“Here you use your skills in a space where facts, policy, and perception intersect—and the noise humbles you. Having sat on both sides of the table on Capitol Hill, I’ve learned that regulation is ultimately about people and incentives; our job is to map those, translate between operators, investors, and public stakeholders, and keep the mission clear. There are many paths to move an initiative forward here, and we coach our teams to frame issues, pressure-test plans, build coalitions, and grow from each iteration. That service mindset—shaped by my public-sector years and nonprofit work—keeps us grounded as we help our people find new solutions and advance their careers.”

Success as Part of a Team
Working with dedicated and capable (and nice) colleagues is essential to being able to move with speed and agility. We try to share wheels, not re-invent them, so individual discoveries can most quickly lead to products or process improvements that have quantifiable and verifiable results in the real world.
“Here you apply legal judgment at the point where rules, incentives, and human behavior intersect—and that humbles you. Risk is rarely a single datapoint; it’s a pattern in people and processes. Our job is to translate that into clear guardrails and practical decisions. Having built our monitoring function and integrated it with compliance, I’ve learned the best control is culture: design controls into workflows, measure, and iterate. There are many ways to resolve a gray-area question here, and we coach our teams to ask second-order questions, document their reasoning, and choose the path that protects clients, the firm, and the market while helping them grow their careers.”

New Ways to Understand the Market
With the world’s data at our fingertips, we pursue challenging problems with passion. We’re curious about how things work, and our exploration often leads to the discovery of patterns of behavior which can be translated into a practical trading strategy. Sometimes we just learn neat stuff.
“Here we don’t just invest—we build with founders. I’m a technophile and a designer at heart; I still love taking things apart, redesigning them, and making the brand sing. What moves markets is behavior change, so we look for the real signals—must-have products, true revenue, and a line of sight to a large, monetizable audience. Then we get hands-on: pattern-match across sectors, bring the right customers and operators to the table, pressure-test go-to-market, and help craft distribution that scales. The next wave—AR/VR-driven visual computing, IoT at scale, and the fusion of data with life sciences and robotics—will reward founders who think boldly and execute even bolder. Our job is to earn their trust and help them turn great ideas into category leaders.”
Barry Schuler
Growth Team, Stellar Chain Capital
“Here I get to fuse machine learning with first-principles investing. We’ll let models surface signals, but we only act after tearing the thesis down through deep diligence—unit economics, counter-party risk, and real-world adoption. In the 2022 drawdown we protected capital with dynamic hedging and disciplined liquidity ladders, a reminder that risk is a process, not a point. Since joining in 2019, my focus has been marrying traditional market structure with blockchain rails—designing compliance-by-design architectures and, more recently, piloting CBDC–DeFi interactions with public-sector partners. There are many ways to tackle an idea here: frame the hypothesis, measure edge, stress-test regimes, and translate the complexity clearly to engineers, investors, and clients so people grow—and the strategy compounds.”
