The specific case study titled "How to Scale Pinterest Ads from $1K to $7K Per Day in Just 5 Days" is not available as a direct, public article or video from my search results. This type of highly specific, rapid-scaling result is often detailed in a paid course, private training, or a specific marketer's internal content.

However, based on general Pinterest Ads scaling best practices, here is a breakdown of the likely core strategies that would be required to achieve such a massive scale so quickly:

🚀 The Core Strategy for Rapid Pinterest Ads Scaling
Achieving a 7x scale in daily spend while maintaining profitability in just five days relies on having a proven creative and funnel before you start, and then using a systematic, aggressive scaling method.

1. Pre-Requisite: The Proven "Hero" Ad and Offer
You cannot scale a bad ad or a weak offer. Before Day 1, the advertiser must have had:

High-Performing Creative: A Pin (likely a video Pin or a high-quality vertical image) that already shows a great Click-Through Rate (CTR) and a low Cost Per Click (CPC) at the initial $1K spend.

A "Hero" Product/Offer: A single product or offer that drives the majority of high-margin sales (high Average Order Value - AOV).

Pixel Optimization: The Pinterest Tag (or Conversion Tag) must be properly set up and warmed up with enough conversion data to feed the algorithm.

2. The Scaling Strategy (Likely 5-Day Playbook)
A rapid scale like this typically involves a combination of two methods: Vertical Scaling (increasing budget on existing ad sets) and Horizontal Scaling (duplicating ad sets and testing new audiences).

Day 1 & 2: Vertical Scaling and Duplication
Action   Purpose
Budget Increase:   Vertical Scale: Increase the daily budget of the top 1-2 performing Conversion Campaign Ad Sets by 20% to 30% every 12-24 hours. This is an aggressive but common scale limit to avoid "shocking" the algorithm.
Top Ad Duplication:   Horizontal Scale: Duplicate the best-performing Ad Sets into new campaigns. This creates new opportunities for the algorithm to find efficient traffic.
New Creative Test:   While scaling, launch a few new ad creatives (different angles, colors, video cuts) at low budget to prevent creative fatigue later in the week.

Day 3 & 4: Aggressive Audience Expansion
Once the core campaigns prove stable at the higher budget, the focus shifts to feeding the machine more audience volume.

Action   Purpose
Lookalike Expansion:   Crucial: Launch new Lookalike Audiences (e.g., 5% and 10% Lookalikes based on purchasers/add-to-carts) and target them with the proven "Hero" creative. Pinterest Lookalikes are a powerful scale engine.
Broad/Interest Testing:   Test very broad audiences (e.g., all women 18-65 in US) or larger, single-interest groups. At this budget, the Pinterest algorithm (like Google's and Meta's) is good at finding conversions even in broad targeting.
Retargeting Boost:   Increase budget on Retargeting Campaigns (Engagers, Visitors, Add-to-Carts) to capture the higher volume of warm traffic being pushed in by the cold campaigns.

Day 5: Reaching the $7K Mark
By day 5, the cumulative effect of the vertical scaling and the massive audience expansion brings the total spend to the $7K target.

Action   Purpose
High-Volume Campaign:   Launch a high-budget campaign ($2K-$3K) targeting a high-percentage Lookalike (e.g., 10%) or broad audience, confident that the pixel's data is strong enough to guide the spend.
Pruning:   Crucial for profitability: Aggressively pause or significantly drop the budget of any new or scaled Ad Set that is performing poorly on ROAS or CPA after 24-48 hours.

Summary of Pinterest-Specific Scaling Elements:
Vertical Pins are Key: The creatives are always vertical (2:3 aspect ratio).

Lookalikes Power the Scale: Lookalike Audiences based on high-value conversions (purchases) are the primary vehicle for going from $1K to $7K.

Visual Consistency: The ads maintain the aspirational, discovery-focused aesthetic that Pinners expect, reducing "ad fatigue" compared to other platforms.

Conversion Goal Focus: The entire strategy is built around Conversion campaigns, giving the platform the best signal for where to find buyers.
