Strategy and Vision, Technical Assessments

Meet your strategic objectives. We review, research, define, and execute your product and technology roadmap. Our team analyses and assesses your technological competencies and capabilities to ensure that your strategic objectives are achieved and all stakeholder requirements are met or exceeded.

People and Teams

Achieve your vision by having the right people in the right roles. Our cultural transformation services create highly engaged teams who are motivated to succeed, who can grow both personally and professionally, and who perform at their peak potential. We have an outstanding track record of building and scaling high performance teams while increasing retention.

Executive Development

Enhance or augment your leadership team. The Key CTO team coaches, mentors, and develops the skills of your CTO, CIO, VP Engineering, and/or Chief Architect. We enable your chief technologist to enhance their leadership and communication skills and give them the tools to improve their effectiveness and productivity - ultimately becoming a more effective member of your executive team.

Transition Planning

Ensure a smooth transition. The Key CTO team executes organizational and structural changes to elevate your organization to the next level of performance. We refactor underperforming aspects of Development, QA, IT, and Operations while helping identify and on-board a high quality permanent CIO or CTO. We define and implement the transition plan for your chief technologist, including vetting candidates.

Processes, Tools, and DevOps

Eliminate ambiguity. Key CTO transforms your organization to increase release velocity, improve the quality of deliverables, create and enhance safe visibility into production for dev and QA teams, create transparency for non-technical staff into the technical organization, and promote end-to-end responsibility and shared ownership for all aspects of service delivery.

Security, Compliance, and Disaster Recovery

Understand and mitigate risk. We develop and implement organization-wide policies and processes for information security and privacy as well as Disaster Recovery and Business Continuity Planning. We shorten your sales cycle, mitigate risks, and provide assurance in the context of technical due diligence. We provide a variety of compliance solutions for such cases as PCI.

Data, Machine Learning, and AI

Launch AI-powered products. Our team and partners support your end-to-end data and AI needs: from education, strategy, and roadmapping to custom development, launch, and ongoing coaching. We get you started the right way, accelerate time-to-market, share best practices for AI product building, and develop a strong in-house data competency. From data engineering to data science to deep learning, we can also provide experienced talent to help you meet your delivery goals.
