As private markets make up a larger share of portfolios, the cost and oversight required to manage them has grown too, driven by manual processes, fragmented portals, and technology that hasn’t kept pace. The result is outdated and labor-intensive workflows, with a single private equity fund requiring over 5,500 clicks across its 10-year lifespan. This disconnect makes it imperative that technology evolves in tandem. Soura will build on Arch’s standing as the private markets platform of choice, driving automation across additional private markets workflows, while surfacing the trends, performance drivers, and insights allocators need. With a goal of driving down the cost of managing alternative investments and powering better decisions, Soura will also help Arch put novel and secure AI tools in the hands of customers, who are clamoring for advantages as they navigate private markets.

Soura has spent his career building and scaling platform infrastructure and engineering teams through periods of rapid growth. He joins Arch from mortgage fintech Better.com, where he led engineering, and previously served as CTO of proptech firm VERO. A recognized technology leader, Soura is a frequent speaker on AI and engineering and was named a 2025 HousingWire Tech Trendsetter for his work advancing AI-powered financial infrastructure. He brings that experience to lead Arch’s product and engineering teams, with a focus on making private markets more transparent and simpler to navigate.

“Private markets are entering a new era,” said Ryan Eisenman, Co-Founder and CEO of Arch. “For years, we’ve helped investors automate the operational work behind private investments. The opportunity is much bigger. We believe the future of private markets will be built on trusted infrastructure that doesn’t just centralize information or automate work, but helps investors understand risk, operate with confidence, and make better decisions. Keith is exceptional at building systems that get stronger as they scale, which matters as we develop Arch to proactively surface the information and intelligence allocators need.”

With Soura leading engineering, Arch is working to give private markets investors the same real-time visibility into their alternative assets that they have long expected from public-market holdings. That vision extends beyond automation to creating insights in a platform that connects investment decision-makers, clients, advisors, accounting, asset managers, and their data, making alternative investments easier to manage, understand, and successfully integrate into a portfolio.

“Private markets have always been data-rich and insight-poor, not because the information doesn’t exist, but because the infrastructure to surface it hasn’t,” said Soura. “Arch already leads on the operational side. What excites me about this moment is building the layer on top: a system intelligent enough to tell you what matters across your portfolio before you’ve had to ask. That’s what modern AI actually makes possible, and Arch is in the right position to build it.”

Investors trust Arch to simplify K-1 and document collection, capital calls, and reporting across private equity, venture capital, hedge funds, real estate and other private investments. The platform supports $460 billion in private assets across 575 leading allocators, including Fortune 100 financial institutions, four of the top-20 global banks, and eight of the top 20 accounting firms.
