For founding teams
Startups are messy. Humfrid makes your journey less messy by identifying and continuously testing your hypotheses, so you learn faster and ship what people want.
Built by teams from




Assumptions
Write down who you believe the customer is. Humfrid tests that hypothesis against what buyers actually say, across every conversation, and shows when the evidence tells you what to pursue next.
Customer conversations, and who was in them, captured against the hypothesis you are testing.
Each conversation lands on the hypothesis it tests. The reasons to pursue it, and the reasons not to, build up on their own.
See why to pursue it, and why not, with the sources attached, right where the team works.
Decision log
Humfrid keeps track of the decisions you make and why you made them, to keep you accountable and always learning what works, and what doesn't.
Humfrid picks the decision up from Slack and the tools, the moment it is made. The log stays current on its own.
The metric, the message, or the interview stays with the assumption. The next person sees why the moment they need it.
Slack, analytics, tickets, and interviews are already attached to the decision.
Each assumption keeps the one it replaced, with the date. You can see what you believed, and the next test starts from there.
Work that contradicts the assumption is flagged the day it starts. The team can stop it before the week is spent building it.
Conflicts with work in flight
Keep one step. Tighten step 1.
Proactive
The same pain shows up across conversations, a metric moves, two people build from different beliefs. Humfrid tells the person who can act, the same day.
Activation slipped 4pp overnight, mostly on step 1 of the new onboarding tour. @maya that's your flow.
Heads up: @sam is putting a paywall on the flow @priya just made free. I booked you both a 20-min sync today at 2:30.
@priya the checkout rewrite grew from 8 to 13 tickets: the payment provider can't do partial refunds. Moving refunds to v2 keeps the June date.
@priya Thursday's launch is at risk. The shorter tour still isn't in, and step 1 is the open question.
@dana the pricing test was committed for this week. It's still in review, and the squad is on the refactor.

@Humfrid are we on track with our priorities?
Not fully. 2 of 4 priorities are on track1. The other two:
Calendar + Humfrid
Walk into every conversation with what you already know, what you need to learn next and the questions you need to ask.
Northstar at 11. You’re already caught up.
They’ve asked for SSO three times, and it’s on the enterprise goal. The export fix they flagged shipped last night, so you can lead with that.
Usage is down this week. Worth asking how the rollout feels on their side.
A good question: is SSO the thing in the way, or is it further down the list?
Discovery at 3. The goal on the table is activation.
What we know from customers: the first screen is unclear, and two people this week stopped before the tour finished. Nobody in those calls asked for a second step.
The decision for the room is whether to shorten step 1, or talk to a few more people before changing it.
Standup in 15 minutes. Here’s a place to start.
Step 1 is down 4pp since yesterday. The shorter tour merged last night, which is the likely place to look.
Maya has been waiting on the paywall tickets since yesterday. A yes or no there would unblock her.
Opening there gives her an answer she’s been waiting on.
Retro at 4, on the shorter onboarding tour.
What happened: it shipped two days ago. You kept one step and tightened the first screen. A second step had been in the plan for a week before that.
What worked: this week’s interviews said the first screen is clearer, and two people finished who had stopped before.
What didn’t: step 1 is still short of the activation goal, and the tour went out before the team had a shared read on what success looked like.

See and edit everything Humfrid knows. Your data stays in your workspace and is never used to train a model.
Humfrid understands more than Claude even though it has access to less context. Previously I had to prompt Claude 5 times to get an answer that makes sense. Humfrid just gets it.
I’d pay $500 out of my own pocket just for the meeting prep. I’m always in back to back meetings and Humfrid helps me through my weeks.
I’ve been using Humfrid recently and loving it. Tools like this are the future - not just for product teams, but for organizations at any size.
This is what I wish I’d had my whole career.
FAQ
Humfrid is built for the small team shipping the product. He holds the assumption, the evidence behind it, and the next step for each person, and he keeps that team on the same bet.
Share the assumption you are testing and the documents around it, and connect the tools the work already lives in. He starts in Slack.
Your data stays yours. It is never used to train AI models or sold, and you can export it and delete your workspace at any time.
Humfrid helps founders find traction from what the data, customers and market are already saying.
