Huge shoutout to Kaushik Kulkarni, the Clay Expert, who came through in a clutch moment and helped me build a custom Clay table that pulls intent data and auto-generates a LinkedIn prospecting list. What stood out most wasn’t just his technical mastery (which is top-tier), but his collaborative spirit. Kaushik didn’t just solve the problem... he partnered with me. He asked thoughtful questions, listened closely, and built alongside me in a way that felt like a true extension of my team. It wasn’t a transactional experience... it was creative, fluid, and genuinely enjoyable. This won’t be a one-time project. We’re already gearing up for what’s next, and I’m excited to keep building with someone who brings both deep expertise and a team-first mindset. If you’re diving into Clay and want someone who can build smart with you, not just for you... Kaushik’s your guy.
Highly recommend Kaushik! He's an absolute pro at cold outreach, consistently booking 1 highly qualified meeting out of every 100 emails. Targeting is spot on, and his copy and pitches are always top-notch. If you’re looking to level up your outreach game, Kaushik is your guy!
Have been working with KK for a couple of months now. He’s a rare gem. Super strong technically. He’s one of those no code to MVP but can build complex tech as well types. Very impressed with his work. Not sure I should be writing this because I want more of his time lol. More than happy to answer any questions on working with him :)
KK is undoubtably one of the best outreach pro's I've had the pleasure of working with. From building lists of high intent B2B prospects to expert knowledge of both Clay and Instantly, we received positive results within the first day of campaign launch. I highly recommend Kaushik with his flawless copy and outreach approach that generates proper results.
Kaushik has been a vital asset to our team. He brings deep GTM engineering expertise paired with a consistently positive, can-do attitude. No matter the challenge, Kaushik tackles it with thoughtfulness and speed. He’s an excellent communicator proactively surfacing blockers, clearly sharing progress, and asking sharp scoping questions to keep projects moving smoothly. Working with him has been a pleasure.
Kaushik is a knowledgeable and talented Clay practitioner who has been instrumental in building out my team's capacity to source + build lists at scale. His understanding of the product's capability sets and limitations have been integral as we scale up our search business. I would not hesitate to recommend Kaushik for Clay-centric tasks like data-rich list-building.
I worked with Kaushik to build a lead enrichment system using Clay, and he was fantastic from start to finish. He moved quickly, communicated clearly, and delivered high-quality work. What stood out most was his depth in email outreach and enrichment systems—he consistently brought smart GTM-engineering ideas and proactive recommendations that made the final solution better. I’d happily work with him again and highly recommend him.
recently purchased the Apollo and LinkedIn Sales Navigator database from Kaushik and the experience has been excellent. The data was accurate, well-organized, and immediately actionable—helping us identify and connect with new clients quickly. Kaushik was responsive and transparent throughout the process, making the entire transaction smooth and reliable. Highly recommended for anyone looking to scale outreach with verified B2B data.
Kaushik's database gave me 90K+ SaaS companies with funding data, team info, and competitor links, all in one file. Building prospect lists that used to take days now takes minutes. If you're doing outbound to software companies, this is a no-brainer.
KK is the man! VERY knowledgable on the GTM side. VERY responsive. Has gotten me great results for my business and is the guy you need when you want sales support.
Kaushik helped us scrape our competitor’s leads at an affordable cost within a couple of hours. 100% recommended to run successful outreach campaigns
Kaushik's communication is on point, supported me on a time sensitive project and was able to deliver the leads quickly & effectively!
Kaushik was able to help me gather company data, in a very efficient manner. He's familiar with software, GTM and the funding process.
He is great at providing lists and data that we could use for outbound with our clients. Highly recommend working with him.
