We are working together for 2 years now in our new startup - we have created great products that help people to manage their finances better! At this time I can say only good things about my experience here at HV so far (and it's not just me).
They helped us build amazing team from scratch; they were always available when needed them most; gave advice what would be best approach towards certain problems you might face while building your app/product etc.; did all necessary paperwork required by local authorities which was very helpful during initial stages of founding process ; provided access into relevant networks within financial sector allowing easy integration between existing clients & potential users / customers; made sure everything went smoothly even if there wasn't much communication involved throughout whole project life cycle due to distance or other reasons!
