Company
Why we built VendAce
It started with a founder who needed to sell - and refused to practise by burning real demand. Infinite Arc AI built VendAce so practice could finally match how people improve.
The short version
Built because the founder needed better practice.
Not a side project bolted onto a chatbot. A learning product for people who sell - starting from a real constraint: you cannot burn finite leads just to get good.
A founder is the first salesperson
Nathan Salter Perez was building as an entrepreneur. He already knew the founding team had to sell - and that he did not have unlimited time for weak practice.
No spare demand
Real leads are finite. Practising on live prospects is an expensive way to learn.
No time for theatre
Less-than-efficient methods burn hours. Founders need practice that actually raises skill.
Engineering. Elite teaching. Machine learning.
Years as a software engineer. Years in education - most recently Deputy Head of Mathematics at Eton College. Fresh depth in ML. And a tech moment where realistic spoken conversation practice finally became possible.
Software
Years shipping hard systems - not slides about AI.
Teaching
How people actually improve - from top institutions, not vibes.
The moment
Voice and conversation AI got good enough to rehearse for real.
The long view was clear: anyone who sells can benefit. No one has maxed out their ability - skill keeps improving - and that is true across industries, not one vertical.
Companies. Founders. Learners. Us.
VendAce was never only for one buyer type. Individual improvement first - with company access when teams need it.
Companies
Reps who need real practice at scale - without managers inventing the curriculum.
Fellow founders
Selling the thing you built - without wasting the only leads that matter.
Students & early career
School, university, first sales roles - practise before the stakes are brutal.
Infinite Arc itself
We sell too. The product had to be something we would trust for our own craft.
Base design is B2C: your account, your progress, your own time - like serious language learning. B2B sits on top so companies can still get reps practising when motivation is uneven.
18 months of proving it
Customer feedback. Hard iterations. One objective that never moved: actually help people learn - not ship a toy that feels impressive for a week.
How the product changed - coaching, skills, modes, engagement, the algorithm - is its own story. That is where you see the decisions that made VendAce a learning system.
