01 / CO-FOUNDER WANTED · MARKETING & GROWTH
WE ONLY SCALE
EIGENVECTORS
Eigen Studios is a digital product studio. We build exciting B2C and B2B consumer apps. We need a marketing co-founder to scale them. One partner who has personally taken TikTok and Meta spend from test budget to scale, on real apps in the App Store, with the dashboards to prove every number. We bring the product. You own growth. We split the upside.
We build exciting B2C and B2B consumer apps. We need a partner to scale them. This is a co-founder seat, not a salary. Equity, ownership, and the upside that comes with it. We are not looking for an agency, a consultant, or someone to oversee growth. We want the operator who sits in the ad manager at midnight, kills the losers, scales the winners, and owns the ROAS like it's theirs. Because it will be. Read both columns. Most people belong on the right.
✓ YOU'VE DONE THIS
- →You have personally scaled TikTok Ads and Meta (FB/IG) spend on iOS apps, not managed a junior who did.
- →You held positive blended ROAS while pushing five and six-figure monthly spend, and can recite the numbers by channel and quarter.
- →You drove CPI and CPA down through real creative-testing volume. Kill rates, iteration logs, winners. Not luck on one hook.
- →You are fluent in SKAN 4 and at least one MMP (AppsFlyer, Adjust, Singular): modeled conversions, postback windows, the post-ATT signal you build and trust.
- →You can produce a portfolio of accounts you grew, with before-and-after dashboards, screenshots, spend curves, ROAS by cohort.
✕ DON'T APPLY IF
- ✕You have only run lead-gen or e-commerce and never scaled an iOS app.
- ✕You cannot screen-share the account showing the spend and return you personally drove.
- ✕"Growth" to you means organic, brand, or a deck full of frameworks.
- ✕You want a salary and a defined scope instead of equity and ownership.
Bring the live dashboards. We read SKAN and MMP reports for breakfast. Show us the numbers, not the narrative. If your portfolio is a story instead of a graph, this is not your seat.
Marketing Co-Founder
TikTok + Meta, iOS
As a co-founder, you own growth end to end. You build the creative-testing machine, find the winners, pour fuel on them, and hold ROAS as you scale. You live inside the ad managers and your MMP. You read SKAN like a native language. You are measured on profitable scale, not vanity reach, and you share directly in it.
SEND US YOUR NUMBERS.
Best blended ROAS at what monthly spend. CPI before you arrived versus after. The creative you tested to get there. The accounts you scaled, screen-shared. Proven operators only.
hello@foundersplan.ai · subject "EIGENVECTOR / [your best ROAS at scale]" · include the accounts you scaled, before/after CPI, and one creative you're proud of. This is a co-founder seat, not a job. No generic CVs. No agencies. No theorists.
