| Example product review | Setup took just a few seconds, and it works right away. All my pixels from GTM are now server-side and perfectly connected. So much money saved on ads. | "Not all of their offerings were as helpful for a subscription brand with one product...they'll do a better job anticipating edge cases like ours in the future." | "We were having difficulties with accurate and consistent revenue attribution...With Littledata implemented, we now get consistent and accurate revenue attribution." |
| Example support review | The support was very fast to answer our questions and super helpful. Just be careful to check that the events don't trigger twice. | "Customer support is lacking, and responses are slow... not what I expected from a company of this caliber." | "Customer support is absolutely amazing... you can never go wrong when an app does what it says and tacks on great service!" |
