Cresva replaces traditional analytics dashboards with seven specialized AI agents that autonomously analyze data, make strategic decisions, and execute marketing operations. Cresva What does Cresva do? And why is now the time for it to exist? Cresva is an AI Marketing Workforce - seven specialized AI agents that autonomously run marketing operations for ecommerce brands, from attribution analysis to budget allocation to creative strategy. Unlike dashboards that show you data, Cresva's agents analyze, decide, and act - sharing memory across every decision so they compound in accuracy over time. Brands on the platform have seen forecast accuracy jump from 78% to 91%, replacing fragmented tool stacks with a single intelligent system. Now’s a good time for Cresva to exist because performance marketing teams are currently drowning in fragmented data dashboards and require autonomous, decision-making tools to efficiently manage increasingly complex ad campaigns. What is your traction to date? How many people does Cresva reach? Currently serving pilot brands in India and the UK managing $500K+ in annual ad spend. Platform targets the 100,000+ ecommerce brands globally running significant paid media budgets across Meta, Google, and TikTok. Who does your Cresva serve? What’s exciting about your users and customers? Ecommerce brands and performance marketing agencies spending $500K+ annually on digital ads who are drowning in dashboards but starving for decisions. Specifically, marketing leads and founders who need senior-level marketing intelligence without the $150K/year analyst headcount. What technologies were used in the making of Cresva? And why did you choose ones most essential to your tech stack? To build Cresva's autonomous multi-agent architecture, the team utilized a modern frontend stack featuring TypeScript, Next.js, and React, backed by a robust PostgreSQL database. Essential to its core functionality, Cresva leverages both OpenAI and Anthropic LLMs to power its shared memory framework and custom attribution modeling engine, while directly integrating with Meta, Google, and TikTok Ads APIs alongside Slack for seamless operational communication. What is the traction to date for Cresva? Cresva is actively deployed with pilot brands across the Indian and UK markets, processing real ad spend data via live API integrations with major ad networks like Meta, Google, and TikTok. Founded by an experienced marketer who has managed over $10M in ad spend, the platform is already demonstrating tangible results, notably improving forecast accuracy for pilot users from 78% to 91% and successfully validating its $299–$1,999 monthly pricing tiers. Cresva scored a 59 proof of usefulness score (https://proofofusefulness.com/report/cresva) Cresva scored a 59 proof of usefulness score (https://proofofusefulness.com/report/cresva) https://proofofusefulness.com/report/cresva What excites you about Cresva's potential usefulness? * Most marketing "AI tools" are glorified dashboards with a chatbot bolted on. Cresva's agents don't just show you data - they think, decide, and act. What excites me most is the compound learning moat: every decision each agent makes feeds back into shared memory, so the system gets smarter with every dollar spent. This means a brand using Cresva for 6 months has a fundamentally different (better) AI than one that just signed up. That's not a feature - that's a flywheel that makes marketing intelligence accessible to brands that could never afford a senior analytics team.
