Proofs AI Agents generate code for customized Proof-of-Concepts (PoCs) and full-stack applications, enabling sales engineering teams to build working software demonstrations in hours instead of weeks. Our platform dramatically cuts PoC development costs from tens of thousands to just hundreds of dollars while shortening sales cycles and improving conversion rates.
The Problem We Solve: Building tailored PoCs traditionally takes weeks to months and $10K-$100K+ in engineering time per prospect. This bottleneck slows deals, inflates customer acquisition costs, and wastes scarce technical talent on demo-ware that serves only a fraction of prospects.
Our Solution: Proofs deploys autonomous AI agents that assemble fully working, brand-aligned PoCs in hours. The platform ingests your prospects preferred tech stack, APIs, and data, then produces deploy-ready code complete with customized configurations, branding, copy, data, and use-case flows.
Bring Your Own Tech Stack: Our platform supports virtually any modern tech stack. Examples include:
- Modern frameworks (React, Next.js, FastAPI, Streamlit)
- Data platforms (Snowflake, Supabase, PostgreSQL)
- CMS solutions (Contentful, Contenstack, Akeneo)
- E-commerce (Shopware, NextJS Commerce)
- Full-stack capabilities (front-end interfaces, back-end functionality, APIs, infrastructure)
Our mission: To build what your prospects actually want to buy.
Let your prospects experience your solution in their environment before signing a contract. Proofs turns sales conversations into immediate product experiences that resonate with buyers.
