Founding Sales & Account Executive ( AI / B2B SaaS) – Aesthetic Medicine

Startup (AI / B2B SaaS)
Freelance - Fully Remote (ESP based)
Full-time preferred
Equity opportunity for long-term fit

About River AI
Our mission is to redefine how modern brands grow in the era of AI.
Founded in 2025 in Switzerland & Spain by a Forbes 30 Under 30 Entrepreneur and an Ex-Silicon Valley AI-Engineer, River is building AI-native growth & lead infrastructure for modern businesses.

We're an early-stage startup with a live product and our first paying customers in aesthetic medicine & plastic surgery. So far, sales has largely been founder-led.

Now we're looking for the person who can help turn that into a repeatable sales engine.
Not someone to create slides about Go-to-Market. Someone who actually sells.

Your Opportunity
You won't be joining an established sales organization.
You'll shape it.

This is our first dedicated sales hire and one of the most important roles in the company.
You own the pipeline end to end: You find the clinics, you pick up the phone, you run the demo, you follow up, you close — and you bring what you hear in the market straight back to the founders.
You'll work directly with the founders and become one of the people closest to our customers and market.

If you're excited about joining early, taking real ownership and potentially growing into a commercial leadership role as River scales, this could be for you.

What You'll Do - (90% Hands on, 10% Strategic)

Own the full sales cycle: prospecting → first call → demo → follow-up → close
Build pipeline across aesthetic clinics & plastic surgeons, initially Spain and Europe
You are not too proud for anything: Cold calls, 6th follow-ups, manual research, sending the voice note on a Friday evening, whatever gets the clinic to answer
Run discovery calls, product demos, negotiations and closing




Build genuine relationships with clinic owners, doctors and industry leaders
Use modern sales automation intelligently, while being perfectly comfortable doing things manually
You understand technology and can explain an AI product without hiding behind buzzwords
Keep your pipeline structured and know exactly where every opportunity stands
Identify objections, buying signals and patterns in the market
Show up where the industry is: congresses, clinic groups, industry communities, partner networks
Bring customer feedback directly into Product and work closely with the founders
Help us refine our pitch, positioning, ICP and sales playbook based on insights
Ultimately: turn conversations into customers and customers into revenue

You'll be measured primarily on pipeline, conversions and customers won – not how busy your calendar looks.

Your Profile

You have proven hands-on B2B sales experience
You've personally done outbound sales, including cold calling and demos
You're comfortable owning the entire sales process , not just one step of it
You know how to create opportunities instead of waiting for inbound leads
You can show us what you've sold and ideally some numbers behind it
You're highly communicative and good at building trust quickly
You're persistent and understand that great sales often happen in the follow-up
You're commercially sharp and comfortable selling technology
You're proactive, entrepreneurial and highly self-driven
You thrive in a fast-moving startup where not everything has a playbook yet




You care about outcomes rather than titles, hierarchy or looking busy
You're fluent in Spanish and English
French, German or Italian is a plus

Strong Advantage if:

You already understand or have a network in aesthetic medicine, plastic surgery, private healthcare, medical SaaS or adjacent industries.
Early-stage startup experience or SaaS experience is another strong plus.

 This Role is probably not for you if...

You want to build a team before you've closed the first deals yourself
You call yourself a "Go-to-Market" person but haven't dialed a number in two years
You don't like cold calling
You expect an SDR to fill your calendar
You need a finished playbook before you can perform
You think outbound means launching an automated sequence and waiting
You're looking for the structure and predictability of a large company

We're early.
We need a builder who sells, not a manager waiting for something to manage.

What we offer

A key role in an early-stage AI startup with paying customers already live
Direct access to the founders, product and customers
Fully remote within Spain
Freelance collaboration to start, with the opportunity to transition into a long-term full-time role.
Full-time preferred, although we're open to exceptional part-time profiles
Competitive freelance compensation with performance-based upside
Real ownership, responsibility and influence
Potential equity opportunity for exceptional long-term fit
Opportunity to grow into a broader commercial leadership role as River scales
Exposure to cutting-edge AI technology
The chance to help build a category-defining company from the very beginning
