QuinStreet Announces Agreement to Acquire HomeBuddy

Foster City, Calif.— QuinStreet, Inc. (NASDAQ: QNST), a performance marketplace leader in the financial and home services sectors, has signed a definitive agreement to acquire digital home services marketplace SIREN GROUP AG, operating as HomeBuddy. The transaction, finalized on November 30, 2025, will see HomeBuddy integrated into QuinStreet’s Modernize Home Services division, bolstering its ability to guide home services professionals through every stage of client engagement.

The integration of HomeBuddy will enhance Modernize’s platform through these key initiatives:

• Introducing exclusive, high-intent leads distributed via auction format, providing professionals with measurable ROI tools
• Expanding digital media reach through new networks and data integrations to drive client project opportunities
• Growing the professional network to over 2,000 enterprise and regional specialists across 30+ trades
• Strengthening support for QuinStreet’s 360 Finance home improvement lending ecosystem

The U.S. home improvement sector—valued at $522 billion in 2023 and projected to reach $615 billion by 2029—reflects shifting homeowner priorities including remote work adaptations and aging-in-place trends. Professionals in this space allocate $30-$60 billion annually toward marketing, with digital spend rapidly gaining share as clients demand measurable performance outcomes.

“HomeBuddy’s proven capacity to deliver qualified homeowner demand at scale makes this partnership transformational,” said Nikolai von Loeper, CEO of HomeBuddy. “Combining our strengths with Modernize creates unparalleled opportunities for service providers to connect with customers.”

Tim Stevens, QuinStreet COO, added: “This union accelerates our shared vision of performance-driven growth. Professionals gain expanded audience reach and enhanced data tools to optimize operations.”

The acquisition values HomeBuddy at $115 million cash at closing plus $75 million in deferred payments, subject to standard closing adjustments. Financing will include a new credit facility, pending regulatory approvals for an early-2026 closing. HomeBuddy generated $141 million in revenue for the twelve months ending September 30, 2025, with projected adjusted EBITDA contributions exceeding $30 million in the first post-closing year. Further transaction details will be disclosed during QuinStreet’s February 2026 earnings call and SEC filings.
