The odds are much better that you can repeat after your first success. Most startups fail before gaining significant funding, if you have enough capital to skip the seed stage and a good relationship with investors and have experience with running a startup then you have much higher odds. To use some famous examples, Apple/Next/Pixar, Paypal/Tesla /Spacex/Solar City they both had a weaker startup such as Next and Solar City but leveraged past success to avoid failure.
