Key Takeaways
- • Bessemer Venture Partners leads Ampersand's $15M Series A funding round to address enterprise software integration challenges across customer environments.
- • Co-founders Ayan Barua (CEO, former VP of Engineering at G2 and co-founder of Siftery) and Lauren Long (CTO, former Firebase engineer) built Ampersand after six years of firsthand experience with complex CRM and ERP integration work consuming substantial engineering resources.
- • Ampersand's platform enables developers to declare integrations once and have them work across every customer environment at runtime, eliminating the traditional per-customer customization burden that has historically protected legacy systems.
- • The company has achieved a 90% success rate converting proof-of-concept engagements into paying customers, indicating strong product-market fit and enterprise adoption momentum.
- • Ampersand was founded in 2022 and positions itself at the intersection of developer tools and AI agents, addressing the urgent need for scalable integration solutions as AI systems of action gain mainstream adoption.
Summary
Bessemer Venture Partners has led Ampersand's $15M Series A funding round, backing a developer platform designed to solve one of enterprise software's most persistent integration problems. The company was founded in 2022 by Ayan Barua and Lauren Long, both repeat founders with deep experience in developer infrastructure and SaaS ecosystems.
The core problem Ampersand addresses stems from the fragmentation inherent in enterprise software deployments. When software vendors build integrations—such as Salesforce connectors—they typically design against a standardized schema. Upon customer implementation, however, the reality diverges sharply: each customer has customized their CRM or ERP system with different objects, fields, permissions, and configurations. This forces engineering teams to rebuild integrations repeatedly for each customer, with senior engineers often diverted from product roadmaps to handle onboarding and schema management.
Barua, who previously served as VP of Engineering at G2 and co-founded Siftery, witnessed this pattern consume "insane amounts of product engineering time nearly every quarter" across both companies. Long, a former Firebase engineer, brings deep expertise in developer tools and infrastructure. Their thesis was straightforward: declare an integration once in version-controlled code and have it execute reliably across every customer environment at runtime. This approach transforms per-customer integration projects from bespoke consulting work into standardized, maintainable code.
The timing of Ampersand's platform aligns with a broader shift toward AI agents and systems of action. Traditional solutions engineers can navigate custom integrations through manual problem-solving; AI agents cannot. This urgency has accelerated demand for Ampersand's standardized integration layer. The company has already demonstrated strong traction, achieving a 90% success rate of proofs of concept converting to paying customer relationships—a metric that signals robust product-market fit in the enterprise software space. Bessemer's conviction in the company reflects its belief that Ampersand is dissolving the per-customer integration tax that has historically served as a competitive moat for entrenched enterprise systems.
