Handler is a vibe marketing agent for app marketers. It helps app teams find outlier TikToks, understand what makes them work, and turn proven patterns into clearer creative direction. Todayโs launch focuses on Handler and TikSpy: research winners faster, reduce manual scrolling, and know what to test next.
Opportuna is a real-time cryptocurrency arbitrage platform that helps traders spot profitable price differences across 12+ exchanges - without needing API keys or coding skills.
We monitor live price data across major exchanges including Binance, Bybit, OKX, KuCoin, and more, surfacing two types of arbitrage opportunities:
Most arbitrage tools either require API keys, limit you to a few exchanges, or show stale data. Opportuna is built for traders who want to find opportunities fast without spending hours configuring tools or manually checking exchanges
Handler
OpportunaHandler's answer
Handler is built specifically for app marketers who want to find what is already working on TikTok. Instead of guessing content ideas, Handler helps teams discover outlier TikToks, understand winning patterns, and decide what to test next.
Opportuna's answer:
Opportuna combines real-time data, multi-exchange coverage, and zero setup friction in one platform. Unlike competitors that require API keys or limit you to a few exchanges, Opportuna monitors 12+ exchanges out of the box with live updates. We also cover both spot arbitrage and funding rate arbitrage in a single dashboard, and offer a genuinely useful free tier - no credit card, no API setup, just open and start scanning.
Handler's answer
Handler is focused on TikTok research for app growth, not generic social media management. It helps marketers move faster from โwhat should we post?โ to clear creative direction based on real winning TikToks.
Opportuna's answer:
Three reasons: (1) No API keys required. Works immediately without connecting your exchange accounts (2) Real-time data. Not delayed or historical snapshots (3) Free tier with full scanner access. You can validate the value before paying. Most competitors either paywall the scanner, require complex API setup, or show stale data. Opportuna is built for traders who want to find opportunities fast, not spend hours configuring tools.
Handler's answer
Handler is made for app founders, growth marketers, mobile app teams, indie app builders, and agencies that use TikTok to grow consumer apps.
Opportuna's answer:
Crypto traders doing or interested in arbitrage - ranging from beginners exploring market-neutral strategies to experienced arbitrageurs managing capital across multiple exchanges. Our users typically have $1K-$100K in trading capital and want to automate the manual grind of checking exchanges for price differences. They value time efficiency, data accuracy, and tools that work on mobile since many trade on the go.
Handler's answer
Handler was created because app teams spend too much time manually scrolling TikTok trying to understand what content works. We built it to make TikTok research faster, clearer, and more repeatable for app marketers.
Handler's answer
Handler uses AI analysis, TikTok content research, video metadata extraction, creative pattern detection, and a web-based dashboard to help app marketers find and understand winning TikToks.
Handler's answer
Handler is currently early, so we are not publishing customer names yet. The product is built for app founders, consumer app teams, growth marketers, and agencies working on TikTok-based app growth.
