I run Breaking Bits Security (<a href="https:&#x2F;&#x2F;breakingbits.com" rel="nofollow">https:&#x2F;&#x2F;breakingbits.com</a>). We work with a lot of the YC community. Our rates are also a lot more sane than most of the larger consulting shops since we have no sales, marketing or account management teams to support :).<p>We offer web application security assessments, mobile application security assessments and source code review. We also offer company training and reverse engineering services, but I&#x27;m assuming you are most interested in web app sec and source code review, correct?<p>Check us out if you&#x27;re interested, my email is in my profile. Good luck with whatever you choose.
