When three Lithuanian founders turned a weekend project into an AI platform for small and mid-sized businesses (SMBs), few could have predicted the journey ahead. But as of June 2025, Sintra has raised $17 million in a seed round and is scaling fast — a story of product vision, strategic positioning, and Baltic ambition.
Origins: a garage-project with global ambition
Sintra’s story begins in Vilnius, Lithuania. Founded in 2023 by Chris Sidlauskas, Rokas Judickas and Vasaris Kaveckas, the company took shape out of a marketing-agency background where the founders had already cut their teeth helping small businesses.
The pivot came when the founders recognised a gap: many SMBs lacked affordable access to skilled support for marketing, social-media, operations, recruiting and customer support. They decided to treat AI not just as automation, but as a teammate: a set of role-specific “helpers” that integrate directly with everyday tools (Gmail, Google Calendar, Facebook, Instagram, LinkedIn) and align with real business workflows.
This framing—AI assistants rather than generic automation—helped differentiate Sintra in a crowded AI marketplace. The founders speak of building an “AI-business-in-the-box” for SMBs — meaning: fast to deploy, simple to use, meaningful impact.
Momentum: early traction and product composition
By June 2025, Sintra reported serving over 40,000 paying customers across more than 100 countries, with annual recurring revenue (ARR) estimates reaching around $12 million.
Their product offers multiple “agents” — for example, a social-media assistant, a customer-support agent, a recruiting assistant, an e-commerce helper. These agents live on top of a central “Brain AI” intelligence layer which holds business-specific context and allows the agents to act autonomously or with minimal supervision.
Crucially, integration with popular platforms and low-friction onboarding helped SMBs adopt the product quickly. One key metric: after the public launch version 2.0 (May 2024), Sintra reportedly reached €877 k (~$950 k) ARR in just 57 days.
The funding round: $17M seed and strategic backing
On June 10, 2025, Sintra announced a seed funding round of $17 million, led by venture capital firm Earlybird VC. Other participants included Inovo, Practica Capital and angel investors such as Mantas Mikuckas (known for his role at Vinted) and Mati Staniszewski.
According to the company, the new capital will be used to: expand engineering and product teams, deepen the Brain AI layer, integrate with more platforms, grow marketing globally, and accelerate SMB-customer acquisition.
