Klutch is building the platform for financial mini-apps.
We're not just a credit card—we’re creating an extensible platform where powerful mini-apps help users control, understand, and automate their finances. From budgeting tools that prevent overspending to AI-driven insights that surface patterns in your spending, Klutch lets users shape how their credit card works for them.
Our core belief: financial products should be programmable, transparent, and intelligent.
We're looking for builders to help shape this vision:
Fullstack Developer – Kotlin + React. You'll ship end-to-end features, build new mini-apps, and contribute to the internal platform that powers them.
Product Designer – Help define a UX model for composable finance—where users can mix and match tools that feel tailored to them.
Product Manager – Own a domain like AI Insights or Budget Controls. You'll define the roadmap, talk to users, and launch products quickly.
We use Kotlin (Exposed, Ktor), React + Next.js, AWS (Fargate, Lambda), MySQL, and Mongo. Our stack also supports integrating AI models directly into mini-apps.
If you’re passionate about redefining how people interact with money—and want to help build a platform others can build on too—we’d love to talk.
Reach us at jobs [at] klutchcard.com and include a quick note about what excites you about programmable finance.

Hi, I’m Yanni Giannaros, founder & CEO of Axle (www.axleruns.com). We build AI agents that automate AML/KYC compliance workflows for fintechs, banks, and crypto companies. We’ve raised $3.2M and are live with dozens of enterprise customers. Our agents eliminate manual review bottlenecks, helping teams focus on complex cases and operate more efficiently. We found product-market fit and we're gearing up to scale. My cofounder and I have built and sold Fintech companies before this and we care deeply about this problem.
Headcount: ~8
Stack: Python, Go, Next.js, Postgres, GCP, SOTA LLMs
Shoot me an e-mail here: yanni[at]axleruns.com
Thank you!
At Edra we built a new, proprietary method of learning that allows LLMs to understand and automate business processes.
Founded by Eugen and Yannis, former co-heads of Forward Deployed AI Engineering at Palantir. We believe that as we get closer to AGI, the ability to teach models what you want them to do will become the key bottleneck in deployment to enterprises, and traditional training approaches won’t cut it. We named the company Edra for “the seat of the teacher”.
Edra AI is a novel learning system, deployed with several customers and are looking to scale up. Backed by top-tier investors from the Palantir ecosystem with offices in New York and London.
Still in stealth, reach out to hiring@edra.ai for more.

- AI Engineers (New York/London): You’ll work on building the future of AI whitebox learning
