Who We Are

Three co-founders, three practices, one platform.

Blue Skye Development, Inc. was founded as a technology commercialization and industrialization adviser, helping global innovators cross the chasm from concept to functioning enterprise — advanced materials and clean energy, and the industrial real estate that lets those projects break ground. That advisory core is now one of three practices under the Blue Skye platform.

Alongside it sit two more specialist practices, each brought in by a co-founder with decades of independent expertise in their own field: a private gemology practice built on more than thirty years of gem identification, grading, and buyer education, and a fine art advisory practice grounded in the auction world. Each practice is still run by the specialist who built it.

What ties the three together isn't a shared industry — it's a shared standard: rigorous evaluation, discretion, and hands-on expertise, applied to materials and real estate, to gemstones, and to fine art alike.

How the platform fits together

  • Independent PracticesEach co-founder runs their own practice — energy & real estate, gemology, or art — with full specialist depth in their field.
  • Shared DisciplineRigorous evaluation, capital structuring where relevant, and long-standing professional relationships carry across all three.
  • One PlatformA single, trusted point of contact for partners who need any of the three, or all three at once.
  • Built on TrustEvery engagement is handled with the same discretion and care, whatever the asset.
What We Do

Three practices. One standard of expertise.

Each practice stands on its own specialist merits, led by the co-founder who built it, and each benefits from the same platform of trust, discretion, and infrastructure.

Our Approach

How we take on a project, whatever the practice.

01

Evaluate

Technical, commercial, or connoisseurship review — a technology, a site, a stone, or a work of art, assessed by the specialist who knows it best.

02

Structure

Capital, partnerships, or sourcing pathways are built to fit the project's specific market and the client's goals.

03

Develop

Industrial, real estate, gemology, or art work is carried out hands-on, alongside trusted partners in each field.

04

Deliver

Handoff to the long-term owner, buyer, or operator — with the same discretion and care from start to finish.
