Yesology is a small, senior practice that helps product, marketing, sales, customer success and ops teams redesign how yes happens in their organisation.
We help teams make yes easier.
Because right now, somewhere in your organisation, yes is getting lost.
Inside a pricing fight.
Inside fifteen versions of the value story.
Inside a renewal call that turns into a therapy session on budget.
And everyone is exhausted.
We fix that by redesigning how yes actually happens across your team.
Using behavioural science, consumer psychology, choice architecture and a solid dose of connected thinking.
So more of the right customers try, buy, stay and expand…
with less friction, less drama and fewer midnight Slack messages.
For leaders in product, marketing, sales, customer success and ops in SaaS, B2B, B2C and subscription businesses.
If your team touches a customer’s decision, this is for you.
A short call that usually leaves people saying “oh wow ok that explains everything”.
Why we built Yesology
Before Yesology, we were both running behavioural consultancies. Working across financial services, SaaS, big tech, digital products, governments.
Lauren was deep in psychology and strategy, helping teams understand how people actually decide. And teaching behavioural design at different universities.
Hannah was fixing messy launches, fuzzy pricing, and marketing that didn’t land.
Different consultancies. Same storyline every time:
Pricing was a political debate, not a designed system.
Teams told different stories and customers felt the wobble.
Trials, deals and renewals relied on individual heroics.
Decisions were powered by opinion, not evidence.
Everyone was sprinting.
Nobody was fixing the system underneath the sprinting.
So we built Yesology to do exactly that:
re-architecting the structure behind yes.
Who doesn't want stronger foundations, and walls, and detailing?
We call that structure your Yes Architecture:
how you price
how you tell the story
how the journey feels
how renewal and expansion decisions get made
When those pieces click, yes gets easier.
For customers. For teams. For you.


What makes Yesology different
We only work on customer yes
We don't do marketing side quests.
No “while you’re here, can you fix our culture too?”
Just the customer journey from interest to yes to yes again.
We're talking both the people who set it and the people who live it every day.
You work directly with seniors who know what they’re doing
No partner pitch then mystery handover to five juniors called Ben.
The people you meet are the ones doing the work.
We fix structure before design
You cannot decorate your way out of confusion.
We fix the system so everything downstream works properly.
We measure success in behaviour
Less discounting.
Cleaner decisions.
Shorter sales cycles.
Renewals without dread.
If you want a rebrand without touching how decisions get made, we are not your people.
If you want yes to be designed on purpose, we probably are.
Inside most organisations there are two levels of yes.
We work with both.
People who set the yes.
People who deliver the yes.
Who sets the yes
These are your decision makers around pricing, proposition and growth.
Typically:
founders with a team, C level and senior leaders
heads of product, marketing, sales, customer success and ops
commercial, revenue, pricing and RevOps leads
They decide things like pricing, offers, how value is framed, and what counts as success in the numbers.
Who delivers the yes
The people who deliver the yes are the ones who live with those decisions every day.
Typically:
designers and product teams working on journeys and conversion
marketing and communication teams
sales teams, account executives and SDRs
customer success, onboarding and implementation teams
support, lifecycle marketing and growth teams
They are the ones turning strategy into real conversations, real journeys and real renewals.
We design the work so both levels are in the same picture.
That means:
leaders are not making yes decisions in a vacuum
frontline teams help shape the strategies they are asked to deliver
getting a yes is easier as teams use the most effective behavioural strategies.
the tools we leave behind work in leadership meetings and in real customer moments
It is one of the reasons the work sticks.

Is Yesology right for you?
You are in the right place if:
You lead product, marketing, sales, CS, growth or ops
Your team is involved in pricing, adoption or renewal
You suspect yes is happening by accident
You want change in weeks
You need a behavioural edge to get things done
Probably not a fit if:
You want 'not behaviour focused' sales or presentation training
You want a tweak instead of real change
We will tell you quickly if we are not the right move.
And will recommend someone else instead.
How we help you

How we think about yes
Content is not decoration. It is how decisions get made. People do not say yes to information. They say yes to systems that lead them to yes. Teams create more yes when they connect up thinking. The fastest wins come from reframing what you already have. If it does not change behaviour in the real world, it is not finished. Yes should always be ethical, even if that means saying no.
