Who should a startup hire to run a design sprint?
Choose a design sprint partner by the decision you need to make, the prototype you need tested, and who carries the result into a build.
A design sprint is worth hiring out when one product decision is stuck and you can put a prototype in front of target customers within the week. Who to hire depends on what happens after Friday. Some firms facilitate and stop there. Others carry the result into a build. A few spend most of the week testing what the founders believe about their customers.
Humbleteam publishes this page and is one of the seven firms compared. The firms appear in alphabetical order. This is our reading of each firm’s public pages as of October 9, 2026. There are no paid placements, rankings or scores.
How we chose the firms
Every firm, Humbleteam included, had to pass four tests:
- It runs sprints for client teams: a time-boxed engagement that ends with a prototype or other artifact tested with users or buyers. Courses, certification and facilitator training do not count.
- A startup can buy it. The firm does not limit its sprints to large organizations.
- It publishes a specific format (days or weeks, and what you receive) or a named sprint example.
- It is a firm with clients, not a solo practitioner or a software tool.
Several names that come up often in sprint searches did not pass on their current pages. AJ&Smart’s site now leads with facilitation training, and we found no sprint offer for client teams. Voltage Control leads with AI transformation and facilitator certification. Design Sprint Academy facilitates sprints but says it runs only high-stakes ones and adapted the method for large organizations. Designing Insights says it is not accepting new consulting projects. LEANSTUDIO’s validation sprint is an online course. Many facilitators sell sprints as individuals, which is a different purchase from hiring a firm. Their public pages do not show a sprint you can buy.
| Firm | Based in | Sprint on offer | Public example |
|---|---|---|---|
| Basis | Ontario, Canada | Four-week Accelerator Sprint ending in a prototype tested with customers | ShowStop |
| Design Sprint Ltd | Lausanne, Switzerland | Five-day GV sprint, two-day Foundation Sprint, 30-day MVP route | TeraWatt Infrastructure, Yuh |
| DesignMap | San Francisco | Vision Sprint (two weeks to a quarter), Market Validation Sprint | Cisco Meraki |
| Empatic UX | Innsbruck, Austria | One-week design sprint with remote participants | Monkee |
| Humbleteam | Prague and Dubai | Three- to five-day sprints | ING Amsterdam banking MVP |
| thoughtbot | Boston | Shaping Sprint over several weeks | Joydrive, Health Match 360 |
| Wily | Charlotte, North Carolina | Four-day sprint, two-hour Decision Sprint | AvidXchange testimonial |
A public example gives you something to ask about. It does not tell you who would join your sprint or when they are free.
Basis
Basis is run by two co-founders and sells research and validation to funded startups. Its Accelerator Sprint takes four weeks and ends with a high-fidelity prototype tested with customers Basis recruits. In the ShowStop case, an AI creative platform used a five-day sprint to test a rebuilt second version before writing production code. Basis reports that the prototype and the customer feedback fed the founders’ fundraising conversations.
It suits a team with paying users and a specific doubt about the next version. Ask how much of the week the founders must attend and who moderates the sessions.
Design Sprint Ltd
Design Sprint Ltd was founded in Lausanne in 2015 and says it has run more than 150 sprint weeks. It sells the five-day GV sprint, a two-day Foundation Sprint for earlier questions, and iteration sprints. Its MVP-in-30-days route adds a first week of workshops with its team and three weeks of build by a low-code partner, Olympe. Case studies include TeraWatt Infrastructure, a San Francisco company building charging for electric truck fleets, which had a first product version three months after its sprint, and the Swiss neobank Yuh.
It fits a founder who wants the classic method from a facilitator with a long record. Ask who recruits test users in your market and whether the low-code route suits your stack. It also sells sprint training, a separate purchase.
DesignMap
DesignMap is a San Francisco firm of three senior partners. Its Vision Sprint runs from two weeks to a quarter and produces a working prototype of a product’s next direction that leaders react to. Its Market Validation Sprint is scoped to one launch decision and tests whether real buyers will commit. Its site describes a Cisco Meraki project in which design sprints aligned more than 50 stakeholders.
