There’s no single “best,” but for most startups I’ve seen, tools like BambooHR, Zoho People, and Gusto (if you need payroll too) are solid picks because they’re easy to set up and don’t feel overwhelming; if you want something more modern and scalable, Rippling is great since it combines HR, IT, and payroll in one place, though it can get pricey as you grow, personally, I’d start with Zoho or BambooHR and only switch if you outgrow them.
