Hey everyone 
I’m the solo founder of SteadyStake, an automated DCA crypto savings app built on Base. MVP is done and we’re getting ready for mainnet. I’m looking for 1–2 early team members: 
Marketing / Growth (Web3, community, content, GTM) 
Partnerships / Account Manager (DeFi & ecosystem deals) Comp is equity + revenue share (no salary, early stage). If you’re someone who wants real ownership and to help build from the ground up, feel free to DM me 

Growth Manager
Why work at Higgsfield AI?
🧩 Higgsfield AI is one of the fastest-growing GenAI startups in the world — top-1 globally by growth, #1 Video AI in the U.S.
Our users already include Elon Musk, Madonna, Snoop Dogg, and Will Smith. In just 8 weeks we shipped 12 releases, reached 11M users and generated over 1.2B social impressions.
We just raised $50M Series A to scale even faster. This is your chance to join early — when the team is still small but strong — and make your mark on the next GenAI decacorn.
What Growth Means at Higgsfield
At Higgsfield, growth is about distribution and revenue, not branding or theory.
A Growth Manager here is a high-agency operator who:
Finds and unlocks scalable distribution channels
Moves fast with imperfect data
Automates anything repeatable
Negotiates deals that compound over time
Takes full ownership of outcomes
This is a hands-on execution role. You will build, test, break, fix, and scale.
What You Will Do
Creator & Partner Growth
Source, evaluate, and onboard creators who can drive high-quality users
Build and negotiate creator partnerships (affiliate, revenue share, performance-based deals)
Run creator campaigns end-to-end: outreach → deal → launch → optimization
Build long-term relationships with creators, not one-off placements
 
Prioritize volume with intent — not spam
Important:
You are not managing Higgsfield’s own YouTube or social channels.
Your job is growth through external creators and their audiences.
YouTube Growth (Primary Focus)
Own YouTube as a distribution channel through creator collaborations
Drive traffic and usage via creator-generated content
Measure success by output and impact, not vanity metrics
Primary KPI:
Number of new unique creator videos generated per month
Analytics & Decision-Making
Build simple but effective models in Excel / Google Sheets
Estimate traffic, conversions, and revenue impact
Decide which creators, formats, and deals to scale or cut
Turn messy, incomplete data into clear execution decisions
Automation & Scale
Automate creator discovery, outreach, tracking, and reporting.
Build lightweight systems using tools like Sheets, Zapier, Apify, Instantly, CRMs, APIs, or scripts.
Reduce manual work and increase throughput.
Execution & Experimentation
Run fast experiments across platforms (YouTube, TikTok, Instagram, X).
Test formats, incentives, and deal structures.
Learn quickly and iterate.
There is no separation between “creative” and “technical.” One person owns the full cycle.
Who We’re Looking For
We’re looking for smart, high-energy— not perfect resumes.
You should have:
Strong English (spoken and written)
Strong communication and persuasion skills
Comfort working with numbers, spreadsheets, and assumptions
Ability to work independently without hand-holding
High agency, ownership mindset, and bias toward action
Emotional intelligence and confidence in negotiations
Willingness to operate in a fast-paced, high-intensity environment
Russian is required. English is required.
Backgrounds that often do well:
Growth, partnerships, or business development
Sales or performance-driven marketing
Early startup operators or founders
Engineering or computer science backgrounds
Consulting, analytics, or finance with strong execution bias
A technical background is a plus, not a requirement.
Level & Compensation
- All hires join formally at a junior level, regardless of prior experience
- Starting compensation is competitive and paid in USD
- Exceptional candidates with standout B2C or founding-level growth experience may be considered individually
Onboarding & Expectations
Onboarding lasts ~1 week
You receive a playbook and immediate ownership
Very little babysitting — autonomy is expected
From week two, you are expected to operate independently
This role requires high energy, fast thinking, and resilience.
Work Format
On-site only (Almaty office)
No remote or hybrid setup
Full immersion into the team and product is essential
 
This Role Is NOT a Fit If You:
Prefer strategy over execution
Avoid spreadsheets, metrics, or accountability
Need detailed step-by-step instructions
Are uncomfortable negotiating or pushing back
Expect predictable hours or a 9–5 schedule
Prefer low-intensity environments
Working Hours
This is a high-intensity role with a non-standard schedule.
Workdays: Monday–Saturday (6 days per week)
The working day is aligned with global creators and partners and includes late hours - from 2 pm till 2 am Almaty time.
Expect a high workload and a fast execution pace
This role is best suited for candidates who:
Are comfortable working evenings and nights
Can sustain focus in a high-output environment
Are motivated by speed, ownership, and impact rather than fixed hours
This is not a 9–5 role, and the schedule should be considered carefully before applying.
Relocation & Office Setup
This is a fully on-site role based in Almaty, Kazakhstan.
Remote or hybrid work is not available
Candidates must be willing to relocate and work from the office full-time
The company provides relocation support, including:
Assistance with travel to Almaty
Support during the initial relocation period
Help with legal and administrative setup as needed
Relocation is considered an integral part of the role, as close in-office collaboration is essential for speed, learning, and impact.
What We Offer
Full-time role. Please note: we will not consider candidates planning to combine this role with other jobs.
On-site role in Almaty office. 
Long-term growth opportunity — we are looking for candidates interested in learning, growing, and building with the team. A minimum 1.5+ year commitment is expected.
