I help close the gap between the story we tell ourselves and what we're actually doing.
Jonathan Engle is an entrepreneur at heart, a soldier polyglot, and obsessed with what AI can do. He co-founded The Startup Stack, grew it over five years, and sold it to Startup Science in 2025, where he then led marketing through mid-2026. He founded Kingsfoil Health, a health insurance brokerage for startups, in 2024, and coaches early-stage founders on go-to-market strategy, sales systems, and CRM architecture. He speaks English, Russian, Spanish, and Portuguese.
Building a company's already hard, but it was even harder for me for some reason. Turns out some of that was learning about ADHD later in life. There's always a gap between ambition and reality, and my self-awareness and experience have helped me achieve my goals more than ever before.
I work with founders on the unglamorous work of building their companies. The greatest gift a founder can have is someone you can trust to jump in and start solving their most expensive problems.

Backstory
I was adopted at birth, grew up in Provo, Utah, and spent most of my 20s collecting a weird hodgepodge of experiences. I started in real estate (not my favorite), moved to Paraguay to run a franchise, helped start a new impact investment fund, and then helped launch a fintech startup tasked with finding a scalable GTM motion from scratch.
The Paraguay chapter is the one I come back to most, because it was the perfect wild west. I didn't speak Spanish when I got there, so I had to learn the language and the business of Elevate Global at the same time. I lived in Ciudad del Este to revive their worst-performing franchise in the country, working through local leadership to rebuild the people and the processes. Startups are really hard, and that one was especially difficult.
I started The Startup Stack in 2020 as a directory for startup resources. Over five years it became something more: an ecosystem builder connecting founders with the organizations that support them. I nurtured hundreds of relationships across software and service providers, startup support organizations, and more. We were acquired by Startup Science in May 2025.
The numbers behind all of that, role by role, are on one page.

I learned something about myself when a friend helped me recognize that I was ADHD. The official diagnosis didn't change a lot, but it explained a lot. Since then I've been learning to manage my chaos as a creator, and the systems I'd been building to do exactly that suddenly made more sense. It's incredibly rewarding to validate a founder for who they are and help them adapt into who they want to be.

I've served since 2021. I'm proud of both Utah and the United States, and I'm proud to serve alongside my fellow Utahns as a soldier linguist.

A few other things
I played French horn for over a decade, lift weights, practice martial arts, and recently got into Magic: The Gathering. I've been nerding out on Warhammer 40K lore. I'm nostalgic for RuneScape and PlayStation 2 but still hop on Steam for some good computer gaming. I enjoy a good show or film. I prepare various caffeine sources, like coffee or yerba maté.
I grew up Mormon and have since learned to love and embrace many sources of spiritual nourishment, Norse and Buddhist and Hindu traditions among them. I'm at the least culturally Mormon, and I'm generally a fan of Jesus.
Think we'd work well together?
If you're an early-stage founder stuck on go-to-market, sales systems, or just the gap between the plan and the doing, let's talk.
