Real Results: How Catalyx Supports our Clients

See how Catalyx has helped founders with anything ranging from fundraising to growth.

$100M+ Series D: Financial forecast, department buildout, and tactical plan

A well capitalized start-up was seeking a Series D to build out a new department. We created their financial forecasts, headcount plan, and tactical plan. The company used our outputs to raise a $100M+ Series D.

$10M in Venture Debt: Seed Stage

As an operator at this start-up, received two $5M term sheets. Created and presented the financial forecasts and pitch materials.

<$1M Convertible Notes: Pre-Seed

For a company with a highly complex technical product, created the financial forecasts, pitch materials, and met with select investors.

Team Effectiveness & Org Design for a newly acquired Unicorn ($1B+)

A department within a newly acquired company was facing high employee churn as they struggled to scale output. After surveys, interviews, and workshops we identified key issues and designed a new organizational design. Employee churn improved >50%.

New Department Buildout

A growing late-stage start-up was seeking guidance on how to build out a new department, the associated costs, and the tactical plan. Following our guidance, the team was able to scale to the next stage of fundraising.

3-Year Growth Plan for a F50

As the VP of Revenue Growth at Citi, served as the analytical lead segmenting customer cohorts and creating company-wide growth targets. This body of work gained C-Suite and board of director approval.

Growth Targets for 30M+ Customers

As the VP of Revenue Growth at Citi, led target setting and forecasts for tens of millions of customers. These numbers were approved at the C-Suite and Board level.

$0 to $6M Annualized for a seed-stage start-up

As an operator and the Head of Growth, I helped find PMF, built a team of 10, and scaled growth directly through strategy + execution.

Testimonials

Ari played a pivotal role in leading the investment process for my third company. He built our forecasting model and pitch deck entirely from scratch, providing invaluable insights and thoughtful suggestions that drove the business forward. Beyond the numbers, Ari had a significant impact on our journey to achieve product-market fit. He’s proactive, dependable, and thrives in ambiguity, quickly earning the trust and respect of his peers through his dedication and exceptional results.

Jeremy Greenberg
Founder
Crowdwave

I am an engineer turned founder that knows nothing about growth strategies and marketing. Ari and his team are invaluable in their analysis of my startup from an investors perspective and in the guidance they give for growth. Instead of being lost and fumbling my way towards growth, Ari has given me strategies and advice that saves me time and money in growing my company. Highly recommend them!

Kevin Jordan
Founder
Actimate

Ari was great to work with and delivered above my expectations, both in terms of quality and speed. He was highly analytical and able to break down my market sizing problem clearly and articulate his findings, even though there wasn't much high-quality data. His findings and recommendations were very helpful and gave me great insight.

Joyce Z
Founder
Stealth Start-up

The two biggest things about Ari is that he can think and create solutions on his own, his logic is sound (but he has a process to adjust it where it isn't), and his work is very thorough.

Brett Nowak
Founder
Liquid & Grit

l've had the pleasure of working with Ari Eng for several years across multiple strategy projects. His expertise, strategic insights, and ability to execute at a high level consistently impressed me. He's been instrumental in delivering value, navigating complex challenges, and aligning with goals to drive meaningful outcomes. I highly recommend Ari and his team for any organization looking for top-tier consulting support.
