Sarah's amazing. We first met Sarah while fundraising for our first startup and kept in touch over the years after Greylock passed on investing. When we were raising for our second company and reached out to pitch her, she asked thoughtful questions, set clear expectations, and respected our deadlines. After months of working with Sarah and Greylock, my impression of her has only gotten better. She’s really smart and quick (I often tell her to slow down so I can keep up), responsive (she'll text me back on Saturday morning within minutes), and respectful (doesn't show up late to meetings, follows through on promises). Strategically, she really tries to understand the problem that you are trying to solve for your customers and the business that *you* want to build. On top of all this, it's really clear that Sarah cares deeply about the founders she works with. I cannot recommend working with Sarah highly enough — you'll be really glad to have her on your cap table.

Great operator, has an incredible operating reputation from Dropbox (a part of the Dropbox mafia). With that said, he also has a bit of a reputation of being *savage*, operationally and when it comes to execution. Might be the type of person who you'd love to be on the same side of the table with, but not on the opposite

Really smart guy, great person to brainstorm ideas about business with. He's very much a bias towards kind of guy, often his advice is to "just do it and see." has good consumer intuitions. First round's office is pretty cool too, I believe they let portfolio founders work there.

Cyril is the dark night of startup seed rounds in SF. He's not flashy and doesn't do the fake twitter beef thing (which seems to be very on-brand for many other investors), but holy s*** does cyril know everyone. Even rounds of funding later, I still email cyril for intros. He's the dumbledore of seed-stage startups.

I first was in touch with Rodrigo in February 2019 when a passing conversation at a networking event turned into an introduction to the Programme Manager for the RebelBio pre-seed accelerator, London. I was asked to present and after having passed a first stage interview with Dr John Carrigan who was the scientific director for the accelerator programme, Rodrigo then arranged a call two days later. This was much more a drilling down into myself as a founder and why I had decided to not take a well-paid position on graduation from university but bootstrap a life science start-up. His direct-no-bullsh*t approach to life was refreshing to hear but gave an inexperienced founder some lessons on the importance for understanding every aspect of the business. Rabbit holes could be found but perhaps the questioning was more to do with my attitude and ability to learn. This was my first interaction with an investor. I had, however, managed to pass this interview and then onto Bill Liao where we had a conditional offer in conversation but had to amend areas of the business before the cohort start date. During this time, Rodrigo had offered to intro businesses that had gone through the accelerator. Both the good ones and ones were he openly acknowledged that the founders would probably say hard truths about the programme and about himself. This was rather refreshing but also a surprise to see that an investor was willing to open his chest of investments that didn't quite work out and introduce a discussion where I felt the founder would tell me the truth. Believe me. They did not hold back. The was a consensus that if I was not desperate for the money at the time or not wanting the moon-shot exit, then this would be a bad option. Conversations then dwindled and we did not amend the areas of the business and as such the terms sheet etc. were not issued and we did not join the RebelBio programme. I thought that would be the end of discussions but over the course of the 2019 year only one partner from the SOSV team came back for updates and that was Rodrigo. Over a 6-month period we had two/three 30 minute update meetings, where even though he had no stake in the business, offered introductions to other investors and founders of businesses that maybe of interest to help mentor me. During these discussions I would also ask his subjective opinion on some decisions I had to make and whether that would hinder an investor coming in later on. Having that was invaluable for me and comforting to have an independent view. In the meantime, the start-up had continued to progress through grant funding and when looking for the next areas of funding I decided to take another look at RebelBio website out of curiosity and noticed that RebelBio was missing from the SOSV website. Curious, I sent an email and got a reply the same day explaining that he was now heading up a new programme in NY called IndieBio (RebelBio merged into this), still for the SOSV fund. As we caught up, he was eager to see a slide deck and asked me to present to RebelBio that included Julie Wolf (Communications Director @IndieBio), Sam Lee and Stephen Chambers (Partner @IndieBio). Again, similar to the last presentation, Rodrigo facilitated introductions to both new businesses and old ones I touched base with the year before. It was interesting to see whether the same founders who had spoke well of him carried the same opinion and where they saw him as a benefit or hindrance. They described his “will to win” and “direct” approach to any discussions as something they benefited from and an element I had attributed to him previously. These discussions progress further to where I had the decision from him personally that he would take a bet on me and issued the procedure to sign the term sheets. The term sheets where an Accelerator Contract for Equity (ACE) and a Stock Purchase Agreement. An intro to the legal team also was helpful to answer questions I had on the terms enclosed in the documents, I also had other legal teams review this on my end. After all this and with the pandemic just beginning to kick up, I felt I needed to wait till to bring an investor in, so I declined. Rodrigo, I felt, respected the decision and, again, expecting conversations to drop soon after, we still catch up every so often now to this date 8 months on. I honestly feel, to the extent where I have written more here than in my English GCSE exam, that although he has no equity invested in my start-up, he most definitely is personally invested and is someone I could comfortably reach out to for a trusted opinion in the future.

Vas is trustworthy, thoughtful, and helpful. The process of him evaluating and ultimately investing in our company was fast and transparent. We caught up many times along the way, aside from board meetings, and he was always listening and nudging the team and me in what felt like the right direction. He was there when we needed him. After that ended, I've kept up with him and would love to have him on board any company I start.
