Company profile
researched Sep 2026Heatseeker (incorporated as Heatseeker Technologies Pty Ltd) operates a market research platform built around observed buyer behavior rather than survey responses. The product has two components: always-on synthetic personas and panels generated from a customer's own first-party data, which can answer questions in seconds or be queried at the scale of hundreds of personas for a quantified read; and live in-market experiments, in which message, concept, creative or product variants are run as advertising to real audiences on Meta, LinkedIn and TikTok, either under the client's brand or a lookalike ("stealth") brand. Click and engagement data from those campaigns is tested for statistical significance and used to rank variants and to calibrate the personas.
The platform packages common research questions as experiment templates spanning discovery, positioning, validation and optimization, including segment, value proposition, concept, messaging, jobs-to-be-done, benefit, product demand, pain-point, feature, buying driver and image/video/full creative tests. A workflow guides users from stating a decision in plain language, through AI-assisted audience and variant design drawn from the client's site and data, to a launch checklist, live run and a ranked, significance-tested result. Client data is consolidated in what the company calls the Customer Context Layer, refreshed weekly or daily depending on plan, which feeds both engines; the company states it does not use this data to train third-party models. Heatseeker also exposes the customer view to assistants such as Claude, ChatGPT and Microsoft Copilot over MCP. The site lists SOC 2 Type II, GDPR compliance, AES-256 encryption, SAML SSO and US, EU and AU data residency.
At launch the product was positioned toward founders and growth marketers at B2B startups as "growth-hacking-as-a-service," automating social-media-based idea validation that previously required in-house data science skills, and scanning competitor websites and online review sentiment. Positioning has since shifted toward enterprise marketing, insights and product leadership.
Founding story
Heatseeker.ai was co-founded in 2023 in Sydney by Kate O'Keeffe and Fiona Triaca, who set out to read markets in real time from actual customer interactions rather than stated intent. Rutger Coolen is also named as a co-founder.
Business model
Software platform sold to companies that design and run market experiments and query synthetic personas; the site references plan tiers (data refreshed weekly or daily by plan) and a pricing page, with sales initiated through a 30-minute demo.
Subscription-style platform access with plan-based service levels, per the company's pricing and plan references.
Traction
Company materials cite customers including L'Oréal, DoorDash, Hearst and KPMG and testimonials from marketing executives at HelloFresh, Wamo Bank and L'Oréal; press reported more than a dozen enterprise clients across the US, Europe and Australia as of May 2025. The company won L'Oréal's beauty tech startup program, which the program reopened after the win.
Latest developments
Heatseeker won L'Oréal's beauty tech startup program, after which the program was reopened, as reported by Startup Daily in May 2026. The current platform adds the Customer Context Layer, synthetic panels and market simulations, MCP access from Claude, ChatGPT and Copilot, and live experiments on TikTok alongside Meta and LinkedIn.
▸Full profile — market position, technology, go-to-market, geography, history, risks & controversies
Market position
Positions itself against traditional surveys, focus groups and paid panels, and against synthetic research tools that validate themselves against survey data rather than observed purchasing behavior. Capital Brief framed the company as targeting the roughly US$110 billion market research industry.
Combines synthetic prediction with live in-market validation, calibrating persona output against actual buyer behavior; claims up to 95% correlation between calibrated predictions and real buying behavior versus 20-30% for standard surveys, and 20-30x faster turnaround than traditional research. Auditability features include disclosed sample sizes, audience definitions, significance and confidence intervals.
Technology
AI-generated synthetic personas and panels grounded in client first-party data (CRM, transactions, performance marketing and research inputs) aggregated in a Customer Context Layer; live advertising experiments on Meta, LinkedIn and TikTok measuring revealed preference; statistical significance testing, sample- and effect-size-based confidence scoring, traceable experiment IDs, and MCP connectivity to Claude, ChatGPT and Copilot.
Go-to-market
Direct sales led by demo bookings from the website, supported by press coverage, published articles and corporate innovation programs. The company runs a dual-continent model with product development in Australia and go-to-market operations in the United States.
Initially founders and growth marketers at B2B startups; currently CMOs and marketing leadership, brand and product marketing, performance marketing, product and innovation teams, and insights leads at enterprises. Capital Brief reported more than a dozen enterprise clients across the US, Europe and Australia, including banks and health insurers.
Geography
Australian product development with US go-to-market operations; described as Sydney-based in press coverage. Customers span the US, Europe and Australia, and the platform offers US, EU and AU data residency.
History
Founded in 2023; the alpha version of the testing platform launched in April 2024, initially serving founders and growth marketers at B2B startups in the US and Australian markets and with plans for an "AI User" feature built on synthetic data. A pre-seed round was in progress during 2024, and a US$1.5 million pre-seed round led by Capital F was announced in May 2025, earmarked for a Synthetic Experiments capability. By 2026 the product had broadened into an enterprise platform combining synthetic personas with live experiments.
Risks & controversies
Performance claims such as up to 95% predictive correlation and 20-30x speed advantage are company-stated and not independently verified in the available coverage. The approach depends on client first-party data quality and on continued access to advertising platforms including Meta, LinkedIn and TikTok.
