Alex Zosel told the BBC that his device was safer than a traditional helicopter because its systems had more redundancy built-in.
The Volocopter can continue to fly if some of its batteries or rotors fail, and can land itself when battery power is low.
However, the multicopter can currently fly for only 25 minutes and is expected to cost Â£200,000 when it goes on sale.

It said it does not intend to demolish any houses to make room for the multi-million-pounds stadium.
Senior official Stephen McGeehan said the GAA is willing to consider a capacity below 38,000, the number of seats in the original redesign plan.
A new community consultation about the proposal was announced on Tuesday.
"The GAA has no intention, and never had, of knocking people's houses down, of purchasing or demolishing anyone's homes," said Mr McGeehan, who is the Casement Park project manager.
Planning permission for the stadium's redevelopment was overturned in 2014 and since then the GAA has been working on a new planning application.
The GAA said it wants to hear feedback from people in west Belfast and further afield about the proposed new stadium and has organised a number of consultation initiatives.

The GAA said the redesigned stadium will take into account the fears over the emergency exiting arrangements in the original design.

The 33-year-old has not played for Celtic since Brendan Rodgers took over as manager at the start of the season, and will provide midfield cover.
Hibs are currently without John McGinn and Fraser Fyvie until January, while Dylan McGeouch suffered an ankle injury in training this week.
Commons could feature against Morton on Saturday.
"Kris is an experienced, technically gifted player," said head coach Neil Lennon.
"So him coming in at this time is of benefit to the side as the games start coming in over the festive period.
"With us missing a lot of our regular midfield players, it is good to bring in someone with a lot to offer, even just on a short-term basis."
Commons, who was a key player for Lennon during his time in charge of the Scottish champions, says that the deal can be beneficial for both parties.
"It has come about very quickly, but I think it makes sense on both parts," he said. "I can try to get some football under my belt and give Hibs a helping hand as well.
"As much as I am trying to help Hibs, the club are trying to help me out a lot, so I'm grateful to them for giving me the opportunity to play football. I'm also thoroughly looking forward to hopefully helping them on the way and putting on the jersey and doing my best."
Hibs remain top of the Scottish Championship on goal difference, though the Edinburgh side have lost their points advantage over Dundee United in recent weeks.
The two pre-season favourites for the title are eight points ahead of Falkirk, with Morton another three behind.
Commons joined Celtic in January 2011, but his current contract is due to expire at the end of the season.
