$142k/mo profit · zero tech staff
I'm not technical at all. All I had was an idea and a Telegram channel with 18k followers. One-time fixed payment + 45 days later → fully functional neobank with cards, wallets, and fiat on/off ramps. Today: 9,200 active cards, ~$19 ARPU, roughly $142k net profit per month. Tech headcount on my side: zero. BroLabel genuinely lets one guy with a laptop compete against 50-person teams.

$400k/mo revenue · 19 days to launch
We went live with fully branded crypto cards and an OTC desk in just 19 days. Before BroLabel, we burned 6 months with two Indian outsourcing teams — nothing but bugs and "10 TPS throughput". Here we got SOC 2 compliance, $150k+ limits per card, and zero slippage liquidity even on $2–3M trades. First month after launch: $187k net profit from cards alone. Now we're approaching $400k/month — still zero developers on our payroll.

$60M monthly volume · zero incidents
We were hunting for a true Fireblocks + in-house custody replacement. BroLabel delivered MPC + HSM-grade security, built-in Travel Rule, and sanctions screening — all for a one-time fixed fee. In 28 days we migrated every cold wallet and launched a white-label OTC desk with direct books from 30+ Tier-1 brokers. We're now doing $35–60M monthly volume at 0.35–0.6% margin. Zero devops headcount, zero incidents in 7 months.
