Jim + Kat

Senior People.
Still in the Room.

We built FaasHaus around a simple belief: the people who understand the problem should be the people helping you solve it.

The founders

Partners in life.Partners in the difficult work.

Jim and Kat met while working at an agency in New York. They became known internally as the “Dynamic Duo” because they could step into difficult digital projects together and get them done.

Their partnership brings together Jim’s ability to make complex technology clear, stable, and real with Kat’s ability to connect business strategy, customer experience, and delivery.

After leadership roles—including CTO for Jim and VP of Technology for Kat—across Rokkan, Razorfish, and other Publicis Groupe agencies, they founded FaasHaus in 2019 to preserve the best part of that partnership: two senior people, close to the work, solving the whole problem together.

James “Jim” Blackwelder

Engineering for complex systems that last.

Miami born and raised, Jim brings closer to three decades of engineering and technology leadership. He has spent his career turning difficult requirements into platforms that work—and helping teams find the calmest path through technical complexity.

He cares about the details users never see: architecture, performance, reliability, maintainability, integrations, and all the quiet decisions that make a product feel effortless.

Katarina “Kat” Blackwelder

Strategy that can survive contact with reality.

Born and raised in Slovakia, Kat immigrated to the United States at age nine. A first-generation immigrant and female business owner, she brings roughly two decades of digital strategy, UX, development, and technology leadership.

She is at her best where customer needs, commercial priorities, creative ambition, and delivery constraints all have to become one coherent plan. She asks the uncomfortable useful questions early, makes the complex understandable, and keeps the work anchored to what the business actually needs to change.

How we work together

Different angles.
One coherent system.

Engineering and experience inform each other from the start. We work through the tradeoffs together, so the decisions hold up for your business and the people using what we build.

Where it comes together

Debate the tradeoffs.
Build the shared answer.

When we disagree, we work it through—often finding we’re approaching the same outcome from different angles. Technical reality and creative ambition shape the answer together.

You get a clear direction, with both of us accountable for making it work.

Why boutique

We left the handoffs behind.

Large agencies can do impressive work. Jim and Kat know; they helped lead it for major global and Fortune 500 brands.

But the conventional model often puts distance between the people who sell the thinking and the people who deliver it. FaasHaus operates differently. The founders own the decisions. Communication is direct. Context stays intact. Clients are not sold senior expertise and quietly handed to a junior delivery team.

Small is not a limitation here. It is how the work stays sharp, accountable, and human.

Bring Us the Complicated Part.

If the work crosses strategy, experience, and technology, that is usually where we are most useful.
