The firm operates a diversified financial services platform spanning retail self-directed brokerage, financial advisory, insurance and annuities, investment banking for middle-market companies, and corporate employee stock plan administration. It serves a broad individual investor base alongside several targeted vertical programs: athletes via the Gebbia Sports/Siebert.Endurance division, military personnel and first responders through Siebert.Valor, next-generation investors via Gen W, women investors through a dedicated program, and credit union members and corporate employees via partner referral channels (FFCU, NYBCU) and stock plan partnerships.
Core products include Siebert.Pro (an advanced trading platform with desktop, web, and mobile access), Siebert.NXT Managed Portfolios (discretionary investment advisory delivered through Siebert AdvisorNXT, LLC, a registered investment advisor), insurance and annuity products via Park Wilshire Companies, and RISE Prime Services through RISE Financial Services LLC.

Technology is described as multi-platform brokerage infrastructure supporting desktop, web, and mobile trading alongside managed portfolio allocation, with no public disclosure of AI/ML components.
The firm's revenue mix draws from transaction fees on brokerage trades, recurring fees on advisory and managed portfolios, transaction-based insurance product distribution, professional services fees for corporate stock plan administration, and underwriting participation in public equity and debt offerings. Distribution combines direct online self-service account opening, advisor-assisted phone and in-person consultations, partner referral channels via credit unions, and B2B relationships for stock plan administration. Per company commentary, Siebert Financial Corporation's annual revenue grew from approximately $10 million in 2016 to approximately $100 million in 2025, with retail customers reporting nearly $20 billion in net worth as of Q1 2026. In February 2026, the firm led Arqitech's Series A to bridge decentralized and traditional finance, signaling a strategic option on digital asset infrastructure.
