Strella uses seat-based per-study contracts around $10K-$25K, bundles a 3M+ participant panel via User Interviews, is text-first with video escalation, and produces multi-level theme hierarchies. Outset is priced near $20K per seat per year with usage billing, supports text, voice, and video in 40+ languages, and requires bring-your-own participants. Neither offers self-serve signup or structured quantitative question types. Koji provides AI-moderated voice and chat interviews with six structured question types, automatic thematic analysis, and a quality gate, as low as EUR 1 per qualified interview (EUR 3 per qualified voice interview), self-serve with 10 free credits and no subscription.","content":"\n# Strella vs Outset (2026): AI Research Platforms Compared on Price, Panel, and Depth\n\n**Short answer:** Choose **Strella** if you run discrete research projects on a sprint cadence, need participants recruited for you, and can budget per study. Choose **Outset** if you have a standing research function, bring your own participants, and want text, voice, and video moderation across 40+ languages under a seat licence. Choose **[Koji](https://www.koji.so)** if you want AI-moderated interviews with six structured question types and automatic analysis without a five-figure commitment: interviews as low as EUR 1 per qualified interview and EUR 3 per qualified voice interview, self-serve with 10 free credits, then pay as you go with no subscription.\n\nBoth platforms do the same fundamental thing: an AI moderator conducts in-depth interviews, probes with real follow-ups, and synthesizes themes automatically. The differences that actually change your decision are how they are *bought*, whether recruitment is included, and what kind of data you get out.\n\n---\n\n## The context: why this category exploded\n\nResearch teams did not adopt AI moderation because it was novel. They adopted it because the unit economics collapsed. **AI-moderated qualitative interviews now run roughly $8-$15 per completed interview against $150-$300 for a human-moderated equivalent.**\n\nAdoption followed immediately: **about 81% of dedicated research teams, 73% of UX teams (up from 38% in 2024), and 67% of product management teams** now use AI-moderated interviews, and **72% of insights buyers use generative AI somewhere in the research process, up from 23% in 2023**. Inside a market research industry projected at roughly **$150 billion in 2026**, AI-native qualitative is the fastest-moving segment.\n\nStrella and Outset are two credible answers to that shift, aimed at different buyers.\n\n---\n\n## Strella vs Outset: side-by-side\n\n| | **Strella** | **Outset** | **Koji** |\n|---|---|---|---|\n| Funding | $14M Series A (Bessemer, Decibel, Bain Future Back, 645Ventures) | $30M Series B (Radical Ventures, M12) | Bootstrapped, self-serve |\n| Traction signal | $1.6M ARR in first year of monetization, 150%+ net dollar retention | Reported 8x business growth pre-Series B | Self-serve, no contract required |\n| Modalities | Text-first, escalates to video | Text, voice, video | Voice + chat |\n| Languages | Multilingual | 40+ | 40+ |\n| Built-in panel | Yes — 3M+ via User Interviews partnership | No — bring your own | Bring your own, recruit in-product, or built-in panel recruitment quoted in credits |\n| Structured question types | Primarily open-ended | Primarily open-ended | 6 types in one study |\n| Automatic synthesis | Yes — 2-4 levels of follow-up themes | Yes — summaries, themes, quotes | Yes + transcript chat |\n| Highlight reels | Yes | Yes | One-click reports |\n| Pricing model | Seat-based; ~$10K-$25K+ per study engagement | ~$20K/seat/year + usage-based billing | From EUR 1 per qualified interview, EUR 3 voice; pay as you go, no subscription |\n| Free access | 14-day trial, no free plan | No standard free trial | 10 free credits at signup |\n| Self-serve signup | No | No | Yes |\n| Quality-gated billing | No | No | Yes, a conversation scoring below 3 out of 5 is free |\n\n---\n\n## What Strella actually does\n\nStrella was founded in 2023 and raised a **$14 million Series A led by Bessemer Venture Partners**, with Decibel Partners, Bain Future Back Ventures, MVP Ventures, and 645Ventures participating. Bessemer reported it reached **$1.6M ARR in its first year of monetization with over 150% net dollar retention** on its first renewal cohort — genuinely strong numbers that indicate teams expand usage after they start.\n\n**Where Strella is strong:**\n\n- **Synthesis depth.** Strella clusters themes across conversations and typically surfaces two to four levels of follow-up themes rather than a flat list. If your complaint about AI analysis is that it produces shallow bullet points, this is a real differentiator.\n- **Recruitment included.** A partnership with User Interviews puts a 3M+ participant panel inside the platform, so sourcing is not a separate workflow.\n- **Sprint-shaped.** The product fits teams running one- to two-week research cycles where tactical validation and fast stakeholder updates matter more than longitudinal programs.\n- **Enterprise proof points.** Reported customers include Amazon, Duolingo, and Chobani.\n- **A real trial.** Strella offers a 14-day free trial — more hands-on evaluation than most enterprise competitors allow.\n\n**The trade-off:** per-study contracts reportedly run **$10,000-$25,000+ per engagement** on seat-based pricing with no free plan. That is workable if research is a funded project line; it is prohibitive if you want to ask customers a question next Tuesday.\n\n## What Outset actually does\n\nOutset raised a **$30M Series B led by Radical Ventures with M12 (Microsoft's venture arm)**, 8VC, and Y Combinator participating, after reporting **more than 8x growth**. In 2026 it repositioned toward \"AI-native customer experience management.\"\n\n**Where Outset is strong:**\n\n- **Modality breadth in one study.