The first AI that learns from your ad data. Not flattened feature tables

Every basis point of ad targeting accuracy translates directly to revenue. Traditional ML makes it worse by flattening relational data into feature tables, destroying the signals that actually predict click-through, conversion, and attribution. KumoRFM learns directly from the relationships in your data and is pre-trained on tens of thousands of datasets, delivering higher accuracy than any internally-built model, in hours, not months.

Why ad tech companies choose Kumo

Target precisely, attribute accurately, optimize bids in real time

Here's how Kumo transforms ad tech with relational AI.

5.4x

Better conversion prediction

KumoRFM learns from the full advertiser-publisher-user-impression-conversion graph. It captures cross-device journeys, frequency effects, and creative-audience interactions that flat click models miss.

30%

Lower cost per acquisition

Pre-trained on thousands of relational schemas, KumoRFM understands behavioral patterns across impression, click, and conversion data. Better targeting means fewer wasted impressions and more efficient spend.

Minutes

To deploy new targeting models

CTR prediction, bid optimization, audience segmentation, attribution modeling, campaign forecasting. One platform replaces the custom pipeline you'd otherwise build for each model.

One platform, every prediction

9 use cases, one platform

From click-through rate prediction to viewability forecasting, KumoRFM powers every ad tech prediction from the same connected data. no per-model pipelines, no feature engineering.

Click-through rate prediction

Predict CTR with dramatically higher accuracy by learning from the full graph of user behavior, ad creative attributes, placement context, and historical conversion patterns — not hand-engineered feature tables.

Explore →

Bid optimization

Optimize real-time bidding by modeling the relationships between audience segments, inventory quality, competitive dynamics, and conversion likelihood in a single relational graph.

Explore →

Audience segmentation

Build richer audience segments by learning from the full relational structure of user behavior, content affinity, purchase signals, and cross-device activity — not just demographic buckets.

Explore →

Attribution modeling

Move beyond last-click attribution by modeling the full graph of touchpoints, channels, and conversion paths — capturing the true multi-touch relationships that drive conversions.

Explore →

Ad creative optimization

Predict which creative elements will resonate with specific audience segments by learning from the relational patterns between creative attributes, user preferences, and engagement outcomes.

Explore →

Frequency capping

Optimize impression frequency per user by modeling the relationship between exposure count, engagement decay, and conversion probability across channels and time windows.

Lookalike audience building

Build higher-converting lookalike audiences by leveraging relational signals — shared behaviors, content affinities, and network connections — instead of surface-level demographic matching.

Campaign budget allocation

Allocate budgets across campaigns, channels, and audiences by predicting marginal returns from the full graph of historical performance, audience overlap, and competitive dynamics.

Viewability prediction

Predict ad viewability before bidding by modeling the relationships between placement context, page structure, user scroll behavior, and device characteristics in real time.

The ad data advantage

Your impression data already encodes the signals that predict clicks, optimize bids, and maximize ROAS.

Even with a world-class data science team, feature engineering fundamentally caps your accuracy. The moment you flatten relational tables into feature vectors, you discard the nuanced relationships between impressions, clicks, conversions, audiences, campaigns, creatives, and publishers. This isn't a team quality problem — it's a structural limitation of traditional ML that no amount of hiring solves.

KumoRFM is pre-trained on thousands of relational schemas. It has already learned what conversion, click-through, and attribution patterns look like across hundreds of data structures — the same advantage GPT has over custom NLP. Your team cannot replicate this breadth no matter how much time you give them. Foundation model scale changes the game.

KumoRFM doesn't replace your data science team — it 10x's them. They go from shipping 3–5 models per year to 50+ per quarter. Tedious feature engineering disappears; the interesting work — defining predictions, interpreting results, driving business impact — remains.

One platform powers CTR prediction, bid optimization, attribution, audience segmentation, and every other ad tech prediction — from the same connected data.
