Tim Barrows

Bio

Tim Barrows is a general partner at Matrix, where he has invested in technology start-ups for thirty years. In his role as a lead investor and board member, Tim has assisted entrepreneurs in ushering ventures from their earliest stages through to successful outcomes. More than fifteen of the companies he helped establish and grow have gone onto successful acquisitions or initial public offerings.

Tim has advised and supported entrepreneurs across a range of technology sectors, including enterprise software, SMB-focused business services, communications and semiconductors. He has counseled entrepreneurs through multiple economic cycles and various technology booms, and has mentored many first-time CEOs.

Under Tim’s stewardship, Matrix Partners has delivered some of the highest performing funds of all time and expanded into international markets.

Prior to Matrix Partners, Tim worked in investment banking at Merrill Lynch White Weld, splitting his time between the technology group in corporate finance and the mergers and acquisitions group.  He was also active in several seed stage investments.

Tim joined Matrix Partners in 1984. Among the companies he has worked with over the years are OnDisplay, a provider of Web infrastructure software (IPO and later acquired by Vignette for $1.7 billion); Qihoo 360, the leading internet security company in China (Nasdaq: QIHU); SilverStream Software, a leader in Web services-oriented application development (IPO, later acquired by Novell); Starent Networks, the leading provider of infrastructure solutions for mobile carriers (Nasdaq: STAR); Sycamore Networks, a provider of multiservice network solutions (Nasdaq: SCMR); and Tivoli Systems, the leading provider of system management solutions for distributed systems (one of the top two IPOs in 1995, later sold to IBM).

While continuing to support entrepreneurs starting companies in the U.S., Tim leads the firm’s international efforts, which have included recruiting founding partners and establishing two new funds in Mumbai, India and Beijing, China.

On How I Got Here

I’ve always had curiosity around technology and a mind for business. I must have been born with the business side — my Dad was a professor of education and my parents met in the Peace Corps, so there were no term sheets or strategy discussions in the house growing up.  

I graduated from UC Berkeley right before Mosaic and Netscape changed everything. Pre-internet, the idea that you could be young and an entrepreneur was less obvious than it is today. It wasn’t until I went to Stanford business school that I clearly saw I wanted to be an entrepreneur.

My first venture was built in London creating a NASDAQ-style prediction market, now called Paddy Power Betfair – we made betting on sports, politics, or anything you want, into a financial instrument that can be traded just like a stock or an option. It took years to scale and there were many twists and turns. Today it’s the largest business of its kind in the world, with $2B+ in annual revenue and market capitalization of $9B+. I’m a small part of what ended up becoming a huge thing. It was a great ride and it put me on the map.

California called, and I knew it was where I wanted to build my life. I bought, with a co-founder, a business called eHow, a content site for all things How-To. Started in 1998, it went bankrupt in 2000 before we bought in 2004. We did a quick turnaround, had a great financial outcome, and out of that spun another business, wikiHow, that my co-founder still runs.

On Why I Invest

I have more talent for seeing an opportunity than I do for leading a big team. As an investor, I think I can really help people who are building businesses see around the next corner better and help with making the right decision a higher percentage of the time.

There are lots of people in this town with checkbooks. In the current investing environment, good ideas are not failing to see the light of day for a lack of funding. I’m proud of the reputation Matrix has built despite the noise — we get more entrepreneurs taking our money a second time than any firm because people like what we do for them.

I think founders choose to take investment from me personally because they feel they can trust me and that I’ll do the right thing by the business, regardless of how crazy things get. Being a founder is lonely — knowing your investor has got your back isn’t something you should have to compromise on.

Hardi Meybaum

Bio

Having built his own successful company with the support of Matrix Partners, when Hardi decided he wanted to support other entrepreneurs as a VC, he knew Matrix was the only place for him.

Hardi is a natural born entrepreneur. He was exposed to technology and computers from an early age in Estonia, and graduated from university with a degree in mechanical engineering. After a short stint in a large Estonian company where he felt stifled and unfulfilled, he quickly switched gears and started seeking out more entrepreneurial opportunities where he could apply unconventional solutions to big problems. A good example–in one of his first projects he transformed shipping containers into homes and offices spaces for those in need. Realizing his desire to change the way things are done, Hardi embraced the founder lifestyle and hasn’t looked back.

