What Sets Us Apart

Why a2i is Different

Founder-led and intentionally lean — not a staffing firm, not a large consulting company. Senior practitioners with decades of enterprise and Workday ecosystem experience who guide and deliver directly, without layers of overhead between you and the work.

Strategy and Execution in One Team

The same senior advisors who shape your strategy also build the solutions. No handoffs. No information loss. No juniors doing the actual work.

Seniors Who Still Know How to Build

Our team holds deep technical expertise — not just the ability to manage people who have it. We've written the integrations, built the applications, and led the architecture reviews.

Practical AI — Not Hype

We've deployed AI agents and automation in real enterprise environments. We know what creates operational leverage and what doesn't make it past a demo.

Deep Enterprise Platform Experience

Decades across Workday, PeopleSoft, Oracle, and modern application platforms. We understand how enterprise systems actually behave under real conditions.

Boutique Focus, Enterprise Credentials

Founder-led and intentionally lean — you work directly with the practitioners who built this practice. Senior attention and direct access throughout, not just at the kickoff.

Outcomes Over Engagement Length

We engage to create outcomes — then get out of your way. We're not designed to maximize billable hours or extend the engagement beyond what the work requires.

Working With Us

How We Engage

We match the engagement model to the work — not the other way around. Here's how organizations typically work with a2i.

Strategic Advisory

Ongoing or project-based executive technology advisory — technology strategy, platform decisions, and transformation guidance at the leadership level.

AI Readiness & Roadmap

Structured workshops to assess your current state, identify high-value AI opportunities, and define a practical adoption roadmap your team can execute.

Architecture Assessments

Independent review of your current technology landscape — integrations, platforms, application architecture — with a clear picture of risks and a path forward.

Innovation Sprints

Focused, time-boxed delivery for proof-of-concept builds, MVP applications, and AI agent development — moving from idea to working solution quickly.

Workday Platform Advisory

Expert guidance on Workday strategy, platform extensions, integration architecture, and optimization — from a team with deep ecosystem experience.

Custom Application Build

End-to-end design and development of enterprise applications — internal tools, Workday Extend apps, workflow automation, and AI-enabled solutions.

Embedded Technical Leadership

Senior practitioners embedded in your program for delivery governance, architecture oversight, or team enablement — without the cost and commitment of a full-time executive hire.
