Marin Software Incorporated (historically traded on Nasdaq under the symbol MRIN) is a software company in the information sector that focuses on data processing, hosting, and related services for digital advertisers and agencies. According to the company’s public disclosures, Marin Software provides a cross-channel advertising management platform that enables digital marketers to measure, manage, and optimize their online advertising campaigns across search, social, and eCommerce channels. The company states that its mission is to give advertisers the power to drive higher efficiency and transparency in their paid marketing programs that run on the world’s largest publishers.

Marin Software describes its flagship platform, often referred to in its releases as a unified SaaS advertising management platform, as a way for advertisers and agencies to integrate, align, and amplify their digital advertising spend across the web and mobile devices. The platform is designed to help digital marketers convert precise audiences, improve financial performance, and make better decisions by bringing campaign data together in one place. Marin’s technology is used to power marketing campaigns around the globe, and the company notes that it supports clients worldwide.

The company reports that it serves performance-driven advertisers and agencies, emphasizing use cases where marketing teams need to manage large, complex, and multi-channel advertising programs. Marin’s disclosures highlight that its tools are used to manage campaigns running on major publisher platforms, and that its software provides analytics, optimization, and automation capabilities intended to support more efficient allocation of digital advertising budgets.

Business model and platform focus

Based on Marin Software’s own descriptions in its news releases and SEC filings, the company operates as a provider of enterprise marketing software delivered in a software-as-a-service (SaaS) model. Its cross-channel advertising management platform is positioned to help advertisers and agencies manage paid media campaigns in one environment, rather than working separately in each publisher’s tools. Marin highlights that its platform supports search, social, and eCommerce advertising and that it offers AI-powered tools, optimization features, and customizable automation to help marketers manage campaigns more efficiently.

Marin also reports that it has entered into strategic agreements related to search advertising. For example, the company disclosed a Search Ads Innovation Agreement with Google, described as substantially similar to a prior revenue share agreement. These disclosures underscore Marin’s focus on search and performance marketing and its role as an independent technology provider that works with multiple publishers.

Headquarters and history

In its public communications, Marin Software states that it was founded in 2006 and is headquartered in San Francisco, California. The company has also referred to having offices worldwide and supporting clients globally, reflecting an operational footprint that extends beyond its headquarters city. Historically, Marin’s common stock was listed on the Nasdaq Capital Market under the ticker MRIN.

Corporate restructuring, delisting, and bankruptcy

Recent SEC filings and company announcements describe significant changes to Marin Software’s corporate and trading status. The company disclosed that, on June 17, 2025, it received a determination from Nasdaq that its common stock would be delisted due to non-compliance with Nasdaq Listing Rule 5250(c)(1) relating to timely filing of periodic reports. Trading of the company’s common stock on Nasdaq was suspended at the opening of business on June 26, 2025, and a Form 25 was subsequently filed to remove the company’s securities from listing and registration on Nasdaq.

On July 1, 2025, Marin Software filed a voluntary petition for relief under chapter 11 of the United States Bankruptcy Code in the United States Bankruptcy Court for the District of Delaware, thereby commencing a chapter 11 case. The company reported that it continued to operate its business as a debtor in possession during the chapter 11 process, under the jurisdiction of the Bankruptcy Court and applicable law. The company also entered into debtor-in-possession financing arrangements and a restructuring support agreement in connection with a proposed reorganization transaction.

On August 29, 2025, the Bankruptcy Court entered an order confirming the Second Amended Combined Disclosure Statement and Plan of Reorganization of Marin Software Incorporated Under Chapter 11 of the Bankruptcy Code. Marin subsequently filed a Notice of Effective Date, and the company reported that the plan became effective on September 5, 2025. Under the confirmed plan, the company emerged from chapter 11 as a reorganized debtor, with new equity issued to specified parties in accordance with the plan.

As described in the company’s Form 8-K and Form 15, all outstanding shares of common stock of Marin Software Incorporated that had traded under the symbol MRIN, including shares issuable under equity awards, were cancelled and discharged as of the plan’s effective date. The company’s Form 15, filed on September 5, 2025, certifies the termination of registration of its common stock under Section 12(g) of the Securities Exchange Act of 1934 and the suspension of its duty to file reports under Sections 13 and 15(d). The filing notes that, as of the effective date, all outstanding shares of common stock had been cancelled pursuant to the plan.

Implications for MRIN stock

Because the company’s common stock was delisted from Nasdaq following the Form 25 filing and subsequently cancelled under the confirmed chapter 11 plan, the MRIN ticker now represents a former listing rather than an actively traded security on a national securities exchange. The company’s SEC filings caution that trading in the company’s common stock during the pendency of the chapter 11 case was highly speculative and that trading prices could bear little or no relationship to any actual recovery for holders of equity interests. Following the effectiveness of the plan, existing public equity interests were cancelled, and the company deregistered its securities.

For investors and researchers, MRIN is therefore best understood as the historical ticker symbol for Marin Software Incorporated’s former publicly registered common stock, which has since been removed from Nasdaq listing and registration and cancelled in connection with the company’s chapter 11 reorganization.
