Naoma vs Karumi: Which AI Product Demo Agent Should You Put on Your Website?

Quick Takeaways

• Naoma and Karumi both put a live AI agent in front of your website visitors to demo real software on demand; Karumi is a voice-and-screen agent at a flat $900 per month, while Naoma is a full-cycle AI account executive with realistic, branded, and animated avatars, prospect memory, and engagement-based billing from $299 per month.
• Karumi, a Y Combinator Fall 2025 startup, joins live video calls 24/7 and drives the real product through autonomous browser control; it advertises SOC 2 and ISO 27001 and publishes its pricing, both rare for a company this young.
• Karumi's Self-Serve plan includes one AI agent and one language; more languages sit in its custom Enterprise tier. Every Naoma plan ships 33 auto-detected languages and the website widget with a built-in chat bot.
• Naoma bills only for demos that hold a prospect 3+ minutes, with bounces free; Karumi charges its flat fee however the month goes.
• The verifiable track record diverges sharply as of August 2026: Naoma has conducted more than 50,000 AI demos and holds a 4.9 on G2 and a 5.0 on Product Hunt, while Karumi's G2 profile shows a single review.

Buyers who land on your pricing page tonight do not want a calendar link; they want to see the product now. That demand created the live AI demo agent: software that greets a visitor, runs a real walkthrough, answers objections, and qualifies the lead while your team sleeps. Naoma and Karumi are two of the category's most direct rivals — often the last two tabs open in an evaluation.

One honest note before the head-to-head: both vendors are early-stage. Karumi came out of Y Combinator's Fall 2025 batch, runs on a roughly seven-person San Francisco team, and has raised $500K from YC as of August 2026. The useful question is not which vendor is a finished institution — neither is — but whose product, pricing model, and proof you can verify before you sign.

Quick comparison

What Karumi does

Karumi describes itself as an agentic demo platform for instant, personalized product demos in live video calls, 24/7 — Y Combinator's directory pitches it as "the Waymo of personalized demos." When a prospect asks for a demo — from a landing page, in-app, or an outbound email link — a Karumi agent joins a live video call, talks with the buyer, and drives the product through autonomous browser control, navigating the live application or a sandboxed copy in real time, with session recording and browser isolation.

The engineering around the edges is mature for the company's age. Transcripts, analysis, and next steps log directly into your CRM, and the $900 Self-Serve plan includes CRM export and an MCP connection. Security is a genuine differentiator for a seed-stage vendor: SOC 2 and ISO 27001 plus GDPR and role-based access control, with SOC 2 Type II listed on the Enterprise tier. Founders Toni Lopez and Pablo Omenaca (ex-StackAI) publish their own LLM research, and named testimonials come from Re-Leased, Salesforge, and Clay. You can also experience Karumi instantly — its site offers a "Launch Demo Now" call rather than only a sales form.

What Karumi lacks as of August 2026: any avatar (the agent is voice plus screen), claimed prospect memory, more than one language below Enterprise, or a meaningful public review base.

What Naoma does

Naoma is a full-cycle AI account executive for inbound. A visitor clicks one button and lands in a live conversation: the Naoma AI demo agent runs discovery first, then adapts the demo to what it heard — slides, your real product driven live in a browser session, and branching journeys on higher plans. It handles objections, qualifies the prospect, and books the meeting or routes the buyer straight to signup and checkout, writing everything back to your CRM. It speaks 33 languages, auto-detected and switchable mid-demo, and every plan includes the high-converting website widget with a built-in chat bot.

Reading about a demo agent is a contradiction. Talk to ours right now — this is the actual product:

The demo itself: a voice on a screen share vs an agent with a face and a memory

Both products clear the bar that matters most — a real conversation over your real product — putting them ahead of scripted tour builders. Three differences shape how the demo feels.

Presence. Karumi's agent is a voice narrating a browser. Naoma puts a face on the call: best-in-class realistic avatars, branded avatars and mascots, and animated characters like the signature Naoma agent, with custom avatars built for customers who want the agent fully on-brand — part of why 89% of Naoma's end users mention the best-in-class human feel.

Memory. Karumi claims sentiment analysis of prospect engagement, but no memory of the prospect. Naoma pairs prospect memory across sessions with account enrichment, so the agent knows who it is talking to and recognizes returning prospects. Demos adapt to the buyer's needs, industry, and role; Scale and Enterprise add branching journeys and deep personalization.

Speed and languages. Karumi markets "the lowest latency in the market," though it publishes no benchmark. Naoma runs an in-house stack with roughly 20% faster conversational reaction than an ElevenLabs stack — and where Karumi's paid entry includes a single language, every Naoma plan carries all 33.

Pricing models: a flat $900 vs paying when a prospect actually engages

Karumi deserves credit for publishing pricing at all; much of this market hides behind a sales form. Its published plan is Self-Serve at $900 per month for one AI agent, one language, and three seats, with custom Enterprise above and no published annual discount. You can buy that plan with a click today — no free trial, but a real checkout.

Naoma publishes every tier on its pricing page: Starter at $299/mo for 50 engaged demos, Growth at $900/mo for 100 with live product walkthroughs, Scale at $2,500/mo for 300 with two agents, branching journeys, deep personalization, and a dedicated demo engineer, plus custom Enterprise with SSO and an SLA. Annual billing drops those to $249, $750, and $2,083 — the lowest published entry price in the demo-first segment.

The structural difference is what you pay for. A Naoma demo becomes chargeable only after 3 minutes of real engagement; bounces cost nothing. A flat subscription bills the same whether prospects showed up or not. Model your own traffic through the ROI calculator to see what that gap is worth. One honest note: Naoma's self-serve purchase and free trial arrive in September 2026, so today every plan starts with a quote request or booked walkthrough — for now, Karumi's instant checkout is a convenience Naoma lacks.

Proof: what each vendor can show you as of August 2026

Naoma's claims are checkable from your desk. It has conducted more than 50,000 AI demos. In the published AiSDR case study, 53% of demos ran 3 minutes or longer, the average conversation lasted 7 minutes 50 seconds, a quarter of sessions passed the 10-minute mark, 21% of demos produced a qualified lead, and 6% ended with a meeting booked. Naoma holds a 4.9 on G2 and a 5.0 on Product Hunt, where it was #1 Product of the Day and #1 Product of the Month in Marketing; 77% of end users praise its interruption handling, and under 2% of sessions hit any technical issue.

Karumi's public proof is thinner: a company-sourced claim of 1,000+ AI demos within 24 hours of launch, named testimonials, StackAI and Salesforge case studies — and a G2 profile showing 4.5 from a single review as of August 2026. That lone reviewer praises the instant, no-scheduling demo while noting the agent is "still improving" at sounding natural. Testimonials are a positive signal; they are not a review base a buyer can browse.

Where Karumi fits, and where Naoma wins

Choose Karumi if your motion is strictly video-call demos in one language, you want security paperwork on the table from day one — its SOC 2 Type II and ISO 27001 stand against Naoma's GDPR compliance with SOC 2 still in progress — and you value swiping a card for the $900 plan this afternoon. It is a credible, technically serious young product.

Choose Naoma if you want the fuller account-executive motion: an avatar-led agent that remembers prospects and enriches accounts, all 33 languages and the widget with built-in chat bot on every plan, billing that counts only engaged demos from $299/mo, and proof — more than 50,000 AI demos, published case rates, a 4.9 on G2 — you can verify before the first call.
