What they're building
Central AI platform (agent runtime, tool and data layer, model gateway, evaluation and observability) strong signal
Today: "AI-powered digital data company providing real-time market intelligence" (site description)
Roles: Backend Engineer with AI Experience · Senior Backend Engineer - AI platform · AI Engineer (Prague)
Requirements mention: LangGraph · LangChain · LLMOps · semantic caching · model routing · RAG systems · MCP servers · AI agent architectures
Inference: three R&D postings in Tel Aviv and Prague describe one company-wide platform for building AI features. This suggests Similarweb's AI products and internal tools will move onto a shared runtime and model gateway rather than each team building its own.
Customer-facing AI product: an AI-native platform and AI Studio with an AI agent, answers, reports and dashboards strong signal
Today: "Put Similarweb's digital insights to work in a click with our AI-powered experts" (site)
Roles: Senior Product Manager, AI-Native Platform · Agent Platform Engineer · AI Engineer (Tel Aviv-Yafo) · Director of Product Management -Sales Intelligence · Product Designer - Maternity Leave · Senior Full Stack Developer (Backend Oriented) · Senior Full Stack Developer
Requirements mention: AI-native platform · agent or workflow automation products · prototype with AI tools · evaluating LLM performance · AI Studio · agentic flows · AI product delivery
Inference: Similarweb is putting an AI agent in front of its data so users can go from a question to a report or dashboard. The postings use two names ("AI-native platform" and "AI Studio") and do not say whether they are the same product.
Search and Ads Intelligence: customer-facing SEO, AEO/GEO and paid media expertise strong signal
Today: "Use our SEO and AEO tools to grow your visibility and rank where it counts" (site)
Requirements mention: AEO · GEO · Paid Search · Paid Social · Programmatic Display · structured data · entity optimization
Inference: four Product-department strategist and consultant roles in New York and Burlington (two of them titled Solution Consultant) point to adding expert, customer-facing support around the existing SEO and AEO product, rather than launching a new one.
Retail Intelligence (classifying and matching product data across retailers and marketplaces) moderate signal
Today: Named in two Tel Aviv R&D postings; not described on the fetched site pages
Roles: Data Analyst · Data Engineer – Applied ML · SMB Customer Success Manager - Retail/E-commerce
Requirements mention: taxonomies · entity resolution · text classification · product/e-commerce data · labeling · data crawling
Inference: a retail data product that uses LLMs and ML to classify and match product data across sources. A Prague customer success role says a team is being built for e-commerce price intelligence following an acquisition.
Investor Solutions (alternative data for investment research) moderate signal
Today: "Similarweb's Investor Solutions products" (posting); investors are not mentioned on the fetched site pages
Requirements mention: alternative data · backtesting workflows · factor research · PE/VC · due diligence · Capital Markets
Inference: a product and account effort aimed at investment firms and consultancies, with roles in New York, London and Singapore.
AI & LLM data partnerships (supplying Similarweb data to AI companies) moderate signal
Today: "Your Must-Have Data Partner To Win In The AI Era" (site)
Roles: Strategic Account Executive - AI & LLM Partnerships · Senior Field Marketing Manager - AI & LLM Partnerships
Requirements mention: Large Language Models (LLM) · partner ecosystems · GSIs · partnerships marketing
Inference: a dedicated sales and marketing effort to license Similarweb data to AI and LLM companies.
