Pros & Cons
Fireworks AI
- World-class team of ex-Meta AI infrastructure engineers — technically very strong peers
- Working on LLM inference optimization which is one of the hottest areas in AI infrastructure
- Early-stage startup intensity with long hours expected and high performance bar
- Small team and rapidly evolving product means less structure, process, and career laddering
Supabase
- Truly open-source DNA — build products millions of developers use daily
- No-hierarchy remote culture with extreme autonomy and generous allowances
- Intense workload — more work than a single person can reasonably manage
- Work-life balance rated 3.0/5 — fast shipping pace can be relentless
Bottom Line
Fireworks AI
Choose Fireworks AI if you want to work with ex-Meta AI infrastructure engineers on cutting-edge LLM inference — but expect early-stage startup intensity and limited structure.
Supabase
Egoless, fully remote culture with just one meeting per week and extreme autonomy — but the relentless shipping pace means work-life balance takes a hit.
