I have an observer for the event when an order is placed by a customer. I tried "sales_model_service_quote_submit_before"

I would like to take a value from the Order and save it to the customer.

For example.

$customer = $quote->getCustomer();
if ($customer) {
  $customer->setData('someValue', $quote->getData('someValue')))

I have also tried

$customerId = $quote->getCustomerId();
if ($customerId) {
  $customer = $customerRepository->getById($customerId);

Can someone please provide an example of an observer to do this correctly?

Try This :-

protected $_customerRepositoryInterface;

public function __construct(
    \Magento\Customer\Api\CustomerRepositoryInterface $customerRepositoryInterface,
    \Magento\Customer\Model\CustomerFactory $customerFactory
) {
    $this->_customerRepositoryInterface = $customerRepositoryInterface;
    $this->_customerFactory = $customerFactory;

public function execute()
    $customerId = 2; // Corresponding customer id
    $customer = $this->_customerFactory->create()->load($customerId)->getDataModel();
    $customer->setCustomAttribute('custom_attribute_name', 'value');
