With so many options, how do you actually decide? Here’s my personal checklist:
Define your stage first Are you pre-revenue? Building an MVP? Scaling post-funding? Your stage determines which agency type fits best. Early-stage startups need lean, flexible partners. Growth-stage startups need agencies that can scale.
Check their startup portfolio Any agency can claim they work with startups. Look at their actual case studies. Do they have experience with products at your stage and in your industry?
Ask about communication The best software development for startups agencies communicate like partners, not vendors. Weekly demos, Slack access, and transparent progress tracking are non-negotiables.
