Sable vs Supersonik: The Best-Funded AI Demo Agents Compared (And a Third Option)

Quick Takeaways

• Sable and Supersonik are the two best-funded live AI demo agents: Sable is a $45M Sequoia- and 8VC-backed enterprise "AI employee" in production at Notion, Supersonik is an a16z-backed multilingual agent deployed at Salesforce and HubSpot, and as of August 2026 neither publishes pricing or has a single public review.
• Sable's agent Aidan handles customer calls with real-time browser use inside LiveBox, a virtual machine hosting a functional copy of your product, and stretches beyond demos into onboarding, certification, and training.
• Supersonik's agent starts a live video call, shares its screen, and operates your real product in 70+ languages, with Runway-built AI avatars (May 2026) and cross-session Memory (June 2026).
• Both sell through enterprise motions only: no free trial, no self-serve purchase, and a sales conversation before you ever see a number.
• Full disclosure: we build Naoma, a competing AI demo agent with published pricing from $299/mo, and it appears as the third option at the end of this comparison.

Let's put the conflict of interest on the table first: Naoma competes with both companies on this page. We wrote the comparison anyway because these are the most heavily funded entrants in the live-AI-demo category, buyers shortlist them together, and neither vendor has published a head-to-head. What follows is the fairest reading we can give from their own sites, investor materials, and press, with market facts anchored as of August 2026. At the end comes the case for a third option you can price without a sales call.

Quick comparison

What Sable does

Sable is the San Francisco startup behind Aidan, pitched as "the first AI employee powered by real-time browser use and vision" that runs customer calls at scale. Founded in October 2025 by four Harvard-connected founders, it announced a $45M round in July 2026 co-led by Sequoia Capital and 8VC, with both firms taking board seats. Fortune's telling of the deal is revealing: Sequoia's Shaun Maguire committed after watching Aidan glide from English into Mandarin and then Spanish in the middle of a demo.

The product bet is breadth. Aidan is positioned for product demos, qualification, onboarding, feature launches, partner certification, user training, new-hire training, and international expansion. It runs inside LiveBox, a virtual machine that hosts a functional copy of your product for shared, real-time interaction, and its full-duplex speech lets it listen while talking, so a customer can cut in at any point. The agent's brain is assembled by Sable from seller recordings, expert interviews, and marketing materials, and the company says it speaks dozens of languages, without publishing a count.

Deployment is the strongest card: Notion uses Aidan for setup sessions, demos, and partner enablement, Decagon has it in production, and Sable claims a 150+ company waitlist ahead of any public launch. Compliance is unusually deep for a company this young: SOC 2 Type II, ISO 27001, GDPR, and ISO 42001, the AI-management standard almost nobody in this market holds. There is no official product video to embed here, because none exists; as of August 2026 Sable has published no pricing and holds no reviews on G2, Capterra, or Product Hunt.

What Supersonik does

Supersonik, split between Barcelona and San Francisco and co-founded by ex-Typeform CEO Joaquim Lechà, raised a $5M seed led by Andreessen Horowitz in September 2025, with angels from Google, DeepMind, and Salesforce. Its agent answers the demo request instantly: it starts a live video call, shares its screen, logs into your real product, and operates it live while explaining each step, 24/7 and in 70+ languages, the widest published language range in the demo-first set.

Supersonik has shipped quickly through 2026. AI avatars arrived in May through a partnership with Runway, and June brought Memory, agents that remember every customer across sessions. The platform connects to 500+ systems including Salesforce, HubSpot, Slack, Zoom, and Microsoft Teams, and its enterprise controls, such as authenticated access, pre-production simulation, and session evaluation, are aimed squarely at large deployments, with a dedicated team running implementation for each customer. Positioning now spans the customer lifecycle: sales and marketing, customer success, and enablement.

Its customer proof is quantified in a way few rivals match. A July 2026 story describes Salesforce equipping its global SDR teams with Supersonik, with more than 250 SDRs enabled across three-plus regions; a May 2026 HubSpot campaign reached over 80,000 customers, with the longest sessions passing the hour mark. What is missing mirrors Sable: the pricing page is a consultation form, the AWS Marketplace listing sells exclusively through private offers, and there are no public reviews anywhere as of August 2026.

Product and platform: an AI employee in a VM vs a product expert on a call

Strip away the branding and the two products make different architectural bets.

Sable's LiveBox approach wraps your product in a controlled virtual machine. That buys reliability and shared interaction, since the agent and the customer can both touch the environment, and it supports Sable's wider ambition: the same "employee" that demos the product can later onboard users, certify partners, and train new hires. The tradeoff is that buyers watch a functional copy, not your live application, and the whole system is built for depth of deployment rather than speed of it.

