About
Michael Skok co-founded Underscore VC in 2015 after previously working as a venture investor at North Bridge Venture Partners. Earlier in his career he was an entrepreneur, building companies in enterprise big data and analytics (AlphaBlox, acquired by IBM) and security and consumer products (Symantec UK). He focuses on breakthrough technologies and disruptive business models such as open source, cloud, IoT, blockchain, VR/AR, and AI/ML, and taught at Harvard University for over a decade.

Beyond investing
- Charities
- Skok says he gives images away when requested for a good cause and publishes images for open use on Unsplash. No separate foundation, donation totals or structured philanthropic vehicle were found.
- Communities
- Underscore's open-source-inspired model allocates a 10% profit share in a supported company to selected Core Partners at no cost to founders. Mautic involved seven Core Partners and fifteen Core Syndicate participants; the annual Core Summit brought the community, portfolio and LPs together.
- More
- Underscore says Skok began at 15; his current personal biography says 16. Both agree that he programmed an HP-65 and built inventory and portfolio-management applications before university, so the one-year discrepancy is retained. Skok and Acquia biographies say teams he founded attracted more than $100 million in private equity. This is an aggregate self-reported company-financing figure, not his personal capital or proceeds. Skok's current biography says IBM acquired AlphaBlox in 2001, apparently conflating the end of his CEO tenure with the sale. IBM's contemporaneous July 14, 2004 announcement identifies later CEO Joe Guglielmi and expected closing that month; 2004 controls for transaction chronology. Skok dates his early North Bridge thesis to 2002 or 2003 in different first-person accounts. It anticipated cloud-delivered software and helped frame Demandware; priority over every comparable industry formulation is not claimed. Demandware's 2014 proxy says Skok joined its board in 2004, was independent, and served on compensation and nominating/governance committees. His self-reported record ends in June 2015, before Salesforce's 2016 acquisition. As an Acquia director Skok voted for Vista's majority transaction while personally declining liquidity and later leaving the board as a supportive shareholder. Dries Buytaert said Vista bought out initial investors, but Skok expressly said he and Underscore retained shares; this may reflect holder-level elections and should not be generalized to all North Bridge interests. Skok says his company-building skill came from success and early failure and is incorporating failed-venture case studies into Startup Secrets. He has not published a reliable named ledger of failed companies, investment losses or recoveries, so none is invented. Skok voluntarily states that a brain tumor disrupted his life in 2019 and ongoing health work led him to retire from active Underscore management. The firm describes the resulting succession as planned and multi-generational, not a performance or governance removal.

Founder fit — who Michael backs
Best fit is a bold, missionary founder who deeply understands a large, unavoidable problem, is uniquely qualified by experience or insight, can attract an exceptional team, listens and learns, and wants aligned community help. Skok prizes people before narrow themes, founder self-awareness, customer validation, a discontinuous rather than incremental advantage, and willingness to evolve roles as the company grows. Repeat and experienced teams matter, but he also supports academic founders and first-time entrepreneurs when problem insight and mission are strong.
Likely weak fits are idea-first pitches without a consequential problem; incremental feature advantages; latent aspirations presented as urgent necessities; gains too small to overcome switching cost and inertia; diffuse initial markets; teams lacking distinctive qualification or customer evidence; founders attached to title or ego over mission; valuation-led fundraising without company-building substance; and opportunities assigned to Skok merely because they appear in the current Underscore portfolio. These are synthesized from his teaching and are not a formal current exclusion list.
How to pitch
Start with the minimum viable problem and primary beneficiary, test it against the 4Us, quantify the gain/pain ratio, and use customers' words. Define a minimum viable segment before claiming a huge market. Present a compelling story—not a checklist—covering team, problem, value proposition, market, differentiated solution, business model, go-to-market, milestones, finances and funding ask. Explain why the founders are uniquely qualified and how the company can build unfair advantage. Validate with customers and references. For fundraising, distinguish Skok's advisory emeritus role from a current Underscore sponsor and confirm the actual decision partner, fund, check, reserves, governance and Core Partner expectations.
Stages: historical company formation and seed, historical North Bridge seed to growth, Underscore Seed to Series A at founding, current Underscore pre-seed and seed, firm-wide, select follow-ons, exceptional later-stage opportunities · Sectors: B2B software, SaaS and cloud services, open source, commerce and product experience, big data and analytics, cloud data infrastructure, AI and machine learning, IoT and scientific data, mobile and application management, cybersecurity, developer and workplace collaboration, supply-chain software, customer data and marketing automation, virtual and augmented reality, academic spinouts

