Modelence raises $3M to smooth out the vibe-coding stack

As AI tools have democratized software engineering, a new generation of users has emerged, eager to build their own apps. But just as large language models speed up the coding process, the old problems of hosting, security, and general DevOps have persisted.

There is an obvious business opportunity in solving that problem, but with the system changing so quickly, it is hard to know how to grab hold of it. One of the more interesting answers comes from Modelence, a Y Combinator startup from this summer’s batch that announced it raised a three million dollar seed round. Y Combinator led the round, with participation from Rebel Fund, Acacia Venture Capital Partners, Formosa VC, and Vocal Ventures.

Modelence is not the only company going after this sector. Giants like Google and Amazon, as well as smaller startups, are all trying to solve the infrastructure issue. California-based Modelence stands out for how it is diagnosing the problem. For CEO Aram Shatakhtsyan, the issue is not individual services; it is the connections between them.

He explained that you do not want to ask AI to build authentication, then set up a database, and then connect them together, because it is very likely to break. This is an interesting diagnosis because it explains how there can be so many world-class service providers contributing to such a rickety system.

Shatakhtsyan noted that while services like Vercel cover most of your front end, and Supabase covers the database and the layer on top of it, you still have to stitch the rest together. In the best case, you get two cloud systems, which leaves a lot of room to make mistakes.

Modelence’s approach is to provide something like an all-in-one service. Their framework works on TypeScript, with the company handling authentication, databases, hosting, LLM observability tools, and even their own app builder to eliminate the extra friction.

It is an interesting idea, and it will be fun to see if they can draw in users. But with the landscape for code-adjacent tools changing this fast, it will be a real challenge just keeping up.
