What Brokerage Platform Option does

First Southern, LLC is a privately held, boutique broker-dealer and registered investment adviser founded in 2010 in Alpharetta, Georgia, by W. Heath Hawk and Vasileios A. Sfyris. The firm provides a broad spectrum of investment banking and brokerage services to individual investors, registered investment advisors, and corporate and institutional clients across the United States and Puerto Rico, with offices in Alpharetta, GA and Guaynabo, PR. First Southern is a registered broker-dealer with the SEC and a member of FINRA, MSRB, and SIPC, with clearing and custody provided by Pershing LLC and excess SIPC coverage through Lloyd's underwriters.

The firm's offering is organized around four service pillars: Wealth Management for individuals (brokerage, managed solutions, retirement, insurance); Institutional Sales and Trading in fixed income; Invest Advisor Solutions providing outsourced portfolio construction and trade execution for RIAs; and Investment Banking / Public Finance covering municipal underwriting, M&A advisory, valuation, and capital sourcing. The cornerstone business is trading fixed income securities, with particular specialization in investment grade and high yield municipal bonds in both primary and secondary markets. The firm emphasizes a research-oriented approach to identifying distressed and special-situation municipal credit.

The revenue model combines transaction-based brokerage commissions on securities executed for retail and institutional clients, professional service fees from investment banking engagements (underwriting, M&A, valuation), and recurring advisory and management fees on wealth management portfolios. Distribution is relationship-led: dedicated sales teams for institutional, RIA, and high-net-worth segments supported by a separate institutional trading desk. There is no proprietary technology platform; clients access accounts through netxinvestor.com, and trading relies on electronic and traditional execution channels. Pricing is not publicly disclosed and is structured per representative. The firm has approximately 11-50 employees, with the management team composed of industry veterans from UBS, Santander, BB&T, PaineWebber, Merrill Lynch, Citigroup, and Banco Popular.

Direct peers

• H. J. Sims: HJ Sims is a privately held broker-dealer specializing in fixed income and municipal underwriting. It is the most direct comparable — multiple First Southern producers came from HJ Sims (Luis Currais, German Ramirez de Arellano, José Antonio Colberg, Luis Sanchez Paredes) and both firms compete for the same RIA and institutional fixed income wallet.
• Hilltop Securities: Hilltop Securities is a regional broker-dealer with a strong municipal underwriting, public finance, and institutional fixed income trading practice. Comparable to First Southern in product mix (wealth, institutional trading, public finance) but at significantly larger scale.
• Loop Capital Markets: Loop Capital is a minority-owned boutique broker-dealer with a strong municipal underwriting and institutional fixed income practice. Direct overlap with First Southern's municipal specialty and similar relationship-driven model serving RIAs and institutional accounts.

• Cabrera Capital Markets: Cabrera Capital Markets is a minority-owned boutique broker-dealer with deep municipal underwriting and institutional fixed income expertise. Comparable in scale, product mix, and target client base to First Southern's institutional trading and public finance platform.

Broad incumbents

• Janney Montgomery Scott: Janney is a mid-Atlantic regional broker-dealer with wealth management, fixed income, and public finance practices. Comparable across wealth and institutional fixed income offerings but larger scale and broader geographic footprint than First Southern.

Regional players

• Popular Securities: Popular Securities is the broker-dealer affiliate of Banco Popular in Puerto Rico.
