How to sell to CTOs at Developer tools companies in Spain
CTOs in developer tools companies in Spain are primarily measured on system uptime. They respond to outreach that clearly identifies how a solution can enhance operational efficiency or reduce downtime. Understanding their technical pain points, such as CI/CD pipeline failures or observability gaps, demonstrates relevance and can initiate a conversation.
Written and maintained by the SoloRiff team, who build outbound software and run outbound with it. The figures below are our own: we measured 587 developer tools company domains over public DNS on 2026-09-03. Last updated 2026-09-03.
What actually hurts
- ci/cd pipeline failures
- observability gaps
- resource limitations
- system downtime
The playbook
- 01
Identify CI/CD pain points
Research recent incidents or outages reported by developer tools companies in Spain. Use platforms like GitHub or developer forums to find discussions about CI/CD failures. This insight will help you tailor your messaging to address their specific challenges.
- 02
Highlight observability gaps
Search for companies that have recently adopted new tools but face challenges with observability. Use LinkedIn to identify posts or articles discussing these struggles. Mentioning these gaps in your outreach can capture their attention.
- 03
Leverage recent product launches
Filter for developer tools companies in Spain that have recently launched new products. Use news aggregators or press release services to find this information. Acknowledging their recent efforts in your outreach can create a relatable context.
- 04
Address resource constraints
Identify companies that have recently downsized or restructured their engineering teams. Use LinkedIn to check for changes in staff size. Position your outreach around how your solution can help maximize productivity with fewer resources.
- 05
Follow up with technical insights
After initial outreach, follow up within a week with a case study or technical insight related to CI/CD or observability. Use email tracking tools to determine when your initial email was opened to time your follow-up effectively.
Can developer tools companies even receive your mail?
We measured the DNS of 587 developer tools companies, sampled evenly across company sizes, to see how many authenticate their own email. It matters in both directions: a domain that does not authenticate is a domain whose team is used to mail going missing — and if your own domain is in the gap, yours is the mail going missing.
Publishes a DMARC policy of quarantine or reject — the domain actually asks receivers to act on failures.
The gap is the finding: 27.4% of 1–10-person companies against 94.9% of the largest — 68 points apart. Small companies are where the unauthenticated domains are, and small companies are who most cold outreach is aimed at.
Where does your domain sit?
Same three lookups, run live against your domain. Nothing is stored and nothing is emailed to you.
How this was measured
Company domains were sampled within employee-count bands, then queried over public DNS for SPF (TXT at the apex), DMARC (TXT at _dmarc.) and MX. One domain per company, deduplicated. Anyone can reproduce any single row of this with dig.
DKIM is deliberately absent. A DKIM key lives under a selector that cannot be enumerated from outside the domain, so a company with flawless DKIM under a name we did not guess would be counted as having none. That would measure our guess list, not the industry.
Domains with no MX record are excluded rather than counted as failures — parked and redirect-only domains would otherwise drag every figure down and make the result an artefact of the sample.
Sampled within bands, so this describes the population of companies, not of employees: a 10-person company counts once, as does a 10,000-person one. Each band is at least 60 domains; bands below that are not published. Figures are percentages of the sample, not of the whole industry, and we publish no company names — only counts.

Questions
- Why do CTOs in developer tools ignore outreach about performance monitoring?
- CTOs might ignore such outreach if they believe their current tools are sufficient or if they are overwhelmed with vendor pitches. It's crucial to demonstrate a clear understanding of their specific challenges and offer tangible benefits that resonate with their operational goals.
- What common objections do CTOs have regarding new developer tools?
- Common objections include concerns about integration with existing systems, the learning curve for their teams, and potential disruptions during implementation. Addressing these objections with clear, concise solutions in your outreach can help overcome resistance.
- How can I effectively demonstrate value to a CTO in developer tools?
- To demonstrate value, focus on specific case studies or examples where your solution has improved operational efficiency or reduced downtime. Tailoring your message to their current challenges will resonate more than generic pitches.
- What timing is best for outreach to CTOs in Spain?
- The best timing for outreach is typically early in the week, preferably Tuesday or Wednesday mornings. This is when CTOs are likely to have more bandwidth to review new information and respond to outreach.