Supersonik keeps the product real: the agent logs into your actual software and demonstrates it on a screen-share video call. Its bets are coverage and cadence. Coverage means 70+ languages and 500+ integrations; cadence means avatars in May, Memory in June, and quantified customer stories a month apart. On memory specifically, Supersonik's cross-session Memory (June 2026) is a claim Sable does not make; Sable's context graph learns at the organization level, not per prospect.

On conversation quality, both advertise natural, interruptible speech, Sable via full-duplex audio and Supersonik via its synthetic voice and avatar layer. Neither publishes latency or user-satisfaction data a buyer could compare, which is worth asking both vendors for in a pilot.

Pricing: two flavors of "talk to sales"

Here the two competitors converge completely, and not in the buyer's favor.

Sable publishes nothing: no pricing page, no tiers, no billing metric, and no reported contract figures from procurement platforms either. Buying means the contact form, the waitlist, and a custom enterprise deal on Sable's timeline.

Supersonik at least has a pricing page, but it contains no prices: it is a consultation form asking for your name, work email, company size, and headquarters country, after which "pricing tailored to your goals" is worked out with you. The AWS Marketplace route is private offers only. No credible third-party figures for either vendor have surfaced as of August 2026.

The practical consequence is the same in both cases: you cannot budget, compare, or build a business case without entering a sales cycle first. For enterprises with procurement teams that expect custom quoting, that is business as usual. For a team that wants to pilot something next month, it is the single biggest reason to look at a third option.

Proof: elite deployments, quantified stories, zero reviews

Both vendors have real proof, and both make you take it on their terms.

Sable's proof is who runs it. Notion and Decagon are discerning, product-led companies, and unnamed "large public companies" plus a 150+ waitlist round out the picture. But every one of those claims arrives via Sable's own PR and its investors; there are no third-party reviews and no published conversion metrics from any deployment.

Supersonik's proof is what its deployments did. More than 250 Salesforce SDRs enabled across three-plus regions and 80,000+ HubSpot customers reached are unusually concrete numbers for this category, published with named customers and dates. Earlier logos include Brevo, Cornerstone, Lemlist, Holded, and Lodgify. Still, these are vendor-published stories, not independent reviews: like Sable, Supersonik has no G2, Capterra, or Product Hunt presence as of August 2026.

So the honest summary is symmetric. Sable offers deeper-brand references with fewer numbers; Supersonik offers more numbers with a shorter enterprise reference list. Neither gives a buyer anything independently browsable.

When Sable wins, when Supersonik wins

Pick Sable if you want one AI employee across the entire customer lifecycle, including post-sale onboarding, partner certification, and internal training, if ISO 42001 and its broader compliance stack matter to your security review, and if you are comfortable being early: joining a waitlist, negotiating a custom deal, and betting on the strongest-funded team in the category before its public launch.

Pick Supersonik if global language coverage is decisive (70+ languages is the widest published range in this market), if you want avatars and cross-session memory that are already shipped and dated, if quantified stories at Salesforce and HubSpot map to your scale, and if a conventional enterprise evaluation, demo first and quote later, fits how you buy.

Either way, go in with questions neither vendor answers publicly: what will it cost, what do sessions convert at, and what do existing customers say when the vendor is not curating the answer.

The third option: a live AI demo agent you can price today

This is where we step in, clearly labeled as a competitor. Naoma is a full-cycle AI account executive for inbound: the agent runs discovery, then delivers a live demo adapted to the buyer, combining slides with your real product driven live in a browser session and branching journeys on higher plans, handles objections, qualifies, and books the meeting or routes straight to signup and checkout, with CRM write-back. It speaks 33 languages, auto-detected and switchable mid-demo, ships best-in-class realistic avatars, branded mascots, and animated avatars — custom builds included — added prospect memory and account enrichment in August 2026, and includes the high-converting website widget with a built-in chat bot on every plan.

The contrast with both vendors above is the buying experience. Pricing is published, from $299/mo, on the pricing page, and billing is engagement-based: a demo becomes chargeable only after 3 minutes of engagement, and bounces are free. You can model your funnel in the ROI calculator before speaking to anyone. Proof is public too: Naoma has conducted over 50,000 AI demos, and in the AiSDR case study, 53% of demos ran past 3 minutes, the average conversation hit 7 minutes 50 seconds, 21% of demos produced a qualified lead, and 6% ended in a booked meeting, alongside a 4.9 on G2 and a 5.0 on Product Hunt. To be equally transparent about gaps: Naoma is GDPR compliant with SOC 2 in progress, and self-serve purchase with a free trial arrives in September 2026, so today plans start with a quote request.
