TL;DR Aside listens to your sales calls and surfaces answers from your docs, Slack, and past calls, helping tech sales reps answer technical questions.

Hey 👋, we're Jun, Chanhee, and Sanghun, the founders of Aside.

Everyone’s using AI for sales these days - emails, outreach, everything - except the part that actually matters: the call.

❌ Problem: The Knowledge Gap in Sales

Sales reps often freeze when faced with technical questions. Like:

Are HSTS or strict transport policies enforced during data transmission?

Most say, “Let me get back to you”, and the deal cools off. That’s why teams burn $60K+ a year on coaching, mock calls, and LMS exams. I’ve paid that bill too.

But onboarding drags. Products change fast. Tech-savvy AEs are rare.

What if your reps could pull the right answers instantly– straight from your best calls, API docs, or Slack threads?

✨ Solution: Let your reps cheat on sales calls

Aside listens to your sales calls and surfaces real-time answers pulled from your docs, HubSpot, or past calls. It's like pressing 𝚌𝚝𝚛𝚕+𝚟 on your company’s knowledge into every rep – so anyone can sound like your best rep.

How it works

🔎 Get answers from your docs, Slack, and past winning calls.
When a tough question hits, just click “How can I answer?” - the right answer lands in 800ms. No guessing, no “let me get back to you”.

📝 Live coaching that catches what you miss
When you miss a key pain point, Aside flags it live — before the deal goes cold. It nudges what to ask next and coaches you using your playbook — BANT, SPICED, whatever your team runs on.

💬 Preload your cheatsheets as Live Cards
Turn your best answers into in-call cards that pop up right when you need them. No more flipping tabs — your best answers, ready the moment the question hits.

🎓 Coaching feedback, remembered by AI
After the call, Aside reviews what happened, gives you feedback, and turns it into live suggestions for the next one - so you never repeat the same mistake.

Hear from the founders

What is the core problem you are solving? Why is this a big problem? What made you decide to work on it?

Sales reps often freeze when faced with technical questions like:

Are HSTS or strict transport policies enforced during data transmission?

Most say, “Lemme get back to you.” The deal slows down.

That’s why tech sales teams spend 1.5 hours per week and $2,000 per rep each year on tools like Gong.io and Hyperbound. Enterprises like AWS and Oracle require internal exams and hire solution engineers for $200K+ to answer technical questions.

But these don’t solve the problem: reps still repeat mistakes, miss answers, and deals stall or fall through.