DesignMap suits a product that already has users and leaders who disagree about direction. It is a less natural fit for a founder without a product yet. Ask whether the Vision Sprint includes sessions with end users, because its description centers on leadership reviewing the prototype.
Empatic UX
Empatic UX is a UX research and design firm in Innsbruck, Austria, working since 2016. In its Monkee case, a finance-app startup ran a week-long design sprint with remote participants. The team interviewed the target group, built prototypes, tested them with users and reached a validated MVP concept. Empatic reports that Monkee then released the app. Its German-language service page says it often works with start-ups and smaller companies.
It suits an early product, especially in Europe, that needs research as much as facilitation. Ask how it recruits and tests in your market and language.
Humbleteam
Humbleteam works from Prague and Dubai. Its public work page lists a three-day sprint with a US MedTech supplier on compliant hospital products, a five-day design sprint to reinvent a top Arab bank’s mobile app with AI, and a B2B banking MVP with ING Amsterdam taken from zero to a tested product in 5 days. It also lists workshops teaching founders at 11+ startup accelerators how to validate product hypotheses. The ING result describes one engagement. It is not a standard duration.
Humbleteam passes the four tests, but on thinner evidence than some firms here. The sprints appear as portfolio cards, with no standalone sprint page, and the three sprint cards come from a bank, a MedTech supplier and ING, not from startups. It suits a sprint that should lead into broader product and brand design, especially in finance or health. Ask for a comparable startup question, the assigned team and the design scope after the sprint. The portfolio shows the cards.
thoughtbot
thoughtbot is based in Boston and works remotely. Its Shaping Sprint has five phases: understand, diverge, converge, prototype and test. It runs over several weeks. The artifact can be a clickable prototype, a proof of concept, a roadmap document or an ad experiment, tested with users, stakeholders or technical constraints. For Joydrive, an online car-buying startup, thoughtbot ran a design sprint to validate the business model, then built the MVP in six weeks. It also ran a pro bono sprint for the founders of Health Match 360, with interviews on an interactive prototype.
It fits a team that expects the same firm to build afterward. Ask whether the sprint can be bought without the build, and whether your artifact will be tested with users or only reviewed.
Wily
Wily is based in Charlotte, North Carolina, and says it runs and teaches sprints full time. Its Design Sprint takes four days. If your whole team cannot commit, Wily builds and tests the prototype on days three and four with one or two of your people. It also offers a two-hour Decision Sprint as a cheaper first step. Its site carries a recommendation from Jake Knapp, who created the method, and a testimonial from an AvidXchange director.
Wily’s stated clients lean toward Fortune 500 teams, with start-ups mentioned briefly. Ask for startup references.
How to choose
Start from the decision, then from what follows the sprint.
- If you doubt who the customer is or what they value, look at Basis or the Foundation Sprint at Design Sprint Ltd.
- If a live product has stakeholders who disagree, look at DesignMap or Wily.
- If the result must turn into software soon, look at thoughtbot or the 30-day route at Design Sprint Ltd.
- If the product is regulated and design work will continue, Humbleteam is a candidate.
The original GV design sprint is a five-day method: map on Monday, sketch on Tuesday, decide on Wednesday, prototype on Thursday, test on Friday. An agency engagement may add preparation and follow-up around it. Jake Knapp and John Zeratsky’s introduction to the Foundation Sprint in Lenny’s Newsletter describes a two-day format for earlier questions. Ask each candidate which belief your sprint could disprove.
Agree on a short decision brief before the first workshop: the decision, the target participant, the behavior you need to see and the evidence that would reject the idea. After the sprint you should hold the prototype, the test approach, the findings and a recommendation to proceed, revise or stop. You should also get a list of open product and engineering questions, with an owner for each.
A small qualitative test can expose usability problems. It cannot show a market-wide conversion lift or predict fundraising. If your need is wider than one question, the comparison of design agencies for startups covers full redesign work. For a fixed release date, the 8-week launch guide separates prototype approval from delivery.
