Compass is a marketing mix model built on Google Meridian and tuned for B2B sales cycles. See where your next dollar creates the most pipeline — with a number you can defend to your CFO.
B2B SaaS marketing leaders are stuck between attribution dashboards that can't see anything but the last click, and enterprise MMM engagements priced for Fortune 500 brands. Neither fits a company with a six-month sales cycle and $2–10M in annual paid spend.
By the time pipeline turns to revenue, the original marketing touch is far outside the attribution window. Last-touch and multi-touch dashboards systematically under-credit the channels — events, podcasts, brand — that warm the deal in the first place.
Off-the-shelf marketing mix models assume an 8-week attention span and a DTC channel mix. They literally have no way to model field events, SDR outbound, or the way a LinkedIn ad in March still influences a deal that closes in September.
CFOs don't want a number. They want a number with confidence around it. The Excel models marketing teams use to defend budget can't express "ROI between 2.4× and 3.8× with 90% probability" — so the conversation defaults to "trust me."
Compass fits a Bayesian hierarchical model with Hill saturation and 26-week geometric adstock on top of Google Meridian. Every channel gets a posterior response curve, not a point estimate — so you can see exactly where each channel is under-invested, healthy, or past the knee.
Compass runs Meridian's Budget Optimizer on the fitted posterior and returns the budget reallocation that maximizes incremental pipeline subject to per-channel floors and ceilings. You don't get a recommendation pulled from a spreadsheet — you get one backed by thousands of posterior draws.
Every per-channel ROI lands with a 90% credible interval. Every recommendation comes with a posterior distribution. Compass's analyst console shows the full math behind every number — so when finance asks "how sure are you?", you have a real answer.
No SaaS sign-up, no integrations to wire. For our first five design partners, getting started is two days of CSV prep on your end and a Meridian fit on ours.
Weekly paid spend per channel, weekly pipeline created, and a few simple controls. Six quarters of history minimum — most CRMs export this in under an hour.
Compass runs a Bayesian hierarchical fit with B2B-tuned adstock (26-week memory). Four chains, full convergence diagnostics, sensitivity analysis on every channel.
A 30-minute screen-share readout of the channel-by-channel response curves, the optimizer's recommendation, and the one-page brief you can take straight to your CFO.
Google Meridian is the open-source Bayesian marketing mix modeling library Google uses internally for media measurement. It handles Hill saturation, adstock, hierarchical pooling across geos, calibration with experimental priors, and full posterior uncertainty quantification.
Compass wraps Meridian with a B2B-tuned channel registry (paid search, LinkedIn, field events, podcast, content syndication, SDR outbound), a longer 26-week adstock for sales-cycle memory, and a pipeline-created KPI in place of closed-won revenue. The math underneath is exactly what Google publishes — we just shape the inputs and outputs so a B2B SaaS CMO can actually use it.
Compass is in design-partner mode. The product engine is real, the math is published, but the SaaS layer — automated integrations, self-serve onboarding, multi-user dashboards — is on the roadmap, not in the box. For our first five design partners, getting started is hands-on and high-touch. In return, you get steep pricing and direct input on what we build next.
For Compass we recommend at least 18 months — ideally 24 — of weekly data with reasonably consistent channel mix. That's roughly what Meridian needs to identify Hill curves and adstock decays separately for each channel. If your channel mix changed dramatically inside that window (a brand new motion, a paused channel), we'll surface that as identifiability uncertainty in the response curves rather than pretend the model is more confident than it is.
Recast is an excellent product — they pioneered modern MMM for digital-native brands. Their core focus is DTC and consumer brands, and their pricing reflects the enterprise contracts they sign. Compass is positioned for B2B SaaS specifically: pipeline-created as the KPI instead of revenue, 26-week adstock for long sales cycles, and field events / SDR outbound as first-class channels. If you're an omnichannel DTC brand, Recast is probably the better fit. If you're a Series B-D B2B SaaS company, we're built for you.
Same answer with a slightly different shape: Prescient's core focus is DTC and omnichannel consumer brands, and they're excellent at it. Their case studies, integrations, and pricing all reflect that ICP. Compass is wedged into B2B SaaS — a vertical no modern MMM platform is seriously chasing yet.
Two ways. First, the dependent variable is weekly pipeline value created — opportunities generated, not deals closed. Pipeline sits 1–4 weeks after a marketing touch instead of 3–9 months, which gives the model enough signal to fit. Second, adstock max_lag is set to 26 weeks (vs. 8 in a default DTC model), so a LinkedIn ad seen in March can still be credited for a deal that closes in September.
One row per week, with columns for: week-starting-Monday, weekly pipeline value created (the KPI), weekly spend per paid channel, and a few simple controls (price index, holiday flag, competitor index). Most B2B SaaS companies can export this from Salesforce + their ad platforms in under two hours. The full schema is available on request — email tobijek@gmail.com and we'll send it.
The math engine is Meridian, full stop — we don't try to out-Google Google on Bayesian inference. What Compass adds is the B2B SaaS configuration layer (channel registry, adstock tuning, KPI shift to pipeline), the executive surface (sliders, recommendation banner, what-if forecasts) for non-technical CMOs, and the analyst console for the people who actually have to defend the numbers. We're upfront about this in the footer of every UI.
We're not publishing public pricing yet — partly because we want design partners to influence it, partly because the right price for a $50M ARR Series C is different from a $200M ARR Series D. For comparison, Recast and Prescient are typically in the high-five-figure to low-six-figure ARR range for B2B SaaS scale. We expect to come in materially below that for design partners and modestly below it for general availability, but the exact number depends on what we build in the next six months.
