Mike Castino on Market Makers, Platform Fees, and Building a Boutique ETF Firm
Dakota Rainmaker Podcast
· · 36 min · Hosts: Gui Costin · Guests: Mike Castino
Summary
Mike Castino describes how his career moved from 12 years as an independent futures trader on the Chicago Mercantile Exchange into ETF sales, then into building Sound Capital Solutions as a boutique ETF firm. He says the trading floor taught him the aggressiveness and communication style that later translated into sales, first at Claymore ETFs and then at U.S. Bank Fund Services, where he helped build ETF administrative and custody services from the ground up.
The core argument is that ETF launch and distribution have become far more negotiated and infrastructure-heavy than many issuers expect. Castino says intermediaries can charge flat fees, revenue-sharing arrangements, and data-package fees, and that approval depends on whether platforms want the product, the adviser, and the business case. He argues transparent active ETFs are winning over non-transparent structures because flows, due-diligence coverage, and advisor concerns about holdings visibility all favor transparency.
Castino also says the structural shift from mutual funds to ETFs is accelerating, helped by tax efficiency and the emergence of dual-share-class models that let mutual funds tack on ETF share classes. But he thinks adoption will be gradual because older investors, 401(k) operational frictions, and the need for switching mechanisms still slow the transition. Sound Capital’s own model is deliberately small: four people, a white-label ETF advisory business, and a solutions-provider business aimed at helping issuers pre-launch, launch, and retain assets.
Key takeaways
- Castino says ETF platform access is negotiated, with revenue sharing, flat fees, and data fees all part of the approval process at firms like Schwab and Fidelity.
- He argues transparent active ETFs are gaining over non-transparent structures because organic asset gathering has been weak in the non-transparent category.
- Castino says ETFs have a structural tax advantage over mutual funds because redemptions in mutual funds can force taxable sales of winners.
- He sees dual-share-class ETF models as an important bridge that could speed migration from mutual funds to ETFs once switching mechanics are solved.
- Sound Capital is intentionally small, with four employees, and Castino says the firm wants to remain boutique rather than become a large white-label shop.
