About
BySix is a Lisbon-area generative-AI development firm building custom agents, document and recruitment assistants and scheduling systems for business operations, with offices in Porto and São Paulo.
Who They Work With
Product and operations teams buying a first generative-AI agent wired into Jira, Slack, Shopify or an ATS at a fixed weekly price.
Based on 5 client engagements with a source URL · researched 3 Sept 2026
Our Take
Five named generative-AI builds are published, and the one that reads as fully live is Gizzmo's store publisher: it watches a Slack channel, pulls supplier files from Google Drive, checks SKUs against the ERP and pushes finished Shopify listings, with a 96% cut in listing turnaround and an 18% keyword-ranking lift reported.
The two Trimble agents (a product-owner agent drafting 70% of new user stories from a RAG index over Jira, Notion, Confluence and Slack, and a support agent that auto-labels tickets) are both described as still in rollout, and the Fullsight CV writer as early rollout, so most of the headline percentages sit on systems the firm itself says are not finished.
The Transporeon slot-booking platform is a different kind of evidence—a logistics product BySix's team has engineered and maintained over years, with an auto-booking module added on top—which reads as product staffing rather than an AI engagement.
The weaker fit is buyers who need model-level detail or a named ML team: the studies list integrations and outcomes, not models, and the team page names a CEO, a head of HR and an engagement manager.
Key strengths
- Published fixed weekly pricing: Launch Agent at €3,000/week (live in six weeks or less), Scale Suite at €6,000/week, Enterprise Program at €10,000/week, with add-ons priced per integration
- Every published AI study names the client and the systems wired in—Jira, Confluence, Slack, Google Chat, Shopify, an ATS, an ERP
- Three offices with street addresses (Algés, Porto, São Paulo) and a 70-plus headcount put delivery capacity above boutique scale
Good to know
- Two of the five AI studies state the rollout is still in progress—ask which systems are in production today and who measured the 52% and 70% figures
- No engineer, ML lead or architect is named anywhere on the site—ask who would staff your build and what they have shipped
- The insights section is a high-volume stream of SEO-style posts (six between 18 August and 3 September 2026)—treat it as marketing, not engineering writing