After three company starts, Hardi hit upon the idea for GrabCAD, moving to the US to build the company. He immersed himself in the Boston tech community and quickly heard about David Skok, Matrix GP. After learning about David’s knowledge in building companies and his helpful, founder focused approach, he knew he wanted David as a mentor and investor. Hardi took it upon himself to get introduced to David, and Matrix ended up funding GrabCAD and David joined his board.

From 2009 to 2014, Hardi built GrabCAD into the world’s leading cloud-based collaboration platform for engineering teams to manage, share, and view CAD files. He sold GrabCAD to Stratasys (NASDAQ: SSYS) in 2014, and continued to lead GrabCAD for the next year. With his team and community of 2.2 million engineers in good hands, he was ready to explore new things.

He spent time advising founders as a mentor and angel investor, and discovered that he loves engaging with entrepreneurs and helping them figure out difficult issues. He’s found his varied experiences as an entrepreneur can be critically helpful to other entrepreneurs. He’s able to help founders think through where markets are headed, what makes a great product, how to strike the right deal with customers and partners, and how to fundraise and manage a board. And, having felt the pain and difficulties of being a founder, Hardi understands more than most investors, what other founders are going through, from the lows to the highs of turning a great idea into a successful company.

Hardi says, “For me, there is nothing better than working with driven, smart people that are changing the way things are done. I can think of no job more fun and more fulfilling than being a VC and doing it at Matrix. I built GrabCAD out of the Matrix office when I first came to the US–I know everyone at Matrix incredibly well and have the deepest respect for each of them.”

Hardi is based in our Cambridge office and invests nationally across all areas of IT. He has a particular interest in vertical communities, hardware, and B2B SaaS. He believes that we are past the time of horizontal SaaS software and communities, and that the next phase of big companies will be built on mobile and cloud, and will focus heavily on niche verticals. He is also very excited by the disruption happening in hardware, which takes him back to his technical roots.

Hardi enjoys staying active outside of work, and likes to travel to new destinations to work on his kitesurfing and snowboarding skills. He loves spending time with his wife and two daughters, and has a long time love for everything science fiction.

Stan Reiss

Bio

A lifetime techie, Stan is driven by helping exceptional technologists grow their ideas into widely used products and services.

Born in Gdansk, a shipbuilding city in the north of Poland, Stan grew up at a time of social unrest and martial law. Computers were a novelty only seen at Dad’s office, and rotary dial phone calls were arranged by reservation.  When he and his family immigrated to the U.S. in 1982, Stan was amazed by the impact prevalent technology had on everyone’s life. He didn’t speak English but he could “talk” to the school’s Commodore Pet computer, and began coding at a young age.

Stan joined Matrix in 2000 after many years of engineering education, time spent developing chips at National Semiconductor, and learning how to talk to humans and think revenues and profits while with McKinsey’s technology practice.

At Matrix, Stan seeks out entrepreneurs looking to build companies founded upon disruptive technical innovation. His ambition is to utilize his combination of technical and market experience to help founders turn those innovations into thriving, profitable enterprises. Stan has partnered with tech entrepreneurs in a variety of areas, including communications (e.g., Acacia Communications), digital health (e.g., QPID), enterprise software (e.g., Mitro, Hyper9), components and materials (Xtalic).

His current interests include enterprise Internet infrastructure (especially security, applications of data and reasoning, and IT effectiveness), robotics, and digital health. He’s also unashamedly excited by any novel idea in an area no one’s thought of yet – after all it’s the innovators, not the VCs, that tend to identify the exciting new directions of technical progress.

Outside of the office Stan can be found outdoors: hiking, cycling, skiing, or cheering his kids on in various sports.

Antonio Rodriguez

Bio

Having been an engineer, product manager, founder, CEO, and executive, Antonio came to Matrix to back founders who think big and paint a picture of a future that is original and compelling.

Originally a native of Venezuela, Antonio’s love of technology began when he learned to program on an Apple II as a nine year old.  That early spark inspired him to become a hacker and serial entrepreneur.

Immediately before Matrix, Antonio was CTO of HP’s consumer Imaging and Printing division where he led a wide array of projects in the areas of mass customization, e-reading, mobile platforms, and next generation web platforms for content consumption.

He came to HP through the acquisition of Tabblo, where he was founder and CEO.  Tabblo, a Matrix-backed company, was a high-end photo site focused on bringing together the viral nature of online content publishing with the high margins of digital printing.

Prior to that, Antonio held a variety of engineering, product, and business development roles at MyPublisher (currently the leading photo book manufacturer in the US), abuzz Technologies (acquired by the New York Times), and the Boston Consulting Group.

