Frequently Asked Questions

What's the cheapest demo software for startups?

Free: Storylane free tier (limited demos) + Arcade free plan (3 demos). Low cost: Supademo (£27/user/mo). Outcome-aligned: Naoma pay-per-demo - zero cost when you have zero demos. Match to volume expectations. Try Naoma.

Should bootstrapped startups pay for AI demo agents?

If you're getting inbound traffic, yes. The 2-5x conversion lift from Naoma pays back within 2-3 customers. Pre-traffic: use free HTML tour (Storylane, Arcade) until you have enough inbound to justify pay-per-demo economics.

What demo software works for pre-PMF startups?

Storylane free tier + Naoma pay-per-demo both work at pre-PMF stage. Both ship in hours. Don't buy enterprise demo tools (Reprise, Walnut) before £1M ARR - the overhead kills momentum.

How long does demo software take to set up for a solo founder?

Naoma: 60-minute SDK install (solo founder friendly). Storylane: 1-2 hours for first tour. Arcade: Chrome extension record (30 minutes). Enterprise tools (Walnut, Reprise): days to weeks. For speed, Naoma wins. See SDK.

Do startups need both AI demo agents and HTML tours?

Not at pre-PMF. Start with one - either Naoma for live AI on demo CTA, or Storylane free for product page tours. Add the second tool after hitting £1-5K MRR. Premature stacking wastes time.

Is a live AI demo agent worth it for a bootstrapped startup?

If you're getting 1K+ monthly visitors, yes. Naoma's 6-20% conversion vs 1-3% forms is the difference between 20 customers per month and 5. Pay-per-demo scales with success - cheap when quiet, expensive when winning. Try Naoma.
