Beyond the YC portfolio.
Handpicked tech and startup jobs, not just the Y Combinator catalog.
A YC member benefit, not a candidate product
Work at a Startup was built for YC's portfolio, not for you
Work at a Startup runs as portfolio infrastructure for Y Combinator. It exists to funnel candidate applications into YC's roughly 1,000 backed companies, with a single profile that lets you submit to hundreds of roles in a click. That mechanic is great for YC, because it concentrates supply into their portfolio. It has become less great for candidates, because the same mechanic is what poisons the queue.
The product has barely evolved. One Hacker News post famously framed it as a rarely mentioned benefit of YC, which tells you how much engineering attention it receives compared to YC's main product. There is no public API. The application flow forces every user to pick a single role bucket via a radio button that locks the rest of the account into that category. Hotfix is the broader-startup alternative built for candidates, not for a portfolio.
Why people leave
What candidates keep saying about Work at a Startup
The most structural complaint is the scope cap. Every company on Work at a Startup is YC-backed, by design. For a candidate whose taste was formed by YC companies but who would also take a great seed-stage role at a non-YC startup, the entire frontier-lab cluster, the design-led non-YC studios, and the well-run bootstrapped category are all hidden by the funnel. The constraint is a feature for YC and a hard ceiling for you.
The application mechanic is the second complaint. One profile, hundreds of jobs, founders see your application directly. That value proposition has collapsed under its own success. A YC founder on a recent Ask HN thread reported 172 daily applicants, of which 22 looked like real humans and 150 were primarily AI-generated. Candidates describe applying to twenty or thirty roles and hearing back from zero, calling the experience sending applications into oblivion. The volume mechanic is what enables the AI spam, and the AI spam is what makes founders stop reading.
The third complaint is product mechanics. The radio-button role lock means you can be good at frontend or devops, but not both, on a single account. The profile gates value, so casual browsing is friction. There is no real-time alerting for new roles that match your preferences. Listings are slow to refresh because the system optimizes for the founder pipeline, not for the candidate's hunting cycle.
Stacked together, these are not three small frustrations. They describe a product built as portfolio infrastructure for one investor, with all the constraints that come with that, and none of the candidate-side product investment a real job board would have made years ago.

The trade we made
Funnel efficiency is the wrong question
Work at a Startup optimizes for funnel efficiency, concentrating every YC company's hiring into one queue. Hotfix optimizes for fit, surfacing the roles where the company and the candidate actually match, regardless of who wrote the seed check. If you only want YC companies, Work at a Startup is the right tool. If your taste also includes the seed-stage spinouts from those companies, the not-YC frontier labs, and the wider category of well-run startups, the YC cap is doing real work against you.
Volume is not the same as fit. The value proposition of Work at a Startup is volume: one profile, hundreds of YC roles, founders see your application directly. That has become its biggest weakness, because every YC company is now competing for attention in the same queue, and the queue is overrun with the AI spam the mechanic enables. Hotfix's bet is that browsing without a login wall and applying to specific roles you care about beats blasting a profile into a single shared funnel.

Honest assessment
Where Work at a Startup is still the better pick
- Direct-to-founder pipeline at YC-backed companies. Work at a Startup is the official channel; no other product gets you in front of a YC founder this directly.
- Vetted catalog. If you trust YC's selection bar, you skip the diligence step entirely. The constraint is real curation.
- Single-profile efficiency for full YC coverage. If your goal is maximum coverage of the YC portfolio and you don't mind the queue noise, the one-profile mechanic genuinely saves time.
Pick the right tool
Who each one is for
Choose Hotfix if
Engineers, designers, PMs, and operators who like the kind of company YC funds but won't cap their search there. People who want to browse without signing up, get alerts the moment a fitting role posts, and apply to specific roles instead of blasting a profile into a shared queue.
Stick with Work at a Startup if
Candidates who specifically want a YC-backed company and value direct-to-founder access at the cost of a noisy applicant queue. Founders at YC-backed companies looking for sourcing through the official portfolio channel.
