 I know (or believe) that there is nothing in canon, but can anyone
speculate?

Carol again:
Glad you liked my timeline. I like the idea that in his DE/spy days he
had a potions shop in Diagon Alley, outwardly perfectly respectable,
with a lab in the basement, opened with the financial help of Lucius
Malfoy (something similar to Harry's arrangement with the Weasley
Twins but on a larger scale). In addition to selling legal potions,
the shop was a front for a less savory business connection--poisons,
antidotes, and other potions made for Voldemort's use, not only
against his enemies but to aid LV in his quest for immortality. An
arrangement of that sort would help to explain the Lucius Malfoy
connection (Snape owes him a debt of friendship as well as money) and
would also be an additional cause for remorse when Snape turned
against Voldemort.

I don't think there's more than a shred or two of canon evidence for
this scenario, but I like it.

Carol, just speculating as requested
