Peter Piotrowski Joins Sinistar as Advisor for U.S. Insurance Growth

Sinistar is bringing a veteran claims executive into its effort to expand in the U.S. temporary housing market. Peter Piotrowski, who has more than 35 years of experience across insurance carriers, specialty coverage and technology-focused insurance businesses, joined the company as a strategic advisor on November 2, 2026.

The appointment connects Sinistar’s growth plans with an executive whose career has covered claims operations for both mainstream property insurers and high-net-worth customers. His brief includes supporting U.S. expansion, market entry strategy, insurer relationships and product development. The company says it wants to serve needs ranging from standard homeowners claims to complex, high-value residential losses.

Experience across claims operations

Piotrowski most recently served as chief claims officer at Hippo, where he led changes to the company’s claims organization. Sinistar says that work included advancing digital capabilities, artificial intelligence workflows, operational efficiency and customer service. The company also says claims quality, customer satisfaction and employee engagement improved under his leadership, though it did not provide measurements for those outcomes.

Before Hippo, Piotrowski spent six years as chief claims officer at Vault, a specialty insurer serving the high-net-worth personal insurance market. That work involved claims for affluent customers with complex property exposures and expectations for personalized service and timely resolution. Earlier leadership roles at The Hanover Insurance Group, AIG and Chubb gave him experience in both broad personal insurance and specialty markets.

That background is relevant to temporary housing because a placement has to fit the circumstances of a particular loss. A household’s location, needs and the nature of its property damage can affect what housing is suitable and how quickly an insurer can arrange it. Sinistar’s pitch is that technology can improve the visibility and coordination involved for insurers, adjusters and displaced customers.

Housing as part of the claims process

Temporary accommodation can shape a policyholder’s experience while a property remains uninhabitable. It also sits within the insurer’s broader claims workflow: delays or mismatches can mean more coordination for claims teams and can affect how long a claim takes to resolve. Sinistar argues that the speed, quality and suitability of housing arrangements matter to both customer service and insurers’ operating costs.

Those are potential benefits rather than quantified results in the announcement. It gives no figures for placement times, housing costs, claim duration or customer retention, and does not describe how Sinistar measures performance against existing arrangements. The practical test for the platform will be whether it can reliably match housing to varied claims while giving insurers and adjusters useful visibility into the process.

Piotrowski said temporary housing is an important part of the customer experience, particularly when families have to leave their homes after a major property loss. He cited Sinistar’s use of technology and transparency as reasons for joining, and said he sees an opportunity to bring its approach to the U.S. insurance market.

Advisory role and next steps

Founder and CEO Alexis Vertefeuille said Piotrowski’s experience could help the company strengthen its platform, develop insurer relationships and extend its U.S. presence. In the advisory role, Piotrowski is expected to work with Sinistar’s leadership on those priorities as well as product development.

The appointment signals where Sinistar sees room to grow: connecting housing arrangements more closely to claims operations. Piotrowski’s experience across large insurers, specialty coverage and an insurtech company gives him a broad view of those workflows. The announcement, however, does not identify expansion targets, planned product changes or specific insurer relationships.

For insurers, the question is whether a technology-led service can make housing placements easier to coordinate without losing the personal attention that complex losses may require. For displaced customers, the relevant outcome is whether the accommodation fits their circumstances and arrives when needed. Sinistar’s next phase will make those operational results more important than the breadth of its stated ambitions.

Sinistar describes itself as an artificial intelligence-enabled insurance technology platform and temporary housing service provider for insurers and adjusters. Its platform is designed to help users find housing and coordinate placements with more visibility and control. More information is available at www.sinistar.com.
