The alternatives

Five alternatives, sorted by fit.

Fieldstream is a Stockholm-based AI marketing platform for iGaming operators, with causal MMM, player lifetime value, affiliate analysis and geo lift testing. These five take a different route. The best-for lines say which one suits you.

  1. Odins

    Managed Bayesian platform That's us

    Best Fieldstream alternative for advertisers who want one model for the total budget, offline media included.

    Odins is a managed marketing investment platform. Fieldstream goes deep on iGaming, with player value and affiliates at the center. Odins is built for the budget decision in any industry: one Bayesian model per market, with TV, radio, OOH and print next to digital, pricing and promotions. Priors are set with your team, data flows in daily, and scenarios and forecasts are yours to run any time. The model is retrained monthly and checked against stored forecasts, and a person reviews every recommendation. Disclosure: this is our platform.

  2. Lifesight

    Unified measurement

    Best for global retail, DTC and travel brands that want unified measurement with agent execution.

    Causal MMM, geo-based incrementality testing and attribution in one product, with AI agents that can push changes to the ad platforms within guardrails. Lifesight does not state its inference method publicly. Pricing on request.

  3. Google Meridian

    Open-source framework

    Best open-source option for teams with data scientists and geo-level data.

    Google's Bayesian framework, the most packaged of the open three, with the strongest budget optimizer and native geo-level modeling. You build and maintain everything yourself, and a 2026 academic review flags the default uniform priors as a misuse risk. Free license, paid for in staff and time.

  4. Recast

    Advanced specialist

    Best for large, mostly US advertisers with analytics teams and daily data.

    A Bayesian MMM with time-varying parameters, weekly automated refreshes and out-of-sample backtesting. Built for Fortune 500 and large DTC budgets, with enterprise pricing that is not published.

  5. Funnel Measure

    Data platform

    Best for teams that want measurement on top of the data hub they already run.

    Stockholm's marketing data hub, with MMM, attribution and incrementality layered on its own data foundation and updated daily. The three methods cross-check each other instead of sitting in one model. Deepest across digital sources.

When to look elsewhere

Four reasons to look for a Fieldstream alternative.

Fieldstream brings industry depth few measurement vendors have: NGR, player value, affiliates and geo tests built for regulated markets. These are the situations where another route fits better.

  • You are outside iGaming, or your marketing questions reach beyond player value and affiliates
  • The first question is the total marketing budget, before any single channel
  • You want a Bayesian model with priors set with your own team and written down
  • You have data scientists in-house and want an open framework you fully control
Why Odins

One budget model, checked at every retrain.

Odins is MMM, run for you: the data work, the priors, the model and a reviewed recommendation, with scenarios and forecasts open to your team any time.

  • One Bayesian model per market, with TV, radio, OOH and print next to digital, pricing and promotions
  • Priors set in 2 to 3 working sessions, from your spend history, digital saturation signals and structured interviews
  • Results from lift and geo tests you have run are taken into the model, and a structured test is proposed when a channel is uncertain
  • Data flows in daily and the model is retrained monthly, with forecasts stored before actuals arrive and checked at each retrain
  • Scenarios and forecasts you run yourself any time, in the platform or from Claude via the Odins MCP

A tight range is a decision. A wide range is a test plan, with cost boundaries.

FAQ

Frequently asked questions.

What is the best alternative to Fieldstream?

It depends on your industry and on who should run the model. For one model of the total marketing budget across online and offline media, run for you, Odins is the alternative we would point to, and yes, it is ours. For unified measurement with geo tests and agent execution, Lifesight. For building in-house with geo-level data, Google Meridian. For large advertisers with daily data, Recast. For measurement on top of a data hub, Funnel Measure.

How is Odins different from Fieldstream?

Fieldstream is built for iGaming operators, with NGR, player lifetime value, affiliate analysis and geo lift testing in one platform. Odins is built for the budget decision across industries: one Bayesian model per market with offline media and business drivers inside it, priors set with your team, data flowing in daily, a monthly retrain checked against stored forecasts and a person behind every recommendation. The full comparison, with sources, is on Odins vs Fieldstream.

Is there an open-source alternative to Fieldstream?

Yes. Google Meridian is a free Bayesian framework with native geo-level modeling, and PyMC-Marketing and Meta Robyn are other open options. Your own team builds and maintains the model, so the cost is staff and time.

Do we need geo tests to use a marketing mix model?

No, but they help. With Odins, results from geo and lift tests you have run are taken into the model. Where the data cannot resolve a channel, the reviewed recommendation proposes a structured test, often a pulse test, and says what the test is expected to cost.

What does a Fieldstream alternative cost?

Fieldstream does not publish pricing on its own site; its TapClicks marketplace listing offers a free first month. Lifesight and Recast do not publish pricing either, and Meridian is free to license and paid for in staff and time. Odins is a subscription priced for the budget it optimizes, for companies with a marketing budget from EUR 1M to several hundred million a year, with the team included and no data science hires needed.
