Our story


What’s the scoop?

Whilst at college, Rob works in an Ice Cream truck and Rich is putting together cars at the Ford Automobile plant. The best stories have unlikely beginnings, right?


Networking, works.

Rob and Rich meet at a LIBOR networking event. No not that LIBOR, the Little Investment Bankers of Rutgers. Cute.

2002 & 2003

Making Momma proud

Rich follows in Rob’s footsteps and graduates from Rutgers. Rob lands him a job at his roommate’s bank. Told you networking worked.

Since the dawn of time

Seriously, how much?

Just like everyone else in the history of finance, Rob uses Bloomberg and Factset every day. And every day, he wonders how such an outdated tool can cost $25k a year.


Flying solo

Rob leaves his job and has to pay for resources for the first time. He realizes the gulf that exists between retail tools and pro-grade tools. An idea begins to form.


Exploring the idea

Rob does a little digging and starts to bounce ideas off friends and colleagues. Some are skeptical.


The boring but significant bit

Rob files the necessary paperwork and incorporates Koyfin Inc. He pats himself on the back for a job well done and gets down to work.


Bootstrap for the win

Rob bootsraps Koyfin for the first couple of years. With a background in data & analytics Rob knew how the product needed to function but wasn’t sure he could build it. Enter Rich.


He’s back!

After seeing what Rob was doing via LinkedIn, Rich reaches out and they immediately start to riff off one another. Rich bridges the gap between engineer & product by teaching himself how to code. As you do.


Overseas expansion

Our office in Ukraine opens where Rob and Rich lead a remote team of three full-time developers. Developers four, five, and six follow shortly after.


v1 launches to crickets

We excitedly launch our first product and the world celebrates / doesn’t really notice. v1 wasn’t pretty but boy was it powerful.


Where is everyone?

With slow uptake, Rob leverages his network and pitches anywhere that will have him. At one event at Colombia Business School, 30 users sign up in an hour and effectively double our user base. However, people were starting to take note…


Time to take off the brakes

Some big players take notice and after two years of bootstrapping, it was time for outside capital. Craft Ventures and Social Leverage come on board in our Seed funding round.


The working world shifts

A worldwide pandemic hits and suddenly investors can no longer access their shared Bloomberg terminal. Koyfin’s mature product becomes an attractive option to an adapting workforce and our userbase sees a huge bump.


We were right all along

We launch widgets and dashboards to some initial pushback. Before long, people realize how totally awesome this is and these features become the core of our product offering.


What’s in a logo?

The brand gets some life injected into it and KOYFIN becomes a little less shouty.


Paid Plans

The next step in our evolution sees us launch paid plans, providing advanced tools for advanced users whilst maintaining a powerful free option for everyone else.


!Hola Argentina!

Our team continues to grow with Alejandro waving a tiny Koyfin flag in Buenos Aires.


Going mobile

We soft launch our mobile app. It’s a work in progress.


Fresh threads

Our website gets a much-needed overhaul which includes this super funny timeline. World domination surely follows.

The future

Watch this space

Koyfin’s team has grown to 30 full-time employees across the world but this is just the start. Rob and Rich have big plans.
