Strategic Venture Partner — Web3 Markets & Ecosystem
Location: Singapore / Remote
Company: Oryon
Type: Full-time or long-term strategic engagement
About Oryon
Oryon is a hands-on venture capital firm focused on Web3 and AI. We work closely with founders and portfolio companies across strategy, partnerships, fundraising, market expansion, go-to-market execution, product growth, exchange relations, and commercialization.
Rather than operating purely as a financial investor, Oryon takes an active role in helping companies build stronger businesses and navigate complex markets.
We are currently expanding our network in Asia and are looking for an experienced Web3 professional to join us as a Strategic Venture Partner — Web3 Markets & Ecosystem.
The Role
This is a senior, relationship-driven position for someone who has spent significant time inside the crypto ecosystem and understands how projects, founders, exchanges, investors, market makers, funds, and token ecosystems interact.
You will work directly with the Oryon team and selected portfolio companies, helping identify opportunities, evaluate projects, develop strategic relationships, and support companies through key stages of growth.
The role combines venture strategy, ecosystem development, market intelligence, partnerships, and direct founder engagement.
Responsibilities
Identify promising Web3 companies, protocols, infrastructure projects, and emerging market opportunities.
Build and maintain relationships with founders, investors, exchanges, market makers, ecosystem funds, family offices, and other industry participants.
Participate in evaluating early-stage and growth-stage opportunities.
Analyze token economics, market structure, liquidity dynamics, competitive positioning, and ecosystem incentives.
Support founders with fundraising strategy and introductions to relevant strategic partners.
Help portfolio companies develop exchange, liquidity, ecosystem, and institutional relationships.
Identify strategic partnership opportunities across Asia and global Web3 markets.
Participate in discussions around new market opportunities, emerging narratives, and sector positioning.
Represent Oryon in selected private industry discussions, founder meetings, conferences, and ecosystem events.
Contribute independent investment and market perspectives to internal discussions.
Develop new commercial and strategic opportunities for both Oryon and its portfolio companies.
Who We’re Looking For
We are particularly interested in candidates with deep practical exposure to the crypto industry rather than purely theoretical experience.
A strong candidate may have experience in one or several of the following areas:
venture capital or crypto investment;
digital asset markets;
exchanges;
OTC and institutional markets;
market making;
token launches;
ecosystem development;
protocol partnerships;
crypto business development;
founder advisory;
private market transactions;
DeFi;
Web3 infrastructure.
You should have a strong understanding of how value moves through the crypto ecosystem and be comfortable speaking directly with founders, executives, investors, traders, and institutional counterparties.
Ideal Profile
5+ years of relevant experience in crypto, Web3, venture, fintech, or digital asset markets.
Strong existing network within the Web3 ecosystem.
Experience evaluating projects beyond surface-level narratives.
Good understanding of tokenomics, liquidity, exchanges, market cycles, and crypto-native business models.
Comfortable forming independent opinions and challenging consensus.
Strong negotiation and relationship-building skills.
Ability to operate independently in a distributed international environment.
Fluent professional English.
Singapore or broader APAC network is a strong advantage.
What Makes This Role Different
This is not a traditional corporate business-development role.
You will have significant exposure to founders, emerging technologies, new projects, strategic transactions, and investment discussions across the Web3 ecosystem.
We are looking for someone who already thinks like an operator and market participant and wants to work closely with companies rather than simply observe them from the outside.
What We Offer
Fully remote international working environment.
Direct interaction with founders and senior Oryon team members.
Exposure to early-stage and growth-stage Web3 companies.
Significant autonomy over partnerships and new opportunities.
Competitive compensation based on experience.
Performance-based upside for exceptional contributors.
Opportunity to develop into a broader Venture Partner role as Oryon expands.
Website: https://oryon.team
Oryon is currently operating in stealth mode, so only limited information about our activities is publicly available. Additional information about the firm, role, and collaboration structure will be discussed directly with selected candidates.
