Without Lava

  • No clear view into compute costs

    You’re flying blind - hard to know what’s driving usage or how to price it.

  • Wasted engineering time

    Your team spends weeks building and maintaining custom billing systems.

  • Slower time to monetization

    Every delay in launching paygo pricing is lost revenue and fewer insights.

  • Hard to scale or change pricing

    Adjusting tiers, discounts, or usage metrics requires constant dev work.

  • Risk and complexity managing payments

    Handling funds, compliance, and infrastructure distracts from your core product.

    Understand what’s driving costs - then turn it into revenue.