Antonio’s area of focus include predictive analytics, post PC platforms, digital fabrication, and education technology.

For more on Antonio, check out his blog where he writes about technology, entrepreneurship, and whatever happens to be consuming his cycles. At the moment that consists of building an autonomous drone that broadcasts compelling iBeacon messages as it thoroughly confuses hipsters in search of their free kale smoothies.

Jared Sleeper

On How I Got Here

I’m from a small town in Northern Maine where my family has owned and operated a general store since 1914. Growing up, I worked with my father and grandfather doing whatever needed to be done: repairing the roof, cashiering, stocking shelves and (my favorite) demolition. I learned all about the challenges small businesses face against a big world. My dad woke before dawn each morning to open the shop. No excuses.

When I was twelve, I started investing in stocks. My first three were a biotech company, an oil driller and a shipwreck hunting company. I didn’t make much money in the end (see: Black Swan Treasure), but I did become addicted to studying businesses.

At Harvard, I led the college’s largest investment club and refocused it on fundamentals: understanding companies deeply and fostering fiercely open debate. I majored in economics but I thrived on different perspectives and loved arguing late into the night with archaeology students about the ethics of selling sunken treasure.

At Putnam, I started as an associate and over time became responsible for analyzing small and mid-size tech companies for $50bn of mutual funds. My work in ad-tech, consumer internet, cybersecurity and SaaS, led to investments in GrubHub, Delivery Hero, Criteo, Proofpoint, Uber, ServiceNow, Shopify and Wix.

On Why I Invest

I joined Matrix because while I love the intellectual challenge of investing, I’m energized by helping entrepreneurs change the world. My favorite founders have a vision for what the future will look like (even if it requires a little squinting), paired with a plan to make it happen, the drive to see it through and the nimbleness to adapt along the way.

Like so many founders, I saw that working with the team at Matrix is a special opportunity. They are ex-operators and domain experts with empathy and strong opinions in spades, which they use to relentlessly support and invest in promising entrepreneurs.

Dana Stalder

Bio

Dana Stalder knows what it takes to turn a scrappy start-up into a strong, independent company. Dana has managed nimble ventures as well as 2,500-person teams. He has sat on both sides of the table in acquisition talks and sold to consumers, small businesses and Fortune 500 companies alike. His experience cuts across multiple disciplines including sales, marketing, finance, technology and product management at companies such as eBay, Netscape and PayPal.

“My goal each day is to help entrepreneurs get where they want to go. I have been in their shoes, struggling to launch new businesses, and I have scaled high-growth public companies,” he says. “I am passionate about identifying future leaders and helping them develop and use their individual talents to make a lasting impact.”

Dana was born and raised in Silicon Valley, and studied business and economics at Santa Clara University. After college he worked at Ernst & Young advising technology companies such as Quantum, Sun Microsystems, Remedy, Netscape, and Intuit.

In 1994 he left to help build Netscape, then a nascent, few-month-old, pre-revenue company defining the ways in which consumers and enterprises were going to use the Internet. In his four-year tenure, Dana held several executive positions in finance, sales and operations.

Dana left Netscape after its sale to AOL in 1998 and became a member of the founding team of Respond.com, an early pioneer in online lead generation. There, he served as the company’s Vice President of Business Development and Chief Financial Officer.

Dana joined eBay in 2001. As Vice President of Internet Marketing, Dana managed the company’s global customer acquisition strategy and a hundred million-dollar Internet marketing budget. Dana was also responsible for eBay’s Strategic Partnership Group, which generated several hundred million in revenue from third party partnerships and media sales.

In 2004 Dana joined PayPal, where he managed all business operations, including product, sales, marketing and, eventually, technology. Dana started PayPal’s international business from scratch, and led PayPal’s expansion beyond the eBay platform onto other online retail sites. He also initiated a number of other startup projects, including PayPal Mobile and the PayPal Developer Platform.

Dana left PayPal in 2008 to join Matrix Partners, where he invests predominantly in FinTech, Consumer Marketplaces, and Enterprise Software.

On how I got here

My parents left the Soviet Union in search of a better life when I was very young. In San Francisco, they started out cleaning and painting homes. Today they’re entrepreneurs — they both code more than I do.

I grew up on early versions of the internet, hacking together my own games and sharing them on IRC. Nothing beats tinkering and building something for your friends.

