Superday AI
Investment Banking Interview Prep
About
Superday AI is an interview prep platform built for students recruiting for investment banking and other competitive finance roles. The platform helps candidates understand where they stand, identify gaps, and practice the skills that actually matter in interviews. Users can assess their odds with Chance Me, drill technical questions across accounting, valuation, M&A, LBOs, and behavioral topics, and receive AI-powered feedback on their answers. Superday AI also supports mock interviews, resume-driven coaching, progress tracking, and targeted practice designed to improve weak areas over time. Instead of generic study guides or passive flashcards, Superday AI gives aspiring bankers an interactive training environment that mirrors the pressure and structure of real recruiting. The goal is simple: help students become sharper, more confident, and better prepared to convert networking, interviews, and internship opportunities into offers.

Your subject line needs to be simple — it needs to either be very short or very long. Are you putting everything in the subject line and the body is basically just here's the contact information? Or are you trying to say please look at this because XYZ very short very simple and then get in there and make your pitch.
Your subject line has 2 seconds — keep it ultra-short or put everything in it
Most journalists scan sender and subject line — nothing else. Two strategies work: cram all the signal into a long subject so opening is optional, or write a tiny subject hook that pulls them in to a short body. Everything in between — medium-length subject with medium-length copy — gets ignored. News-hook pitches built around current events almost never work.
Instead of offering a 7-day free trial maybe you offer a 7-day pass that's two bucks and if there's a really low barrier to entry and the user sees a lot of value then you kind of get them in at this cheaper price and then if they do see a ton of value that's the on-ramp to the subscription.
A $2 Paid 7-Day Pass Beats a Free Trial for High-COGS AI Apps
For apps with high cost of goods — particularly AI apps where inference costs are real — a 7-day paid pass at $2 replaces a free trial. It filters out users who would never pay, generates contribution margin to offset inference costs, and still provides the on-ramp experience. Users who complete a $2 week have already demonstrated willingness to pay before committing to an annual subscription.
There's a play for whatever you're stuck on.
