Optimal Workshop''s Starter plan costs $199/month billed annually — $2,388 a year — and includes unlimited seats, unlimited participant responses, and every study type the platform offers. It also limits you to five launched studies per year and two live studies at a time. That is $477.60 per study, and the limit that matters is not how many people you employ or how many participants answer. It is how many separate questions you are allowed to ask.
According to Vendr''s buyer data, the median Optimal Workshop buyer actually pays $10,873 per year, with contracts ranging from $5,500 to $15,350. That is roughly 4.6x the published Starter price — the clearest possible signal that most teams blow through five studies and start buying bundles.
Quick answer: what Optimal Workshop costs in 2026
| Plan | Price | Seats | Studies | Responses |
|---|---|---|---|---|
| Free plan | Discontinued | — | — | — |
| 7-day trial | $0 | Up to 9 invitees | All tools except Optimal Interviews | Results from 2 participants only |
| Starter | $199/mo billed annually ($2,388/yr) | Unlimited | 5 launched/year, 2 live at a time | Unlimited per study |
| Enterprise | Custom | Unlimited | Custom study bundles | Unlimited per study |
| Participant recruitment | Add-on | — | — | 1 credit per participant (standard) |
Two things in that table catch teams out. There is no free plan any more — the trial lasts seven days, shows you results from only two participants, and you lose access to your account and your study results when it expires unless you upgrade. And the Starter plan is widely misreported by software directories as "$199 per user per month." It is not. Optimal Workshop''s own pricing page lists unlimited seats. The per-user framing is a third-party error, and it makes the platform look far more expensive than it is for large teams — while hiding the constraint that actually bites.
The meter nobody defines: what counts as a "study"
Here is the single most important thing to understand before you sign, and it is genuinely not documented anywhere public.
Optimal Workshop sells you five launched studies per year. Nowhere on the pricing page, and nowhere in the help centre article comparing paid subscription plans, does the company define what a study is. There is no published answer to the obvious follow-up questions:
- Does a card sort and a tree test count as one study or two?
- Does relaunching a study after fixing a broken task consume another one?
- Does a pilot with five colleagues count the same as a 300-participant study?
- What happens when you hit five in month seven?
The help centre article on plan differences states the Starter limit as "5 launched studies / year" and the Enterprise limit as a "custom number of studies launched / year," and goes no further. For a plan whose entire value depends on that one number, the absence is remarkable. You are being asked to budget against an undefined unit.
The chaining trap
The platform''s own documentation answers the question indirectly, and the answer is expensive.
Optimal Workshop supports chaining studies — sending a participant from one straight into the next. Its help centre explains that to do this "you will require you to use the Redirect URL setting in tree testing, card sorting, first-click testing, prototype testing or surveys," and confirms that "the results of chained studies cannot be merged, and will remain separate in your Workspace."
Separate results means separate studies. So a perfectly ordinary information-architecture project — an open card sort to learn how users group your content, a tree test to validate the navigation you designed from it, and a short survey to capture reasoning — is three of your five annual studies, consumed by one piece of work.
Do that twice and your year is over in March. At $477.60 a study, that single IA project costs $1,432.80 of your allowance.
The two-live-studies concurrency cap is a second, independent constraint stacked on top. Even if you have annual launches left, you cannot run a card sort, a tree test, and a first-click test in parallel across three different product squads. One team waits.
What teams actually pay
The published price is the floor, not the bill. Vendr''s anonymised contract data puts the median Optimal Workshop contract at $10,873 per year, in a range of $5,500 to $15,350.
| What you see | What the median buyer pays |
|---|---|
| $2,388/yr (Starter list) | $10,873/yr |
| 5 studies/year | Custom study bundles |
| — | 4.6x the list price |
Vendr''s documented negotiation outcomes are worth knowing before a renewal call:
- One buyer negotiated an additional 14% discount by leveraging budget constraints, competition, and credible churn risk.
- Another secured 20% off a new purchase.
- One team reduced its user count to three and saved 34% versus upgrading to Enterprise — which is a striking outcome on a plan that advertises unlimited seats, and suggests the sales motion prices differently from the website.

The recruitment add-on
Participants are separate. Optimal Workshop sells recruitment on a pay-as-you-go basis or through credit bundles, at 1 credit per participant for standard recruitment; managed recruitment is quoted per project.
This is the same structural pattern we found at Lyssna, where panel access is metered in credits on top of the subscription, and at User Interviews, where the advertised $49 session fee turns out to be roughly 22% of the true B2B cost once incentives and targeting are added. Whenever a research platform separates "the software" from "the people," budget for both. Our user research cost calculator walks through the full stack.
Who Optimal Workshop is genuinely good for
Credit where it is due. Optimal Workshop remains the most established toolkit for information architecture work specifically. If your research year is a small number of large, well-planned IA studies — a navigation redesign, a taxonomy overhaul, a content audit — then five studies a year may be exactly right, unlimited responses is generous, and the unlimited-seats policy means the whole design team can look at results without a per-head charge. For that shape of work it is a good buy.
