AWS for Startups Sofia
12 March 2026

Today, 85% of the startups on the Forbes 2025 AI 50 run on AWS. They choose AWS to build faster, optimize costs, and innovate at scale - with the security, reliability, and breadth of services needed to move from experiment to production. From cloud fundamentals to modern data and AI capabilities, AWS helps teams ship with confidence and keep momentum as they grow.

On 12 March 2026, Several Clouds and AWS will bring this experience to Sofia with an exclusive, one-day event at Hilton Sofia for founders, C-level leaders, and business decision-makers building or refining their cloud strategy (on AWS or elsewhere).

Attendees will:
- Get key takeaways from AWS re:Invent 2025, including Agentic AI, Amazon Bedrock, AgentCore, and Kiro.

- Hear from VC investors on 2026 fundraising: what matters, which metrics win, and how to stand out.

- Explore the programs AWS and Several Clouds offer for startups - such as credits, partner support, and go-to-market resources - and how to apply them at each stage of growth.

- Learn AI Financial Management & cost control to manage cloud and AI spend while scaling compute-intensive workloads.

- Join a customer fireside chat with a leading Bulgarian startup on scaling on AWS, cost management, and production AI.

Note: Attendance is subject to approval and capacity.
With a limited number of seats available, we’ll prioritise AWS Startup customers, AWS Technology Partners, and a select set of organisations aligned with the event focus. Thank you for your understanding if we’re unable to confirm every registration!
