Now open to early adopters

Cut cloud waste. Not your speed.

KÖLTTÖ connects to OCI and AWS to surface hidden overspend and rank the optimizations that matter — in one portal. Azure, GCP, Linode, and DigitalOcean are next.

Your cloud bill,
finally explained

Connect a cloud. See spend, inventory, and ranked savings in the portal — without living in the provider console.

Always-on cost monitoring

KÖLTTÖ syncs billing and inventory so you can watch spend trends, services, and resources in one place — not after the invoice lands.

Ranked savings recommendations

Idle compute, unused storage, oversized shapes — opportunities are ranked by estimated impact so you know what to fix first.

Spend analytics

Slice cost by service, account, and region. See where money went this month — and how it compares to last.

Multi-cloud, starting now

See OCI and AWS spend in one portal, with a provider filter on the dashboard. Azure, GCP, Linode, and DigitalOcean use the same model when they ship.

Budgets & month-end forecast

Set spend caps and get alerted as usage approaches the limit. The dashboard projects month-end so you can act before the bill.

Inventory & exports

See what you are running, with utilization context for rightsizing. Export cost data as CSV.

Connect, sync,
then cut waste

Private beta is a portal for OCI and AWS: connect a cloud, sync spend and inventory, then work ranked opportunities. The AI preview below is what’s next.

KÖLTTÖ AI — preview Coming soon
Why did our EC2 bill jump 40% last week?
I found the culprit. Your data-pipeline-prod cluster scaled from 8 to 24 instances on April 14th at 3:22 AM — triggered by a spike in queue depth that never resolved.

The autoscaling group didn't scale back down because your scale-in cooldown is set to 2 hours and utilization stayed at 12%.

Fixing the cooldown and rightsizing to 12 instances would save ~$2,840/mo.
Show me all services we could rightsize
Found 17 services with rightsize opportunities totaling $12,440/mo . Top 3 by impact:

1. rds-analytics — db.r6g.4xl → db.r6g.2xl -$3,100
2. eks-staging — reduce node count 18→8 -$2,200
3. elasticache-prod — cache.r6g.2xl → cache.r6g.xl -$1,840

Explore, then act

Use dashboards, spend analytics, budgets, and inventory in the portal. Plain-English Q&A and a guided planner are on the roadmap.

Koltto AI next

Coming next — not in beta yet

These are planned. They are not available in private beta today. We’d rather show them here than sell them as live.

Soon

Koltto AI

Ask cost questions in plain English, or chat about spend in the portal. The bot and analyzer are next — not in private beta today.

Soon

Forecaster

A dedicated view of where the month and quarter are heading — beyond the dashboard’s month-end projection.

Soon

More clouds

Same connect → sync model. Azure and GCP next, then Linode and DigitalOcean — all in the same portal.

Soon

Optimization planner

Turn ranked opportunities into an implementation plan. No one-click remediations in the portal yet.