** Text, voice, and video moderation across **40+ languages**, with adaptive personas that deepen probing as the conversation develops.\n- **Usage-based billing.** Charges attach to research questions asked during live interviews, so cost tracks actual volume rather than a fixed project fee.\n- **Security posture.** SOC 2, GDPR adherence, Azure hosting, and a \"never trained on your data\" policy — the documentation a security review asks for.\n- **Highlight reels.** Customizable clip reels that move stakeholders who will not read a report.\n- **No panel you did not ask for.** BYO participants means B2B teams interviewing their own customers are not subsidising consumer panel infrastructure.\n\n**The trade-off:** reported pricing sits near **$20,000 per seat per year** plus usage, nothing is published, and there is no standard free trial. Recruitment is your problem unless you add User Interviews separately.\n\n---\n\n## The head-to-head that matters\n\n**Recruitment: Strella wins.** A bundled 3M+ panel removes the slowest step in qualitative research. Outset makes you solve it yourself.\n\n**Modality: Outset wins.** Text, voice, and video natively across 40+ languages beats Strella's text-first-with-video-escalation model if you need audio or visual data by default.\n\n**Synthesis: Strella has the edge.** Multi-level theme hierarchies are a more sophisticated output than flat summaries with quotes. Both are good; Strella's is deeper.\n\n**Buying model: it depends on your shape.** Strella's per-study pricing suits organisations that fund research as discrete projects. Outset's seat-plus-usage model suits a standing research function running continuously. Pick the one that matches how your finance team thinks, because fighting your own budget structure is a losing move.\n\n**Evaluation: Strella wins narrowly.** A 14-day trial beats no trial.\n\n**Total cost: effectively a tie at a high floor.** Strella at $10K-$25K per engagement and Outset at ~$20K per seat per year land in the same band. Neither is accessible below five figures.\n\n---\n\n## What neither platform solves\n\nStrella and Outset are competing for the same buyer: an organisation where research is a budgeted function with a procurement process. If that is you, pick from the framework above and stop reading.\n\nBut most teams making product decisions are not that buyer. They are a founder validating positioning, a PM running discovery before a roadmap review, a two-person UX team, or an agency delivering for clients on fixed fees. For them, the relevant question is not \"Strella or Outset\" — it is \"can I run rigorous customer interviews at all without a five-figure contract.\"\n\n[Koji](https://www.koji.so) is built for that question:\n\n- **[AI-moderated voice and chat interviews](/docs/ai-moderated-interviews)** with real-time adaptive probing on an ElevenLabs voice stack, running 24/7 with no scheduling and no moderator bias. See [AI voice interviews](/docs/ai-voice-interviews).\n- **Six structured question types in one study** — open-ended, scale, single choice, multiple choice, ranking, yes/no. This is the substantive capability difference. Strella and Outset are open-ended engines; when you need a number to chart, you run a separate survey. Koji captures the narrative *and* the metric in a single instrument. See [open-ended questions](/docs/open-ended-questions-ai-interviews) and [multiple-choice questions](/docs/multiple-choice-questions-ai-interviews).\n- **[Automatic thematic analysis](/docs/thematic-analysis-guide)** with [AI auto-tagging](/docs/ai-auto-tagging-customer-interviews), plus [chat with your transcripts](/docs/chat-with-interview-transcripts-ai) to interrogate 100 interviews and get a cited answer in seconds.\n- **Customizable AI consultants** tuned to your domain and research goals — an AI product marketer or UX lead that interrogates your insights on demand.\n- **A quality gate.** A conversation that scores below 3 out of 5 is free and never charged. Abandoned and low-effort responses do not bill you. Neither Strella nor Outset offers this.\n- **Transparent pricing.** Interviews start as low as EUR 1 per qualified interview and EUR 3 per qualified voice interview. Start with pay as you go. No subscription needed, and volume pricing and plans are there when you want them. Ten free credits at signup, no card. There is no overage. You pay as you go, and you only ever pay for the conversations that bring insights.\n- **Recruitment, either way.** You do not need your own audience: describe the one you want (market, demographics, role, screening) and approve a live per-respondent quote in credits before launch. If you do have people, [recruit from your own product](/docs/recruiting-from-your-product) or import your list. Either way you can run [GDPR-compliant research](/docs/gdpr-compliant-ai-user-research).\n\n**The cost comparison, concretely:** a 25-voice-interview study on Koji costs about EUR 75, at EUR 3 per qualified voice interview. The same study as a Strella engagement starts around $10,000, and on Outset requires a seat priced near $20,000/year. Even allowing for Strella's included panel, the difference is not incremental.\n\n---\n\n## Which should you choose?\n\n**Strella** if research is project-funded, recruitment is your bottleneck, you want the deepest automatic synthesis available, and $10K+ per study is a normal line item.\n\n**Outset** if you have a continuous research function, your own participants, a need for native video alongside voice and text, and a security review that wants SOC 2 documentation.\n\n**Koji** if you want to start this week, need quantitative and qualitative signal from one study rather than two tools, refuse to pay for a panel you will not use (recruitment is built in and quoted per respondent in credits on the studies where you do need it), and want to prove AI-moderated research works for your team before it becomes a budget line.
