Nitreo is automation software: follow/unfollow automation, growth pods, automated welcome DMs and a countdown timer on the pricing page. Sup Growth is a human team doing targeted engagement by hand. If you want the cheapest software plan and are comfortable with automation on your account, Nitreo is cheaper on its entry plan. If you want followers in your city or niche who become customers, with a person managing the account and a 14-day trial, Sup Growth is the alternative built for that.

Nothing automated runs on your account. A person chooses who to engage with in your city and niche and sends every new follower a welcome DM by hand, so the followers are real and local and the messages get replies. The trial is 14 days rather than 7, nothing is charged until day 15, there is a money-back guarantee and a dedicated account manager. Human-paced activity is what keeps an account clear of Instagram’s automation limits.
Ask whether you want software or a person on your account. Follow/unfollow automation is the pattern Instagram’s limits are designed to catch. If you sell to people in a place, a targeted follower with a hand-written welcome message is worth more than several random ones. Take the longer trial and watch who follows. Our free ghost follower checker shows how many of your newest followers look like inactive or bot accounts.
