## About this market
Software and B2B buyers in Lisbon get a page split between building the product and getting it found. Twistag is the strongest builder: a recommendation engine for the event app Joyraft reporting 10,000 weekly active users and 40% of clicks on recommended events, plus agentic platform work for the speaker agency PepTalk. BySix's product-owner agent for Trimble auto-drafts more than 70% of user stories, which is AI aimed at the software team rather than the end user. Altar.io has built product for startups and scale-ups from Lisbon since 2015. AISO Hub covers the other half—AI-search visibility for the comparison and eligibility prompts B2B buyers now ask an assistant instead of a search engine. Techrivo sits apart from both, selling technical due diligence and compliance engineering to the financial-software end of the market.

The two builders publish bands around €45-85 an hour, which is roughly half what the equivalent London bench charges and the reason a lot of European SaaS engineering has moved here. That gap is real but it is not free: ask where the engineers sit, how the timezone overlap works against your standups, and who owns the model weights and prompts when the engagement ends.
