Conjointly offers a lightweight, DIY approach to conjoint analysis — reasonably priced, friendly onboarding, and a template-driven study builder aimed at non-specialists. If you need a quick-and-dirty read on three attributes and have a few hundred respondents, it does the job. Ordeen is built for the harder tier: production-grade decisions where the methodology has to withstand scrutiny from a quant audience.
The positioning difference
Conjointly targets marketers who want conjoint output without a methodology deep dive. Templates, guided flow, standard outputs.
Ordeen targets insights managers and pricing specialists who need the full statistical apparatus — and auditable methodology to defend recommendations to a CFO or a CPO who asks “how do we know this is right?”.
Where Ordeen beats Conjointly
Statistical sophistication — Ordeen ships full Hierarchical Bayesian estimation with NUTS, non-centred parameterisation, LKJ priors and MCMC convergence diagnostics. Conjointly uses simpler estimators by default; HB is available but less deeply exposed.
Latent class segmentation — BIC-selected $K$, posterior membership probabilities, segment-level simulators. Conjointly offers basic segmentation; not comparable depth.
Krinsky-Robb WTP — Ordeen computes posterior-draw credible intervals and refuses degenerate ratios. Conjointly tends to report point WTP without uncertainty bands.
BH-corrected interaction testing — with Haldane small-cell correction. Conjointly does not expose multiplicity-corrected interaction grids.
ACBC rigour — Ordeen estimates per-respondent likelihood on the exact alternatives actually shown (correct for adaptive designs). Conjointly supports ACBC but less transparent about the estimation strategy.
Methodology published — Ordeen’s full statistical specification is public. Conjointly’s is partially documented.
Where Conjointly beats Ordeen
Lower starting price — Conjointly offers a free tier and pay-as-you-go for small studies. Ordeen is £2,500/month flat — overkill if you run one study a quarter.
Simpler for novices — if the research team has never done conjoint before, Conjointly’s template flow is easier onboarding.
Specific features we don’t have — Conjointly supports some study types (TURF Insight, Monadic Testing) that are either less deep in Ordeen or not present yet.
When to use which
Use Conjointly if: you run choice modelling occasionally, your decisions are low-stakes, your audience doesn’t ask hard methodology questions, and your sample sizes are small (under 150 respondents).
Use Ordeen if: you run choice modelling regularly, your decisions are consequential (pricing a flagship product, cutting a feature from a roadmap, redesigning a portfolio), your audience includes quant-literate reviewers (CFO, CRO, head of pricing, consulting partner), or you need the live simulator for client sharing.
Pricing comparison
Conjointly starts at $75/month for small studies and scales up based on respondents and complexity; serious work typically lands in the $500–$2,000/study range. Ordeen is £2,500/month flat with unlimited studies, unlimited seats, and transparent respondent packs. For teams running 2+ studies per quarter, Ordeen is cheaper AND more rigorous.
