Investor insight
At Series A/B, engineering acceleration is a trajectory signal rather than a discovery signal. A hiring burst or platform buildout often precedes the next round. Institutional investors use these signals to prioritize outreach and refine conviction before a lead term sheet. Infrastructure buildout is classic Series A behavior: the core product works, and the team is building the platform around it. This pattern requires capital and reflects confidence in the product direction.
