The primary relationship owner for every client we have:

We are hiring a Customer Success Manager at Throxy: someone who will manage a portfolio of accounts, ensuring every client gets maximum value from our SDR teams and outbound sales engine. Your mission is simple - grow revenue, retain clients, and make every stakeholder feel like Throxy is the best decision they ever made.

This role sits at the intersection of sales, operations, and relationship management. You will work closely with our Growth, Product, and Operations teams to translate client needs into action, whether refining a campaign, escalating an issue, or proactively identifying an upsell opportunity.

North Star KPIs

Client retention, net revenue retention (NRR), and CSAT. We want clients to stay, expand, and refer others. The best signal that you're doing your job well is that clients actively choose to grow with us.

High ownership. No passengers:

Founder-level agency

There is no bureaucracy here. If you see a problem, you fix it. If you have a better idea, you say so. We expect everyone to operate like a founder, not an employee waiting to be told what to do.

📊

Data-driven, not data-obsessed

Numbers matter, but so does judgment. We care about doing the right thing for clients even when the spreadsheet doesn't tell you to. Direct communication, real accountability.

🤖

Genuinely AI-native

We are excited about what AI makes possible. If you find a new tool on Monday and have it in your workflow by Friday, you will fit right in. We adopt fast and we expect the same.

🚀

Fast, early, important

YC-backed, early stage, with real clients and real revenue. Your work directly shapes how the company operates at a moment where every decision compounds.

The best stack. No compromises:

Our primary platform is Throxy.com - our internal super app where operations, client data, and campaign management all live in one place. Beyond that, we are deeply AI-native: we move fast, adopt the best tools available, and expect everyone on the team to do the same. From Claude to Raycast to Fathom, we are always looking for technology that removes friction and raises the bar on what's possible.

What you will own:

01
Client Portfolio Management

Own a book of accounts end-to-end, from onboarding through renewal and expansion. You are the single point of contact for your clients and responsible for their long-term health.

02
Revenue Growth

Identify and execute upsell and cross-sell opportunities within your portfolio. Partner with the Growth team to surface expansion opportunities at the right moment in the client lifecycle.

03
Stakeholder Management

Build deep relationships across multiple levels of each client organisation, from day-to-day contacts to executive sponsors. Understand each stakeholder's priorities and communicate accordingly.

04
Campaign Optimisation

Work with our Operations and SDR teams to continuously improve campaign performance. Translate client feedback into actionable briefs and hold teams accountable to outcomes.

05
Proactive Communication

Don't wait for clients to come to you. Send regular performance updates, flag risks early, and celebrate wins. Make every client feel informed, valued, and confident in Throxy's ability to deliver.

What success looks like:

Full audit of your client portfolio completed with a clear view of health, risk, and opportunity across every account.

Every client has had a structured onboarding or re-engagement conversation with clear goals and success metrics defined.

At least one upsell or expansion opportunity identified and progressed within your portfolio.

Client satisfaction scores trending upward and churn risk materially reduced across your book.

Deeply embedded in Throxy's operational rhythm and acting as a reliable bridge between clients and internal teams.

More to be defined together as you learn the role and the business.

What we're building towards:

Automated Client Health Scoring

A real-time dashboard surfacing at-risk accounts before they churn, giving you early warning signals and recommended actions so you can intervene proactively.

Personalised QBR Templates

Auto-generated quarterly business review decks pre-populated with client-specific campaign data, so you spend your time on insight rather than pulling numbers together.

Expansion Playbooks

Structured, data-driven frameworks that identify the right moment and the right pitch to expand a client's engagement with Throxy, turning instinct into a repeatable system.

Highly valued for this role:

01
Multi-tasking

Managing several accounts at once without losing quality or dropping context on any of them.

02
Organisational Skills

Keeping tasks, timelines, and client commitments structured and visible across a busy portfolio.

03
Communication

Clear, confident communicator across all levels. Additional languages are a meaningful plus.

04
Growth / CS Experience

Prior exposure to outbound sales, account management, or customer success in a commercial environment.

What we are looking for:

  1. 012+ years in Customer Success, Account Management, or a client-facing commercial role
  2. 02Proven ability to manage a large portfolio simultaneously without dropping the ball on any account
  3. 03Exceptional stakeholder management, comfortable navigating complex organisations at every level
  4. 04High agency and ownership mindset: you identify the problem and go fix it
  5. 05Strong commercial instinct with the ability to identify and close expansion opportunities
  6. 06Outstanding written and verbal communication, always appropriate for the audience
  7. 07Comfortable in a fast-paced, high-growth environment where priorities shift and ambiguity is the norm
  8. 08Curiosity and openness to using AI tools to improve your own output and efficiency
