I’m Jay Leon. I work directly with founders and leadership teams on technology strategy, architecture, and delivery—bringing senior leadership and hands-on expertise in AI agents and knowledge systems.
Based in Northwest Arkansas. Working nationwide.
Most businesses don't have a technology problem. They have a visibility problem — they can't see where they stand or what's coming next.
I've spent twenty years in that gap — as an engineer, platform architect, and technology executive, from Series A startups to Fortune 500 brands, in industries where technology failures aren't abstract.
I work spec-first: every project starts with a written specification, gets built against it, and doesn't ship until it matches. I call that discipline the Enso methodology. And right now I'm deep in agentic AI — evaluating the latest systems, understanding what they do well, and figuring out where they fit your business versus where they don't.
Track record
From CTO and VP of Technology roles to hands-on AI engineering, I connect business priorities with technical decisions, team direction, and delivery.

Lower cost and a simpler stack for an inherited product
I led a three-developer team to stabilize the product, standardize its technology stack, automate recurring work, and reduce hosting costs.

Earlier, at KBS+, I engineered the platforms behind campaigns for BMW, Armani Exchange, and Vera Wang. That work was recognized with an ADC Gold Cube, IAB MIXX Gold, a London International Awards Silver, and the EPA Green Power Leadership campaign award for the BMW ActiveE launch.

From $7,500 Fixed fee · 2–4 weeks
Ongoing access to senior technology leadership without the full-time hire. Architecture calls, vendor evaluation, agentic AI strategy, roadmap decisions — someone who's made these calls before.
I architect the solution, coordinate the build with trusted development teams, and validate every milestone. You get the oversight of a CTO without building the office.
Not sure which model fits? The first call is free: 15 minutes to understand where you are and map the engagement to the actual decision in front of you.
Discuss optionsI’m Jay Leon, founder of Vitasphere — a technology leader with 20+ years architecting platforms, leading engineering teams, and guiding transformation.
Vitasphere exists because most businesses don't need another vendor. They need a senior technologist who's been through it — someone who can evaluate what you have, define where you need to go, and make sure you get there without burning time or budget on the wrong things.
When you work with Vitasphere, you work with me. No hand-offs to junior staff, no slide decks in place of decisions.
A fractional CTO provides senior technology leadership on a part-time or project basis. Instead of a full-time executive hire, you get experienced guidance on architecture decisions, vendor selection, AI strategy, and team structure — calibrated to your actual needs and budget. Read my full breakdown of what a fractional CTO does day to day.
When you're unsure whether your current systems can support your next stage of growth, when you're evaluating a major platform change, or when you suspect your technology spend isn't translating into business value. An assessment gives you clarity before you commit resources.
You work directly with me, Jay Leon, the founder of Vitasphere. Engagements connect senior technology judgment with written specifications, explicit tradeoffs, and milestone validation, informed by more than two decades of hands-on experience.
Yes. Vitasphere is based in Northwest Arkansas, but most engagements are remote or hybrid. I work with companies across the United States — the only requirement is that you're serious about improving how technology serves your business.
I evaluate AI systems based on what they do well today — not what a vendor promises for next quarter. I help you identify where agentic AI creates real value in your operations, where it's not ready yet, and how to build the foundation so you're ready when it is.
A Technology Assessment is a fixed fee starting at $7,500, typically completed in two to four weeks. Ongoing advisory and transformation work is scoped to the level of involvement you need — book a discovery call and I'll give you a straight number.
Duration depends on the scope and level of involvement. An assessment is a focused project; advisory and transformation work may extend over multiple milestones. Timing, fees, and engagement terms are agreed during scoping.
From Series A startups making their first architecture decisions to Fortune 500 enterprises navigating platform migrations. The common thread is a need for experienced technology leadership at a critical moment.
You get a written deliverable with findings and a prioritized roadmap. From there, you can execute independently, bring me on for advisory, or engage Vitasphere for full transformation oversight. No pressure — the assessment stands on its own.
Start with a 15-minute call. No pitch, no slides — just an honest conversation about what's working and what's not.
