Organic growth built Strava. Paid performance can help take it further.

Strava's community, shared activity, partner ecosystem, and word of mouth are real strengths. But relying too heavily on organic growth and walled gardens can make the next phase harder as CPMs rise and competition increases. Moloco complements what is already working by helping Strava reach incremental users across premium independent app inventory and optimize toward conversion, not clicks.

Accelerate new user acquisition

Find buyers who do more than install

The goal is not simply to add more users. It is to find people most likely to register, purchase, return, and become valuable members of the Whatnot community.

Optimize for buyer value

Use machine learning built for app outcomes to find users likely to take the actions that matter after the install.

Enter new markets with premium inventory

Use a single partner to access premium global inventory and apply learnings across geographies.

Go beyond the walled gardens

Reach high-value buyers across millions of independent apps where they already spend time.

Scale with greater control

Get publisher-level transparency, brand-safety controls, and fraud protection without giving up performance.

Re-engage and invest in lapsed users

Give lapsed buyers a reason to come back

New categories can create fresh reasons to return. Moloco helps Whatnot directly reach the lapsed buyers most likely to respond, so reactivation does not depend on category expansion alone.

Reconnect with proven buyers

Reach people who already know Whatnot and have shown intent, then prioritize those most likely to return and purchase.

Optimize beyond the reopen

Build campaigns around meaningful downstream actions, not just getting someone back into the app.

Match the message to the moment

Use category, promotion, and marketplace moments to make the reason to return more relevant.

Match the message to the moment

Acquire new buyers while creating a coordinated path to bring valuable usersback over time.

CTV that performs

Provable performance with Moloco’s CTV

Whatnot has already explored CTV. Moloco can help turn it into an accountable growth channel.

‍

Household-level bidding

Bid smarter across every screen in the house, with the same precision you expect from mobile.

Premium inventory

Show up next to the shows people actually watch, not just wherever there’s space.

MMP attribution

Track every impression back to a real install or in-app event, no black boxes hindering performance.

Ghost-bidding incrementality

Prove CTV is actually driving lift, tested against a real control group, not a guess.

Stay independent as live commerce consolidates

Whatnot’s strength comes from building a differentiated marketplace and community. Moloco helps extend that independence to growth by reaching users outside the platforms that increasingly compete for the same buyers, sellers, and commerce activity.

Independent reach

Expand beyond a small group of platforms and access a broader open-internet audience.

Transparent performance

See where budget runs and evaluate results against the same outcomes your growth team already uses.

Technology built to learn

Turn campaign signals into better decisions as Whatnot enters new markets and attracts new buyer segments.

A partner that can scale globally

Keep the operating model simple as the number of markets, categories, and audiences grows.

Built for teams that want to prove performance

Outcome-first machine learning

Independent measurement
