Yuliya Lennox
A decade of growing consumer subscription apps, starting as (effectively) CMO at BetterMe, then Eva Learn English, Palta (parent of Flo), Replika, Higgsfield (AI video) and Solid Starts (baby-feeding). Known for the “make ugly ads” philosophy.
Strong on: performance-creative philosophy, brand vs performance trade-offs, localisation as a testing and growth lever, organic-heavy apps hitting a ceiling, the ethics of web-quiz growth.
Bias to keep in mind: opinions are strongly stated and mostly anecdotal (few numbers); much of her experience is Eastern-European performance-marketing culture at high spend. She openly promotes Higgsfield, a former employer.

Notes citing Yuliya Lennox
- Creative volume and hit rate — why you need dozens of ads per winnerPaid social for apps is a volume game — one operator saw 1 winner per ~85 videos and ~$800k of $1.5–1.8M spend wasted; teams now ship 400+ concepts/month, test in cheap geos, and treat flat, "stable" performance as a sign they stopped searching for breakout creatives.
- Dark patterns in web quiz funnels — where the line is and why it's closingThe "black-hat" end of web2app — $1 plans followed by pre-checked add-ons that charged ~$350–400, per-day prices hiding the full price, refund walls — why regulators and payment providers are clamping down, and practical guardrails for honest funnels.
- International expansion — which markets, localization depth and local pricingLocalization as a growth lever in 2026 — start where you have an edge, use cheap similar-converting geos, price with a purchasing-power index (Simply's "Big Mac index" lifted ARPA), localize consistently end to end, and expect culture-specific surprises (Simply's Japan paywall; Replika's failed Japan bet).
- Is my app ready for Meta ads? Funnel benchmarks and the 7-point checklistSteve P. Young's 7 checks before spending on Meta ads for an app — funnel conversion targets (5–10% install→trial, 30%+ trial→paid, ~2% install→paid), proof strangers pay, LTV, tracking, research, concepts, budget.
- Is paid acquisition incremental? Organic ceilings, cannibalization and geo holdoutsOrganic-heavy apps (Replika, Solid Starts) eventually saturate their niche and find that new paid spend often cannibalizes organic; Simply measures this with geo holdouts (switch app or web campaigns off per country) and aims for "enough truth" in CAC models, not perfect attribution.
- Lead ads with the product's "magic moment" (often an AI feature)Features that make people react — PhotoRoom's AI background removal, Simply Draw bringing a child's drawing to life, Cal AI's photo-to-calories, Pingo's AI roasting pronunciation — make the best ad hooks, cut CAC and can unlock markets that never worked with paid ads.
- Paid social creative testing for apps — levers, hook/hold rate, 3-day testsThe levers of paid social (Meta/TikTok/YouTube) for apps, hook-rate and hold-rate targets, and Ivy's 3-day creative test (4 creatives per themed ad set, $50/ad set) run on highest-converting weekdays.
- Test demand with ads before building the app (pre-sell)Yuliya Lennox's rule — before vibe-coding an app, run marketing that sells a PDF, concept or promise (refunding if needed) to learn audience size, acquisition cost and willingness to pay; plus why founders must do early marketing themselves.
- Tripwire offers instead of free trials in web2appWhy web funnels replace free trials with tiny paid entry offers ($0.99–$10 intro periods or one-time boosts) that renew or upsell to full price, how to size them, and examples (Audible, Hily, Coursiv, Headway).
- Ugly ads — why unpolished, shocking creatives win (and when brand matters)Yuliya Lennox's "make ugly ads" case — pattern-break the pretty feed, say what the product does in the first second, lead with the pain — plus the rare cases (trust-sensitive brands like Solid Starts) where an off-brand ad backfires.
- Using AI to scale app ad creatives (without fake testimonials)Where AI helps app ad production in 2026 — permutations of real-human ads (ElevenLabs voice/translation, Suno music), AI statics, LLM-brainstormed extreme hooks, Veo 3 / Higgsfield video — and why fully synthetic "testimonials" carry FTC and backlash risk.
