Modern Slavery Statement
Introduction
This Modern Slavery Statement (this “Statement”) is made on behalf of Klaviyo, Inc. and its subsidiaries (together, “Klaviyo,” “we,” “us,” or “our”) in compliance with global modern slavery legislation including the UK Modern Slavery Act 2015, the Australian Modern Slavery Act 2018 and the California Transparency in Supply Chains Act 2010. This Statement sets out the steps Klaviyo has taken in its fiscal year ended December 31, 2024 to ensure that its supply chain and operations are free from modern slavery and human trafficking.
Our Business
Klaviyo is the only CRM built for B2C brands. Powered by its built-in data platform and AI insights, Klaviyo combines marketing automation, analytics, and customer service into one unified solution, making it easy for businesses to know their customers and grow faster. Klaviyo was founded in 2012 and is headquartered in Boston, Massachusetts. Our global offices are located in the United States, UK, Australia, and Ireland.
Klaviyo, Inc. is a Delaware corporation. Klaviyo’s subsidiaries include Klaviyo Ltd, a private limited company registered in England and Wales, and Klaviyo Australia Pty Ltd, an Australian proprietary limited company, each of which is wholly owned by Klaviyo, Inc. Klaviyo, Inc. does not have any other subsidiaries or group companies based in either the UK or Australia.
Our Supply Chain
Given the nature of our business, we have a relatively short supply chain. Our SaaS platform is developed and maintained by our employees. Our suppliers predominantly supply cloud and SaaS services, professional services (for example, accounting, audit, legal, and marketing services), hardware, and office equipment. We also engage a limited number of contractors, most of whom are based in the United States.
Risk of Modern Slavery and Human Trafficking
Given the nature and location of our business, operations, and supply chain, as well as the measures we take to prevent modern slavery and human trafficking in our business and across our supply chain (described below), we believe that the risk of modern slavery and human trafficking in our supply chain and operations is low.
Actions taken to Assess and Address Risks of Modern Slavery and Human Trafficking
Klaviyo is committed to maintaining a work environment that is free from human trafficking and slavery. We do not tolerate or condone modern slavery or human trafficking in any part of our global organization or supply chain. In line with this commitment, we take the following measures to prevent modern slavery and human trafficking in our business and across our supply chain:
- Engaging Suppliers – We conduct due diligence when engaging vendors, service providers, suppliers or other parties providing goods or services to Klaviyo, including screening against global sanctions lists and watchlists and conducting adverse media searches.
- Contractual Obligations – We include contractual obligations in our supplier services agreements globally to include specific reference to compliance with applicable modern slavery laws. This ensures our suppliers are contractually bound to comply with applicable modern slavery laws and promotes ethical business practices.
- Modern Slavery Guidance and Training – Our legal and compliance teams provide modern slavery training targeted at key personnel in an effort to equip our teams with the knowledge and tools needed to identify potential risks, ensure compliance with relevant legislation, and take proactive steps to prevent any occurrences of modern slavery and human trafficking in our operations or supply chain.
- Annual Ethics Week – Our annual employee “ethics week” reinforces our commitment to ethics and compliance, educates and reminds our employees of our core values and expected behaviors, and raises awareness of ethical standards and reporting mechanisms.
Klaviyo also has a number of related policies and procedures that underpin our commitment to ethical business practices and emphasize accountability and transparency within the organization. These include:
- Code of Conduct – Klaviyo’s Code of Conduct (“Code”) outlines the policies, laws, rules, and regulations which all employees, officers, directors and independent contractors are required to abide by, and is attested to on an annual basis. Our Code also outlines how individuals can submit questions or raise concerns of suspected violations of our Code or any other Klaviyo policy through our Ethics & Compliance Helpline.
- Supplier Code of Conduct – We have implemented a Supplier Code of Conduct that sets out the expectations we have of our suppliers with respect to the human rights of workers, health and safety, and improper conduct reporting, amongst other topics. We require all of our suppliers globally to read, understand, and comply with our Supplier Code of Conduct.
- Whistleblower Hotline – Klaviyo has in place a third-party hosted Ethics & Compliance Helpline to allow for anonymous reports of possible violations of law or policy within our business and supply chains without fear of retaliation, including any concerns or suspicions of modern slavery or human trafficking. The helpline is available 24/7 and employees worldwide can report concerns online or by telephone.
Assessing Effectiveness / Further Steps
Klaviyo recognizes that combating modern slavery and human trafficking is an ongoing effort. We are committed to promoting ethical business practices and regularly reviewing and assessing the risk of modern slavery and human trafficking in both our operations and our supply chain, as well as the effectiveness of the measures we have put in place to address same. Our operations are tightly integrated, and our group companies remain in close contact regarding all issues, including those related to modern slavery and human trafficking.
We intend to take the following further steps to combat the occurrence of modern slavery and human trafficking:
- Continue to keep apprised of legal requirements and industry practices regarding modern slavery in the countries in which we operate, and implement any additional measures, as required.
- Continue to engage in due diligence when engaging suppliers, including those providing physical goods.
- Engage in additional training and awareness initiatives.
We will monitor and report on our progress in the above areas in our next Modern Slavery Statement.
