Alibaba's SPAR B2B sales agent on 1688 raises conversion 15.8% in live test

Alibaba has published SPAR, a self-evolving sales agent for B2B outreach on its 1688 platform, which Elvis Saravia reports lifted conversion 15.8% and high-intent merchant growth 35.8% in a live A/B test across more than 200,000 merchants.

SPAR improves without updating model weights, using per-merchant episodic memory and a shared playbook of testable selling strategies.

Before changing the playbook, SPAR attributes each lost deal to either a bad strategy or an outside factor. Domain experts rated its sales quality 4.62 out of 5, the highest of the methods tested, according to the same report.
