Bottleneck Marketing

Bottleneck Marketing is a paid media and marketing analytics agency founded by Plínio Marques de Siqueira, built for startups that are already spending on ads but cannot tell which spend is actually working. The agency's pitch is the pairing most paid media shops skip: channel execution and measurement together. Campaigns across paid search and paid social are run alongside conversion tracking setup and marketing analytics, so every scaling decision is tied back to attribution a founder can actually trust. Services cover paid search and paid social management, campaign strategy and scaling, conversion tracking setup, and marketing analytics and reporting. The approach is analytics-first: rather than adding channels for their own sake, the team focuses on finding and removing the specific bottleneck holding growth back — whether that is a broken tracking setup, a mispriced bid strategy, or a channel that looks good on last-click but fails under cleaner measurement. Hands-on founder involvement means clients work directly with senior operators rather than being handed off to a rotating account team. Bottleneck Marketing is best suited to early and growth-stage startups that are already spending on ads and want a partner who can both run the campaigns and fix the attribution behind them — founders who cannot tell which spend is working come here for clean measurement first, then scale the channels the data proves out.
