Short answer: iGrowth and Desorbitante both build B2B acquisition systems that combine inbound and outbound, rather than running one-off campaigns. The key difference is focus: iGrowth is ultra-specialized in scaling B2B SaaS companies (its message is taking a SaaS from 1 to 10 million a year), while Desorbitante runs the acquisition system end to end across a broader range of B2B sectors (technology, finance, industry, professional services, staffing and more), with multi-platform paid media, its own sending infrastructure and an operated CRM. If your company is a SaaS looking for a partner hyper-specialized in that model, iGrowth is a natural choice. If you operate in another B2B vertical or want to outsource the complete acquisition engine, Desorbitante is a better fit.

What does iGrowth do?
iGrowth is a B2B marketing agency based in Barcelona, exclusively specialized in growing B2B SaaS companies in a scalable, predictable way. Its proposition can be summed up as scaling a SaaS from 1 to 10 million a year through complete acquisition, conversion and retention systems, working side by side with the client as an extension of their team. Instead of stopping at standalone ads or content, they implement validated acquisition systems, optimize the funnel through to close and design acquisition offers built for the subscription model.
It is a strong fit if your company is a B2B SaaS and you value a partner that deeply understands the specifics of that model: metrics like CAC, MRR and churn, subscription cycles and the logic of scaling recurring revenue.
What does Desorbitante do?
Desorbitante designs, runs and optimizes B2B customer acquisition systems end to end for Spain and LATAM, across a broad range of sectors. The service covers ICP definition, building verified first-party data with intent signals, coordinated multichannel operation (email, LinkedIn, paid media and calls), managing the sending infrastructure to guarantee deliverability, and native integration with the client’s CRM, with all performance visible on a real-time dashboard.
The model is to run the complete acquisition engine for B2B companies across different verticals, not just SaaS. More than 70 B2B companies have worked with this approach, with response rates around 38% and ROAS cases of up to 30 times in paid media.

When to choose iGrowth?
iGrowth is a better fit if your company is a B2B SaaS and you want a partner ultra-specialized in that specific model. If your priority is scaling recurring revenue and you value an agency that masters the metrics and the specific dynamics of subscription software (activation, retention, expansion), deep specialization is a real advantage over a generalist provider.
When to choose Desorbitante?
Desorbitante is a better fit if your B2B company is not a SaaS, or if you want to outsource the complete acquisition engine with a single team running outbound, paid media and CRM under one strategy. It is the right option when you work in sectors like technology, finance, industry, professional services or staffing, when deliverability control and intent signals matter to you, and when you want to see results on a real-time dashboard instead of receiving monthly reports. If your case is a SaaS, you can see how we handle it in our solution for software and SaaS.