I’m glad I didn’t take the cushy corporate job right out of school. My first two startup experiences worked out well enough but success was hard won — layoffs, pivots, failures, and painful fundraises during the 2008 crash. I learned far more than I would’ve on a smooth ride.

At Parse, we set out to change how developers built apps — reaching millions of developers and powering hundreds of thousands of apps. From writing the first lines of code, managing the acquisition to leading the team as a semi-autonomous unit inside Facebook, it was both hard and great.

I led all of Facebook’s developer products including early efforts to build a developer platform in Messenger. It was a big change. Product-market fit and scale trump all. Facebook focuses on only a few important things and re-evaluates methodically — which is a huge advantage.

On why I invest

Investing at Matrix is my way to continue building. From building startups to angel investing to working at Y Combinator, I’ve fallen hard for the gritty work of the early days.

The best startup ideas come from an obsession with fixing personal pain points. Even so, it takes exceptionally rare drive to chose the hard path and will something into existence from nothing.

The best thing about being a Founder-CEO is the privilege of leading a team that takes on your vision and mission as their own.

The hardest thing about being a Founder-CEO is managing your own psychology. You have to get comfortable with being very uncomfortable. You have to discount the daily blips. Internalize them, swallow them and steamroll through.

Tell me your war stories and I’ll tell you mine. I want to sympathize, offer guidance and suggestions. I care and will be there, no matter what.

Andrew Verhalen

On how I got here

After graduate school, I came west to work in the Microprocessor Group at Intel during the dawn of the PC industry.  The environment was intense as we raced to expand the market, but it was a great proving ground where I developed my management skills.

From there I moved to 3Com, just as companies were beginning to build corporate networks. I had the opportunity to recruit a team, help define and launch new products that propelled us to become the clear market leader.  As we scaled the business it became the revenue and profit engine for the company.

On why I invest

One of Matrix’s strongest assets as a firm is its long history. It’s ingrained in our culture to analyze our successes and failures as a team to make sure entrepreneurs can benefit from our extensive collective experience.

We invest in people, not companies. We strive hard to build mutual trust and respect with founders, otherwise we can’t help them.

Founders are navigating uncharted waters. We’re here to assist and advise, but they are on the front line. We help to recruit great talent, provide perspective, and avoid mistakes we’ve witnessed at other companies.

At board meetings, I mostly listen — I only comment on a few things I consider really important. I’m not there as a decision maker, but as a coach and mentor. Ultimately, the CEO has to decide what to do.

Controller

Samantha Belinkie

Bio

As controller I help ensure our financial reporting is accurate and timely. From auditing reports to managing capital accounts, my idea of success is giving the rest of the team the confidence to focus on innovating and executing.

My career began at a Big Four accounting firm, where I learned to navigate a range of industries — each with their own challenges. After completing my Masters program and earning my CPA, I landed at a large global private equity firm. I thrived in the fast-paced environment, and my role grew as I rose to manage a team of accountants.

Working in private equity gave me a bird’s eye view of the finance world, but the particulars were often hard to make out. At Matrix, it’s easy to connect the dots between our funds and the entrepreneurs deploying capital to build something great. The fact that the team here is so warm and personable has made the jump even more rewarding.

People are often surprised to hear I work in accounting, but it’s always appealed to me — like a puzzle waiting to be solved. Every equation has to balance, and there’s always an answer to be found. There aren’t many things in life that add up the way they should; I appreciate those that do.

Lauren Detro

Bio

I’ve always loved hearing people’s stories; they reveal so much more than what’s on the surface. Studying psychology gave me a way to channel that into helping others, and I began my career as a therapist. It was deeply fulfilling, but the burdens were heavy — and the field is bogged in bureaucracy.

I started at Matrix as an admin. I was drawn to the intelligence and kindness from everyone on the team — and to getting a courtside seat to an energizing industry.

A bit later on, I started contributing to our marketing efforts; before I knew it I was in meetings with partners, helping with portfolio company launch strategies and more. I can’t imagine many places that would have given me this opportunity.

It’s a privilege working closely with the team and our portfolio. Each partner is their own person, each founder is pursuing something much bigger than themselves. Helping identify the uniqueness in their perspectives is the key to effectively sharing their story.

I love the variety here: every time I go to reach for my next task, I find something new. From managing our brand, content and events, to engaging with the community and directing PR initiatives — the novelty keeps me on my toes and makes the work fulfilling.
