New playbooks every week

Every week, we surface a new proven growth playbook. Here’s what just dropped.

See all weekly drops
01
Cluely

Cluely

New

Creator-employee distribution

Coach-and-clone format propagation

“When one format hits, all 60 creators copy it — that day.”

Internal content coaches review every video and redirect creators in real time. When a format wins, the entire creator network is told to replicate it immediately. One winning hook becomes 60 simultaneous posts.

~80M views/month · daily cadence

Cal AI

Cal AI

App Store optimization

Download velocity spike to trigger App Store rank algorithm

“Apple weights recent velocity. Engineer the spike.”

Cal AI concentrated 150 creators posting in the same 7-day window. The velocity spike pushed it to #1 fitness/health. Organic discovery compounded on top at zero extra CAC.

#1 App Store fitness/health · 66K+ reviews

03
Kleo

Kleo

Webinar / live

Run 20/20/20 LinkedIn Live as launch event

“Demonstrate expertise first, then show the product, then ask for money.”

20 min pure education → 20 min live demo → 20 min pitch with hard scarcity: 500 spots at 50% lifetime discount. LinkedIn auto-notifies all followers. Kleo hit $30K MRR in 4 days from a single live.

HeadshotPro

HeadshotPro

Parallel launch experiments

Launch two products simultaneously, follow the higher CVR

“Press is a false signal. CVR is the north star.”

Danny launched HeadshotPro and Deep Agency on the same day. Deep Agency got the press. HeadshotPro had 10× higher CVR. He doubled down entirely. Marginal cost of the second product is near zero when the tech stack is shared.

10× CVR delta · full pivot in weeks
