Gains app founder cuts debt and builds savings

His experience also reflects the economics of credit addiction. By age 25, he was sending roughly a third of his wages to interest repayments, had damaged his credit score and could not even rent a flat, a reminder that expensive revolving debt can choke household mobility and delay consumption. The fix was not a windfall but extra labour: he said the side hustles brought in about £2,000 a month, all of which went toward debt reduction.

Once debt-free, King shifted the same cash flow into a savings account and a Stocks and Shares ISA, eventually contributing £100,000 of the total himself and letting investment returns do the rest. He says his portfolio generated more than the average UK salary last year, an outcome that speaks to the compounding power of early balance-sheet repair in a lower-rate but still cautious consumer environment.

That backdrop matters for fintech and consumer-credit investors because demand is rising for budgeting and cashback products pitched at households trying to survive a high cost-of-living cycle. King has since launched the Gains app, which now has more than 13,000 users, after earlier building the Up the Gains website and podcast, which he says has reached more than one million people.

The broader narrative is one of financial self-help meeting a market opportunity: consumers want clearer visibility over spending, while lenders and fintechs are competing for the same customers with products tied to budgeting, credit rebuilding and rewards. The next test is whether his app can convert that demand into a durable user base as Britain’s household debt pressures and spending restraint continue to shape the market.
