Frequently Asked Questions

Why Bear Lumen

How is Bear Lumen different from FinOps tools like Mavvrik or CloudHealth?

FinOps tools track cloud infrastructure spend at the resource level (VMs, storage, GPU hours). Bear Lumen goes further: we reconcile AI costs with revenue data, produce margin reports by customer and feature, and tell you when pricing needs to change. A FinOps tool shows your total OpenAI spend. We tell you that Customer X on Feature Y is underwater, and recommend what to adjust.

How is Bear Lumen different from Stripe, Metronome, or Orb?

Billing tools handle the transaction. Bear Lumen handles what they don't: reconciling provider costs with revenue, producing margin reports by customer, feature, and model, and letting you model pricing changes with a simulator. Keep your billing system. We plug into it and do the cost-and-margin analysis.

Who is Bear Lumen built for?

Teams that need to see AI cost and margin clearly. If you build AI products, Bear Lumen produces margin reports by customer and feature, flags underwater accounts, and lets you model pricing changes before you make them. If you use AI internally, it produces per-team cost reports and tracks spend against your budgets.

What's the core problem Bear Lumen solves?

Nobody can see AI cost and margin clearly. Provider invoices land, spreadsheets get updated quarterly (if at all), and by the time you've pieced it together the window to act has closed. Bear Lumen does that work: it reconciles costs with revenue continuously, attributes every dollar to a customer, feature, and model, and lets you model changes before you make them.

Why not use a spreadsheet?

Spreadsheets work until they don't. Manually reconciling provider invoices, Stripe data, and usage logs takes days per month and makes scenario modeling painful. Bear Lumen does that reconciliation continuously and gives you a simulator for the scenario modeling. You get the report, not the spreadsheet.

Do I need paying customers to use Bear Lumen?

No. Cost tracking works from day one with no customers or billing required. When revenue flows, the same data powers margin analysis and pricing validation.

Product

How does cost attribution work?

The SDK captures request metadata (customer ID, feature, model) alongside cost data. We aggregate provider costs and attribute them to individual requests, then produce margin reports by customer, feature, and model.

Do I need to replace my existing billing system?

No. Bear Lumen plugs into your existing billing system (Stripe, Orb, etc.) to get the revenue side. We connect that with provider cost data and handle the margin analysis, reporting, and recommendations. Nothing changes about how you invoice.

What pricing models does the system support?

Flat rate, volume pricing, tiered/graduated pricing, and hybrid (base fee + usage). The pricing scenario modeling lets you model any combination against historical usage data.

How long does integration take?

Adding the SDK to your codebase takes minutes. Full setup (connecting revenue sources, defining dimensions) depends on your stack. First pricing decisions typically arrive within the first week. Early customers get direct onboarding support.

Can I test with sample data first?

Yes. The platform includes demo data so you can see how cost attribution, margin analysis, and pricing recommendations work before connecting your own providers and revenue sources.

Does the SDK add latency to your live LLM queries?

No. The SDK reads the response your provider already returned, so nothing sits between you and the model. Tracking events queue in memory and flush in background batches, the same pattern analytics SDKs have used for years.

Security & Pricing

What data is collected and how is it secured?

We collect request metadata and cost data. All data is encrypted in transit (TLS 1.3) and at rest (AES-256). No raw prompts or customer PII. You own your data and can export or delete it anytime. Building toward SOC 2 Type II certification.

How does pricing work?

Bear Lumen offers a free Developer plan with 10K events per month. Growth ($49/mo) includes 250K events and Scale ($199/mo) includes 2M events. Usage beyond your plan limit is billed per event at your plan’s overage rate. Enterprise pricing is custom. See the pricing page for the full breakdown.

What if I only have a few customers?

The system works at any scale. Smaller customer bases mean faster integration and clearer data. Many teams find it easier to establish cost tracking early.

What exactly counts as a billed event?

A billed event is a single tracked AI call you send through the SDK or API: one chat completion, one embedding request, one tool call. We read the token counts, model, cost, and the metadata you attach. Your monthly limit counts these events, not tokens, and we never store raw prompts or completions.

Do you support self-hosted or custom models?

Yes, on Enterprise plans. Self-hosted and custom models are supported alongside dedicated ingestion queues, a data processing agreement (DPA), multi-year retention, and a custom SLA. Talk to the founder and we will shape a plan around your stack.
