Koji is an AI-native customer research platform built in Amsterdam. Our AI interviewer runs hundreds of natural, in-depth conversations at scale, replacing both shallow surveys and slow one-on-one interviews. Teams use Koji to go from a research question to actionable insights in hours, not weeks.

Is Koji related to the Japanese koji fungus or fermentation?

No. Koji (koji.so) is a B2B software-as-a-service company that provides an AI customer research platform. The Japanese kōji (kōji-kin / Aspergillus oryzae) is an unrelated fermentation culture used in sake, miso, and soy sauce production. Despite the shared name, the two are not connected.

Is Koji the same as withkoji.com or koji.com?

No. withkoji.com was a link-in-bio creator platform that was acquired by Linktree in 2024 and is no longer active. Koji at koji.so is a separate, unrelated AI-native customer research platform for product, research, and growth teams.

Koji was founded in 2024 by Nirmay Panchal and Luca Lago, and is operated by Koji Research Inc.

Koji is headquartered in Amsterdam, the Netherlands. All customer data is stored in the EU and the platform is GDPR-compliant. Koji never uses customer interview data to train AI models.

Koji conducts AI-moderated voice and chat interviews with your customers at scale, automatically transcribes them, and synthesizes themes, sentiment, and key quotes into shareable research reports. It's used by product managers, UX researchers, founders, and customer success teams to understand the why behind customer behavior.

Enterprise Customer Experience, Q3

Walk me through the biggest friction point or frustration your team hit during the rollout.

Mapping admin permissions onto our SSO groups took far longer than we planned for.

That is useful, thank you. Thinking about the rollout overall, how satisfied has your team been with the experience this quarter? You can see the scale on your screen.

A nine is high, so the fundamentals are clearly working. What would need to change to move that closer to a ten?

What did we learn?

Enterprise teams are sold on the outcome but stall in setup. Mapping permissions onto existing SSO groups is the biggest rollout blocker (11 participants, 26%), typically adding two to three weeks before a team can invite anyone. Once live, day-to-day satisfaction is strong (29 participants, 69%).

HIGH-IMPACT FINDING

Permission mapping is the rollout bottleneck

Mapping admin roles onto existing SSO groups added two to three weeks before launch
Teams without a dedicated IT contact stalled longest, often pausing rollout entirely
Accounts with IT support cleared the same step in days

HIGH-IMPACT FINDING

Satisfaction climbs sharply once teams are past setup

Day-to-day satisfaction averaged 8.6 of 10 for teams live more than a quarter
Teams still onboarding averaged 5.9, a gap driven by setup rather than the product
Steady-state users described the core workflow as the part that just works

NOTABLE PATTERN

Renewal risk concentrates in single-champion accounts

Accounts relying on one internal advocate reported the weakest expansion plans
Champion turnover left teams unsure who owned the relationship

From the follow-ups

Teams rate the product highly once live, but the follow-ups show the score is held back by setup friction and unclear internal ownership rather than the product itself.

Setup dominates the gap: Teams scoring below 7 almost all pointed to permission mapping rather than anything about the product.4
Ownership after go-live: Several accounts described losing momentum when their champion moved on, with no clear successor.3
What would make it a 10: Respondents consistently asked for a guided permissions path during onboarding.5

Computation details

Drawn from 11 interviews the analysis identified as supporting this claim.

Supporting interviews (11)

#3“We had to get IT to remap every admin group before a single person could log in. That was three weeks on its own.”

#5“Our identity team had a two week queue, so the group mapping just sat in their backlog.”

#8“The product was fine. Getting our SSO groups to line up with the roles was the part that dragged.”

#11“We underestimated it completely. Lining up roles with our identity provider took the whole first sprint.”

#14“Honestly if we'd had someone from IT in the kickoff we'd have been live in a week instead of a month.”

#19“Nobody owned it internally once our champion moved teams, so the permissions work just sat there.”

#21“Every role we added meant another round trip with security. That is where the three weeks went.”

#27“Setup was the only painful bit. Once people were in, adoption took care of itself.”

#29“The mapping itself was not hard. Waiting for approval to touch the directory was.”

#33“We paused the rollout twice waiting on directory access. Not the tool's fault, but it was the blocker.”

#38“If I did it again I would start the SSO work before signing, not after.”
