How to sell to CTOs at Developer tools companies in Singapore
CTOs in developer tools companies in Singapore are primarily measured on the speed of product delivery and system reliability. They respond to outreach that shows a deep understanding of their CI/CD challenges, particularly around integration and automation. Demonstrating knowledge of their existing tech stack and how your solution could enhance their observability will capture their attention.
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
- slow deployment times
- integration failures
- high operational costs
- system downtime
The playbook
- 01
Identify recent funding announcements
Search for developer tools companies in Singapore that have recently secured funding. Use platforms like Crunchbase or TechCrunch to filter for companies that have raised capital in the last 6 months. These companies are likely expanding their teams and may need support in scaling their CI/CD processes.
- 02
Highlight integration challenges
Craft your outreach to focus on the common pain points of integration within CI/CD pipelines. Reference specific tools they may be using, such as Jenkins or GitLab, and discuss how your solution can simplify their observability challenges. This specificity will resonate with their day-to-day experiences.
- 03
Leverage industry events
Monitor upcoming tech events or meetups in Singapore where CTOs are likely to attend. Customize your outreach to mention these events, offering to discuss best practices around API platforms or CI/CD strategies. This creates a natural context for a meeting request.
- 04
Address scalability concerns
In your follow-up communication, directly address scalability issues that arise during rapid growth phases. CTOs are often concerned about how to maintain system reliability while expanding. Position your outreach around solutions that can alleviate these pressures.
- 05
Request feedback on existing tools
Engage CTOs by asking for their feedback on tools they currently use for observability and CI/CD. This approach not only shows that you value their expertise but also opens the door for a conversation about potential improvements or alternatives that your solution can offer.
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 at developer tools companies ignore outreach about automation tools?
- CTOs may ignore outreach if it lacks relevance to their specific tech stack or if it doesn't address their immediate pain points. Many receive numerous emails daily, so generic messages fail to catch their attention. Personalization and demonstrating a clear understanding of their challenges are key.
- What triggers a CTO to respond to cold outreach?
- A CTO is likely to respond if the outreach addresses a pressing issue, such as improving deployment speeds or reducing system outages. Mentioning a recent industry trend or a specific challenge they face can also prompt a response, especially if it aligns with their current goals.
- How can I effectively follow up with a CTO?
- Effective follow-ups should reference previous conversations or specific points of interest discussed. CTOS appreciate concise communication that respects their time. Following up with insights or articles relevant to their challenges can also help keep the conversation going.
- What common objections do CTOs have regarding new tools?
- CTOs often express concerns about integration with existing systems, the potential for disruption during implementation, and the overall cost of new tools. Addressing these objections upfront in your outreach can help build trust and demonstrate that you understand their priorities.
