About Us

Postavant is a boutique private advisory and cultural strategy house for those building the future — one idea, one artwork, one collection at a time.

We offer a unique, refreshing path and strategic alternative to tired, traditional advising. Because we think and see things differently.

Collecting is not simply about buying and selling objects. It’s not about chasing trends or blindly trusting insiders. And it’s definitely not about being pushed inventory to meet someone else's sales quota.

We believe collecting is an extremely rewarding endeavour. It is a path to participating in culture at the highest level and accessing meaningful encounters with extraordinary artists, ideas, places, and people of our time.

Here, you’re not just "buying art." You’re stepping inside a world where the future of culture is shaped.

Through a tailored mix of strategic advisory, exclusive experiences, and expert market intelligence, we empower clients to get closer to the art, artists, people and movements  so they can build enduring collections with clarity and conviction that stand the test of time. 

Why It Matters

We believe collecting is a vital, life-giving, world-shaping endeavor that is personally meaningful and socially impactful.

At its best, collecting is:

Intellectually Stimulating
Emotionally Fulfilling
Financially Rewarding


Collectors aren’t just patrons, they are oxygen for the art world, sustaining artists, institutions, and shaping the very culture we inherit.

We partner with visionary collectors to shape collections that are personally meaningful, culturally significant, and strategically sound.

How We Work

Every acquisition, placement, and recommendation is evaluated through our proprietary framework. It is designed to balance aesthetic vision, conceptual significance, and market intelligence.

  • Aesthetic Excellence — Visual and conceptual quality
  • Conceptual Significance — Depth of ideas, historical contribution, cultural resonance
  • Market Fundamental — Intelligence with value, rarity, and market dynamics

​This framework ensures every decision is grounded, meaningful, and aligned with a collection's long-term cultural and financial impact. 

Because collecting today isn’t about following hype. ​It’s about leading with taste.

Postavant is led by Lauren Rotenberg, PhD, an expert in postwar and international contemporary art.

After years in London’s global art market as a professor, curator, and advisor to private collectors, she created this practice to offer a new client-first model of cultural advising — one rooted in deep art historical and curatorial expertise with sharp market fluency.

Today, we work with a select group of global clients who seek to build collections that matter personally, culturally, and financially. 

​If you are a private individual collector, corporation, institution, or family office, that values building art and cultural collections of enduring quality, you are warmly invited to begin a conversation.
