Florian Heinemann

Who they are

Florian Heinemann is Founding Partner at Project A Ventures — co-founded JustBooks in 1999 (acquired by Amazon via AbeBooks) and co-founded antibodies-online.com, an online marketplace for life science reagents.

Person

Florian holds a Ph.D. in Innovation Management and Entrepreneurship from RWTH Aachen, a Master's from WHU – Otto Beisheim School of Management, and did a stint as Visiting Scholar at Wharton — an unusually academic foundation for someone who has spent most of his career as a serial builder. His first venture, JustBooks, launched in 1999 as an online book marketplace and was eventually acquired by Amazon through AbeBooks; he also co-founded antibodies-online.com, a marketplace for antibodies and life science reagents. From there he moved into operational roles — senior work at Jamba! and iLove, then Managing Director at Rocket Internet, the Berlin company-builder that industrialised e-commerce cloning across emerging markets. In April 2012 he co-founded Project A Ventures from scratch, and has stayed there ever since — a long tenure that now spans more than thirteen years. He sits on the board of Trade Republic, the German neo-broker that has become one of Europe's largest consumer fintech companies. The through-line is a founder who turned operator, then turned investor — each stage building on direct experience of what it takes to start and scale a company from zero. Possibly — his occasional public writing stays in the practical, operator-to-founder register rather than broad market commentary.

Company

Project A Ventures is a European early-stage VC firm that Florian co-founded in April 2012, now managing approximately USD 1.5B in AUM. Its differentiator is an in-house team of 100+ operational experts — engineers, marketers, data scientists — embedded to work directly with portfolio companies alongside capital. That model was unconventional at founding and has since become a recognisable format in European venture. After more than a decade of operation, the firm is firmly established in Berlin as one of the continent's larger early-stage platforms.

Market

Project A competes in the European early-stage VC market alongside firms such as Earlybird, Cherry Ventures, and HV Capital, as well as the European arms of larger global funds. The 'capital plus operational support' positioning occupies a distinct niche — closer to a hybrid operator-investor than a pure financial backer — which gives it a specific angle in founder conversations about more than just check size.

Network

No direct edge data is available for Florian's immediate network. His most prominent named board engagement is Trade Republic, connecting him to one of Europe's fastest-growing consumer fintech companies. His Rocket Internet background places him in the extended network of Berlin's first-generation internet operators.

How they likely show up

  • Ph.D. in Innovation Management plus Wharton visiting scholar → likely approaches investment theses with structured analytical rigour, not purely gut instinct.
  • Co-founded JustBooks in 1999 and Project A in 2012, alongside antibodies-online.com → pattern of active building across decades; this is not a career investor, it's a serial founder who moved into VC.
  • Managing Director at Rocket Internet before co-founding Project A → trained in high-velocity, operationally intense company-building; will have strong opinions on execution speed and operational KPIs.
  • Long-tenure investor (13+ years at a single firm he co-founded) → thinks in long arcs; unlikely to be impressed by short-term narratives or quick pivots.
  • Project A's 100+ in-house expert model reflects his own background → he likely engages at the operational level, not just the board level; expects founders to be receptive to hands-on input.
  • Possibly — occasional public writing signal suggests he communicates selectively rather than broadcasting; conversations likely carry more weight than posts.

Conversation tips

  • → Come with specific operational metrics — his Rocket Internet background means he'll probe unit economics and execution cadence, not just vision.
  • → Reference the Project A operational model specifically (the in-house expert team) — it's his founding bet, not just a feature, and he'll engage if you've thought about what that means in practice.
  • → If Trade Republic comes up, treat it as context for the kind of scaling complexity he finds interesting — consumer fintech at European scale.
  • → Don't pitch the idea alone; show the build — he has founded companies himself and will care about what you've already done, not just what you plan to do.
  • → His academic background (Ph.D., Wharton) means he's comfortable with frameworks — a structured argument lands better than a purely narrative pitch.

Toolbox

Openers

  • Open on JustBooks — he co-founded an online book marketplace in 1999 that ended up in Amazon's hands via AbeBooks, which means he's been through the full founder arc before he ever wrote a check.
  • Reference the Project A in-house expert model directly — building a 100+ person operational team inside a VC firm was an unusual structural bet in 2012, and asking what convinced him it was the right architecture is a genuine opener.
  • Mention antibodies-online.com — co-founding a B2B marketplace for life science reagents alongside a VC career is an unexpected detail that signals genuine range and curiosity beyond consumer internet.

Discovery questions

  1. When you built the in-house operational team at Project A, which function — engineering, marketing, data — turned out to matter most to early-stage founders, and did that surprise you?
  2. Having gone from founding JustBooks in 1999 to Rocket Internet's company-building machine to running your own fund — where do you think the Rocket Internet model got operational intensity right, and where did it create blind spots for founders?
  3. As a board member at Trade Republic, what does watching a consumer fintech scale to that size change about how you evaluate financial-services bets at early stage?

Avoid

Don't treat him as a pure financier — he has founded and operated companies himself, and framing the conversation around valuation multiples or fund mechanics without engaging the operational side will read as shallow.
