
Yes. We build AI assistants, retrieval and agent workflows, and add AI to existing products, alongside web, mobile, SaaS and modernization work.
Do we have to begin with discovery?
No. A focused discovery is useful when requirements, feasibility or risks need clarification. A well-defined project or established product workstream can move directly into delivery planning.
Can you work with an existing product or internal team?
Yes. The engagement can start with a codebase and architecture review, a defined product workstream, modernization, integration or additional engineering capacity alongside your team.
Can AI be added to existing software?
Often, yes, but the useful starting point is the workflow and available data. We assess feasibility, integration, privacy, evaluation, cost and fallback before recommending an AI implementation.
Who owns the software and source code?
The engagement is structured so the client can own and operate the delivered product, source code and project knowledge under the agreed contract.