Investment themes
12 documented themes from Michael's essays, talks and portfolio, grouped by what they say about founders.
▶More themes11
Everything as a Service2002
Companies increasingly outsource non-core capabilities to cloud-delivered services; Skok used this to anticipate SaaS commerce and other category shifts.
For founders: Show why a service model removes non-core work and creates enduring customer value, not merely recurring billing.
Open source as company and community engine2007
Skok backed commercialization around Drupal and R and developed an open-source-inspired venture model emphasizing community, transparency and shared economics.
For founders: Explain how community participation compounds product adoption and how commercial value aligns with contributors.
Cloud Intelligence2016
Connected people, places and things create data requiring filtering, machine learning, actionable analytics and secure scalable infrastructure.
For founders: Locate the company in the data-to-intelligence-to-action chain and prove why its layer is necessary.
Start with a minimum viable problem2012
A minimum viable product is directionless unless the customer problem and beneficiary are first made explicit.
For founders: Define whose problem is being solved, its current consequences and why action is required before demoing features.
The 4Us and gain/pain ratio2012
Test whether a problem is Unworkable, Unavoidable, Urgent or Underserved and whether the gain is roughly an order of magnitude greater than adoption pain.
For founders: Quantify urgency, switching cost, inertia and benefit rather than relying on generic faster-better-cheaper claims.
Minimum viable segment2016
Start with a tightly defined segment that shares acute needs and references, then expand from earned strength.
For founders: Name the first customers precisely and show why winning that niche creates a credible expansion path.
Mission before role and ego2019
Great entrepreneurs are missionaries and should let company needs, not attachment to titles, determine how roles evolve.
For founders: Demonstrate willingness to hire around weaknesses and change role as scale demands.
Story behind the perfect pitch2012
A complete pitch checklist is insufficient; founders must connect team, problem, value and market in a memorable causal narrative.
For founders: Build one coherent investment story with evidence and a clear ask rather than a sequence of disconnected slides.
Customer-led validation2013
Founders should prioritize capabilities around customer needs, identify the primary beneficiary and validate language with real buyers.
For founders: Bring direct customer evidence and describe differentiation in customer terms.
Aligned community as venture infrastructure2015
Capital is increasingly commoditized; curated operators can help source, select and support companies and share investment profit as Core Partners.
For founders: Assess whether the relevant experts are truly available and aligned, and select advisors who fit the company's immediate needs.
Failure must produce learning2013
Skok rejects both fear and romanticization of failure: experiments and early ventures are useful only when lessons alter the next decision.
For founders: Discuss failed tests candidly, specify what changed and avoid repeating unexamined assumptions.
▶Founders & company building1
Uniquely qualified people2012
Skok looks for founders whose experience, passion, insight and ability to recruit make them unusually suited to a significant problem.
For founders: Connect founder history and earned insight directly to the problem and required execution.

Colleagues at Underscore VC
Frequently asked questions
- Who is Michael J. Skok?
- He is a software entrepreneur turned venture investor and educator: former AlphaBlox CEO and North Bridge general partner, co-founder and current founding partner emeritus of Underscore VC, HBS Executive Fellow and creator of Startup Secrets.
- What did he study?
- Demandware's SEC-filed proxy says he holds a joint honors degree from Nottingham University in management science and engineering; his profile dates study to 1978-1981 and labels it a BS.
- Did he found Symantec?
- No. He describes himself as the UK founder and managing director who built Symantec's UK operation; he did not found the US parent company.
- When was AlphaBlox acquired?
- IBM announced and expected to close the acquisition in July 2004 for undisclosed terms. Skok's current biography says 2001, but that is the year his self-reported CEO tenure ended, not the documented sale year.
- What was his North Bridge record?
- From 2002 to 2014 he invested in early-stage software. Strong direct attribution includes Demandware, Acquia, Revolution Analytics, Apperian and Unidesk; other reported boards are retained as qualified rather than assumed deal leads.
- What happened to Demandware?
- It went public in 2012 and Salesforce agreed to acquire it in 2016 for approximately $2.8 billion cash. Those are company outcomes, not Skok's disclosed proceeds.
- What was his role in Acquia?
- He helped the founders form the company, led early North Bridge investment and served on the board. In 2019 he voted for Vista's majority deal, retained his personal shares and left the board.
- Why did he found Underscore VC?
- After interviewing hundreds of founders in a year-long listening tour, he co-founded Underscore in 2015 to pair early B2B software capital with an aligned operator community and shared economics.
- Does he still manage Underscore?
- No. Health demands following a 2019 brain tumor accelerated a planned succession. He is a founding partner emeritus and advisor; the current general-partner group manages the firm.
- Which Underscore investments are attributable to him?
- Strong first-party or official evidence connects him to Mautic, Moltin, Zaius, Coda, Salsify, TetraScience, CloudZero, Forge.AI and Cazena, with qualified involvement in project44, HelloTeam, FXP and BusRight. This does not make the entire Underscore portfolio his.
- What is his investment thesis?
- Back uniquely qualified people pursuing large B2B software shifts, especially SaaS/cloud, open source, commerce, data/analytics and AI, and support them with experienced operators. His historical Everything as a Service thesis evolved into Cloud Intelligence.
- What does he look for in founders?
- Mission, unusual qualification for the problem, bold ambition, customer insight, self-awareness, recruiting ability, a discontinuous advantage and willingness to learn and evolve.
- What are the 4Us?
- A Startup Secrets test asking whether a customer problem is Unworkable, Unavoidable, Urgent or Underserved. Skok pairs it with a gain/pain test asking whether benefit is roughly ten times adoption cost.
- What is Startup Secrets?
- A practical entrepreneurship curriculum created for Harvard Innovation Labs in 2012, covering value proposition, company formation, business models, go-to-market and pitching; its resources are free online.
