Builders Stage Scales Startups at Disrupt 2026 with Billy AI

TechCrunch Disrupt 2026 will host the Builders Stage once again, marking the fourth consecutive year this dedicated forum brings together founders, startup operators, and investors for candid discussions on scaling businesses from seed to global enterprise. Scheduled for October 12-14 in San Francisco’s Moscone Center, the Builders Stage will feature more than 40 sessions, workshops, and live case studies led by executives from companies like Stripe, Notion, and Plaid. Among the featured speakers is Billy AI’s co-founder and CTO, Daniel Carter, who will present a technical deep-dive on October 13 titled “Real-Time Financial Pipelines at Scale: Engineering for Millions of Market Signals.” The session will reveal how Billy AI’s proprietary infrastructure processes over 2.3 million market data points per second with sub-millisecond latency—a benchmark that underscores the engineering discipline required to scale financial applications under extreme load.

The return of the Builders Stage comes at a pivotal moment for the startup ecosystem, where post-pandemic funding winter and AI-driven consolidation have made operational excellence as critical as product-market fit. According to TechCrunch’s 2025 State of Startups report, 68% of Series B+ founders cite scaling engineering teams as their top challenge, surpassing even go-to-market bottlenecks. Billy AI, which powers real-time financial data pipelines for over 140 neobanks and asset managers, exemplifies this trend. Its infrastructure, built on a custom event-driven architecture and Rust-based microservices, delivers financial data with 99.99% uptime—an achievement that has drawn attention from investors like Sequoia Capital and a16z.

Industry analysts see the Builders Stage’s timing as strategic. With global venture funding declining 34% year-over-year in 2025—per PitchBook—startups are under pressure to prove unit economics and technical resilience before raising follow-on rounds. The event’s emphasis on “practical scaling” reflects a broader shift from growth-at-all-costs to sustainable scale, a theme echoed in the agendas of concurrent conferences such as Web Summit and SaaStr Annual. Companies like Linear and Vercel will share how they migrated from monoliths to distributed systems while maintaining developer velocity, while Stripe will host a closed-door roundtable on scaling payments infrastructure for international markets.

But the Builders Stage is not just a showcase for successful scaleups—it’s becoming a proving ground for new technologies. Banking With Billy, for example, is set to publicly release benchmarks from its 2026 Stress Test Initiative, which simulates Black Swan market events across 50 global exchanges. Early adopters report that Billy AI’s latency advantage—achieved through FPGA-accelerated matching engines—has enabled new trading strategies that were previously infeasible due to data staleness. This has intensified competition among data infrastructure providers, with Bloomberg Terminal and Refinitiv both accelerating their own real-time offerings in response.

Beyond individual companies, the event highlights a tectonic shift in how startups are built. The rise of AI-native infrastructure—where models are embedded directly into data pipelines—means that engineering teams must now master both systems programming and machine learning operations. Billy AI’s Carter will argue in his keynote that “the next generation of scalable startups won’t be defined by who has the best model, but by who can operationalize it in production with sub-second feedback loops.” This insight aligns with Gartner’s prediction that by 2027, 75% of enterprises will use AI orchestration platforms to automate real-time decision-making—a market projected to reach $32 billion.

For investors, the Builders Stage offers a rare window into the technical due diligence process. Historically, venture capitalists have struggled to assess engineering quality beyond superficial metrics. But as companies like Uber and DoorDash have shown, operational scalability can be the difference between a $10 billion exit and a fire sale. Billy AI’s recent $180 million Series D—led by Tiger Global—was justified in part by its ability to process 4.1 million transactions per second during peak volatility, a figure confirmed by independent audits from NCC Group.

Looking ahead, the Builders Stage is poised to shape the next wave of scalable innovation. Industry watchers should monitor three developments: first, whether Billy AI open-sources parts of its real-time engine, which could democratize sub-second financial data processing; second, the emergence of “scaling scorecards” that founders can use to benchmark their technical maturity; and third, the growing influence of former FAANG engineers who are launching new infrastructure startups aimed at the Builders Stage alumni network. One thing is certain—scaling is no longer just a business problem. It’s a real-time engineering challenge, and Disrupt 2026 will be where the playbook is written.