It is a poor fit for the opposite shape: continuous discovery, where you want to ask a small question every week. The pricing model is explicitly designed to discourage that. Every question has a marginal cost of one-fifth of your annual allowance, which is precisely the incentive you do not want if you are trying to build a research habit. Teams comparing options across that category will find our roundup of card sorting tools and the wider user research tool pricing breakdown useful.
The alternative: stop paying per question
The deeper problem with a study-metered plan is that it prices curiosity. Every time someone on your team says "I wonder why users do that," the honest answer under a five-study cap is "not this quarter."
Koji is built the other way round. There is no study limit at all — you run as many as you want. Pricing is credit-based and tied to conversations that actually produce something:
| Optimal Workshop Starter | Koji Interviews | |
|---|---|---|
| Annual price | $2,388 (billed annually) | €79/month (€790/yr, 2 months free) |
| Studies per year | 5 | Unlimited |
| Concurrent studies | 2 | Unlimited |
| Seats | Unlimited | Unlimited |
| Method | Card sort, tree test, first-click, survey | AI-moderated voice and text interviews with follow-up probing |
| Analysis | AI-powered analytics on closed tasks | Automatic thematic analysis + one-click reports |
| Free tier | None (7-day trial, 2 participants) | 10 free credits, no card |
Koji''s Interviews plan is €79/month for 79 credits. A voice interview costs 3 credits, a text conversation 1, and a report refresh 5 — so €79 buys roughly 26 AI-moderated voice interviews a month, every month, across as many separate studies as you like. Critically, only conversations scoring 3 or higher on quality consume credits: a participant who abandons after ten seconds does not bill you. Compare that with a study meter, where a study that produced nothing still cost you 20% of your year.
Koji also does the thing an IA tool structurally cannot. Card sorts and tree tests tell you what people clicked; they cannot tell you why a label confused someone. Koji runs AI-moderated interviews that follow up in the moment — asking "what did you expect to find under that heading?" when a participant hesitates — and combines them with six structured question types: open_ended, scale, single_choice, multiple_choice, ranking, and yes_no. You get the quantitative pattern and the reasoning behind it in the same session, with themes surfaced automatically rather than tagged by hand.
Legacy IA platforms were designed when a study was a project you scheduled a quarter in advance. That assumption is baked into their pricing. Research demand has moved on: teams now need answers in hours, not quarters, and a plan that rations questions is a plan that guarantees you ship on guesswork for nine months of the year.
Frequently Asked Questions
How much does Optimal Workshop cost in 2026?
The Starter plan is $199 per month billed annually — $2,388 per year. It includes unlimited seats, unlimited participant responses per study, and all study types, but caps you at five launched studies per year and two live studies at once. Enterprise pricing is custom and includes larger study bundles. Vendr contract data puts the median actual spend at $10,873 per year.
Does Optimal Workshop still have a free plan?
No. The free plan has been discontinued. Optimal Workshop now offers a 7-day free trial that gives access to all tools except Optimal Interviews and lets you invite up to nine team members, but you can only view results from two participants — and you lose access to your account and any study results when the trial ends unless you upgrade.
What counts as one "study" on the Starter plan?
Optimal Workshop does not publicly define this, on either its pricing page or its help centre plan-comparison article. What the documentation does confirm is that chained studies remain separate and their results cannot be merged — so a card sort, a tree test, and a follow-up survey in one project consume three of your five annual launches. Get the definition in writing from sales before you sign.
Is Optimal Workshop priced per user?
No, despite what several software directories claim. Optimal Workshop''s own pricing page lists unlimited seats on both Starter and Enterprise. The meter is on launched studies, not people. Interestingly, Vendr records one buyer who reduced their user count to three and saved 34% versus an Enterprise upgrade, which suggests seat counts still influence negotiated quotes even though the website says unlimited.
How much does participant recruitment cost on Optimal Workshop?
Recruitment is a separate add-on, sold pay-as-you-go or in credit bundles, at 1 credit per participant for standard recruitment. Managed recruitment is priced per project depending on your targeting requirements. Participant incentives are a further cost on top.
What is the best Optimal Workshop alternative for continuous research?
If your bottleneck is the five-study cap rather than IA features, Koji is the direct answer: unlimited studies, no concurrency limit, and €79/month for 79 credits — about 26 AI-moderated voice interviews. Where Optimal Workshop tells you what users clicked, Koji''s AI interviewer asks why in the moment and returns automatic thematic analysis. You can start free with 10 credits, no card required.
Run research without a study counter
Optimal Workshop is a capable IA toolkit with a pricing model built for a slower era — one where five questions a year was a reasonable research budget. If that matches your work, it is a fair deal at $2,388, provided you pin down what a "study" means before signing and budget for the 4.6x gap between list and median contract.
If it does not — if your team wants to ask a question this week and get an answer tomorrow — the study meter is the wrong shape entirely.
Try Koji free and get 10 credits, no credit card. Launch unlimited studies, run AI-moderated voice interviews that probe like a skilled researcher, and get themes and a shareable report automatically — from question to insight in hours, not quarters.
