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 quality-gated credits from EUR 29/month.","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 — from EUR 29/month, self-serve.\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 |\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 | EUR 29/mo (29 credits) or EUR 79/mo (79 credits) |\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 — only interviews scoring 3+ bill |\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- **Quality-gated credits.** Only conversations scoring 3+ consume credits. Abandoned and low-effort responses do not bill you. Neither Strella nor Outset offers this.\n- **Transparent pricing.** EUR 29/month (Insights, 29 credits) or EUR 79/month (Interviews, 79 credits). Text interviews cost 1 credit, voice 3. Ten free credits at signup, cancel monthly.\n- **[Recruit from your own product](/docs/recruiting-from-your-product)**, import your list, and run [GDPR-compliant research](/docs/gdpr-compliant-ai-user-research).\n\n**The cost comparison, concretely:** a 25-voice-interview study on Koji consumes 75 credits — roughly EUR 75 on top of a EUR 29 plan. 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, and want to prove AI-moderated research works for your team before it becomes a budget line.
