After his graduation from Hogwarts, he invented the Sleekeazy's Hair Potion, in doing so founded a potion-making company. Entrepreneurship and business acumen: Fleamont was known to have quadrupled his family's fortune with his potion-making company, and had sold his company upon his retirement for a vast profit.
The Potters' generational wealth is traced back to their ancestor, Linfred of Stinchcombe, who amassed a great fortune through his medicinal services and inventions of healing potions.
As Ilovecats13 and DelphianDragon said, James' father Fleamont quadrupled the family's gold by inventing Sleekeazy's Hair Potion (the same that Hermione used before the Yule Ball to tame her mane). The family fortune was passed down to James, their only child, and then onto Harry. Rowling wrote about it on Pottermore.
He was descended from great potioneers such as Linfred of Stinchcombe, his earliest ancestor and creator of an early version of the Pepperup Potion. He was also descended from Fleamont Potter, creator of Sleekeazy's Hair Potion (or simply Sleekeazy), which quadrupled the family fortune.

The REAL Reason the Weasleys Are So POOR (They're CURSED) - Harry Potter Theory
Why did James and Lily have so much money?
James Potter's parents, Harry's grandparents, were the inventors of the Sleekeazy Hair Potion, which became wildly popular. Unfortunately, they died of dragon pox before Harry was born, and as James being the only heir, that money went to him.
Advancing in age, both Euphemia and her husband Fleamont succumbed to Dragon Pox shortly after the marriage of their son James to Lily Evans, in 1978–1979, dying within days of each other.
Now for the Malfoys. They had about 321,000,000 galleons, about 2.2 billion dollars, and 1.6 billion pounds. They were probably some of the richest families.
Harry's father James and godfather Sirius Black worked for three years during their time at Hogwarts to become Animagi to keep their friend Remus Lupin company during the full moon.
It was confirmed on Pottermore that Hermione was also a bit of a Hatstall, as the Sorting Hat saw the potential for her to be both Ravenclaw and Gryffindor. In the end, Gryffindor won out, and it's possible that Hermione wanted to be seen for being brave more than for her intelligence.
This idea was incredibly embarrassing to him since Ron vehemently did not want to be cared for by his rich and famous best friend. This is precisely why Harry never tried to give the Weasleys money or give Ron lavish gifts - they didn't want pity.
At the beginning of the first book, Gringotts Vault 713, a higher-security vault, held a small grubby bag, which we later learn contains the Philosopher's Stone. Albus Dumbledore sends Hagrid to retrieve it while he escorts Harry to Diagon Alley.
History. When the Weasleys entered it in the summer of 1992, the vault contained only a small pile of Sickles and a single Galleon, all of which Molly Weasley took out. The total number of coins at that time totalled 1 Galleon and 58 Sickles.
As Sirius Black's cousin, she is a member of one of the wealthiest Wizarding families, the House of Black. Harry Potter's Bellatrix Lestrange inherited much of her parents' vast fortune and possessions upon their demise, which were shared among her sisters.
I believe that both James and Lily were employed at Hogwarts – James as the DADA teacher and Lily as the Charms teacher. The lack of a qualified DADA candidate has been a very important theme at the start of each book.
Since Harry inherited the Cloak indirectly from his father, many have wondered how James Potter came to possess it. James inherited the Cloak from his father, Fleamont Potter, who inherited it as a descendant of Iolanthe Peverell — a granddaughter of Ignotus Peverell.
One of the wealthiest Wizarding families in Britain, the Malfoys were known for their connections to other pureblood families and their covert influence over the magical government. In contrast to the Weasleys, the Malfoys were traditionally sorted into Slytherin and supported pureblood supremacy.
The reason Snape and Lily ended their friendship was his moving to the dark side. He spreads his devotion between both light and dark, but, after he kills Dumbledore, it's revealed this was all arranged. After Lily's death, Snape firmly makes up his mind that he won't support Voldemort, and he wants to stop him.
James was slightly better because he truly did change and he allied with the Order out of basic morality compared to Snape who stayed an all around bitter person. and only allied with the Order out of love for Lily.
