- **Headquarters**: Overland Park, Kansas, United States (based on company website and industry sources)
- **Founded**: 2006
- **Founders**: Marty Bicknell

## Core Business
- **Primary industry**: Financial services – wealth management, investment advisory, and RIA (Registered Investment Advisor) platform.
- **Target customers**: B2B (financial advisors, independent practices) and B2C (high-net-worth and mass-affluent clients served through advisors). Serves enterprise‑scale and independent advisors.
- **Mission or purpose statement**: “Positively impact the lives of many” by creating opportunities for clients, advisors, and communities.

## Products & Services
- **Wealth Management Platform**: A comprehensive suite of services including investment management, estate planning, tax advice, insurance, and wealth advisory backed by in‑house specialists.
- **Mariner Advisor Model**: Advisors join as firm employees with access to national‑scale resources, back‑office support, and collaboration.
- **Mariner Independent**: Advisors own their own practice while partnering with Mariner for infrastructure, compliance, and specialized expertise.
- **Corporate Services**: Support for tax professionals, operations, IT, marketing, HR, legal, and accounting & finance roles within the firm.

## Market Standing
- **Valuation/Market Cap**: Not publicly available (privately held, no disclosed valuation)

  - Active acquisition strategy (multiple firms joining the Mariner family).

## Competitive Advantages
- **Scale with autonomy**: Advisors gain the infrastructure and specialist teams of a national firm while retaining the ability to operate in the model that best fits their goals (employee‑advisor or independent).
- **In‑house expertise**: Dedicated teams in tax, estate planning, insurance, and investment management reduce the need for third‑party outsourcing.
- **Multiple partnership pathways**: Unique flexibility to join as an advisor, via acquisition, or as an independent practice owner—all under the same brand and support umbrella.
- **Culture of collaboration**: Knowledge‑sharing and team‑oriented environment with a focus on putting clients first.

- **Technology and capability investment**: Ongoing updates to business operations infrastructure to allow advisors to focus on clients.
- **Deepening client relationships**: Expanding tax, estate, and insurance services that were often built in response to client needs.

## Why Work Here
- **Culture highlights**: Collaborative, team‑oriented, and driven by a “clients first” mantra. Values diversity and inclusion, and offers a sense of belonging to a shared mission.
- **Remote/hybrid/office policy**: Supports different ways of working—advisors and associates have flexibility to engage in‑office or remotely. “Dress for your day” policy.
- **Notable perks and benefits**:
  - Comprehensive healthcare (medical, vision, dental)
  - Paid time off, 11 paid holidays, parental leave
  - 401(k) with company match
  - Wellness program, HSA & FSA, life & AD&D insurance
