Yes, there are several ways to increase a Pokémon's stats in Pokémon Go. You can power up your Pokémon using Stardust and Candy, which increases their level and, consequently, their stats. You can also use Technical Machines (TMs) to change a Pokémon's moveset, improving its battle performance. Additionally, evolving Pokémon can sometimes result in higher IVs for the evolved form, making them stronger.
