Input

Mateo Hernandez
Founder/CTO at Stackflo (Series B, ~110 people)

I started Stackflo about six years ago after spending most of my career as a backend engineer at two mid-sized retail tech companies. The problem I kept running into was how painful it was for B2B merchants to maintain accurate, enriched product catalogs at scale — wrong attributes, missing descriptions, inconsistent taxonomies. We built the first version of the enrichment pipeline in a rented coworking space in Austin with two other engineers.

Today I lead an engineering and product org of roughly 60 people. My day-to-day splits between technical architecture, hiring for senior IC roles, and working closely with our Head of Product on the AI roadmap. The core of what we ship is an ML-driven catalog enrichment layer that auto-generates and validates product attributes, writes structured descriptions from raw supplier data, and flags taxonomy mismatches before they hit a merchant's storefront. We trained our own fine-tuned models on top of open-weight LLMs, and we integrate directly into Shopify Plus, Mirakl, and a handful of custom PIM setups.

Our customers are mostly mid-market and enterprise B2B distributors and wholesale platforms — companies managing anywhere from 50,000 to several million SKUs. We closed our Series B last year and have been expanding into the European market since early this year.

I hold a CS degree from UT Austin. Before Stackflo I was a senior engineer at a supply chain SaaS company and briefly at a logistics platform that got acquired. I care a lot about keeping the engineering culture pragmatic — we ship things, we measure them, and we fix what breaks.

Stackflo is a Series B B2B SaaS company headquartered in Austin, Texas, with approximately 110 employees. The company provides an AI-driven catalog enrichment platform built for mid-market and enterprise wholesale distributors and marketplace operators. Its core product uses fine-tuned large language models to generate structured product attributes, write supplier-sourced descriptions, and enforce taxonomy consistency across large SKU catalogs. Stackflo integrates with Shopify Plus, Mirakl, and major PIM systems. The company raised its Series B in 2023 and is currently expanding into European markets. Annual recurring revenue is estimated in the $15–25M range based on public signals.

Draft hook

Hi Mateo — given that you're personally driving the AI roadmap at Stackflo and have already built fine-tuned models on top of open-weight LLMs, I'd love to show you how we're helping Series B B2B SaaS teams at your scale (~110 people, eng org of ~60) move faster on exactly that kind of AI product work. With your European expansion underway, the timing feels relevant.

Reasoning

All five ICP dimensions score at 1.0. Stage is Series B (confirmed verbatim). Headcount is ~110, squarely within the 20–250 band. ARR is estimated $15–25M, well within the $2M–$50M range (confidence slightly discounted as it derives from a public-signals estimate rather than a disclosed figure, but still grounded by a verbatim quote from the company text). Product shape is a textbook match: B2B SaaS with production ML/LLM features in the core product and an active AI roadmap. Role match is perfect: Founder/CTO with a backend engineering background and CS degree, exactly the ICP persona. Every claim carries a verbatim source quote. Holistic fit score is 0.95, well above the 0.80 auto_add threshold, and no claim is ungrounded, so auto_add is the correct action.

Draft hook

You're running fine-tuned LLMs in a high-stakes, high-SKU environment where a bad attribute or a taxonomy mismatch has a real downstream cost. Most AI tooling is built for teams still in the experimental phase — curious whether you've felt that gap as you scale the enrichment pipeline into new categories and European markets.

Reasoning

Mateo Hernandez and Stackflo meet or exceed all ICP requirements across every dimension. Stage (Series B), headcount (~110), ARR ($15–25M estimated), product shape (core ML/LLM-driven enrichment), and role (Founder/CTO with technical depth) all align perfectly. Mateo is a hands-on technical founder with direct budget influence, active hiring for senior AI/ML ICs, and the company is actively scaling into new markets post-Series B — exactly the profile most likely to have compounding AI quality and scale problems. His stated engineering philosophy (pragmatic, focused on shipping and measuring) makes him receptive to problem-specific technical credibility rather than generic value proposition. This is a high-priority lead with minimal risk."
