Stone's Growth Ops team is hiring a senior PM to make Lucy, its AI sales agent, qualify leads across banking, credit, Tap, Link and Pix QR instead of only the card machine. But stone.com.br strips that intent out before Lucy sees it: the Link de Pagamento, TapStone, Conta PJ, Capital de Giro and Pix e Boleto pages all open WhatsApp with the same "Olá, você pode me ajudar?" and send their "Adquira" button to the same card-machine page. A business owner who was reading about working capital at 1.75% a month arrives looking exactly like one who wants a card machine, and Lucy has to guess.
First action
Change the WhatsApp message on the Capital de Giro page and compare its leads for a week.

Why it works
Give every product and segment page its own prefilled WhatsApp message and a short reference code (for example "Quero saber do Capital de Giro [CG-SITE]"), and pass the same code as a parameter to /adquira and to the app links. Have Lucy read the code first and open with the product the visitor chose, then qualify the other needs. Store the code on the CRM lead so Growth Analytics can measure conversion by page. Test against today's generic message with a control group, as the role requires.
Lucy starts every conversation one question ahead, completion and conversion rise, and the multiproduct goal gets real data from day one. It is a few hours of work on the site for the most important AI project in the funnel.

Evidence
- HiringProduct Manager Sênior, IA Conversacional e Growth (São Paulo, posted October 15, 2026): Growth Ops runs "the revenue infrastructure of Stone's digital channels (routing, offer, sale and measurement)" for Inside Sales, Autocred, App Stone and App Ton. Lucy, "Stone's commercial AI", handles the entry conversation: "every lead that arrives through Site, App and WhatsApp goes through her", scores it and hands it to the highest-value channel. "The next evolution is to make qualification multiproduct, identifying in the conversation the need for banking, credit, Tap, Link and Pix QR, and not only the card machine." The PM runs A/B tests "always with a control group" and tracks completion rate, time to first contact and conversion (translated from Portuguese).Source
- Your websitestone.com.br product pages (checked October 21, 2026): Link de Pagamento, TapStone, Conta PJ, Capital de Giro and Pix e Boleto all use the same WhatsApp link with the same prefilled message, "Olá, você pode me ajudar?" ("Hi, can you help me?"), and the same "/adquira" button, so the first message never says which product the visitor was reading about.Source
- Your websiteThe "/adquira" page every product page links to is titled "Peça sua Maquininha e Abra sua Conta PJ" and leads with a card-machine offer ("Débito a partir de 0,74% | Crédito a partir de 2,99%", free shipping, "Parcelamento em até 21x"); the form asks only name, mobile and email, then "Continuar pelo WhatsApp". Outside hours it shows "Estamos fora do horário de atendimento" (Monday to Friday 6h-24h, weekends and holidays 7h-19h). It counts "4.680.875 empreendedores".Source
- Your websiteCredit pages: "CAPITAL DE GIRO COM TAXAS A PARTIR DE 1,75% AO MÊS", government-backed lines (FGI PEAC, BNDES and Sebrae) and "Pix e Boleto no Crédito"; TapStone sells "with the same rates as your Stone card machine" on Android and iPhone.Source
