Upload the gift ads to the Holiday ad set.
Lena
Before I upload: 6 of these ads have the headline from your evergreen ad, “Hydration, all year long,” not the gift copy, “The gift they’ll use every day.”
Want me to fix all 6 first?

Research what customers say about Trailhead packs. Why do people hesitate at the price?
Lena
Your research on Trailhead is done: 6 findings from 148 verified quotes, from Reddit, reviews and forums.
Strongest pattern: the price feels fair once people trust the pack will last.

Packs · Why people hesitate at the price
Run Oct 28, 2026Summary
Buyers compare Trailhead to packs that failed them. The price reads as fair once they believe the pack will outlast the last three. Most doubt comes from not knowing how the warranty works.

Why it’s named Lena
Lena is the Head of Growth at Iris Labs. She’s sophisticated and hard to impress.
Internally, we called it the Lena Test: Would she actually use our tools in her workflows? We knew we had nothing until the answer was “hell yes.”
Today, she ships 100% of her ads through us.

FAQs
What is Lena?
Lena is your marketing cheetah—a fast, intelligent tool that connects with familiar AI assistants like Claude, ChatGPT, or Codex. Lena helps you read Meta results, build and edit campaigns, manage your creative library, and run brand research.
Do I need to know how to code?
No coding is required. Simply copy the prompt from this page and paste it into your AI assistant. The assistant will guide you through setup and sign-in. For apps like Claude, just add Lena as a connector first.
Which AI tools does Lena work with?
Lena is compatible with any AI assistant that supports MCP connectors, including Claude (web, desktop, and phone), Claude Code, ChatGPT, and Codex.
What can Lena see in my ad account?
Lena can see how your campaigns, ad sets and ads are structured and set up, from objectives and budgets to bidding, targeting, placements and schedules. For each ad, she sees the copy, link, call to action, images and videos, including what’s shown and said in them. She gets the same numbers you see in Ads Manager, like spend, impressions, reach, clicks, conversions, revenue and ROAS, by campaign, ad set or ad, and by age, gender, location, placement, device or day. She also sees your custom, lookalike and saved audiences, estimates of how many people a new targeting setup would reach, your lead forms, and the Facebook Pages, pixels and Instagram accounts the ad account uses.
What can Lena change in my ad account?
Lena can build new campaigns, ad sets, creatives and ads, and rename the campaigns, ad sets and ads you already have. She can also upload images and videos to the ad account’s media library, create lookalike, website-visitor and engagement audiences, and create new lead forms or archive and restore existing ones.
Can Lena spend money without my approval?
No. Everything Lena builds starts paused, and only you can turn it on in Ads Manager. Lena can’t turn anything on or off, change an existing budget, or delete anything.
Which ad platforms does Lena support?
Lena currently works with Meta, supporting both Facebook and Instagram ads.
Can my whole team use Lena?
Yes. Lena shows your organizations, ad accounts, and team members, and lets you set a default organization. You can share links for teammates, editors, or clients to upload or view files, and you can email or revoke those links at any time.
How long does brand research take?
Typically, a brand research run takes 20 to 40 minutes. Lena checks for previous runs first, so you don’t wait for research you already have.
Why is the cheetah green?
Real cheetahs run to survive. Lena runs to help you make money—that’s why she’s green.
